Structural dynamics of ligand diffusion in the protein matrix: A study on a new myoglobin mutant Y(B10) Q(E7) R(E10). (1/602)

A triple mutant of sperm whale myoglobin (Mb) [Leu(B10) --> Tyr, His(E7) --> Gln, and Thr(E10) --> Arg, called Mb-YQR], investigated by stopped-flow, laser photolysis, crystallography, and molecular dynamics (MD) simulations, proved to be quite unusual. Rebinding of photodissociated NO, O2, and CO from within the protein (in a "geminate" mode) allows us to reach general conclusions about dynamics and cavities in proteins. The 3D structure of oxy Mb-YQR shows that bound O2 makes two H-bonds with Tyr(B10)29 and Gln(E7)64; on deoxygenation, these two residues move toward the space occupied by O2. The bimolecular rate constant for NO binding is the same as for wild-type, but those for CO and O2 binding are reduced 10-fold. While there is no geminate recombination with O2 and CO, geminate rebinding of NO displays an unusually large and very slow component, which is pretty much abolished in the presence of xenon. These results and MD simulations suggest that the ligand migrates in the protein matrix to a major "secondary site," located beneath Tyr(B10)29 and accessible via the motion of Ile(G8)107; this site is different from the "primary site" identified by others who investigated the photolyzed state of wild-type Mb by crystallography. Our hypothesis may rationalize the O2 binding properties of Mb-YQR, and more generally to propose a mechanism of control of ligand binding and dissociation in hemeproteins based on the dynamics of side chains that may (or may not) allow access to and direct temporary sequestration of the dissociated ligand in a docking site within the protein. This interpretation suggests that very fast (picosecond) fluctuations of amino acid side chains may play a crucial role in controlling O2 delivery to tissue at a rate compatible with physiology.  (+info)

Declining survival probability threatens the North Atlantic right whale. (2/602)

The North Atlantic northern right whale (Eubalaena glacialis) is considered the most endangered large whale species. Its population has recovered only slowly since the cessation of commercial whaling and numbers about 300 individuals. We applied mark-recapture statistics to a catalog of photographically identified individuals to obtain the first statistically rigorous estimates of survival probability for this population. Crude survival decreased from about 0.99 per year in 1980 to about 0.94 in 1994. We combined this survival trend with a reported decrease in reproductive rate into a branching process model to compute population growth rate and extinction probability. Population growth rate declined from about 1. 053 in 1980 to about 0.976 in 1994. Under current conditions the population is doomed to extinction; an upper bound on the expected time to extinction is 191 years. The most effective way to improve the prospects of the population is to reduce mortality. The right whale is at risk from entanglement in fishing gear and from collisions with ships. Reducing this human-caused mortality is essential to the viability of this population.  (+info)

Sex-biased dispersal in sperm whales: contrasting mitochondrial and nuclear genetic structure of global populations. (3/602)

The social organization of most mammals is characterized by female philopatry and male dispersal. Such sex-biased dispersal can cause the genetic structure of populations to differ between the maternally inherited mitochondrial DNA (mtDNA) and the bi-parental nuclear genome. Here we report on the global genetic structure of oceanic populations of the sperm whale, one of the most widely distributed mammalian species. Groups of females and juveniles are mainly found at low latitudes, while males reach polar waters, returning to tropical and subtropical waters to breed. In comparisons between oceans, we did not find significant heterogeneity in allele frequencies of microsatellite loci (exact test; p = 0.23). Estimates of GST = 0.001 and RST = 0.005 also indicated negligible if any nuclear DNA differentiation. We have previously reported significant differentiation between oceans in mtDNA sequences. These contrasting patterns suggest that interoceanic movements have been more prevalent among males than among females, consistent with observations of females being the philopatric sex and having a more limited latitudinal distribution than males. Consequently, the typical mammalian dispersal pattern may have operated on a global scale in sperm whales.  (+info)

Quench-flow experiments combined with mass spectrometry show apomyoglobin folds through and obligatory intermediate. (4/602)

Folding of apomyoglobin is characterized by formation of a compact intermediate that contains substantial helicity. To determine whether this intermediate is obligatory or whether the protein can fold directly into the native state via an alternate parallel pathway, we have combined quench-flow hydrogen-exchange pulse labeling techniques with electrospray ionization mass spectrometry. The mass spectra of apomyoglobin obtained at various refolding times suggest that apomyoglobin indeed folds through a single pathway containing an obligatory intermediate with a significant hydrogen-bonded secondary structure content.  (+info)

Purification and properties of whale thyroid-stimulating hormone III. Properties of isolated multiple components. (5/602)

Properties of the four purified components of whale thyroid-stimulating hormone (TSH) have been compared. The amino acid composition shows close similarity among these components. Their hexosamine and sialic acid contents are of the same magnitude, whereas the neutral sugar composition differs somewhat from each other. The molecular weight of whale TSH determined by sedimentation equilibrium is 29,000, and no difference in molecular weight as well as in Stokes radius as determined by gel filtration has been detected among these four components. The amino acid and carbohydrate compositions of whale TSH resemble those of TSH from other species, especially those of non-primate mammalian TSH. Whale TSH contains, unlike bovine TSH but like human TSH, 1-2 residues of sialic acid as a constituent carbohydrate.  (+info)

Abiotrophia balaenopterae sp. nov., isolated from the minke whale (Balaenoptera acutorostrata). (6/602)

Phenotypic and phylogenetic studies were performed on a hitherto undescribed micro-organism isolated from a minke whale (Balaenoptera acutorostrata). Comparative 16S rRNA gene sequencing studies demonstrated that the unknown strain constituted a new subline close to, but distinct from, Abiotrophia adiacens and Abiotrophia elegans. The unknown bacterium was readily distinguished from these two Abiotrophia species by biochemical tests and electrophoretic analysis of whole-cell proteins. On the basis of phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Abiotrophia balaenopterae sp. nov., the type strain of which is M1975/96/1T (= CCUG 37380T).  (+info)

