Non-purulent meningoencephalomyelitis of a Pacific striped dolphin (Lagenorhynchus obliquidens). The first evidence of morbillivirus infection in a dolphin at the Pacific Ocean around Japan. (1/279)

On March 22, 1998, a mature, male, hyposthenic Pacific striped dolphin (Lagenorhynchus obliquidens) was stranded at Aoshima Beach in Miyazaki prefecture, Japan. A necropsy performed 14 hr after death revealed mild diffuse congestion and edema of the leptomeninges and mild pulmonary atelectasis. Histopathologically, non-purulent inflammatory were observed throughout the cerebrum, thalamus, midbrain, pons, medulla oblongata, and spinal cord. Hematoxylin and eosin stain revealed no viral inclusion bodies. Immunohistochemistry using a monoclonal antibody against nucleoprotein of canine distemper virus (CDV-NP) revealed a number of CDV-NP-positive granular deposits in the cytoplasm and cell processes of the degenerating or intact neurons. The present paper is a first report of spontaneously occurred morbillivirus infection in a dolphin at the Pacific Ocean around Japan.  (+info)

Dermatitis with invasive ciliated protozoa in dolphins that died during the 1987-1988 Atlantic Bottlenose Dolphin morbilliviral epizootic. (2/279)

Dermatitis with intradermal cilated protozoa was identified in 18 of 95 (19%) Atlantic Bottlenose Dolphins (Tursiops truncatus) that died during the 1987-1988 Atlantic-dolphin morbillivirus epizootic. The lesions were characterized by focally extensive suppurative and histiocytic dermatitis and cellulitis with ulceration and variable numbers of dermal and hypodermal ciliates. Vasculitis, thrombosis, and/or intravascular ciliates were rarely present. In one dolphin, there was an associated lymphadenitis with ciliates, and in another, bronchopneumonia with rare intrabronchiolar ciliates. Ten of the dolphins were female, and eight were male. The animals ranged in length from 148 to 260 cm. Eleven were from Virginia, four were from New Jersey, and three were from Florida. In 13 dolphins, results of immunohistochemical and/or polymerase chain reaction (PCR) tests were positive for morbillivirus infection. Results of immunohistochemical tests were negative in four dolphins that were not also tested with PCR. Results were also negative in one dolphin tested using both methods. Nine dolphins had concomitant bacterial, fungal, and/or other protozoal infections. Fourteen other dolphins with ciliate-associated dermatitis were identified from 414 Atlantic bottlenose dolphin cases (3%) archived at the Armed Forces Institute of Pathology. The incidence of dermatitis with invasive ciliates is much greater in dolphins that died during the 1987-1988 epizootic.  (+info)

Genomic fingerprinting and development of a dendrogram for Brucella spp. isolated from seals, porpoises, and dolphins. (3/279)

Genomic DNA from reference strains and biovars of the genus Brucella was analyzed using pulsed-field gel electrophoresis (PFGE). Fingerprints were compared to estimate genetic relatedness among the strains and to obtain information on evolutionary relationships. Electrophoresis of DNA digested with the restriction endonuclease XbaI produced fragment profiles for the reference type strains that distinguished these strains to the level of species. Included in this study were strains isolated from marine mammals. The PFGE profiles from these strains were compared with those obtained from the reference strains and biovars. Isolates from dolphins had similar profiles that were distinct from profiles of Brucella isolates from seals and porpoises. Distance matrix analyses were used to produce a dendrogram. Biovars of B. abortus were clustered together in the dendrogram; similar clusters were shown for biovars of B. melitensis and for biovars of B. suis. Brucella ovis, B. canis, and B. neotomae differed from each other and from B. abortus, B. melitensis, and B. suis. The relationship between B. abortus strain RB51 and other Brucella biovars was compared because this strain has replaced B. abortus strain 19 for use as a live vaccine in cattle and possibly in bison and elk. These results support the current taxonomy of Brucella species and the designation of an additional genomic group(s) of Brucella. The PFGE analysis in conjunction with distance matrix analysis was a useful tool for calculating genetic relatedness among the Brucella species.  (+info)

How dolphins use their blubber to avoid heat stress during encounters with warm water. (4/279)

