Periodic movements of animals in response to seasonal changes or reproductive instinct. Hormonal changes are the trigger in at least some animals. Most migrations are made for reasons of climatic change, feeding, or breeding.
Mammals of the families Delphinidae (ocean dolphins), Iniidae, Lipotidae, Pontoporiidae, and Platanistidae (all river dolphins). Among the most well-known species are the BOTTLE-NOSED DOLPHIN and the KILLER WHALE (a dolphin). The common name dolphin is applied to small cetaceans having a beaklike snout and a slender, streamlined body, whereas PORPOISES are small cetaceans with a blunt snout and rather stocky body.

Against the current: an inter-oceanic whale migration event. (1/32)

Humpback whales seasonally migrate long distances between tropical and polar regions. However, inter-oceanic exchange is rare and difficult to document. Using skin biopsy samples collected in the Indian Ocean and in the South Atlantic Ocean, and a genetic capture-recapture approach based on microsatellite genotyping, we were able to reveal the first direct genetic evidence of the inter-oceanic migration of a male humpback whale. This exceptional migration to wintering grounds of two different ocean basins questions traditional notions of fidelity to an ocean basin, and demonstrates how the behaviour of highly mobile species may be elucidated from combining genetics with long-term field studies. Our finding has implications for management of humpback whale populations, as well as for hypotheses concerning cultural transmission of behaviour.  (+info)

Larval development and settlement of a whale barnacle. (2/32)

Larval development and settlement of whale barnacles have not previously been described, unlike intertidal barnacles. Indeed, the mechanisms of the association between barnacles and whales have not been studied. Here we describe the larval development and settlement of the whale barnacle, Coronula diadema, and possible involvement of a cue from the host in inducing larval settlement. Eight-cell stage embryos were collected from C. diadema on a stranded humpback whale, incubated in filtered seawater for 7 days, and nauplius larvae hatched out. When fed with Chaetoceros gracilis, the nauplii developed to stage VI, and finally metamorphosed to the cypris stage. The larval development looked similar to that of intertidal barnacles with planktotrophic larval stages. The cyprids did not settle in normal seawater, but did settle in polystyrene Petri dishes when incubated in seawater with a small piece of skin tissue from the host whale. This strongly suggests the involvement of a chemical cue from the host whale tissue to induce larval settlement.  (+info)

Southern Hemisphere humpback whales wintering off Central America: insights from water temperature into the longest mammalian migration. (3/32)

We report on a wintering area off the Pacific coast of Central America for humpback whales (Megaptera novaeangliae) migrating from feeding areas off Antarctica. We document seven individuals, including a mother/calf pair, that made this migration (approx. 8300km), the longest movement undertaken by any mammal. Whales were observed as far north as 11 degrees N off Costa Rica, in an area also used by a boreal population during the opposite winter season, resulting in unique spatial overlap between Northern and Southern Hemisphere populations. The occurrence of such a northerly wintering area is coincident with the development of an equatorial tongue of cold water in the eastern South Pacific, a pattern that is repeated in the eastern South Atlantic. A survey of location and water temperature at the wintering areas worldwide indicates that they are found in warm waters (21.1-28.3 degrees C), irrespective of latitude. We contend that while availability of suitable reproductive habitat in the wintering areas is important at the fine scale, water temperature influences whale distribution at the basin scale. Calf development in warm water may lead to larger adult size and increased reproductive success, a strategy that supports the energy conservation hypothesis as a reason for migration.  (+info)

Structure of the cerebral cortex of the humpback whale, Megaptera novaeangliae (Cetacea, Mysticeti, Balaenopteridae). (4/32)

Cetaceans diverged from terrestrial mammals between 50 and 60 million years ago and acquired, during their adaptation to a fully aquatic milieu, many derived features, including echolocation (in odontocetes), remarkable auditory and communicative abilities, as well as a complex social organization. Whereas brain structure has been documented in detail in some odontocetes, few reports exist on its organization in mysticetes. We studied the cerebral cortex of the humpback whale (Megaptera novaeangliae) in comparison to another balaenopterid, the fin whale, and representative odontocetes. We observed several differences between Megaptera and odontocetes, such as a highly clustered organization of layer II over the occipital and inferotemporal neocortex, whereas such pattern is restricted to the ventral insula in odontocetes. A striking observation in Megaptera was the presence in layer V of the anterior cingulate, anterior insular, and frontopolar cortices of large spindle cells, similar in morphology and distribution to those described in hominids, suggesting a case of parallel evolution. They were also observed in the fin whale and the largest odontocetes, but not in species with smaller brains or body size. The hippocampal formation, unremarkable in odontocetes, is further diminutive in Megaptera, contrasting with terrestrial mammals. As in odontocetes, clear cytoarchitectural patterns exist in the neocortex of Megaptera, making it possible to define many cortical domains. These observations demonstrate that Megaptera differs from Odontoceti in certain aspects of cortical cytoarchitecture and may provide a neuromorphologic basis for functional and behavioral differences between the suborders as well as a reflection of their divergent evolution.  (+info)

Blowing bubbles: an aquatic adaptation that risks protection of the respiratory tract in humpback whales (Megaptera novaeangliae). (5/32)

Cetaceans (whales, dolphins, and porpoises) have developed extensive protective barriers to exclude water or food from the respiratory tract, including valvular nostrils, an intranarial elongated larynx, and a sphincteric soft palate. A barrier breach can be lethal, as asphyxiation may occur from incursions of water (drowning) or food (choking). Humpback whales (Megaptera novaeangliae), however, exhibit a possibly unique and paradoxical behavior concerning respiratory protection: they release a "bubble cloud" (a cluster of tiny bubbles) underwater from the mouth. How they do this remains unclear. This study tests the hypothesis that the larynx plays a role in enabling bubble cloud emission. The anatomy and position of the larynx was examined in seven specimens of Megaptera novaeangliae. Results indicate that the epiglottis can be manually removed from behind the soft palate and placed in the oral cavity during dissection. Unlike that of toothed whales (odontocetes), the humpback whale larynx does not appear to be permanently intranarial. The elongated and trough-shaped epiglottis may function as a tube when placed against the undersurface of the soft palate and, thus, facilitate channeling air from the larynx to the oral cavity. The pointed tip and lateral edges of the epiglottis fit tightly against the undersurface of the soft palate, perhaps functioning as a one-way valve that lets air out but prevents water from entering. Bubble cloud generation likely involves air passing directly from the larynx into the oral cavity, and then expulsion through the mesh of the baleen plates. A laryngeal-oral connection, however, compromises the anatomical aquatic adaptations that normally protect the respiratory tract. A potential for drowning exists during the critical interval in which the larynx is intraoral and during re-insertion back to the normal intranarial position. The retention of this risky behavior indicates the importance of bubble clouds in predator avoidance, prey capture, and/or social signaling.  (+info)

Spondylitis in a humpback whale (Megaptera novaeangliae) from the southeast Pacific. (6/32)

A 7.25 m long male humpback whale (Megaptera novaeangliae) with spondylitis was found beached on August 13, 1994 at Ancon, Ecuador (2 degrees 23' S, 80 degrees 47' W). The condition involved at least 11 vertebrae, 7 lumbar (L4 to L11) and 4 caudal (Ca1 to Ca4). Partial fusion of vertebrae was observed as a result of intervertebral bony proliferation, likely impeding full motion. The relatively young age of this specimen and the severity of the deformities suggest an infectious, rather than degenerative, process. The gross findings are most consistent with some type of spondyloarthritis. Although this condition has previously been identified in a number of cetacean species, the pathogenesis, population impact and ecologic implications have not been fully assessed. This is the third case described for humpback whales and the first for a humpback whale from the SE Pacific.  (+info)

'Megapclicks': acoustic click trains and buzzes produced during night-time foraging of humpback whales (Megaptera novaeangliae). (7/32)

Humpback whales (Megaptera novaeangliae) exhibit a variety of foraging behaviours, but neither they nor any baleen whale are known to produce broadband clicks in association with feeding, as do many odontocetes. We recorded underwater behaviour of humpback whales in a northwest Atlantic feeding area using suction-cup attached, multi-sensor, acoustic tags (DTAGs). Here we describe the first recordings of click production associated with underwater lunges from baleen whales. Recordings of over 34000 'megapclicks' from two whales indicated relatively low received levels at the tag (between 143 and 154dB re 1 microPa pp), most energy below 2kHz, and interclick intervals often decreasing towards the end of click trains to form a buzz. All clicks were recorded during night-time hours. Sharp body rolls also occurred at the end of click bouts containing buzzes, suggesting feeding events. This acoustic behaviour seems to form part of a night-time feeding tactic for humpbacks and also expands the known acoustic repertoire of baleen whales in general.  (+info)

Neuromuscular anatomy and evolution of the cetacean forelimb. (8/32)

The forelimb of cetaceans (whales, dolphins, and porpoises) has been radically modified during the limb-to-flipper transition. Extant cetaceans have a soft tissue flipper encasing the manus and acting as a hydrofoil to generate lift. The neuromuscular anatomy that controls flipper movement, however, is poorly understood. This study documents flipper neuromuscular anatomy and tests the hypothesis that antebrachial muscle robustness is related to body size. Data were gathered during dissections of 22 flippers, representing 15 species (7 odontocetes, 15 mysticetes). Results were compared with published descriptions of both artiodactyls and secondarily aquatic vertebrates. Results indicate muscle robustness is best predicted by taxonomic distribution and is not a function of body size. All cetaceans have atrophied triceps muscles, an immobile cubital joint, and lack most connective tissue structures and manus muscles. Forelimbs retain only three muscle groups: triceps (only the scapular head is functional as the humeral heads are vestigal), and antebrachial extensors and flexors. Well-developed flexor and extensor muscles were found in mysticetes and basal odontocetes (i.e., physeterids, kogiids, and ziphiids), whereas later diverging odontocetes (i.e., monodontids, phocoenids, and delphinids) lack or reduce these muscles. Balaenopterid mysticetes (e.g., fin and minke whales) may actively change flipper curvature, while basal odontocetes (e.g., sperm and beaked whales) probably stiffen the flipper through isometric contraction. Later diverging odontocetes lack musculature supporting digital movements and are unable to manipulate flipper curvature. Cetacean forelimbs are unique in that they have lost agility and several soft tissue structures, but retain sensory innervations.  (+info)