Immunohistological distributions of fibronectin, tenascin, type I, III and IV collagens, and laminin during tooth development and degeneration in fetuses of minke whale, Balaenoptera acutorostrata. (7/602)

The immunohistological distributions of fibronectin, tenascin, type I, III and IV collagens, and laminin were observed in the tooth buds of fetuses of minke whale, Balaenoptera acutorostrata. Distributions of extracellular matrices (ECMs) examined in this study except for tenascin were generally similar to those of terrestrial mammalian species during development of the tooth bud. Tenascin in the fetuses of minke whale showed characteristic distributions in the dental lamina and the enamel organ in the early tooth developmental stage. In the physiological degeneration stage of tooth bud development, immunoreactivity of the ECMs were very weakly and limitedly detected in the dental papilla and the surrounding mesenchyme. Immunoreactivity of tenascin and type I and III collagens were positively detected in the developing baleen plate germ which was associated with the degenerating tooth bud. These findings suggested that expressions of the ECMs were related to the formation of the tooth bud and baleen plate germ, and that the lack of the ECMs was related to the degeneration of the tooth bud in the fetal minke whale.  (+info)

A study of vibrational relaxation of B-state carbon monoxide in the heme pocket of photolyzed carboxymyoglobin. (8/602)

The vibrational energy relaxation of dissociated carbon monoxide in the heme pocket of sperm whale myoglobin has been studied using equilibrium molecular dynamics simulation and normal mode analysis methods. Molecular dynamics trajectories of solvated myoglobin were run at 300 K for both the delta- and epsilon-tautomers of the distal histidine, His64. Vibrational population relaxation times were estimated using the Landau-Teller model. For carbon monoxide (CO) in the myoglobin epsilon-tautomer, for a frequency of omega0 = 2131 cm-1 corresponding to the B1 state, T1epsilon(B1) = 640 +/- 185 ps, and for a frequency of omega0 = 2119 cm-1 corresponding to the B2 state, T1epsilon(B2) = 590 +/- 175 ps. Although the CO relaxation rates in both the epsilon- and delta-tautomers are similar in magnitude, the simulations predict that the vibrational relaxation of the CO is faster in the delta-tautomer. For CO in the myoglobin delta-tautomer, it was found that the relaxation times were identical within error for the two CO substate frequencies, T1delta(B1) = 335 +/- 115 ps and T1delta(B2) = 330 +/- 145 ps. These simulation results are in reasonable agreement with experimental results of Anfinrud and coworkers (unpublished results). Normal mode calculations were used to identify the dominant coupling between the protein and CO molecules. The calculations suggest that the residues of the myoglobin pocket, acting as a first solvation shell to the CO molecule, contribute the primary "doorway" modes in the vibrational relaxation of the oscillator.  (+info)

The North Atlantic right whale (Eubalaena glacialis) is a large (up to 17 m) whale, generally black in colour with occasional white belly patches and no dorsal fin. Right whales were once common in temperate waters of the Western Atlantic but were seriously depleted by whaling. An accurate population estimate for the species is yet to be calculated. The population of North Atlantic right whales in Atlantic Canadian waters was estimated in 2003 to number about 322 animals; however more recent estimates suggest the current population numbers about 350 animals. North Atlantic right whales are protected and listed under Schedule 1, Part 2 of the Species at Risk Act (SARA).
In a new study published this week in Endangered Species Research, North Atlantic right whale scientists found that whales who undergo prolonged entanglements in fishing gear endure sky-high hormone levels, indicating severe stress, which researchers discovered using a pioneering technique of examining scat from live, entangled, and dead whales over 15 years.
The tiny population of critically-endangered North Atlantic right whales may not have had any calves this year, scientists fear, in what would be an “unprecedented” calamity for the species.
A new study offers a glimpse into the state of mind of North Atlantic right whales while they are trapped and dying in fishing gear.
Whales are separated into the toothed whales, Odontocetes (which includes dolphins, porpoises, narwhals, beaked whales and sperm whales), and the whalebone, or baleen, whales, also called Mysticetes. The latter are mostly very large, which, instead of teeth, have baleen (whalebone) to filter small prey from the water; they are what people generally think of when the word whale is used. The whalebone whales include the rorquals - the blue whale, fin whale, sei whale, Brydes whale, minke whale, and humpback whale; the Grey Whale; and the various right whales. Although whales are famed for the massive size reached by some species, such as the blue whale (the largest animal to ever live), others are relatively small, like the pygmy right whale which grows to about 20 feet[1]. Though whales have many traits in common with fish (including fins and tails) they are classified as mammals under the Linnaean taxonomy classification system because they breathe air and lactate. Whales have a number of ...

Since the decimation of the southern right whale Eubalaena australis population in New Zealand by whaling, research on its recovery has focused on the wintering ground at the Auckland Islands, neglecting potentially important wintering habitat at Campbell Island. For the first time in 20 years we conducted an expedition to sub-Antarctic Campbell Island to document and describe E. australis occupying this wintering habitat. We used a variety of methods including photo-identification, genetic and stable isotope analyses of tissue samples, and visual surveys of abundance and distribution, to provide details on the demography, population connectivity and ecology of E. australis wintering at Campbell Island. Our primary findings include (1) a lack of calves observed at Campbell Island, (2) an age-class bias toward sub-adults encountered at Campbell Island, (3) nine photo-identification matches between individuals observed at Campbell Island and previously documented elsewhere in New Zealand, (4) no ...
ABSTRACT: The location of mating grounds used by Endangered North Atlantic right whales Eubalaena glacialis has eluded discovery despite centuries of whaling and decades of marine mammal surveys. If this species gestation duration is similar to the closely related southern right whale E. australis, then conception for the North Atlantic right whale occurs in the boreal winter. Between 2002 and 2008, aerial surveys identified half the North Atlantic population in the central Gulf of Maine between November and January. Generalized linear models indicated that significantly higher proportions of both known fathers and conceptive females were present in this region compared to most other areas seasonally inhabited by right whales. Their presence in the central Gulf of Maine during the estimated conception period strongly suggests that this region is a mating ground for the species. Roseway Basin, on the southwestern Scotian Shelf, also had high proportions of reproductive whales and may be the site ...