Dolphins have been observed swimming in inshore tropical waters as warm as 36-38 degrees C. A simple protocol that mimicked the thermal conditions encountered by a dolphin moving from cool pelagic to warm inshore water was used to determine how dolphins avoid hyperthermia in water temperatures (Tw) at and above their normal core temperature (Tc). Tw (2 sites), rectal temperature (Tre; 3 depths), and skin temperature (Tsk; 7 sites) and rate of heat flow (4-5 sites) between the skin and the environment were measured while the dolphin rested in a chamber during a 30-min baseline and 40-60 min while water was warmed at approximately 0.43 degrees C/min until temperatures of 34-36 degrees C were attained. Instead of the expected increase, Tre consistently showed declines during the warming ramp, sometimes by amounts that were remarkable both in their magnitude (1.35 degrees C) and rapidity (8-15 min). The reduction in Tre occurred even while heat loss to the environment was prevented by continued controlled warming of the water that kept Tw slightly above Tsk and while metabolic heat production alone should have added 1.6-2 degrees C/h to the Tc. This reduction in Tc could only be due to a massive redistribution of heat from the core to the blubber layer.  (+info)

Epidermal diseases in bottlenose dolphins: impacts of natural and anthropogenic factors. (5/279)

Experimental studies have highlighted the potential influence of contaminants on marine mammal immune function and anthropogenic contaminants are commonly believed to influence the development of diseases observed in the wild. However, estimates of the impact of contaminants on wild populations are constrained by uncertainty over natural variation in disease patterns under different environmental conditions. We used photographic techniques to compare levels of epidermal disease in ten coastal populations of bottlenose dolphins (Tursiops truncatus) exposed to a wide range of natural and anthropogenic conditions. Epidermal lesions were common in all populations (affecting > 60% of individuals), but both the prevalence and severity of 15 lesion categories varied between populations. No relationships were found between epidermal disease and contaminant levels across the four populations for which toxicological data were available. In contrast, there were highly significant linear relationships with oceanographic variables. In particular, populations from areas of low water temperature and low salinity exhibited higher lesion prevalence and severity. Such conditions may impact on epidermal integrity or produce more general physiological stress, potentially making animals more vulnerable to natural infections or anthropogenic factors. These results show that variations in natural environmental factors must be accounted for when investigating the importance of anthropogenic impacts on disease in wild marine mammals.  (+info)

Cloning and sequencing of a bottle-nosed dolphin (Tursiops truncatus) interleukin-4-encoding cDNA. (6/279)

Using polymerase chain reaction (PCR), a bottle-nosed dolphin (Tursiops truncatus) interleukin-4 (IL4) cDNA was cloned and sequenced. IL4 specific primers were based on the 5' and 3' untranslated regions of the human and murine IL4 gene. The dolphin IL4 cDNA is 528 base pairs in length and contains an open reading frame of 402 nucleotides coding an IL4 precursor of 133 amino acids, with the putative signal peptide of 24 amino acids. Analysis of the mature amino acid sequence shows three potential N-linked glycosylation sites and three disulfide bonds. Comparison of the predicted amino acid sequence shows that dolphin IL4 shares 77, 74, 58 and 41% identity with the bovine, ovine, human and mouse IL4s, respectively.  (+info)

Morphology of the lymphoid organs of the bottlenose dolphin, Tursiops truncatus. (7/279)

The anatomy of the lymphoid organs was studied during the course of detailed dissections of 50 beach-stranded bottlenose dolphins, Tursiops truncatus. Constant lymph nodes occur in 4 groups, based on their location and structure. These groups are somatic, including nodes of the cervical region and pelvic recess; lung-associated, included marginal, diaphragmatic and hilar nodes; visceral, including the mesenteric, pancreatic, pericolic and porta hepatis nodes; and aortic arch nodes. Lymphatic drainage of the lung is primarily to the marginal and diaphragmatic nodes. The mesenteric node mass is well-endowed with capsular and trabecular smooth muscle, and a network of muscle fascicles within the organ implies an important contractile function in the circulation of lymph. In addition to constant nodes, occasionally nodes are found in relation to the thoracic aorta, the kidney, and under the scapula. Gut-associated structures include dorsal and ventral oropharyngeal tonsils, mucosal aggregates in the straight segment of the intestine (colon) and anal tonsils; this gut-associated lymphoid tissue tends to involute with age, being greatly reduced by puberty. Formed lymphoid organs include the thymus and the spleen, the latter being relatively small in relation to body size. None of these structures is unique among cetaceans, but the anal tonsils are particularly well developed in T. truncatus. The lymphoid aggregates in the colon resemble the arrangement in the vermiform appendix, which is lacking in most cetaceans, and may have functions analogous to that organ.  (+info)