In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the recent separation of humpback whales into Distinct Population Segments (DPS) for listing under the US Endangered Species Act, including four DPSs in the North Pacific (Western North Pacific, Hawaii, Mexico, and Central America) with different conservation statuses. The projects objective was to conduct a comprehensive characterization of humpback whale movements during breeding, migration, and feeding periods by tagging animals in both a feeding area (southeastern Alaska) and a breeding area (Hawaii). In order to obtain representative results, the sampling plan called for two field efforts at each site, with Pacific Life ...
Rorqual whales (Balaenopteridae) lunge at high speed with mouth open to nearly 90 degrees in order to engulf large volumes of prey-laden water. This feeding process is enabled by extremely large skulls and mandibles that increase mouth area, thereby facilitating the flux of water into the mouth. When these mandibles are lowered during lunge-feeding, they are exposed to high drag and therefore may be subject to significant bending forces. We hypothesized that these mandibles exhibited a mechanical design (shape and density distribution) that enables these bones to accommodate high loads during lunge-feeding without exceeding their breaking strength. We used quantitative computed tomography (QCT) to determine the three-dimensional geometry and density distribution of a pair of sub-adult humpback whale (Megaptera novaeangliae) mandibles (length = 2.10 m). QCT data indicated highest bone density and crosssectional area, and therefore high resistance to bending and deflection, from the coronoid ...
In a marvelous example of animal communication and culture, researchers have described how humpback whale songs sweep across the Pacific in just a few years.
An animals body condition provides valuable information for ecophysiological studies, and is an important measure of fitness in population monitoring and conservation. While both the external body shape of an animal, as well as its internal tissues (i.e. fat content) can be used as measures of body condition, the relationship between the two is not always linear. We compared the morphological body condition (external metric obtained through aerial photogrammetry) of migrating humpback whales (Megaptera novaeangliae) with their outer blubber lipid concentration (internal metric obtained through blubber biopsy sampling) off south-west Australia early and late in the breeding season (spanning ∼4.5 months). The external body condition index of juvenile and adult humpback whales decreased with 26.9 (from 18.8 to −8.1%) and 12.0 percentage points (from 8.6 to −3.4%) between the early and late phase, respectively. In contrast, we found no intra-seasonal change in blubber lipid concentration, and ...
This morning was a beautifully sunny day out on the water but you could certainly feel the autumn chill in the air! We journeyed out in search of whales and very quickly found a Humpback whale named Orion (BCX1251). Orion was in a travelling pattern so while he was spending lots of time on the surface we werent seeing many views of his tail flukes so we headed over to an area where another Humpback whale had been spotted. This whale was much larger than Orion so was most likely a female as the females are larger than the males in this species. Our second Humpback gave us several fantastic tail flukes as well as a very close up view of her blowhole as she passed near the stern of the vessel. On our way home we stopped in at Race Rocks Ecological reserve to view our large colony of Stellar and California Sea Lions.. ...
By Nadine Pinnell. After many decades during the mid to late 1900s, when it was very rare to see a humpback in B.C.s coastal waters, these whales are returning to the B.C. coast. Commercial whaling of the 1800 and 1900s had severely reduced populations across the North Pacific. Prior to whaling, it is estimated that there were over 15,000 humpback whales in the North Pacific ocean including a population of as many as 100 humpbacks returning yearly to the Strait of Georgia. It has been reported that these whales would often enter Vancouver Harbour and Burrard Inlet. During the 20th century an estimated 200,000 humpback whales were killed world-wide, reducing the world population by 90%. Due to this large decline, the International Whaling Commission ended whaling for humpbacks in all oceans in 1966. By this time, the North Pacific humpback population was reduced to an estimated 1200 to 1400 individuals. Estimates, based on research conducted in the early 1990s, suggest that the humpback ...
Whales from both poles migrate long distances to breed in tropical waters. Smithsonian scientist Hector M. Guzman and Fernando Félix at the Salinas Whale Museum in Ecuador tagged 47 humpbacks with satellite transmitters to understand how the humpbacks Southeastern Pacific population moves within breeding areas.. Our work fills an informational void: weve known these whales move between feeding areas and breeding areas, but we hadnt characterized their movements, and we couldnt exactly pinpoint the range of the breeding area, said Guzman, marine ecologist at the Smithsonian Tropical Research Institute (STRI) in Panama. Now we know that individuals move between countries within the breeding season and that their entire breeding area extends approximately 2,600 kilometers of non-straight coastline from Costa Rica to Peru.. For years, scientists have identified individual humpback whales (Megaptera novaeangliae) based on their unique fluke and dorsal fin patterns. In this study funded by ...
The rope was wrapped several times around the tail of the whale and it was also lodged in its mouth. The whale was very exposed and vulnerable in front of the shark. It seems that before the Marine Animal Entanglement Response crew from the Center for Coastal Studies arrived at the scene the whale was pretty badly injured on its left flank. The shark that attacked it was 15-foot-long.. When they discovered the whale the research team was studying the gases which humpback whales exhale. The whale was quite young and it was discovered on Stellwagen Bank which is a popular place where whales come to feed. It is five miles north of Provincetown.. Dr. Jooke Robbins, director of Humpback Whale Research at the Center for Coastal Studies said that when she first saw the whale floating with its back at the surface she thought that it was just resting. She also remarked:. ...
In an on-going project in collaboration with researchers at the Sea Mammal Research Unit of the University of St. Andrews (Scotland), the levels of reproductive and stress hormones are measured in blubber biopsy samples and blow samples collected from humpback whales. Reproductive hormone levels, particularly progesterone, have been measured in cetacean blubber samples and blow samples as indicators of pregnancy in various cetacean species. Other studies have shown, that high progesterone levels are indicative of pregnancy. Therefore, we can collect information on pregnancy rates in our humpback whale population, as well as, calf survival rates, when females are seen the following season with or without a calf.. In the same matrices, the blubber and the blow, the stress hormone cortisol will also be measured. In their natural environment, animals experience a variety of environmental and anthropogenically influenced conditions, which can induce a physiological stress response. Stress responses ...
Recently, I have been rethinking my workflow and processing techniques. I am not talking about a total overhaul of the way that I edit, but rather becoming more efficient and effective. Processing underwater images requires much more effort than above water images, particularly if I want a gray whale swimming through a blue background. For this reason, I have been holding off on editing my new underwater humpback whale images until now.. Tony Wu and I co-lead an exciting Humpback Whale Photography Tour in both Alaska and Tonga last summer. This beautiful portrait is from our first encounter with a friendly mother and calf in Tonga. Momma was resting about 20′ below the surface as the curious calf swam over to check me out and pretty much ran me over. We did not actually make contact, but if I would have extended my arm bent at the elbow I would have been able to touch it. I created this image using my Canon 5DmkIII and Canon 17-40mm f4 lens inside my Ikelite 5DmkIII housing with an 8″ dome ...
South Pacific humpback whales were devastated by commercial whaling in their Antarctic feeding areas during the 20th century. Understanding migratory connections and current abundance of these isolated breeding stocks is crucial for the allocation of historical Antarctic catches in population dynamic models used to assess current recovery. However, only a small number of migratory connections have been documented between Oceania breeding stocks within the South Pacific and feeding areas in the Antarctic. In addition, little is known about abundance of these stocks which encompass a vast oceanic region. For this thesis I first used mixed-stock analysis (MSA) to allocate migratory connections from four Antarctic feeding areas (n=142) to seven South Pacific breeding stocks (n=1,373), including four in Oceania, based on genetic marker frequencies. The use of this method was justified by the breeding stocks showing genetic differentiation at the haplotype level with an F[subscript ST] value of 0.027 ...