There are two types of whale: baleen and toothed.. Baleen whales have long bristle-fringed plates, known as baleen, which are made of keratin (a protein also found in human hair and fingernails) and fixed to the roof of the mouth. These sieve the minute crustaceans, such as krill, that they feed on. Baleen whales have two blowholes. And unlike some other whales, they do not use echolocation (emitting sounds to locate solid objects).. Baleen whales include the largest animals ever known. Greatest of all is the blue whale; the heaviest ever recorded was a female of 190 tonnes. Baleen whales migrate through New Zealand waters on their way south to feed on krill, which are abundant in the Southern Ocean. Of the worlds 13 species of baleen whales, eight are known in New Zealand, but only two, the southern right whale and Brydes whale, breed in New Zealand waters.. ...
Perrins beaked whale (Mesoplodon perrini) is the newest species of beaked whale to be described. The first two specimens were found in May 1975 stranded on the California coast, with two more specimens being found in 1978 and 1979, and the last in September 1997. They were initially identified as Hectors beaked whale (Mesoplodon hectori), except for the most recent one, which was assumed to be a neonate Cuviers beaked whale. Following inclusion of one of these specimens in a mtDNA sequence database of beaked whales, it turned out that they seemed well distinct from M. hectori (Dalebout et al. 1998). The other Hectors specimens from California were subsequently confirmed to belong to the same undescribed taxon (Dalebout 2002). The new species was formally described in 2002 by Dalebout et al.; its common and specific names are a tribute to cetologist William F. Perrin. Despite the superficial similarities to the (entirely allopatric) Hectors beaked whale, this species is closely related to ...
Since the work of Tower in the 1950s, we have come to expect lower neuron density in the cerebral cortex of larger brains. We studied dolphin brains varying from 783 to 6215g. As expected, average neuron density in four areas of cortex decreased from the smallest to the largest brain. Despite having a lower neuron density than smaller dolphins, the killer whale has more gray matter and more cortical neurons than any mammal, including humans. To begin a study of non-dolphin toothed whales, we measured a 596g brain of a pygmy sperm whale and a 2004g brain of a Cuviers beaked whale. We compared neuron density of Nissl stained cortex of these two brains with those of the dolphins. Non-dolphin brains had lower neuron densities compared to all of the dolphins, even the 6215g brain. The beaked whale and pygmy sperm whale we studied dive deeper and for much longer periods than the dolphins. For example, the beaked whale may dive for more than an hour, and the pygmy sperm whale more than a half hour. In ...
A collaborative Russia-U.S. research program on western gray whales (Eschrichtius robustus) summering off northeastern Sakhalin Island, Russia, has been ongoing since 1995 and has produced important new information on the present day conservation status of this critically endangered population. This interim report reviews preliminary findings from 2007 research activities and combines such with data from previous years, in some cases ranging back to 1994. Photo-identification research conducted off Sakhalin Island in 2007 resulted in the identification of 83 whales, including nine calves and two previously unidentified non-calves. When combined with data from 1994-2006, a catalog of 169 photo-identified individuals has been compiled. Not all of these 169 whales can be assumed to be alive, however. The most current mark-recapture analyses conducted estimated the abundance for the population to be 98 (95% CI=89-110) in 2002 and 99 (95% CI = 90-109) in 2003.

Lampreys are an amazing group of ancient fish species which first appeared around 360 million years ago. This means they evolved millions of years before the dinosaurs roamed the earth. There are about 39 species of lamprey currently described plus some additional landlocked populations and varieties. In general, lamprey are one of three different life history types and are a combination of non-parasitic and parasitic species. Non-parasitic lamprey feed on organic material and detritus in the water column. Parasitic lamprey attach to other fish species to feed on their blood and tissues. This is why lamprey are often unfairly called aquatic vampires.. Most, 22 of the 39 species, are non-parasitic and spend their entire lives in freshwater. The remainder are either parasitic spending their whole life in freshwater or, parasitic and anadromous. Anadromous parasitic lampreys grow in freshwater before migrating to the sea where they feed parasitically and then migrate back to freshwater to spawn. ...
American photographer Brian Skerry rates this meeting with a southern right whale in New Zealand waters as the most incredible animal encounter of his life. Skerry photographed the bus-sized whale - 14m long and 70 tonnes - investigating his dive assistant after the men had hitched a ride with a New Zealand research expedition to the Auckland Islands, aboard the Dunedin-based yacht Evohe. This photograph won the Underwater World category of this years Wildlife Photographer of the Year awards, the New Zealand Herald noted recently. The expedition leader, Dunedin marine biologist Dr Simon Childerhouse, said that expanding southern right whale numbers at the Auckland Islands were increasing the likelihood of Dunedin and Otago people having their own close encounters. Mating activity involving four of the whales off Taieri Mouth had been photographed by the Otago Daily Times in June last year, and the whales could be seen in the Otago Harbour.

Protecting right whale mothers and their young is critical to the recovery of the population, said Barb Zoodsma, NOAA Fisheries Service right whale biologist. The loss of any right whale is of concern, and we ask for everyone to adhere to measures that protect this critically endangered species.. Each year, pregnant females migrate southward more than 1,000 miles from feeding areas off Canada and New England to the warm, calm, coastal waters off South Carolina, Georgia and northeastern Florida to give birth and nurse their young. These waters are the only known calving area for the species.. Collisions with ships and entanglement in fixed fishing gear are the two greatest threats to the recovery of North Atlantic right whales, which is why it is important that all mariners and fishers are aware of the regulations. ...