What determines the bending strength of compact bone? (8/279)

The bending strength of a wide variety of bony types is shown to be nearly linearly proportional to Young's modulus of elasticity/100. A somewhat closer and more satisfactory fit is obtained if account is taken of the variation of yield strain with Young's modulus. This finding strongly suggests that bending strength is determined by the yield strain. The yield stress in tension, which might be expected to predict the bending strength, underestimates the true bending strength by approximately 40 %. This may be explained by two phenomena. (1) The post-yield deformation of the bone material allows a greater bending moment to be exerted after the yield point has been reached, thereby increasing the strength as calculated from beam formulae. (2) Loading in bending results in a much smaller proportion of the volume of the specimens being raised to high stresses than is the case in tension, and this reduces the likelihood of a weak part of the specimen being loaded to failure.  (+info)

The false killer whale has been known to interact non-aggressively with several dolphin species: the common bottlenose dolphin, the Pacific white-sided dolphin (Lagenorhynchus obliquidens), the rough-toothed dolphin (Steno bredanensis), the pilot whales, the melon-headed whale, the pantropical spotted dolphin (Stenella attenuata), the pygmy killer whale, and Rissos dolphin.[17][6][7] The false killer whale may respond to distress calls and protect other species from predators, aid in childbirth by helping to remove the afterbirth, and has been known to interact sexually with bottlenose dolphins and pilot whales,[6] including homosexually.[18] It has been known to form mixed-species pods with those dolphins, probably due to shared feeding grounds. In Japan, these only occur in winter, suggesting it is tied to seasonal food shortages.[7][6][13] A pod near Chile had a 15 km/h (9.3 mph) cruising speed, and false killer whales in captivity were recorded to have a maximum speed of 26.9-28.8 km/h ...
River dolphins are a very widespread group of fully aquatic mammals that reside exclusively in freshwater or brackish water. They are an informal grouping of dolphins, which is a paraphyletic group within the infraorder Cetacea. The river dolphins comprise the extant families Platanistidae (the Indian dolphins), Iniidae (the Amazonian dolphins), and Pontoporiidae (the brackish dolphins). There are five extant species of river dolphins, and two subspecies. River dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla, with even-toed ungulates, and their closest living relatives the hippopotamuses, having diverged about 40 million years ago. River dolphins are relatively small compared to other dolphins, having evolved to survive in warm, shallow water and strong river currents. They range in size from the 5-foot (1.5 m) long South Asian river dolphin to the 8-foot (2.4 m) and 220-pound (100 kg) Amazon river dolphin. Several species exhibit sexual dimorphism, in that the males are ...

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 ...
In 2005, three fishermen, with artisan fishing vessels and drift gillnets, accidentally captured around 200 dolphins between Vigia and Salinópolis in the Amazon River estuary. The dolphins died and they then prepared their vaginas and penises in order to sell them in the Ver-ao-Peso market in the city of Belem within the Brazilian state of Pará. We randomly sampled a minimal quantity of tissue of these sexual organs from 78 of these 200 dolphins and we determined the following results after sequencing 689 base pairs (bp) from the mitochondrial control region gene: (1) 96.15% (75/78) of these dolphins belonged to the species Sotalia guianensis. The other species detected were Steno brenadensis, Stenella coeruleoalba and Tursiops truncatus; (2) The levels of gene diversity found in this sample of S. guianensis were high (33 haplotypes, haplotype diversity of 0.917 and nucleotide diversity of 0.0045) compared to gene diversities found in other Brazilian S. guianensis locations; (3) All the population
The article presents a study about the stomach content of a juvenile Bolivian river dolphin (Inia geoffrensis boliviensis), an endemic subspecies of the Amazon River dolphin, found in the upper Madeira River basin in Bolivia. The study finds that the stomach of Bolivian river dolphin contained a mixture of partially digested fish remains and a nematode. It says that the diet of adult Bolivian river dolphins include crabs and unidentified fish species, including members of the Characidae family ...
Bottlenose dolphins have widely spaced eyes, relatively long flippers, a rounded forehead (called a melon), a relatively short, broad snout, and a mouth that seems permanently twisted into a grin. Inside the mouth are as many as 100 teeth. Highly social, bottlenose dolphins often swim in groups of several hundred individuals, and are famous for racing alongside watercraft. Some stay in coastal waters and others swim offshore. In the Atlantic, the coastal dolphins feed mostly on sea trout, croakers, and spot. The offshore population follows the Gulf Stream and feeds on deep-water fish and squid. Three different populations have been identified in the North Pacific: a temperate-water group, a tropical-water group, and a coastal group ...