Assessing marine soundscapes provides an understanding of the biological, geological and anthropogenic composition of a habitat, including species diversity, community composition, and human impacts. For this study, nine acoustic recorders were deployed between December 2016 and June 2017 off six Caribbean islands in several Marine Parks: the Dominican Republic (DR), St. Martin (SM), Guadeloupe east and west (GE, GW), Martinique (MA), Aruba (AR), and Bonaire (BO). Humpback whale song was recorded at five sites on four islands (DR, SM, GE, GW, and MA) and occurred on 49-93% of recording days. Song appeared first at the DR site and began 4-6 weeks later at GE, GW, and MA. No song was heard in AR and BO, the southernmost islands. A 2-week period was examined for the hourly presence of vessel noise and the number and duration of ship passages. Hourly vessel presence ranged from low (20% - DR, 30% - SM), medium (52% - MA, 54% - BO, 77% - GE) to near continuous (99% - GW; 100% - AR). Diurnal patterns were
One feature that stood out in the humpback whale brain was the modular organization of certain cells into islands in the cerebral cortex that is also seen in the fin whale and other types of mammals. The authors speculate that this structural feature may have evolved in order to promote fast and efficient communication between neurons. The other notable feature was the presence of spindle cells in the humpback cortex in areas comparable to hominids and in other areas of the whale brain as well. Although the function of spindle neurons is not well understood, they are thought to be involved in cognitive processes and are affected by Alzheimers disease and other debilitating brain disorders such as autism and schizophrenia. Spindle neurons were also found in the same location in toothed whales with the largest brains, which suggests that they may be related to brain size.. The authors note that spindle neurons probably first appeared in the common ancestor of hominids about 15 million years ...
It was a windy start to the day, but that does not deter whales, so we set out to find them! Leaving the Capital City behind us, we started our search south and west in the deep blue waters of the Strait of Juan de Fuca. Even amongst the whitecaps, we spotted the tall, bushy blow of a humpback whale! With massive lungs and two blow holes, these cetaceans pump out a mighty mist each time they breathe!. Cruising near the surface, and not keen on diving deep, our humpback appeared to be sleeping. Whales have a special form of sleep where they shut down half of their brain at a time, preventing them from drowning. They are still able to navigate, swim, and take those ever important breaths while one side of their brain gets a rest. They can alternate which side of their brain is asleep and which side remains awake until they are fully rested! Natures master multi-taskers!. We then visited the 157 year old lighthouse, Race Rocks, where many different species of pinnipeds, seals and sea lions, rested ...
The University of Alaska Museum (UAM) Mammal Collection houses the largest collection of marine mammal specimens in North America. Its holdings include specimens from more than 12,000 walrus, 15,000 seals, 1,100 sea lions, 3,200 sea otters, and 1,100 cetaceans (whales, porpoises, and dolphins). The collection contains specimens from every species found in Alaskan waters, however, most cetacean specimens consist of tissue samples only with very few skeletons available for research. The large size of most whales and porpoises coupled with the remote sites where they are typically found beachcast, make salvaging a whole carcass arduous at best.. On June 28, 2016, an adult male humpback whale washed up, freshly dead, near Hope, Alaska. A necropsy was performed, and tissue samples were collected by Dr. Pam Tuomi and biologists from the Alaska Sea Life Center and the National Marine Fisheries Service the following day. No cause of death has been determined. The carcass was set loose and the tide took ...
This has no cropping..... The whale was that close.....a great experience.... The Humpback Whale (Megaptera novaeangliae) is a baleen whale. One of the larger rorqual species, adults range in length from 12-16 metres (40-50 ft) and weigh approximately 36,000 kilograms (79,000 lb). The Humpback has a distinctive body shape, with unusually long pectoral fins and a knobbly head. It is an acrobatic animal, often breaching and slapping the water. Males produce a complex whale song, which lasts for 10 to 20 minutes and is repeated for hours at a time. The purpose of the song is not yet clear, although it appears to have a role in mating. Found in oceans and seas around the world, Humpback Whales typically migrate up to 25,000 kilometres each year. Humpbacks feed only in summer, in polar waters, and migrate to tropical or sub-tropical waters to breed and give birth in the winter. During the winter, Humpbacks fast and live off their fat reserves. The species diet consists mostly of krill and small fish.
ABSTRACT: In the Southern Ocean, humpback whales Megaptera novaeangliae were depleted by commercial whaling operations during the 20th century, but many populations now appear to be recovering. Previous surveys of whale distribution along the western Antarctic Peninsula (WAP) suggested that humpbacks feed on krill swarms over the continental shelf during the summer, but little is known about their movements and densities during autumn, when krill begin to seek inshore refugia for overwintering. Here we present estimates of humpback whale densities in some inshore regions of the WAP during the late autumn. We surveyed 653.9 km of track line in the Gerlache Strait and adjacent bays during 26 April to 1 June 2009. We detected 371 groups of humpback whales in a distance sampling framework that allowed us to calculate estimates of whale density along track lines in open and enclosed habitats within our study area. Density estimates along track lines ranged from 0.02 to 1.75 whales km−2; the highest ...
Dear colleagues, As part of a larger bioenergetic study on baleen whales, I am looking for data on right whale and humpback whale morphometrics and body condition from carcasses (strandings, commercial/scientific catches, and similar). I am interested in data from all age classes (adult, juvenile, calves). Knowing that detailed data on these two species is quite scarce, I am looking for any of the following information (I am obviously not expecting to find all this information from the same animals): Morphometrics: -Body length (as well as distance between different body parts) -Girth (or half girth) (single or multiple sites) -Blubber thickness (single or multiple sites) -Total body weight -Blubber weight -Muscle weight -Visceral fat weight -Bone weight -Weight of other internal organs (heart, kidney, liver) -Stomach size/volume Chemical composition: -Blubber lipid concentration (total lipids, protein and water) -Muscle lipid concentration -Visceral fat lipid concentration -Bone lipid ...
Marine mammals, such as whales, have a high proportion of body fat and so are susceptible to the accumulation, and associated detrimental health effects, of lipophilic environmental contaminants. Recently, we developed a wild-type cell line from humpback whale fibroblasts (HuWa). Extensive molecular assessments with mammalian wild-type cells are typically constrained by a finite life span, with cells eventually becoming senescent. Thus, the present work explored the possibility of preventing senescence in the HuWa cell line by transfection with plasmids encoding the simian virus large T antigen (SV40T) or telomerase reverse transcriptase (TERT). No stable expression was achieved upon SV40 transfection. Transfection with TERT, on the other hand, activated the expression of telomerase in HuWa cells. At the time of manuscript preparation, the transfected HuWa cells (HuWaTERT) have been stable for at least 59 passages post-transfection. HuWaTERT proliferate rapidly and maintain initial cell ...

Acoustic playback experiments, behavioural response studies (BRS) and controlled exposure experiments (CEE) seek to identify and describe potential responses of animals to natural or synthetic acoustic stimuli. Playback experiments (in which animal sounds are played back) have been carried out since the late 1950s on a variety of species including insects (Alexander, 1961; Haskell, 1957), birds (Ficken and Ficken, 1970; Roche, 1966; Verner and Milligan, 1971), fish (Fish, 1968), seals (Watkins and Schevill, 1968), reindeer (Espmark, 1971) and cetaceans (Morgan, 1970). However, there is a distinct lack of published playback experiments in marine mammals compared with terrestrial animals. A report prepared in 2006 found that in a 5 year period, over 200 playback experiments were carried out on bird species compared with only 46 experiments on marine mammals (Deecke, 2006). Since that report (to date), only a few more playback studies on a marine mammal species have been presented in the ...

But it is too early to know whether cetacean morbillivirus killed three humpback whales and one pygmy sperm whale that have stranded since July 1 between the U.S. states of Massachusetts and Georgia, said Teri Rowles, director of the marine mammal health and stranding response program for the National Oceanic and Atmospheric Administrations fisheries service. A fourth humpback whale was too decomposed to allow reliable testing and results are not yet available on two other pygmy sperm whales, she said.. The humpback population has rebounded, but the species is still listed as endangered.. There are too many unknowns right now, Rowles said. We would be concerned if indeed there is an outbreak of this virus in humpback whales causing clinical disease and mortality. Sometimes, she said, a marine population can carry a virus without it causing widespread harm.. There have been 14 humpback strandings - when dead or dying animals wash ashore - along the East Coast this year, double the six-year ...
The Great Whale Trail is a collaboration between Greenpeace and scientists working on humpback whales in the South Pacific.. With financial support from Greenpeace, humpback whales have been tagged by the Cook Islands Whale Research and Opération Cétacés (New Caledonia). The whales are now being tracked via satellite as they migrate from breeding and calving areas in the tropical South Pacific to the feeding grounds of the Southern Ocean.. Check out the early results. This project will produce important information on the movements and migratory destinations of humpback whales from small, unrecovered populations off Rarotonga (Cook Islands) and New Caledonia.. Greenpeace is communicating this critical non-lethal scientific research to the wider public as part of their campaign against Japans unnecessary lethal research in the Southern Ocean Whale Sanctuary.. On their journey, the humpbacks, like hundreds of thousands of other whales, face a range of threats including ship strikes, ...

Last August, in addition to seeing blue whales, we also encountered many humpback whales (Megaptera novaeangliae). In particular, we spent quite a bit of time near a mother humpback whale and her frisky calf. The calf was waving pectoral fin(s) in the air and being generally rambunctious. Apparently, an adult humpbacks pectoral fins are the largest in the world and can extend to over 15 feet. The calf seemed to be waving hello (and then good-bye) to all on the whale watch boat ...
Two groups of whales, the humpback whale and the subspecies of blue whale found in the Indian Ocean, are known to produce a series of repetitious sounds at varying frequencies known as whale song. Marine biologist Philip Clapham describes the song as probably the most complex in the animal kingdom.[24]. Male humpback whales perform these vocalizations often during the mating season, and so it is believed the purpose of songs is to aid mate selection.[8] Whether the songs are a competitive behavior between males seeking the same mate, a means of defining territory, or a flirting behavior from a male to a female is not known and the subject of ongoing research.[citation needed] Males have been observed singing while simultaneously acting as an escort whale in the immediate vicinity of a female. Singing has also been recorded in competitive groups of whales that are composed of one female and multiple males.[citation needed]. Interest in whale song was aroused by researchers Roger Payne and ...
The humpback puffer, Tetraodon palembangensis, also known as Pao palembangensis, is a species of poisonous freshwater pufferfish mainly distributed in Southeast Asia (Thailand, Laos, Malaysia and Indonesia). Despite interesting biological features, such as its very inactive nature, tetrodotoxin production and body expansion mechanisms, molecular research on the humpback puffer is still rare because of the lack of a high-quality reference genome. Here, we reported a first chromosome-level genome assembly of an adult humpback puffer, of which the genome size is 362 Mb with ~1.78 Mb contig N50 and ~15.8 Mb scaffold N50s. Based on the genome, ~61.5Mb (18.11%) repeat sequences were also identified, and totally 19,925 genes were annotated, 99.20% of which could be predicted with function using protein-coding function databases. Finally, a phylogenetic tree was constructed with single-copy gene families from ten teleost fishes. The humpback puffer genome will be a valuable genomic resource to illustrate
Commercial over exploitation resulted in the depletion of the North Pacific population of humpback whales. A major component of this population winters in Hawaiian waters, where reproductive activities occur. There are no apparent identifiable trends in the status of this population. This may be due to inconsistent survey effort, the imprecision of survey techniques that are unable to detect small changes, no measurable trend, or one or any combination of these factors. During the winter breeding season, humpback whales are found within the 100-fathom isobath and shallower waters around the main Hawaiian Islands. Cow-calf pairs, in particular, demonstrate an affinity for waters of less than 50 fathoms. It appears that size, depth, and substrate of shallow bank areas are important elements in the distribution of humpback whales on their wintering grounds. The sea-surface temperature in Hawaiian waters ranges from 23.2 to 24.2 C during the winter breeding season and is at the low range of water
Every year in Puerto Vallarta Mexico, the most acrobatic of all whales, the Humpback, visits the Bay of Banderas in order to reproduce and give birth. Its arrival begins around mid to late October and extends to around end of March. During that time, some female whales give birth while others reproduce before returning to their feeding grounds in the north.
RIMPAC has been subject to intense public criticism for decades. In Hawaii, many associate the war games with the bombing of Kahoolawe, which was for years a major component of RIMPAC. Green says the non-incident of 2006 highlights the Navys unwillingness to take basic precautions that would lessen the likelihood of marine mammal fatalities. That the Navy insists on testing active sonar at night is telling, she says, but more telling is the fact that they are testing sonar in the prime breeding ground for humpback whales.. Encompassing approximately 1,218 square nautical miles, the Hawaiian Islands Humpback Whale National Marine Sanctuary is the winter home to two thirds of the North Pacifics humpbacks. The whales return each year to breed, calve and nurse their young in the warm, shallow waters of the worlds most isolated island archipelago. But in these very waters, between the islands of Maui, Lanai, and Kahoolawe, lies the U.S. Shallow Water Submarine Torpedo Training Range. There, ...
I saw an ad for an insurance company where a mother humpback whale cavorts in the ocean with her calf. The voiceover tells how protective the whales are to their young even, guiding the calf to the surface for its first breath. Humpback whales dont buy insurance - they just leave their kids with whatever wisdom about survival they can impart. When it comes to youth sports, parents see survival training as pushing their kids. I often hear parents exhorting their children with, Youve got to get on the select team and You need to be a starter. Theres a line between encouragement and expectation which is often slippery and vague. Knowing when to push and knowing when to let them swim on their own ends up being relatively simple for whales and terribly complicated for humans. But then humpbacks only have to worry about blubber hunters and orcas. Humans have to worry about getting on the right team, into the right college, and finding a home in a good school district. We parents have already ...