Alfred the fossil whale skull: Photo credit: Ben Healley.. Monash University scientists have played a key role in discovering the origin of filter feeding in baleen whales - the largest animal known to have ever existed.. The discovery is detailed in a paper co-written with international researchers and palaeontologists from Museum Victoria. Alfred the 25- million-year-old fossilised whale skull was unveiled at the Museum today.. Alfred shows how ancient baleen whales made the evolutionary switch from biting prey with teeth to filtering using baleen, said Monash Science Senior Research Fellow, Dr Alistair Evans, one of the authors of the paper.. They first became suction feeders. Feeding in this way resulted in reduced need for teeth, so over time their teeth were lost before baleen appeared.. There has been a lot of mystery around how and when baleen first formed.. But we now have long-sought evidence of how whales evolved from having teeth to hair-like baleen - triggering the rise of ...
A new study of more than 100 North Atlantic right whales over 15 years shows the analysis of a hormone product in the animals waste can provide information on their stress levels and health.. (From Boston Globe/ By Ben Thompson) - These levels show stress from extreme physical trauma, lead study author Rosalind Rolland, a senior scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium, said in a statement.. Its an animal welfare issue, she said. For the first time, we can get hormone levels on not just dead but living whales.. The study, published this week in Endangered Species Research, covers the pioneering technique developed by Rolland used to examine feces taken from 125 right whales from 1999 to 2014. That group included a mix of 113 healthy whales, six that were chronically entangled in fishing gear, one that stranded for several days, and five that were quickly killed by vessel strikes, the aquarium said.. ...
Its always difficult to write the weekend whale watch report because theres just so much to say! Both Friday and Saturdays Breakfast with the Whales cruises were dominated by calves. On Friday, we watched as Baby tail lobbed, pec slapped and breached. Then we got to see Mom breach, followed by baby making another attempt. On Saturday, we spend most of our time with a very active and curious little calf. We saw 21 whales both days. On the 10:00 Whale Watch on Friday we saw 10 Whales of which 2 groups were competitive pods, and we even saw a few dolphins. On Saturday, guests aboard our 10:00 Whale Watch saw 15 whales in pods of twos and threes. The most exciting part of that trip was getting to witness MULTIPLE BREACHES! We saw 10 full-on breaches from the same pod of 3 whales. Our 3:00 Whales and Cocktails on both Friday and Saturday were a little quieter than the early trips. On Friday, we saw 6 whales and watched a competitive pod of 4 whales for most of the trip. On Saturday, we didnt see ...
Youll visit Stellwagen Bank, the East Coasts most famous whale watching destination. Stellwagens heavy concentration of humpback, finback, and minke whales guarantees an adventure filled with opportunities to view and learn about whales as they frolic in their natural habitat.. Each Boston Whale Watching Cruise is narrated and guided by a naturalist from the noted Whale Center of New England (WCNE). The WCNE has been studying the whales of New England for more than 20 years and its members are recognized worldwide as authorities on whales.. One of the whales youre likely to spot during a Boston Whale Watching Cruise is the humpback. These Northern hemisphere humpbacks reach an average length of 50 feet, and a weight of about 37 tons! Sadly, theyre also among the most endangered, and its estimated that only 8 percent of their original population remains. With the data collected on each cruise, WCNE is able to further the understanding of whales and their world. And, their presence on board ...
The southern right whale dolphin is a an underwater mammal that can be found in the cool waters of the southern hemisphere. This animal was first published in
With a body length of 10 m and an estimated mass of 9800 kg (Lockyer, 1981), the whale tagged with tag IV probably contained some 2001 of air after inhalation while at the surface (inferred from Clarke, 1978). If the lungs of a sperm whale collapse (Ridgway, 1971) as they do in smaller odontocetes (Ridgway et al., 1969), the whale would have had, at most, 3.51 of air available to it for sound production at a depth of 600 m. Thus, sperm whales recycle the air after each click or group of clicks (as demonstrated in Tursiops sp.; Dormer, 1979) and/or use very small volumes of air to generate each click. Considering the highly reduced air volume available for sound production when the whale is at a depth of 700 m and that sperm whales have been reported to phonate at depths of more than 2000 m (Whitney, 1968), it is conceivable that air simply is not involved in sperm whale sound production. That view, however, is not supported by experimental data on sound production in the homologous structures of ...
Because of where they live (and unlike many animals), whales are conscious breathers: they decide when to breathe. Whales breathe through blowholes. Baleen whales have two and toothed whales have one. These are on the top of the head: the animal breathes while most of their body is underwater. Breathing first shoots out extra water from the blowhole, making a jet into the air, followed by inhaling air into the lungs. All mammals sleep, including whales, but they cannot stay in an unconscious state for too long, because they need to be conscious to breathe. It is thought that only one hemisphere (half) of their brains sleeps at a time, so that whales are never completely asleep, but still get the rest they need.[9] Whales are thought to sleep around eight hours a day. A baby whale is called a calf. One calf is born every two or three years. Gestation takes up to a year. Nursing continues for more than a year in many species; there is a strong bond between mother and calf. Reproductive maturity ...

A major conservation concern for beaked whales (family Ziphiidae) is they appear to be vulnerable to modern sonar operations, which arises from recent strandings that temporally and physically coincide with naval sonar exercises.[20] Post mortem examinations of the stranded whales in concurrence with naval exercises have reported the presence of hemorrhaging near the ears or gas and fat emboli, which could have a deleterious impact on beaked whales that is analogous to decompression sickness in humans.[11] Gas and fat emboli have been shown to cause nervous and cardiovascular system dysfunction, respiratory distress, pain, and disorientation in both humans and animals.[20] In the inner ear, gas embolism can cause hemorrhages, leading to disorientation or vestibular dysfunction. Breath-holding divers, like beaked whales, can develop decompression-related problems (the bends) when they return to the surface after deep dives.[1] This is a possible hypothesis for the mass strandings of pelagic ...