Yesterday we received an exciting report! An Atlantic White-sided dolphin that stranded in Wellfleet and was released last month was sighted with a huge group of 300-500 dolphins on Sunday May 16, 2010, by Lisa Barrett from the Whale and Dolphin Conservation Society (WDCS) while aboard a Hyannis Whale Watcher vessel. Lisa recognized the orange tag on the animals dorsal fin and began snapping photos. After reviewing the photos we realized it was tag #65, which was identified to be IFAW10-113La, an adult female that stranded on Friday March 26, 2010 in Duck Creek in Wellfleet, MA just behind the pier. It was part of a group of 7 Atlantic White-sided dolphins that stranded mid-day. Unfortunately one calf was found dead as staff arrived, however the remaining six adults appeared to be in good health. They were extracted from the mud (like many of our dolphin strandings this year) and then released that evening at Herring Cove in Provincetown, MA. All six animals were released with orange tags ...

The Ganges and Indus River Dolphins are essentially identical in appearance. They have the long, pointed snout characteristic of all river dolphins. Both the upper and lower jaw sets of teeth are visible even when the mouth is closed. The snout thickens towards its end. The species does not have crystalline eye lens, rendering it effectively blind, although it may still be able to detect the intensity and direction of light. Navigation and the hunt for food is carried out using echo-location. The body is a brownish colour and stocky at the middle. The species has only a small triangular lump in the place of a dorsal fin. The flippers and tail are thin and large in relation to the body size, which is about 2-2.2m in males and 2.4-2.6m in females. The life span and other life history data is unknown.. The species feeds on shrimp and small fish that prefer the waters close to the river bed. Dolphins are usually encountered on their own but have travelled in groups more often historically, when ...
Since 1996, the OCS research team has studied bottlenose dolphins inhabiting Los Angeles waters, California, focusing primarily on the coastal population (see publications). We have found these animals to be present in the area year-round using the Santa Monica Bay and adjacent coastline mostly for feeding on bottom fish. Our past research shows that this area is an important foraging hotspot for this coastal dolphin population.. Since 1996, our research team has also carried out a long-term study on the offshore population of bottlenose dolphins in California, collecting data on these animals up to 40 miles from shore. This is a challenging task considering the logistical difficulties of recording data on these pelagic and wide-ranging animals!. In 2009, our scientists published a scientific paper entitled Ecology and comparison of coastal and offshore bottlenose dolphins (Tursiops truncatus) in California. Results from this investigation highlighted the need for more studies on this offshore ...
Small coastal dolphins endemic to south-eastern Australia have variously been assigned to described species Tursiops truncatus, T. aduncus or T. maugeanus; however the specific affinities of these animals is controversial and have recently been questioned. Historically the southern Australian Tursiops was identified as unique and was formally named Tursiops maugeanus but was later synonymised with T. truncatus. Morphologically, these coastal dolphins share some characters with both aforementioned recognised Tursiops species, but they also possess unique characters not found in either. Recent mtDNA and microsatellite genetic evidence indicates deep evolutionary divergence between this dolphin and the two currently recognised Tursiops species. However, in accordance with the recommendations of the Workshop on Cetacean Systematics, and the Unified Species Concept the use of molecular evidence alone is inadequate for describing new species. Here we describe the macro-morphological, colouration and cranial
The Influence of Man: The Indus River Dolphins have suffered as a result of incidental and direct exploitation. They have been accidentally caught in fishing nets, but have also been hunted for meat, oil and traditional medicines. They are now fully protected in all of their range.. Flippers: The dolphin has very broad flippers to help it stabilise at slow swimming speed.. Reproduction: The gestation period for the dolphins is approximately 10 months and it is believed that the babies are born in spring. When a baby is born it is about 70 cm long (almost the length of a domestic cat and the mother helps it to the surface to breathe. Babies stay close to their mother for the first six months of their life.. Life span: Scientists think that these dolphins can live for approximately 20 years.. Introduction:The Indus River Dolphin is high on the list of the worlds endangered species. There are estimated to be fewer than 1000 of these dolphins remaining in the whole of Pakistan, most of them between ...
The parsimony network of anchovy cyt b sequences displayed similar geographical patterns in the distribution of genetic diversity as that of the dusky dolphin (Figure 6). Most notable similarities were: (1) marked divergence between South American haplotypes from those in the Atlantic and Indian Oceans, and (2) north-south equatorial transgressions in the Pacific Ocean with (3) a putative ancestor in the North Pacific. The correlation between the patterns of divergence between the dusky dolphin and anchovy species are likely related to paleoceanographic conditions during the Pleistocene (Figure 7). In particular, the date of L. obliquidens/L. obscurus divergence is correlated with the cooling and subsequent warming of sea surface temperatures in the EEP, with the point estimate of equatorial transgression occurring toward the end of the cooling period when primary productivity was well beyond its peak (Figure 7). The extension of nutrient rich waters in the EEP likely offered an arena for the ...
Biological samples of free-ranging dolphins are increasingly used to gain information on population structure and ecology. In small cetaceans, the gender of individuals usually cannot be determined at sea, and population sex ratio has to be inferred indirectly. We used molecular sexing to determine the gender of 340 biopsy samples of bottlenose dolphins, Tursiops truncatus, spotted dolphins, Stenella frontalis, and common dolphins, Delphinus delphis, collected around the Azores and Madeira. Sex ratio was globally skewed in favor of males, and differed between species and archipelagos. Skew was probably influenced by the selectivity of biopsy collectors and seasonal or year-round predominance of males in natural populations. Skew was also influenced by sampling duration and intensity. In the Azores, when several samples were successively collected within the same group, the proportion of female samples decreased as a function of sample order. This trend indicated a tendency for females to ...
The Government is now reviewing the Threat Management Plan for Mauis dolphins. As it will determine the future of Mauis dolphins the international spotlight will be on New Zealand. You can make a submission by following the guidelines here. Note: Its a 219 page document, but the key sections to comment on are section 6 - on fishing related threats - and section 7 - on other threats.. You can also write to your MP or to the editor of your local newspaper raising the issue of Mauis dolphin and asking that action be taken to ensure its survival.