NBC News republished the following article by Kacey Demer, which is entitled How Satellites Might help save the Whales and which was originally published on Live Science:. First drones, and now satellites are allowing scientists to spy on whales - for research, that is.. Though they are massive animals, whale populations are difficult to monitor, according to researchers. Drones have been used to capture footage of whales, and now scientists are turning to even higher-flying help. Researchers in Australia are using satellite imagery to track local humpback whale populations, reported the Australian Broadcasting Corp. (ABC).. Humpback whales were considered an endangered species under the Endangered Species Act of 1973. However, the U.S. National Marine Fisheries Service lifted the whales endangered status last year as a result of successful conservation efforts. But despite this success, the migratory whales are difficult to track, and many population estimates are largely speculative, ...
The dominance of fossil rorqual skeletons at Cerro Ballena, across all bone-bearing levels, evokes a modern stranding event, whereby many individual cetaceans are beachcast, either dead or alive. Mass stranding events for socially gregarious species of toothed whales are well documented [36], but mass strandings for rorquals are rare. The most compelling analogue is a rorqual mass stranding of 14 humpback whales (Megaptera novaeangliae) over the course of five weeks along approximately 50 km of coastline around Cape Cod, MA, USA in 1987-1988 [35]. This assemblage included males, females and one calf, whose necropsies showed no signs of trauma or predation. Tissue assays of Atlantic mackerel (Scomber scombrus), from stomach contents, revealed high concentrations of saxitoxins, which are dinoflagellate neurotoxins. This evidence, along with the documented aberrant behaviour of one of the dying whales, and the geographical and temporal spans of the event, pointed to the previously unrecognized ...
Evaluating increased human interactions with humpback whales off the West Coast, specifically ship strikes and entanglements in Dungeness crab gear.

[more ▼]. Whale remains (a left and right mandible, scapula, humerus and fragmentary radius and ulna as well as parts of the cranium and rostrum) belonging to a probable humpback whale (Megaptera cf. novaeangliae) were found in the well-described sabkha sequence exposed in the Musaffah Industrial Channel, Abu Dhabi, United Arab Emirates. More precisely, the whale remains were found in a series of sediments representing a range of lagoonal facies. The sediments surrounding the whale bones were age-dated at approximately 5200 14C yrs BP and are herefore interpreted to correspond to the previously documented late Flandrian sea-level peak, receding a fall in sea-level which culminated in the supratidal sabkha overprint of the carbonates. associated with ...
ABSTRACT: Understanding the factors influencing habitat selection is critical to improving management and conservation plans for large whales. Many studies have linked the distribution of cetaceans to basic environmental features such as underwater topography and sea surface temperature (SST), but the mechanisms underlying these relationships are poorly understood. Dynamic mesoscale processes like thermal fronts are prime candidates to link physiographic factors to whale distribution because they increase biological productivity and aggregate prey. However, previous studies of large whales have found little evidence of such associations, possibly because they were not at the appropriate spatio-temporal scales. We quantified the relationship between SST fronts and the distribution of blue Balaenoptera musculus, finback B. physalus, humpback Megaptera novaeangliae and minke B. acutorostrata whales in the northern Gulf of St. Lawrence. We compared the distribution of 1094 whale sightings collected ...
I have been thinking of whales this week and remembering when I first saw a big one very close-up, so at the start of my podcast you can hear the sound, recorded underwater in the Atlantic Ocean of a humpback whale communicating with other whales..

Some of those efforts were successful, but unfortunately, many whales died…... The moment when I first saw a whale close-up is one of the memories etched on my mind. I was on the bow of Irelands first entry in the Round the World Yacht race in the Atlantic in May of 1990 when it happened. Suddenly, a huge whale was alongside us, so close I felt I could touch it.

An evoked-potential audiogram was measured for an Indo-Pacific humpback dolphin (Sousa chinensis) living in the dolphinarium of Nanning Zoo, China. Rhythmic 20 ms pip trains composed of cosine-enveloped 0.25 ms tone pips at a pip rate of 1 kHz were presented as sound stimuli. The dolphin was trained to remain still at the water surface and to wear soft latex suction-cup EEG electrodes used to measure the animals envelope-following evoked potentials to the sound stimuli. Responses to 1000 rhythmic 20 ms pip trains for each amplitude/frequency combination were averaged and analysed using a fast Fourier transform to obtain an evoked auditory response. The hearing threshold was defined as the zero crossing point of the response input-output function using linear regression. Fourteen frequencies ranging from 5.6 to 152 kHz were studied. The results showed that most of the thresholds were lower than 90 dB re. 1 mu Pa (r.m.s.), covering a frequency range from 11.2 to 128 kHz, and the lowest threshold ...
May 3, 2017 - See a great white shark binge eat a dead humpback whale. Filmed off the coast of southern California, the shark feasted on the whale for more than 18 hours. Famous for their prowess as predators, little is known about their more docile scavenging behaviors. They have been observed regurgitating already eaten food to make room for more calorically rich meat. While sharks have frequently been observed hunting, scavenging is less often seen.

May 17 is Endangered Species Day, and according to Endangered Earth, there are currently more than 16,300 endangered plant and animal species across the globe.However, dozens of species have been delisted in the last few decades, due in part to the 1973 Endangered Species Act, which strengthened protections for endangered animals.According to the Washington Post, animals like the humpback whale, the bald eagle, the American alligator, the black-footed ferret, the Grizzly bear, the Florida
Yet another windy day on the Kohala Coast meant we had to cancel a few trips…but on our Breakfast with the Whales cruise on Seasmoke out of Anaehoomalu Bay, we did get to see some action. We watched a Mom with her active baby - baby breached 3 times. We also saw some breaches in the distance (though it was too windy to get to those whales). And we had a close encounter with two big adult Humpbacks who decided to surface about 40 feet from us. On the Whales and Cocktails cruise, we saw a couple of whales breaching in the distance just as we left the bay. The wind was still pretty strong, so we decided not to go out to see them, but we did count 10 breaches between the two of them. We headed north towards the Mauna Lani instead, where we found a Mom/Baby/Escort pod. Baby breached 3 times right near the boat, and then we saw a huge tail lob and multiple pec slaps from the adults in the group. After that, we found a third pod of adults and as the grand finale, one of them breached right next to ...
Once the winter breeding season is over, the whales migrate back to the poles where their main food source prospers. The whales feed using baleen plates which act as giant filters to trap thousands of fish in one gulp. Humpbacks are cooperative feeders and employ different tactics while hunting including bubble net feeding. This is accomplished by multiple whales blowing bubbles through their blowholes and forming a circle around fish that confines them to a smaller area. So the whales get more fish in their mouths for less energy. Whales consume about 4,400 - 5,500 pounds of plankton, krill, and fish every day during their feeding season (120 days). Such a large amount is necessary to build up blubber stores for the long journey to warmer waters for breeding where they wont eat for an entire season. ...
We have shown that a thermal (IR) imaging-based system is a useful tool for detecting whales across a wide range of environmental conditions. Whale blows, produced primarily by humpbacks, were perceptible in ,70% of thermal (IR) images up to distances of 3 km, across a range of platform heights (16 to 49.8 m MSL), air and sea surface temperature combinations (12°C vs 10°C and 21°C vs 25°C; AT vs SST, respectively), and at wind force levels ,BFT4. Detection functions for the thermal (IR) system generally followed the pattern expected for point transect sampling. Distance to detection peaks ranged from ca. 0.5 to 3 km. Differences in peak location were attributed to platform height (lower platforms resulted closer detection peaks) and animal behavior. Wind force was also found to influence peak location, though this was also shown to be a function of platform height (greater wind force resulted in a closer peak at the lowest platform height only). Dense fog was found to impede the detection ...
The largest of them have hearts the size of compact cars, with a beat that can be detected two miles away. A small child could crawl through their larger blood vessels. Yet the subjects of the new IMAX film Whales manage to be remarkably elusive and mobile in spite of their immense girth. The humpbacks, one of several species profiled, make an annual pilgrimage from Hawaii to Alaska in search of a square meal. Photographed by Al Giddings (The Abyss, The Deep) and narrated by Star Treks Patrick Stewart, Whales is the first IMAX feature sponsored by the National Wildlife Federation. Ultimately, the film raises more questions than it answers. It states, for instance, that little is known of the routes these giant mammals take on their globe-spanning migrations. So why not tag them with radio transmitters? (A News of the Weird item a few weeks ago reported that scientists have even developed a microprocessor for attaching to cockroaches!) However, as a primer on the largest creatures ever to ...
The whale-watching tour is a leading attraction of the Virginia Aquarium and Marine Science Center in Virginia Beach. The area draws humpback and fin whales.
The final page of the booklet shows a two-sided page of lyrics; the front page of mine shows Like a Dove by The Disciples (with what looks like a picture of the imagined album cover), and Wishes of the Imagination on the reverse side. Booklet credits at the bottom of the page.. The first CD is the 14 songs that make up Pain Stained Morning, the first Humpback Oak release of 1994. The first song Void comes up, and it sounds very much like strummin REM, and Leslies voice sounds a lot like Michael Stipes here. Void is a bit dull-ish; better by far is Deep Door Down, which jangles and grooves, and Lucifer, which has some sophisticated songwriting, spooky symbolism, great melodies, and a gutsy solo. Finer Life is a bit sweet, but has great production. Cretin 1″ (and, later on, Cretin 2″) is a 30-second fragments of songs, sung in a very broad American voice, that isnt really that interesting.

The main Hawaiian Islands, closer to the equator than Key West, Florida, constitute the most tropical state in the union. Isolated in the middle of the Pacific, the islands have some of the sweetest air, cleanest ocean, and gentlest climates on the planet. Except for when the smoke from the volcano drifts in, floods wash raw sewage out to sea, or a typhoon roars across the land. Hawaii, the most fossil fuel dependent state, is also an ecological paradox. With 175 natural communities and 11 out of 13 of the worlds climate zones, the islands still suffer from mass extinction … more than 1,000 native species lost since human settlement!. Im remembering a morning in Maui last February. Were sipping coffees at sunrise in a little cove at the edge of Haleakala Volcano National Park.