Identified as Mystacodon selenensis, the fossil whale is described as a small to medium-sized creature that had teeth, but in other ways resembled modern humpbacks and blue whales, they explained - hence its name, which Science News said translates to toothed mysticete.. The remains were discovered in the deserts of Peru by a team led by Royal Belgian Institute of Natural Sciences paleontologist Olivier Lambert. It was approximately four meters long, or about as big as a modern-day pilot whale, and like primitive whales, still had a protruding hip bone indicating that it still had hind legs left over from when its ancestors were terrestrial quadrupeds.. However, the creature also had a flat snout similar to those of modern-day baleen whales, and while ancient whales had elbow-like joints in its front flippers, M. selenensis does not - nor do modern-day baleen whales, according to the authors of the new Current Biology paper.. Lamberts team believes that M. selenensis might have used ...

The Valley of Whales (Photo: Egypts Ministry of Environment Official Facebook page) In Egypts Valley of Whales-Wadi al-Hitan-the fossils of giant, ancient whales have sat for millions of years; they were first discovered by scientists in 1902. Since then, there have been 10 fossilized whales found in the area, according to the Cairo Post. But on Tuesday, Egypts Minister of Environment announced that a new fossil had been found-a 60-foot-long basilosaurus, a type of early whale, complete down to the relatively tiny vertebrae of the tail, thats estimated to be 40 million years old.. The fossil was uncovered by an Egyptian research team, and, along with the fossil, they found the remains of crabs and sawfish inside the whale, along with smaller whale. (Its not clear whether the smaller whale was a fetus or a meal.) Nearby were a collection of sharks teeth, indicating that the whales carcass was consumed by sharks after it died.. Wadi al-Hitan was designated a UNESCO World Heritage Site a ...
NARRATOR:. It is late spring on Kodiak Island, Alaska. The air and the water are growing warmer and the locals have returned to feed. But even against this monumental landscape, all eyes are on the horizon for one of natures most graceful giants: the gray whale. It is here that they begin and end the longest migration of any mammal - 12,000 miles from the icy waters of the Arctic to the warm lagoons of Baja, Mexico, and back again.. Gray whales have a narrow, tapered head, and a streamlined body. They surface only for a quick spout and breath before disappearing back into the ocean. Instead of teeth, gray whales have baleen, which is like a thick comb made up of long, fine hairs. Diving to the muddy bottom, grey whales scoop up sediment from the ocean floor, filtering out water and mud and trapping plankton and krill.. In the 1700 and 1800s, whalers in search of oil, meat, and baleen hunted gray whales to near extinction. In 1946 an international treaty was signed to provide oversight and ...
Drones seem to be everywhere these days, from backyards to battlegrounds. Scientists are using them too: in this case, to assess the health of endangered North Atlantic right whales. Since drones are small and quiet, they can fly close to whales without disturbing them, bringing back incredibly detailed photographs and samples of microbe-rich blow.
The southern right whales (Eubalaena australis) were intensely exploited in the Southern Hemisphere between the 18th and 20th centuries. Although the species has been protected internationally from commercial whaling since 1935, some populations were further depleted by illegal catches until the early 1970s. Current estimates suggest that there are approximately 7,000 southern right whales, which is thought to represent a small fraction (about 5%) of its population size prior to commerical whaling. Although some populations have shown signs of recovery, the species is still vulnerable and cited under Appendix I of the International Trade of Endangered Species Fauna and Flora (CITES) and on the IUCN red list of endangered species at risk of extinction (IUCN 2000). Current genetic analyses, involving the use of mithocondrial and nuclear markers (e.g. microsatellites), has focused on the existent levels of genetic variability and extent of gene flow with other wintering grounds (e.g. Peninsula ...
The initial sighting of the gray whale is exhilarating. The blow-a puff of steam standing up to 12 feet off the water-will appear; where there is one blow, others are sure to follow as whales tend to travel in groups of two to six. An amazing maneuver the whales perform is spyhopping. A whale may stick its head above water one or more times consecutively-it is believed that the whale is either getting bearings or using gravity to help swallow. The most dramatic and exciting behavior observed is breaching. The whale will leap out of the water and fall to its side or back making a spectacular splash. This behavior can be perceived as a form of communication to other whales in the area or means of back scratching to release the numerous parasites from the whales hides ...
While Nantuckets whaling industry died in the mid-nineteenth century, commercial whaling endured elsewhere throughout the twentieth century. Ports in the United States and around the world continued to send ships in pursuit of whales to harvest oil, meat, and bones.. During this time, whaling became increasingly efficient. Steam-powered ships could pursue fin whales, which had been too fast to catch using sailing vessels and rowed whaleboats. Harpoon cannons that fired projectiles with exploding heads were able to kill whales with a single shot. These improvements, coupled with a rapid expansion of whaling after World War II, had a catastrophic effect on whale populations worldwide, with hundreds of thousands of whales harvested in just the last half of the twentieth century.. By the 1960s, people increasingly saw whales as majestic, intelligent creatures and not just sources of profit. Works like Farley Mowats Sea of Slaughter and A Whale for the Killing, coupled with a greater awareness of ...
Hi Jake , Ill try to get you a little closer to an ID . From the growth plates being totally fused and not even visible we know it is from a totally mature whale . From the shape and from those wide lateral processes we know it is one of the biggest lumbar vertebrae on that whale . From the shape of the bone we know it isnt from a right whale or a sperm whale . From the appx 30 cm diameter body, it has to come from a whale 12.5-14 meters long . This leaves it being a rorqual whale bigger than a minke and smaller than a fin whale ...
MELBOURNE, FLA. - Scientists have found that a genetic mutation in the eyes of right whales that hampers their ability to see in bright light may make them more susceptible to fatal entanglements in fishing gear, one of the major causes of death for this critically endangered mammal.. The study of this whale species, which numbers less than 500 individuals remaining in the Western Atlantic Ocean, may also help scientists better understand how vision works in other mammals, including people.. Florida Institute of Technology doctoral student Lorian Schweikert and her adviser, Michael Grace, professor of neuroscience and senior associate dean of science, worked with Jeffry Fasick, an assistant professor of biology at the University of Tampa, to characterize this newly discovered mutation in Northern right whales and Bowhead whales. Their results suggest that this mutation may seriously harm the whales ability to visually avoid entanglement.. According to their new study, Evolutionary Loss of Cone ...
After studying the dead whale in Monterey Bay for over a year and half, Vrijenhoek and Goffredi have come to the conclusion that the two new worm species are but the tip of the iceberg (or perhaps the tip of the whale s tail). Whale carcasses-or whale falls, as they are called-represent a massive input of food into the generally food-limited environment of the deep sea. One whale fall can provide as much organic material as thousands of years of marine snow, the organic debris that drifts down from surface waters to sustain life in the deep. Whale-fall specialist Craig Smith of the University of Hawaii has identified entire ecosystems with hundreds of different animals that have developed around a single whale fall. Some of these communities may be sustained for decades on the oil-saturated whale bones. The MBARI scientists will describe the unusual animal community at the Monterey Canyon whale fall in a paper to be published in the October 2004 issue of Deep Sea Research ...
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.. The stranding of hundreds of whales on the New Zealand coastline was harrowing in the television pictures which showed the helplessness of these magnificent creatures when out of their environment, stranded ashore and the enormous efforts of human beings to refloat them. 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. NCB Ireland was 85 feet long and the whale seemed, to my eyes, to be just as big and very close to the boat. I was awed ...