Most New Zealanders have pretty strong feelings about countries that go it alone and defy the IWC on whales... yet we are ignoring what they say on dolphins. If Mauis dolphins are wiped out - and they are precariously close - New Zealand would become only the second country in the history of the IWC to sit by and watch the extinction of a cetacean species, after Chinas Yangtze river dolphin was ...
The Amazon river dolphin, genus Inia, is endemic to the major river basins of northern South America. No previous studies have focused on the genetic structure of this genus. In this work, 96 DNA samples from specimens of this genus were collected in the Orinoco basin (four rivers), the Putumayo Riv …
The negative impact of loud anthropogenic sounds on whales and dolphins has been demonstrated in a variety of disturbances of their mode of life. In particular, these sounds have been associated with the stranding of whales and dolphins (Evans and England, 2001). Current mitigation procedures to protect whales and dolphins from intense sound focus primarily on finding and avoiding them. Alternative mitigation strategies might be a reasonable augmentation to current efforts, in particular, strategies based on the abilities of the animals to mitigate the sounds themselves. If warned, and allowed to change their hearing sensitivity, dolphins and whales might be able to protect their hearing via self-mitigation. Previous work on terrestrial species has shown that loud sounds can trigger avoidance behavior as effectively as other noxious stimuli (Belluzzi and Grossman, 1969). Escape/avoidance behavioral responses to sounds have also been established in various seal species (Götz and Janik, 2010). ...
Franciscana dolphins (Pontoporia blainvillei) have a range that hugs the Atlantic coast of Brazil, Uruguay, and Argentina. This species is one of the worlds smallest cetaceans and is a member of the river dolphin family, although it actually lives in coastal waters and estuaries. Females probably begin to have calves between two and five years and probably stay with each calf for some time. Because researchers estimate that between two and five percent of the Fransiscana population near Argentina becomes entangled in fishing nets from small-scale operations each year, the by-catch death rate has a significant impact on the population numbers. By-catch is the biggest impact to small cetacean populations world-wide.. The by-catch in lost Franciscana dolphins is comparable to what the population produces in terms of offspring, says Pablo Bordino of Fundación Aquamarina in Buenos Aires, Argentina. To know that Franciscana family groups are being caught in certain areas allows us to focus our ...
Dolphin Inner Ear Bone Fossil SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Cetaceans closest living relatives are the hippopotamuses, having diverged about 40 million years ago. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetartiodactyla ...
Pathology experts contracted by NOAA have identified the bacteria Brucella in five bottlenose dolphins that died in the northern Gulf of Mexico. These five are among the 580 dolphins in higher than expected strandings that began in February 2010 and are continuing. NOAA has declared it an unusual mortality event, triggering a focused, expert investigation into the cause.. Brucella bacteria are commonly found in populations of marine and terrestrial animals throughout the world, but infection in humans is rare in the U.S., and there are no documented U.S. cases of Brucella in humans originating from marine sources. NOAA advises anyone who sees a stranded dolphin in the Gulf of Mexico region to call 1-877-WHALE HELP (1-877-942-5343). The stranded dolphin should not be touched, and pets should be kept away from the dolphin as well. The public should also avoid touching live dolphins in the wild.. We believe these five dolphins died from brucellosis. Die-offs from bacterial infections could be ...
A virus that has killed 753 bottlenose dolphins along the U.S. Atlantic Coast north of Florida since July 1 has been confirmed in a dead dolphin found on a Jacksonville Beach earlier this month, leading federal officials to test a dolphin that stranded on a local beach this week. A bottlenose dolphin stranded in Ormond Beach on Thursday afternoon and showed visible signs of the virus killing the other dolphins, federal officials said Friday.