In metazoan adherens junctions, β-catenin links the cytoplasmic tail of classical cadherins to the F-actin-binding protein α-catenin. Phosphorylation of a Ser/Thr-rich region in the cadherin tail dramatically enhances affinity for β-catenin and promotes cell-cell adhesion in cell culture systems, but its importance has not been demonstrated in vivo. In this paper, we identify a critical phosphorylated serine in the C. elegans cadherin HMR-1 required for strong binding to the β-catenin homolog HMP-2. Ablation of this phosphoserine interaction produces developmental defects that resemble full loss-of-function (Hammerhead and Humpback) phenotypes. Most metazoans possess a single gene for β-catenin, which is also a transcriptional coactivator in Wnt signaling. Nematodes and planaria, however, have a set of paralogous β-catenins; for example, C. elegans HMP-2 functions only in cell-cell adhesion, whereas SYS-1 mediates transcriptional activation through interactions with POP-1/Tcf. Finally, our ...

Anyone whos used a mobile for voice calls may have noticed that the background noise often sounds like speech or chirps. The characteristics of speech presumably have some features in common with birdsong and others not, and speech compression is presumably optimised for speech. However, there are other species which produce sounds somewhat speech-like but not identical, for instance birdsong, whale song and sounds made by other primates. Other species make more regular sounds, for instance cicadas and crickets.. So, my idea is this: find a method of sound compression which is lossy but optimised for species. It falls into two parts. One exploits characteristics common to all sound produced by animals, from cicadas to cockerels. The other is tweaked according to the species, the aim being to produce an output which the species concerned cant distinguish from the real thing, with the option of choosing compression optimised just for that species or for two different species. This would be ...

We started our Wednesday off on a nice, calm ocean, but the whales were anything but calm! On our Breakfast with the Whales Cruise, we saw 2 different Mom/Baby/Escort pods. We stayed with each of them for quite awhile…and the calf from the second pod delighted us when she breached 3 times right next to the boat! We also saw pec slaps and tail lobs from different adults, and when we dropped the hydrophone, we heard some very clear songs. For a grand finale on this cruise, another pod of whales swam right under the boat. Captain Scotty turned off the motors, and was able to see the whales on our depth sounder…and to top it off, the whales then decided it would be a good idea to pop up 5 feet from the boat…we couldnt believe our luck (or their curiosity). As the wind came up through the day, we saw lots more surface activities. On our Whales and Cocktails Cruise, we saw multiple breaches, pec slaps and tail lobs. We also saw several peduncle throws and some other splashes (not sure which ...
PROVINCETOWN, Mass. -- They call it whale watching. Whale searching would be more appropriate. Most of our time aboard the Dolphin VI was spent carefully scanning the choppy waters off the coast of this trendy Cape Cod community, hoping for a glimpse of the graceful creatures who sometimes make their home there. ``There`s a sighting at 9 o`clock,`` naturalist Peggy Christian said over the loudspeaker. Quickly, all of us who had been looking on the starboard (that`s the right) side of the boat ran over to the port (that`s left), and looked out to see if the whale she had spotted would surface again. Sure enough, just the very top of the finback whale was visible slicing through the whitecapped waters. At least we could say we`d seen a whale.

By Tyler Murphy/518Life. 1. To start the lunge, find an area with ample room. The space in front of you should be at least equal to your height. To begin, stand straight, arms down, head facing forward, with your feet hip-width apart. Relax your shoulders and keep the chin up.. 2. Step forward with one leg, lowering the hips but keeping them even. The forward foot should land with the knee directly above it, forming a right angle with the leg. Dont overextend your foot ahead of the knee or bend the joint past the ankle. Your back foot rolls forward onto the toes. The back knee should end up below your hips pointing at the ground with the calf parallel to the floor, forming another right angle.. 3. Push off the forward leg using the heel and pull back to the starting position. Keep your posture straight and try not to let your hips sway. Alternate legs and repeat the exercise.. 4. Strive to complete three sets with 20 alternating lunges for each. Remember to always engage your core - the ...