Minke whales feed on fish and various invertebrates; like all baleen whales they filter their food from the water using their baleen plates like sieves. Although largely a solitary species, when feeding minke whales can often be seen in pairs, and on particularly good feeding grounds up to a hundred individuals may congregate. A number of feeding techniques have been observed, including trapping shoals of fish against the surface of the water. After a ten month gestation period, births occur in mid-winter, at birth the calf measures up to 2.8 metres in length. It will be weaned at four months of age, and will stay with its mother for up to two years, becoming sexually mature at seven years of age. Minke whales have an average life span of around 50 years. Minke whales are rather inquisitive and often swim by the side of boats for up to half an hour ...

The spatial distribution of Antarctic minke whales in the Ross Sea with relation to spatial distributions of their prey - krill - was investigated in this study using generalized additive models (GAMs). Spatial distributions of two species of krill (ice and Antarctic krill) were estimated by GAMs. Three abiotic factors - distance from the continental shelf break (800 m isobaths), the mean temperature and salinity from the surface to 200 m (MTEM-200 and MSAL-200), and latitude and longitude - were used as covariates for models of krill. Estimated spatial distributions of krill were then used with other covariates to model the spatial distribution of Antarctic minke whales. In the selected model of Antarctic minke whales, Antarctic krill were more influential than ice krill. The number of Antarctic minke whales increased as the density of Antarctic krill increased to around 1.5 g m−2. Beyond that, the number of Antarctic minke whales decreased as the density of Antarctic krill increased. High ...

The behaviour evident for the various North Atlantic fin whale populations following earlier reductions through whaling differs. It ranges from clear evidence of recovery to no firm indications of any increase. An estimated 14,000 fin whales were killed off North Norway during 1876-1904, and a further 1,500 during 1948-71, but fin whales are rare there now (although quite abundant off western Spitsbergen, where about 1,500 whales had been killed during 1904-11) (Øien 2003, 2004). An estimated 12,000 fin whales were killed off Iceland during 1890-1915, until whaling was suspended partly due to concerns about the reductions in the stocks, but the modern abundance data suggest that the there has been a recovery in the population that may still be continuing, particularly west of Iceland, despite catches during 1948-89 averaging about 220 per year (Branch and Butterworth 2006). An estimated 10,000 fin whales were taken from the Faeroes, but about 25% of these were actually caught off eastern ...
Human-induced mortality from vessel collisions and bycatch in fishing gear (Panigada et al. 2006), together with the potential effects of the disturbance caused by growing whale watching activities, lead to the inference that the subpopulation is declining. Fin Whales have been described as particularly abundant during the summer months in the Corso-Ligurian-Basin, which is considered their major feeding ground in the Mediterranean Sea. A sharp decrease in Fin Whale abundance has been observed in the Pelagos Sanctuary over the last decade, with estimates of 900 individuals reported from the western Ligurian Sea in 1992 (Forcada et al. 1995), declining to significantly lower numbers (N=147; CV=27.04%; 95% CI=86-250) in 2009 (Panigada and Lauriano pers. comm.). While the sharp decrease of Fin Whales in the Pelagos Sanctuary may be due to whales relocating elsewhere within the Mediterranean, their decrease in prime Fin Whale habitat must be addressed with precaution, and a population decline in the ...
Pilot whales have a tendency to follow conspecific pilot leaders, which may explain their common name and also make them particularly vulnerable to drive fisheries and mass stranding events (Kritzler, 1952; Fehring and Wells, 1976; Ellis, 1982). Long-finned pilot whales (Globicephala melas Traill 1809) inhabit the deep waters of the North Atlantic and feed on squid and other prey normally found down to 600 m (Baird et al., 2002; Aguilar Soto et al., 2008). They do not usually dive as deeply as other pelagic odontocete cetaceans such as beaked whales or sperm whales (Heide-Jorgensen et al., 2002). Long-finned pilot whales are very similar to the short-finned pilot whale (Globicephala macrorhynchus) and differ primarily by the habitats they occupy, the long-finned pilot whale being found primarily in subpolar oceanic regions while the short-finned pilot whale is found in tropical and subtropical regions. Both species are classified as Data Deficient on the IUCN Redlist and have been included in ...
Cook Inlet belugas are one of five populations of belugas recognized within U.S. waters. The other beluga populations, which are not listed as threatened or endangered, summer in Bristol Bay, the eastern Bering Sea, the eastern Chukchi Sea and the Beaufort Sea. Of the five populations of beluga whales in Alaska, the Cook Inlet population is considered to be the most isolated based on the degree of genetic differentiation and geographic distance between the Cook Inlet population and the four other beluga populations. The recovery of Cook Inlet whales is potentially hindered by severe stranding events; continued development within and along upper Cook Inlet; industrial and municipal activities that discharge or accidentally spill pollutants; disease; predation by killer whales and losses of available prey to fishing or loss of prey habitat. Protecting habitat is essential to the beluga whales recovery.. Comments on the proposed critical habitat area must be received by Jan. 31, 2010. Send ...
Balaenoptera borealis are part of the Rorquals, a group of baleen whales which include the largest animals on Earth. Sei Whales are the third largest whale after Blue Whales and Fin Whales. Their common name, sei originates from the Danish word for Pollock fish and hval is whale in Danish. These whales were named after Pollock because they were seen in abundance while Norwegian fishers hunted for Pollock fish.. Sei Whales are baleen whales, which refers to the structure of their teeth. Instead of the common mammal tooth form, baleen whales have plates for filtering foods in and filtering water out. Different baleen plate forms emphasize the type of prey food they eat; thus baleen whales tend to be specialists in their diet. Sei Whales are unique in that unlike most rorquals, they are capable of eating all types of micro-crustacean species, making it easier for this species to adapt to its environment. B. borealis also happens to be the fastest swimmer among the baleen whales. They can gain ...
During foraging dives, sperm whales (Physeter macrocephalus) produce long series of regular clicks at 0.5-2 s intervals interspersed with rapid-click buzzes called creaks. Sound, depth and orientation recording Dtags were attached to 23 whales in the Ligurian Sea and Gulf of Mexico to test whether the behaviour of diving sperm whales supports the hypothesis that creaks are produced during prey capture. Sperm whales spent most of their bottom time within one or two depth bands, apparently feeding in vertically stratified prey layers. Creak rates were highest during the bottom phase: 99.8% of creaks were produced in the deepest 50% of dives, 57% in the deepest 15% of dives. Whales swam actively during the bottom phase, producing a mean of 12.5 depth inflections per dive. A mean of 32% of creaks produced during the bottom phase occurred within 10 s of an inflection (13 x more than chance). Sperm whales actively altered their body orientation throughout the bottom phase with significantly ...