  • We used network-based diffusion analysis to reveal the cultural spread of a naturally occurring foraging innovation, lobtail feeding, through a population of humpback whales ( Megaptera novaeangliae ) over a period of 27 years. (
  • In the austral autumn we observed an extremely high density (5.1 whales per km 2 ) of humpback whales ( Megaptera novaeangliae ) feeding on a super-aggregation of Antarctic krill ( Euphausia superba ) in Wilhelmina Bay. (
  • We report on a female humpback whale ( Megaptera novaeangliae ) first identified by natural markings off Brazil that subsequently was photographed off Madagascar. (
  • The severe depletion of humpback whales ( Megaptera novaeangliae ) throughout the Southern Hemisphere [ 6 ] and apparent inconsistencies in the regional patterns of recovery [ 7 ] make understanding of regional movement patterns a considerable conservation concern. (
  • Predators of humpback whales include orcas (killer whales) and humans. (
  • Killer whales are not always successful in their attacks, which is why many humpback whales bear scars from orcas' teeth. (
  • These included physical barriers such as nets or boats, and playing the sounds of killer whales - known predators of humpback whales. (
  • In spite of the relative scarcity of information on many cetacean species, it is important to note in this context that sperm whales, killer whales, and certainly humpback whales, exhibit complex social patterns that included intricate communication skills, coalition-formation, cooperation, cultural transmission and tool usage," the authors state. (
  • Newborn humpback whales 'whisper' to their mothers to avoid being overheard by killer whales, researchers have discovered. (
  • Such quiet communication helps reduce the risk of being overheard by killer whales nearby, she believes: "Killer whales hunt young humpback calves outside Exmouth Gulf, so by calling softly to its mother the calf is less likely to be heard by killer whales, and avoid attracting male humpbacks who want to mate with the nursing females. (
  • A pod of killer whales springs up, trapping you and then knocking you off the ice. (
  • But then a giant humpback whale bursts out of the water, pushing the killer whales back. (
  • Once it manages to beat the killer whales away with its fins, the whale lets you off, so you can swim to safety. (
  • Marine ecologist Robert L. Pitman witnessed it in one of dozens of documented encounters of humpback whales defending other animals from killer whales. (
  • Because adult humpbacks are so enormous compared to killer whales, they're practically invulnerable to their attacks. (
  • Their article looks at 115 documented interactions between humpback whales and killer whales, reported by 54 different observers between 1951 and 2012. (
  • The majority of the time, humpbacks initiated the interactions, almost exclusively with mammal-eating killer whales, as opposed to their fish-eating relatives. (
  • Eighty-nine percent of the time the killer whales were not attacking other humpback whales, but a different species entirely. (
  • When killer whales hunt, they silently stalk their prey, but once they attack they're vocally frenzied. (
  • If it's kin selection, perhaps the humpbacks are hoping to make killer whales think twice about attacking humpback calves. (
  • Scientists are beginning to recognize a pattern in humpback whale behavior around the world, a seemingly intentional effort to rescue animals that are being hunted by killer whales. (
  • Marine ecologist Robert Pitman observed a particularly dramatic example of this behavior back in 2009, while observing a pod of killer whales hunting a Weddell seal trapped on an ice floe off Antarctica. (
  • It's as if humpback whales everywhere are saying to killer whales: pick on someone your own size! (
  • In 89 percent of the recorded incidents, the humpbacks seemed to intervene only as the killer whales began their hunt, or when they were already engaged in a hunt. (
  • A recent rise in sightings of the massive mammals can be attributed to a cleaner harbor and the resurgence of a feeder-fish species called Menhaden , whale-watchers have said. (
  • Understanding if they're separate populations or not is very important, as right now regulatory agencies are discussing whether humpback whales should be delisted from the Endangered Species Act or not, and they want to get a good idea of all the stocks of whales out there for such a decision," Lammers said. (
  • Although some other whale species also appear to be rebounding in the southern oceans, humpbacks seem to be faring the best, Dr. Friedlaender said. (
  • This might mean such whales are more intelligent than they have been given credit for, and suggests the basis for complex brains either evolved more than once, or has gone unused by most species of animals, the researchers said. (
  • The authors estimated that survivorship, the average probability of an adult whale surviving from one year to the next is among the highest reported anywhere for this species. (
  • Queensland researchers say the current population of humpback whales is the highest ever recorded and they are concerned at the rapid rate at which the species is populating. (
  • UQ's Dr Michael Noad says whale numbers could blow out to 50,000, putting pressure on the species to survive. (
  • They are readily identified by enormous, wing-like flippers, which are far longer than in any other whale species. (
  • Newser) - In attempt to determine whether the humpback whales still need to be saved, the government is reviewing the marine mammals' place on the endangered species list for the first time in a decade. (
  • the species name (" novaeangliae ") refers to New England, where the humpback whale was first described scientifically. (
  • Some large whale species, including the humpback, are now less threatened with extinction, according to the cetacean update of the 2008 IUCN Red List. (
  • "Humpbacks and southern right whales are making a comeback in much of their range mainly because they have been protected from commercial hunting," says Randall Reeves, Chair of the Cetacean Specialist Group of the IUCN Species Survival Commission, who led the IUCN Red List assessment. (
  • As well as being a majestic and endangered species, the humpback whale is also a public symbol of Glacier Bay," said superintendent Tomie Lee. (
  • The unlawful taking (killing) of humpback whales is prohibited by both the Endangered Species Act and the Marine Mammal Protection Act. (
  • Thus, a knowing failure to maintain a "slow, safe speed" when near humpback whales constitutes a violation of the Endangered Species Act and Marine Mammal Protection Act and carries the identical penalties of the taking violation. (
  • Federal authorities took most humpback whales off the endangered species list Tuesday, saying their numbers have recovered through international efforts to protect the giant mammals. (
  • But the species has been bouncing back since an international ban on commercial whaling took effect in 1966. (
  • Marta Nammack, the fisheries service's Endangered Species Act listing coordinator, said that's because the population is estimated at only about 400 whales. (
  • For instance, many species possess multi-chambered stomachs even though there is no obvious advantage to having such an arrangement as whales do not chew cud! (
  • Nonetheless, news of the proposed marine habitat brought cheers from conservationists, because when the rule is ratified, there can be added protections for species at risk, like the Pacific humpback whale. (
  • Back in 1970, humpback whales were listed as endangered under the Endangered Species Conservation Act and again under the Endangered Species Act (ESA) in 1973. (
  • Humpback whales are a threatened species that can grow up to 60-feet long, weigh 25-to-40 tons, and have a lifespan of 50 years, according to NOAA. (
  • A humpback whale makes its way along Australia's east coast during the species' annual migration. (
  • Humpbacks were endangered decades ago due to whaling, but international protection has helped them rebound so well that they are now listed as a "species of least concern. (
  • Migratory species such as humpbacks face several challenges related to changing environmental conditions which alter their migration timing. (
  • A new study published online November 27, 2006 in The Anatomical Record, the official journal of the American Association of Anatomists,compared a humpback whale brain with brains from several other cetacean species and found the presence of a certain type of neuron cell that is also found in humans. (
  • Through an international ban on commercial whaling and protections under the Endangered Species Act and the Marine Mammal Protection Act, the North Pacific humpback whale population has begun to increase. (
  • The decision to downgrade the humpback whale's 'threatened' status comes just two months after the federal government lost a major court battle with environmental groups over four at-risk species, one of which was the humpback whale. (
  • The feds' recent move to downgrade the protection of humpback whales comes just two months after it lost a lawsuit to five environmental groups including Ecojustice and the David Suzuki Foundation, in which courts declared that government had 'unlawfully' delayed recovery of four at-risk species threatened by the proposed Enbridge Northern Gateway pipeline. (
  • The Pacific Humpback Whale was one of those four species. (
  • Though the species of humpbacks population is improving, we're not out of the woods yet and the legal protection should stay in place," she told the Vancouver Observer. (
  • Back in February, Ecojustice staff lawyer Sean Nixon had stated that it was "unacceptable" for government to continue to miss deadlines in the Species at Risk Act to protect the Pacific Humpback Whale, Nechako White Sturgeon, Marbled Murrelet and Southern Mountain Caribou. (
  • But t he Harper government has so far neglected to do so for humpbacks and another 170 species. (
  • On Tuesday, federal authorities removed nearly all populations of humpback whales from the endangered species list, as one of the Earth's largest mammals has bounced back from the effects of widespread commercial whaling and other environmental dangers. (
  • The clearance for the majority of humpback whales joins another conservation announcement this week, which removed giant pandas from the endangered species list. (
  • Part of the delisting has to do with the fact that all humpback whales species were previously listed under one category on the endangered species lists, since first appearing on it in 1970. (
  • Nine of the 14 populations of humpback whale species, including those that winter in Hawaii, the West Indies, and Australia, no longer need Endangered Species Act protection, while the whales that breed off Mexico and feed off California, the Pacific Northwest, and Alaska will be listed as "threatened. (
  • Fishermen in Hawaii, who see the estimated 11,000 humpback whales that breed in Hawaii each winter and migrate to Alaska to feed during the summer, have been pushing for the whales to be removed from the endangered species list for years. (
  • To hear an example of one of their beautiful songs check out or read more about them at . (
  • The entire species of humpback whales had been listed as endangered under the Endangered Species Act since 1970. (
  • The move to divide the species into population segments and to delist some of them was spurred by a 2013 petition from the Hawaii Fishermen's Alliance for Conservation and Tradition to reclassify and delist the North Pacific humpback population, and a 2014 petition from the state of Alaska to reclassify the Central North Pacific population and remove it from ESA protection. (
  • Endangered Species Act protections for the West Australia, East Australia, West Indies, Hawaii, Brazil , Gabon/Southwest Africa, Southeast Africa/Madagascar, Oceania and Southeastern Pacific humpback populations have been removed. (
  • Some humpbacks are on the road to recovery, thanks to the tremendous power of the Endangered Species Act, but the job isn't finished. (
  • For the NMFS to imply that these whales have somehow met recovery is tragically misleading at best and makes a mockery of the Endangered Species Act. (
  • So why are these humpbacks saving species that they wouldn't even mingle with under other circumstances? (
  • One whale species that migrates to New England waters to feed is the humpback whale. (
  • Since the delisting of the Hawaii humpback whale population from the Endangered Species List in 2016, the sighting rates of humpbacks in the state and southeast Alaska have dropped, the Pacific Whale Foundation said earlier this week. (
  • The cost of migrating is a key parameter in determining a species' life history strategy and may provide insight into a potential shift in life history strategy that could contribute to an increased understanding of the recent trends," the whale foundation said. (
  • Since the humpbacks seem to be risking their own well being to save animals of completely different species, it's hard to deny that this behavior seems altruistic. (
  • The earliest reports of whale sightings in the Bay of Banderas, date back to 1858 and mention the presence of mainly 2 species: the Humpback and the Grey whale. (
  • Many species of whales were hunted from the mid 1800's to mid 1900's. (
  • Some biologists, organizations, eco-tour companies and their guides participate in the conservation of this species by taking pictures of the underside of Humpback whale flukes and send them to Astrid Frisch Jórdan who coordinates this catalog. (
  • Efforts are also made to collaborate with researchers working in other parts of the humpback whale's range around the world In coming years, the sanctuary plans to conduct research on other marine species and habitats including marine mammals, turtles, fish and corals. (
  • This whale was much larger than Orion so was most likely a female as the females are larger than the males in this species. (
  • The whale was dragging about 500 feet (152 meters) of gear and the thick line was "deeply embedded" in the whale's mouth, he said. (
  • It is thought that the single hair in each tubercle is used to detect temperature change in the water, the speed of the whale, and may even help to detect the presence of prey in the whale's "blind spots. (
  • A humpback whale's esophagus is "only about the size of maybe a big grapefruit or small melon," he said, meaning the chances of a sea lion that weighs hundreds of pounds getting swallowed and eaten are slim. (
  • Long-term, a humpback whale's chances of surviving in the East Alligator River are slim. (
  • If a croc bit a whale, their teeth would likely penetrate the whale's skin and thick blubber . (
  • With no other option available, and considering the whale's poor condition, the whale was humanely euthanized to prevent further suffering. (
  • While a Crittercam™ - a National Geographic Society video camera that gives a whale's-eye view-attached to a humpback provides additional insight into the whales' time at the seafloor, Ware cautions that there's plenty to learn about what the whales are doing in the deep. (
  • As the seal slipped down the whale's side, the humpback appeared to use its flippers to carefully help the seal back aboard. (
  • The humpback whale's behavior is most often playful and the show they perform for us at times can be quite spectacular. (
  • In this Wednesday, March 6, 2019 photo, provided by the NOAA Hawaiian Islands Humpback Whale National Marine Sanctuary, is an entangled subadult humpback whale that was freed of gear by a team of trained responders off Makena Beach, Hawaii. (
  • A trained team worked to untangle a humpback whale off the Washington coast on Aug. 8, 2019. (
  • A report from the society in 2019 said the humpback whale population off northeastern Vancouver Island had been increasing, most likely due to an abundance in prey in B.C. waters. (
  • Humpbacks feed only in summer, in polar waters, and migrate to tropical or sub-tropicalwaters to breed and give birth in the winter. (
  • North Atlantic Humpbacks breed in Caribbean waters, but travel north to the colder, fish-rich waters of the Arctic. (

  • The whale was spotted in the murky waters of the river today. (
  • This isn't the first time a humpback whale has taken a wrong turn and ended up in Kakadu waters. (
  • The last thing we want is a collision between a boat and whale in waters where crocodiles are prevalent and visibility underwater is zero," Parks Australia explained. (
  • Experts believe that humpbacks have migrated to tropical areas like Hawaii to avoid killer whale attacks because orcas avoid those waters. (
  • Hawaiian humpbacks feed in the cool waters around Alaska in the summer and then come to the warmer waters around Hawaii to mate and raise their young in the winter months. (
  • Swimming off the coast of Africa, humpback whales encounter more than warm waters for mating and bearing young, according to a new study led by the Wildlife Conservation Society (WCS). (
  • The research team's primary goal was to understand the migratory routes used by the whales from the breeding areas off western Africa to areas where the whales likely feed in Antarctic or sub-Antarctic waters. (
  • Several whales predictably remained in the offshore waters of Gabon or traveled south. (
  • During this critical refueling stage in these waters, the whales are more vulnerable to environmental stressors, such as those potentially created by increasing tourism and industrial development in the region. (
  • It said the whale had been sighted around Northeast Vancouver Island since 2004 but also in southeastern Alaska, the Salish Sea, the Central Coast and in the waters off southwestern Vancouver Island. (
  • Humpback whales are commonly found in coastal or shelf waters in high-latitude areas in summer, feeding in the cold, productive waters. (
  • The humpback whale feeds in colder waters during spring, summer and autumn, then migrates to winter ranges in tropical seas, where it calves and breeds. (
  • Vessels will continue to have to stay a specific distance away from humpback whales in Hawaii and Alaska waters. (
  • An estimated 11,000 humpback whales breed in Hawaii waters each winter and migrate to Alaska to feed during the summer, the fisheries service said. (
  • In addition to whales that breed in Hawaii and Mexico, Alaska also gets whales that spend the winter in waters around Okinawa and the Philippines. (
  • A couple hundred feet from his seat on a whale-watching boat, the waters of Monterey Bay in California teemed with activity. (
  • An interesting country with a rich history and very strong culture, Tonga is one of the few places in the world where it is possible to swim with the humpback whales that migrate to Tongan waters every year from their feeding grounds in the Antarctic. (
  • The humpback whales are present in Tongan waters from around mid-June to early October and can be seen all over Tonga, but the Vava'u group of islands in the north of the archipelago is by far the most popular area to see them. (
  • From May to August, the humpbacks relocate from cold Antarctic waters to the warmer Queensland climate, where pregnant females will give birth. (
  • And its shallow waters are no place for a whale the size of a bus. (
  • The whales are part of Australia's west coast humpback whale population, which each year travels from cold feeding waters off Antarctica to warm waters in the Kimberley to breed . (
  • Interactions between ships and whales are frequent in Glacier Bay and adjacent waters. (
  • Unintentional ship-whale encounters have increased over the past few decades as whale populations rebound from the large-scale commercial whaling in the 1950s and 1960s, and as the number and size of ships plying the world's waters have increased. (
  • Likewise, monitoring efforts in 1985 recorded 41 individual humpback whales using the waters in Glacier Bay and Icy Strait. (
  • Nevertheless the same encounters coveted by passengers could have adverse impacts on individual whales, and ultimately affect the population using the park and adjacent waters. (
  • Whales #1 and #2, the first photographed and cataloged in Irish waters 20 years ago, were spotted again after two decades. (
  • First cataloged humpback whales in Irish waters spotted together again two decades on. (
  • The Irish Whale and Dolphin group were treated to an exceptional surprise this week as the first two cataloged humpback whales in Irish waters were spotted once more, almost 20 years to the day since they were first photographed. (
  • Humpbacks spend their summer in the food-rich waters of the Antarctic or Arctic, and in the winter migrate to the tropics to breed and mate. (
  • The data tags showed that these quiet calls usually occurred while whales were swimming, suggesting they help mother and calf keep together in the murky waters of Exmouth Gulf. (
  • The findings will help conserve this important humpback habitat and - crucially - ensure these nursery waters are kept as quiet as possible. (
  • The number of humpback whales that use Hawaiian waters as their principle wintering ground is estimated to be more than 10,000 animals. (
  • From these sightings, the research team found that pods of whales that contained calves prefer shallower waters than pods without calves. (
  • The absolutely value of learning about this case is - know that there are humpbacks in the waters of British Columbia. (
  • This humpback whale is part of the Tongan tribe population, which migrates from feeding grounds in Antarctica, past New Zealand to breed in tropical waters around Tonga in the Pacific. (
  • VANCOUVER - Marine mammal rescue groups and federal fisheries officials are working against time in waters off the coast of British Columbia to save three humpback whales entangled in fishing gear. (
  • Thousands of humpback whales visit Hawaiian waters every year from November through May. (