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 ...
This action plan addresses the entire set of populations of Blue, Fin, Sei and North Pacific Right Whales (Balaenoptera musculus, B. physalus, B. borealis, and Eubalaena japonica) in Canadian Pacific waters. It identifies recovery measures to implement the broad goals and objectives outlined in the Recovery Strategy for Blue, Fin and Sei Whales in Pacific Canadian Waters (Gregr et al. 2006), and the Recovery Strategy for North Pacific Right Whales (DFO 2011). All four species are being considered together because of their similar geographic distribution, common threats to survival, and the efficiency of integrating activities and resources required for recovery.
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:. ...
A Global Assessment of Gold, Titanium, Strontium and Barium Pollution Using Sperm Whales (Physeter Macrocephalus) As an Indicator Species Abstract.
Grade Two Orcas live in the north Pacific and Atlantic oceans and the cold Antarctic seas. They like colder water. They do not really migrate like other whales. They follow food. They sometimes swim past Port Alice. It is exciting when they show up. Killer Whales (orca) are toothed whales. They are called Killer Whales because their powerful mouth can eat other animals. They eat porpoises, seals, walruses, salmon, and other kinds of small fish. They eat one fish at a time and swallow them whole. Sometimes Killer Whales will attack newborn whales or whales bigger than themselves. They eat nearly a ton of food a day. Orcas live and hunt in pods or family groups. When they are hunting and find a school of fish they make a clicking sound like a squeaky door. Orcas can send out sounds strong enough to stun fish. Killer Whales have the longest dorsal fin of all whales. It helps them keep steady in the water. They are good divers. When they go under the water they close their blow hole, when they ...
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 first recorded cetacean in captivity was a beluga whale that lived in the Boston Aquarial and Zoological Gardens (PDF) in 1861. Later that year, P.T. Barnum (the eventual founder of the Barnum and Bailey Circus) displayed two beluga whales in the basement of his New York City American Museum (not the American Museum of Natural History), followed by at least nine whales that lived and died while on display by Barnum between 1861 and 1865. Throughout the 1870s several aquariums in the United States and in Europe began to showcase particular whale species, such as beluga whales and oceanic dolphins, though few were able to keep them alive for very long. In 1938, Floridas Marine Studios, initially built as a film location for underwater productions, was quickly reinvented into a tourist attraction once the owners discovered the dolphins theatrical talents. It wasnt until the 1950s and 60s that people realized dolphins could be trained to perform elaborate tricks and routines. The U.S. Navy ...
Humpback whales are mid-sized baleen whales that frequent our area in the summer months. They get their name Humpback from a small hump on their back located just in front of their small dorsal fin. These whales have a black body with white flippers (pectoral fins). These flippers are the longest of any whale, reaching up to 15 feet. This can be a third of the whales body length! The underside of the flukes (tail) vary in color from all white to all black with everything in between. These color patterns are unique to each whale, and allow scientists to identify individuals and keep track of them. Humpbacks also have a number of bumps on their heads, called tubercles, each containing one hair. Scientists believe the whales use these hairs as a sensory device. They have anywhere from 270-400 baleen plates on each side of their mouth ...
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, ...
Increased whaling numbers contrary to scientific and international decisions. WASHINGTON, DC: A coalition of international whale protection organisations today strongly condemned the start of Norways 2017 whaling season, which began on April 1.. The coalition believes the hunt could result in the cruel slaughter of up to 999 minke whales, a self-allocated quota more than 100 higher than that set by the Norwegian Government in 2016. In addition, 90 percent of the minke whales hunted by Norways whaling industry are females and almost all of them are pregnant, effectively nearly doubling the actual death toll and seriously impacting future generations of the species.. The increased quota comes as domestic demand for whale meat has flagged and international exports of Norwegian whale products have escalated, in contravention of global bans on both commercial whaling and international trade in whale products.. This years whaling quota, which is not authorised by the International Whaling ...
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.
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 continued recovery of great whales may help to buffer marine ecosystems from destabilizing stresses, the team of scientists writes. This recovered role may be especially important as climate change threatens ocean ecosystems with rising temperatures and acidification. As long-lived species, they enhance the predictability and stability of marine ecosystems, Roman said. Baleen and sperm whales, known collectively as the great whales, include the largest animals to have ever lived on Earth. With huge metabolic demands - and large populations before humans started hunting them - great whales are the oceans ecosystem engineers: they eat many fish and invertebrates, are themselves prey to other predators like killer whales, and distribute nutrients through the water. Even their carcasses, dropping to the seafloor, provide habitat for many species that only exist on these whale falls. Commercial whaling dramatically reduced the biomass and abundance of great whales.. As humpbacks, gray ...
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 ...
Many proteoglycans (PGs) in the tumor microenvironment have been shown to be key macromolecules that contribute to biology of various types of cancer including proliferation, adhesion, angiogenesis and metastasis, affecting tumor progress. The four main types of proteoglycans include hyaluronan (HA), which does not occur as a PG but in free form, heparan sulfate proteoglycans (HSPGs), chondroitin sulfate proteoglycans (CSPGs), dematan sulfate proteoglycans (DSPG) and keratan sulfate proteoglycans (KSPGs) [BR:00535]. Among these proteoglycans such as HA, acting with CD44, promotes tumor cell growth and migration, whereas other proteoglycans such as syndecans (-1~-4), glypican (-1, -3) and perlecan may interact with growth factors, cytokines, morphogens and enzymes through HS chains [BR: 00536], also leading to tumor growth and invasion. In contrast, some of the small leucine-rich proteolgycans, such as decorin and lumican, can function as tumor repressors, and modulate the signaling pathways by ...