  • Keep in mind, however, that mariners may also encounter humpback whales at the surface over deeper waters. (
  • Set in the spectacular waters of Alaska, Hawaii and the remote islands of Tonga, this ocean adventure offers audiences an up-close look at how these whales communicate, sing, feed, play and take care of their young. (
  • This is the start of whale season, when the gentle giants breed in the warm northern waters off Australia after feeding in Antarctica. (
  • But we know there are individual whales in the eastern Australian humpback population who bubble-net feed in Antarctic waters. (
  • This means the unique behaviour in Australian waters may have evolved independently, or through cultural transmission (learning new behaviours from different whales). (
  • Until then, humpback whale congregations this large had never been observed in Australian waters. (
  • The majority of the east Australian humpback whale population spends the summer months feeding in Antarctic waters . (
  • [12] , [13] quantified the meso-scale distribution pattern of whales in relation to krill biomass and patch structure in the continental shelf waters of the Antarctic Peninsula. (
  • The Hawaiian Islands Humpback Whale National Marine Sanctuary, which is jointly managed by the National Oceanic and Atmospheric Administration and the State of Hawai`i, lies within the shallow warm waters surrounding the main Hawaiian Islands and constitutes one of the world's most important humpback whale habitats and includes other significant habitats such as coral reefs. (
  • The Antarctic Humpback Whale Catalogue (AHWC) is an international collaborative project investigating movements of humpback whales in the Southern Ocean and corresponding lower latitude waters [ 20 ]. (
  • The National Marine Fisheries Service said it first had evidence to indicate there were 14 distinct populations of humpback whales around the world. (
  • WASHINGTON (CN) - Conservationists are concerned about the delisting of nine populations of humpback whales while the number of whale entanglements in fishing nets is on the rise. (
  • Whale sightings are becoming increasingly common in New York City, with 20 individual whales spotted in 2016 alone. (

  • According to the Globe , state environmental officials recently issued a "high risk" warning to boat operators after 10 right whales - five pairs of mothers and calves - were spotted in Cape Cod Bay. (
  • In a rare piece of good news for whales, humpbacks who live and breed in the southern oceans near Antarctica appear to be making a comeback, with females in recent years having a high pregnancy rate and giving birth to more calves. (
  • Whales arrive now almost one month earlier than 31 years ago, particularly groups without calves. (
  • Ecologists from Denmark and Australia used temporary tags on humpback mothers and their calves in Exmouth Gulf off western Australia to learn more about the first months of a humpback's life. (
  • According to lead author Simone Videsen of Aarhus University: "We know next to nothing about the early life stages of whales in the wild, but they are crucial for the calves' survival during the long migration to their feeding grounds. (
  • HONOLULU (KHON2) - Researchers at the University of Hawaii at Manoa Marine Mammal Research have video of humpback whale calves nursing in the Maui breeding grounds. (
  • They used suction-cup tags with cameras, acoustic recorders, depth sensors and accelerometers to follow seven humpback whale calves. (
  • Among humpback whales, mothers with calves are a particularly special group, especially in terms of conservation. (
  • Whale calves represent the next generation of an increasing population of humpback whales that will need our continued monitoring and stewardship. (
  • This not only includes their own humpback calves, but also sea lions, ocean sunfish, harbor seals and gray whale calves as well. (
  • Crude birth rate is an index of annual reproduction calculated by dividing the number of calves by the total whale count. (
  • Mature humpback whales are too large and too formidable to be hunted by orcas themselves, but their calves are vulnerable. (
  • Orcas have been witnessed hunting humpback whale calves in much the same way that they hunt gray whale calves. (
  • So, by proactively foiling orca hunts, perhaps the humpbacks are hoping to make them think twice about messing with their own calves. (
  • So far, climate change around the Antarctic Peninsula has been beneficial for humpbacks, he said, providing about 80 more ice-free days per year when these whales that prefer open water can feed on abundant stocks of tiny shrimplike crustaceans called krill. (
  • Very little information has been gathered on the feeding patterns of krill predators such as whales, seals and penguins in the Antarctic because of the area's harsh conditions. (
  • We're not even sure where these east Australian whales go in the Antarctic and it's very hard to get estimates of how much krill there is simply because it's such a difficult environment to work in. (
  • All baleen whales strain huge volumes of ocean water through their baleen plates to capture food: tons of krill, other zooplankton, crustaceans and small fish. (
  • Humpback whales in the Southern Ocean feed mainly on the Antarctic krill . (
  • This isn't the first time animals other than fish and krill have had the misfortune of accidentally ending up in the mouth of a humpback whale. (
  • Humpback whales are known for the complexity of their feeding techniques, which include "trapping" krill and other prey within bubble nets they produce and gulping up to two-thirds their weight in prey-laden water. (
  • Bubble-net feeding is when whales deliberately blow bubbles from their noses to encircle their food - krill and fish - like a net, concentrating their prey into a tight ball. (
  • Baleen whales consume between 1 and 8 tones (2000 and 9000 pounds) of fish and krill a day! (
  • Ecological relationships of krill and whales have not been explored in the Western Antarctic Peninsula (WAP), and have only rarely been studied elsewhere in the Southern Ocean. (
  • Tagged whales rested during daylight hours and fed intensively throughout the night as krill migrated toward the surface. (
  • At the same time, baleen whale populations in the Southern Ocean, which feed primarily on krill, are recovering from past exploitation. (
  • Consideration of these features and the effects of climate change on krill dynamics are critical to managing both krill harvests and the recovery of baleen whales in the Southern Ocean. (
  • A variety of predators, including penguins, seals, seabirds, and baleen whales rely heavily on Antarctic krill as a food resource. (
  • [11] found fin and humpback whales were associated with different age classes of krill in the South Shetland Islands in summer months. (
  • All previous studies indicate a tight linkage between the distribution of baleen whales and krill in this region. (
  • To date, however, no research has examined linkages between the distribution of krill and whales at the onset of winter in Antarctica. (
  • He noted a recent case where a young humpback whale approached the float of a longliner and entangled itself while playing with a nearby buoy. (

  • Other scientists have reported humpback whale mother-calf pods showing preferences for shallow, protected areas in regions such as Brazil, Madagascar, and the Dominican Republic, but our researchers were the first to conduct a long-term study across the Maui four-island region. (
  • This included adults and sub-adults as well as single individuals, mother-calf-escort groups and competitive male groups, the whale foundation said. (
  • Another event, involving a pair of humpback whales attempting to save a gray whale calf from a hunting pod of orcas after it had become separated from its mother, was captured by BBC filmmakers. (
  • That is a nice size flipper for the female whale to protectively hold above her calf who is a whopping twelve feet long when it is born. (
  • Past knowledge claimed that a humpback could only produce a calf every two or three years. (
  • Now scientists have seen an identified whale which had a new calf each year for several years, and nearly twenty percent of the other females in the studied group did also. (
  • NOAA's Ed Lyman, the sanctuary's whale entanglement coordinator, was part of the team that cut the gear away from the whale. (
  • There are are usually about 10 whale entanglement responses each year in Hawaii, Lyman said. (
  • They did exactly the right thing by keeping their distance and watching the whale so the team could quickly find it," said Kristin Wilkinson, regional coordinator of NOAA Fisheries' Pacific Northwest Large Whale Entanglement Response Network. (
  • To hear the full interview with Paul Cottrell, listen to the audio labelled: Whale Entanglement. (
  • Although commercial whaling seriously depleted all humpback stocks, and these whales are vulnerable to ship collisions, entanglement in fishing gear, and disturbance (even serious injury) from industrial noise, humpback whales have demonstrated remarkable resilience and many of the stocks are recovering. (
  • Whales are under threat in many areas from ship strikes, entanglement in fishing gear, habitat deterioration, declining prey and noise disturbance. (
  • These whales face several significant and growing threats, including entanglement in fishing gear, so ending protections now is a step in the wrong direction," Kristen Monsell, an attorney with the Center for Biological Diversity, said in a statement. (
  • The whales also face fishing gear entanglement threats. (
  • They have already rescued 27 humpbacks from entanglement. (
  • The whale was thin and there were no recent signs of entanglement, vessel strike or other major wounds. (
  • Because entanglement in fishing gear is a major risk to humpbacks, these findings have implications on bottom-set gear like those used in lobster traps. (
  • A key research program for the sanctuary focuses on the issue of humpback whale entanglement in marine debris and active fishing gear. (
  • However, researchers now find, thanks to devices that detect whale song, that these grounds extend throughout the Hawaiian archipelago into the northwestern Hawaiian Islands. (
  • A mystery for whale researchers has been where the whales feeding in the summer in the Bering Sea and in the Aleutians off Alaska went in the winter to breed - many just didn't show up in the known wintering grounds," said researcher Marc Lammers, a marine biologist at the University of Hawaii. (
  • The researchers are now analyzing the structures of the whale songs from the northwestern and main Hawaiian Islands to see if the humpbacks in this new area are an extension of the existing population or a separate breeding stock altogether. (
  • As the researchers took their surveys, the whales were often just as curious about the team as it was about them. (
  • Whale researchers are concerned that this moment of health and easy access to food will be short-lived. (
  • To uncover the behavior, researchers attached sensors to 52 humpback whales in the Gulf of Maine, off the U.S. Northeast coast. (
  • Humpback whales have a type of brain cell seen only in humans, the great apes, and other cetaceans such as dolphins, US researchers reported on Monday. (
  • The finding may help explain some of the behaviors seen in whales, such as intricate communication skills, the formation of alliances, cooperation, cultural transmission and tool usage, the researchers report in The Anatomical Record. (
  • Complex social patterns The researches found spindle neurons in the same location in toothed whales with the largest brains, which the researchers said suggests that they may be related to brain size. (
  • In November, a team of U.S. and international researchers, wildlife managers and federal officials met in Honolulu to discuss a decline in sightings of humpback whales in Hawaii. (
  • The researchers used satellite tags affixed to more than a dozen whales to quantify the amount of overlap between hydrocarbon exploration and extraction, environmental toxicants, shipping lanes, and humpback whales occurring in their near-shore breeding areas. (
  • The researchers also tried to understand the overlap between whale movements and human intrusions such as oil platforms and shipping lanes. (
  • Whale researchers on Vancouver Island say a humpback known as Kayak was found dead on a beach on Haida Gwaii Saturday. (
  • The fieldwork also consisted of flying drones over the tagged whales, allowing researchers to calculate their overall length, body condition and health. (
  • It was originally reported as dead, but the next day, bird researchers based on Monomoy Island were able to locate the whale and discovered it was still alive. (
  • By affixing DTAGs - synchronous motion and acoustic recording tags - to the whales' backs via four suction cups, the researchers could track for the first time the movements of the whales below the ocean's surface. (
  • In January, Ultimate Whale Watch on Maui hosted researchers for 10 days on its vessel. (
  • The researchers completed 243 drone flights within the Hawaiian Islands Humpback Whale National Marine Sanctuary over 17 days with 150 humpback whales measured per month. (
  • Join a team of researchers as they unlock the secrets of the humpback and find out why humpbacks are the most acrobatic of all whales, why they sing their haunting songs, and why these intelligent, 55-foot, 50-ton animals migrate up to 10,000 miles round-trip every year. (

  • Every winter, about 10,000 humpback whales migrate to Hawaii, with the main purpose of breeding. (
  • During mating season, humpback whales found feeding on the BC coast migrate to their breeding "grounds" in Hawaii and Mexico. (
  • Two of the whales traveled an astonishing 5,000-mile migration from near the equator to the edge of the sub-Antarctic ice shelf around Bouvet Island. (
  • Dr Noad said there was once thought to be a healthy population of around 30,000, but after shore-based whaling in the 1950s and massive illegal Soviet whaling in the Antarctic in the early 1960s, just a few hundred were left. (
  • Each winter, the humpback whales visit Tonga in a cycle of life characterized by a remarkable annual migration north from their feeding grounds in the Antarctic to the 170-plus islands of the Tongan archipelago where they breed and give birth. (
  • Southern Humpbacks feed in the Antarctic in preparation for their lengthy northern migration when they abstain from feeding. (
  • Thankfully, a ban on all commercial whaling took effect in 1966 due to the growing public and scientific concern. (
  • This is migrating season for humpback whales. (
  • It looks like another early season for humpback whales in the Santa Barbara Channel. (
  • In general, whales are large, streamlined aquatic mammals with eyes, a mouth, a blowhole and two flippers and a tail that are used for swimming. (
  • The length of the flippers and the tubercles on their front edges distinguish the humpback from other whales. (
  • Ocean users are also subject to safety risks when whales surface, breach, or slap their massive tails or flippers. (
  • The humpback whale, while a more bulky shape that other baleen whales, is very agile and loves to leap out of the water and fling those long flippers out wide - almost as though they were going to fly away. (
  • From 2013 - 2017, naturalists used the app to record location and group information about humpback whales they encountered. (
  • In September 2017, one humpback whale was found washed up on the shore by the Mohegan Bluffs. (

  • This study demonstrates clearly that all of the countries on the west coast of Africa need to work together on a range-wide humpback whale conservation strategy and consider the possibility of creating a whale sanctuary," said Professor Lee White, CBE, director of Gabon's National Parks Agency. (
  • This technology allows the science and conservation communities to discover detailed seasonal migration routes, timing and destinations, so we can characterize these important habitats and reduce potential impacts of human activities, even in the harshest possible marine environments," said Dr. Bruce Mate , who pioneered the satellite-monitored radio tagging of large whales. (
  • So we thought this is a success in ocean management and we wanted to point that out to the world - that things are good with whales in Hawaii," said Phil Fernandez, president of the Hawaii Fishermen's Alliance for Conservation and Tradition. (
  • Wildlife officer Geoff Ross, from New South Wales National Parks and Wildlife Service, said better conservation practices have helped the humpback population bounce back in recent years. (
  • He said increased humpback breeding is linked to better conservation measures. (
  • Yet we've been repeating the "save the whales" mantra for so long that the real conservation status of most whales is widely misunderstood. (
  • Conservation efforts worked, and humpback whales are doing all right now. (
  • For many of these passengers, seeing whales may be a once-in-a-lifetime event, which undoubtedly invokes a keener appreciation for conservation and natural history, clearly consistent with the NPS mandate. (
  • While humpback whales and giant pandas still face threats in the wild, they have proven that conservation and protection work in stabilizing a population. (
  • Separately managing humpback whale populations that are largely independent of each other allows us to tailor conservation approaches for each population. (
  • The Humpback is a baleen whale, so that instead of teeth, it has long plates which hang in a row (like the teeth of a comb) from its upper jaws. (
  • The humpback is a type of whale called a baleen whale. (
  • Four days later, a dead humpback whale was discovered bloated and floating near the area where the encounter occurred. (
  • DRONE footage has captured 70 huge tiger sharks devouring a dead humpback whale in Shark Bay on the Western Australian coastline. (

  • A humpback whale with a scar on its side, maybe incurred from this newly-observed feeding behavior. (
  • In the case of the whales, this takes the form of a previously unknown behavior, in which the animals repeatedly rotate their bodies and gulp fish just off the seafloor, sometimes making contact with the ocean bottom itself and creating scars on their bodies. (
  • The sensors record the endangered animals' location, speed and body orientation, and showed that 40 percent of them whales engaged in this never-before-observed behavior. (
  • Humpback whales reach nearly 50 feet in length and are characterized by their long pectoral fins, acrobatic behavior, and haunting songs. (
  • The accelerometer data allows them to quantify the fine-scale behavior, movement and breathing patterns of tagged whales. (
  • It's not unreasonable to think that humpbacks are demonstrating altruistic behavior, especially considering their sophisticated thinking and communication. (
  • Not only did the data show that these humpbacks, "by far the most acrobatic of all baleen whales ," Ware says, were performing bottom side-rolls and seafloor scooping, it indicates that this bottom feeding does not include lunging, previously assumed to be the humpbacks' primary feeding behavior. (
  • Tag data showed that the bottom-feeding humpbacks were moving at too low a speed to characterize this behavior as lunge feeding. (
  • an inherent feature of humpback whale behavior. (
  • Even if it has more to do with revenge than altruism, though, the behavior would represent evidence of an intense and complicated emotional life among humpbacks that is unprecedented in the animal world, outside of primates. (
  • Toothed whales such as orcas are generally considered more intelligent than baleen whales such as humpbacks and blue whales, which filter water for their food. (
  • Hundreds of common dolphins, one gray whale and six orcas have also been spotted from Island Packers boats in the last few days, said Connally. (
  • The orcas were able to successfully knock the seal off the ice, and just as they were closing in for the kill, a magnificent humpback whale suddenly rose up out of the water beneath the seal. (
  • He began collecting accounts of humpback whales interacting with orcas, and found nothing short of 115 documented interactions, reported by 54 different observers between 1951 and 2012. (
  • It seems clear from the data that the humpback whales are choosing to interact with the orcas specifically to interrupt their hunts. (
  • Every year, the most acrobatic of all whales, the Humpback, visits the Bay of Banderas in order to reproduce and give birth. (
  • Due to over-hunting, its population fell by an estimated 90% before a whaling moratorium was introduced in 1966. (

  • Scientists are concerned whale numbers will be overstretched in the next few years. (
  • Scientists predict there will be more shark nets entanglements and strandings if whale populations continue unchecked. (
  • Scientists believed more than 60,000 humpbacks are out there, up from less than 5,000 in the 1960s. (
  • There are about 3,200 of the whales in this group, which is only about half of what scientists previously thought, Nammack said. (

  • Scientists are hoping to take poo samples from the whale in Van Diemen Gulf, and could also collect whale snot to learn more about its health. (
  • Now, scientists have confirmed that humpback whales in the southern Gulf of Maine are spending more feeding time on the ocean floor than in any of these other feeding behaviors. (
  • The tag data confirms the bottom-feeding that scientists had suspected from visible scarring along some whales' jaws. (
  • We saw about a dozen Blue Whales and Dozens of Humpbacks. (
  • It may have been easier for the humpbacks to recover than the bigger fin and blue whales because the humpbacks mature faster,have a short period between pregnancies, and have centralized breeding grounds. (
  • Fin and blue whales mate in the open ocean, making it harder for them to find a match, he said. (
  • He said he had also seen a smaller but obvious rebound among fin and blue whales - the planet's largest animals - as well as the Southern right whale, a cousin to the highly endangered Northern Right Whale . (
  • Blue whales are the largest whales. (
  • Saturday's kayakers, who are tourists from the United Kingdom, were paddling through a large pod of humpback whales when they were knocked underwater. (

  • Among the animals that have been observed being rescued by humpback whales were California sea lions, ocean sunfish, harbor seals, and gray whales. (
  • as the whale undertakes a deep dive it usually arches its back (hence the common name) so that the tail flukes are raised above the water and clearly visible. (
  • When a humpback dives deeply, it will frequently lift the flukes straight out of the water in a fluke -up dive, revealing the coloration and marking/scar pattern on the ventral surface. (
  • Orion was in a travelling pattern so while he was spending lots of time on the surface we weren't seeing many views of his tail flukes so we headed over to an area where another Humpback whale had been spotted. (

  • In this case, my bet would be on the whale - if it was in relatively good condition and could swim well. (
  • Then, the whale or group of whales swim together from beneath, rise to the surface opening their mouths, and gulp up their prey. (
  • To do this, the whale starts below the surface, weaving a net of bubbles by forcing air out through their blowholes as they swim upwards in a tight spiral, finally surfacing open-mouthed right amongst the food. (