In a recent study to be published on April 27, 2011, in the peer-reviewed open-access journal PLoS ONE, Dr. Elliott Hazen and colleagues found that oceanographic and prey measurements can be used to identify beaked whale foraging habitat. The research team from Duke University, Woods Hole, and the Naval Undersea Warfare Center listened for foraging beaked whales and measured ocean features and distributions of prey off the east coast of Andross Island in the Bahamas.. Their manuscript provides evidence that these difficult to study deep-diving creatures use specific ocean features such as salinity and temperature to find their prey. This is the first study describing their distribution and feeding habitat relative to ocean features Blainevilles beaked whales regularly dive over 1000 meters for over an hour in search of prey which varies from 400-1000 meters. The shy and elusive toothed whales feed primarily on fish and squid in the oceans deep scattering layer, an important prey resource for ...
Importance Head of the sperm whale contains 3-4 tons of spermaceti, a substance valued as a lubricant for fine machinery and a component of automatic transmission fluid. It is also used in making ointments and fine, smokeless candles (once it solidifies into a white wax upon exposure to air). The sperm whale has also been a target of commercial whaling in years gone by, in areas around the world. The meat of the whale was not generally consumed, except in Japan. Instead, spermaceti was extracted from the head, and the teeth were often used as a medium for the artistic form of engraving and carving known as scrimshaw. The most important product obtained from sperm whales is the oil, once used as fuel for lamps and now used as a lubricant and as the base for skin creams and cosmetics. A gummy substance called ambergris forms in the large intestines of sperm whales and can be found floating on the surface of the water or washed ashore once it is expelled.

ORLANDO, Fla. (AP) - SeaWorld Orlando says a beluga whale died shortly after it was born at the theme park and an investigation has begun into the cause of death.. The Orlando Sentinel reports that theme park officials say the calf was born this past week but was unusually weak and rose to the surface briefly before sinking to the bottom of a pool. Its mother was 17-year-old Whisper, who has lived at SeaWorld Orlando since 2010.. SeaWorld said animal care teams tried to revive the calf but were unable to save it. The cause of the newborn whales death is unclear.. Park officials say they will run a full post-mortem examination, which could take several weeks before results are finalized. They also say Whispers pregnancy appeared normal.. Copyright 2017 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.. ...
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 ...
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 ...
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 ...

When a dead whale washes up on a beach in a national park, it is definitely not cause for celebration. On the contrary, there is anguish, worry, and a flurry of activity to investigate, especially if mortality may have been caused by human factors. On the bright side, people are fascinated by whales, thus a stranding provides a rare opportunity for a close look at a wild, ocean-dwelling animal whose body can usually only be glimpsed as it surfaces for air. A dead whale is also a treasure trove of biological information, especially in the case of identified individuals whose life history is known.. In this project, supported by a Coastal Marine Grant administered by the National Park Foundation, we learned that by preparing two spectacular and beautiful whale skeletons for display, it is possible to turn the tragic death of a magnificent animal into an inspiring educational opportunity. This is a story of two whales: an adult female humpback whale known as Snow whose Tlingit name is Tsalxaan ...

Whaling is the practice of hunting whales, mainly baleen and sperm whales. This activity has gone on since the Stone Age. In the Middle Ages, reasons for whaling included their meat, oil usable as fuel and the jawbone, which was used in house construction. At the end of the Middle Ages, early whaling fleets aimed at baleen whales, such as bowheads. In the 16th and 17th centuries, the Dutch fleet had about 300 whaling ships with 18,000 crewmen. In the 18th and 19th centuries, baleen whales especially were hunted for their baleen, which was used as a replacement for wood, or in products requiring strength and flexibility such as corsets and crinoline skirts. In addition, the spermaceti found in the sperm whale was used as a machine lubricant and the ambergris as a material for pharmaceutical and perfume industries. In the second half of the 19th century, the explosive harpoon was invented, leading to a massive increase in the catch size. Large ships were used as mother ships for the whale ...