The identification of species and population boundaries is important in both evolutionary and conservation biology. In recent years, new population genetic and computational methods for estimating population parameters and testing hypotheses in a quantitative manner have emerged. Using a Bayesian framework and a quantitative model-testing approach, we evaluated the species status and genetic connectedness of bottlenose dolphin (Tursiops spp.) populations off remote northwestern Australia, with a focus on pelagic offshore dolphins subject to incidental capture in a trawl fishery. We analysed 71 dolphin samples from three sites beyond the 50 m depth contour (the inshore boundary of the fishery) and up to 170 km offshore, including incidentally caught and free-ranging individuals associating with trawl vessels, and 273 dolphins sampled at 12 coastal sites inshore of the 50 m depth contour and within 10 km of the coast. Results from 19 nuclear microsatellite markers showed significant population ...

Dolphins are a highly evolved species. Over the years they have adapted themselves to thrive in different climates and to make the most of their maritime habitats. Most species of dolphin can swim or dive for 1000 feet without needing to come up for air. This means that they can cover huge distances quickly, without being slowed down by their need for oxygen. The iconic shape of the dolphin is another feature which has evolved over centuries. Many years ago, dolphins bodies were much straighter which made it more difficult to flee from hungry predators. The bow shape which we associate with dolphins today is one of the dolphin adaptations which allows them to swim much faster, making it easier for them to catch food on the move and to stay out of the way of creatures which could harm them. Dolphin fins used to be made out of bone which made them rigid and inflexible. They have now adapted to have fins made of stiff cartilage. This cartilage preserves the important aerodynamic shape of both the ...

Swimming with dolphin packages are the finest way to go with groups of six to 12 people today. This article is my tribute to the dolphin with the hope that all will come to recognize the true worth of this amazing creature. As much as individuals have enjoyed the dolphin and orca performances at Sea World, I have to agree that there are improved techniques of interacting with them without the need of confining them to what will have to feel like prison. Major Class Tours deliver a water taxi from Masca Beach to Los Gigantes for 10€ for adults and half that price for youngsters. The structured swim is the type of dolphin encounter you will come across in most dolphin applications. The dolphin has a very good image in mythology, as opposed to other creatures that roam the deep blue oceans. Pretty a couple of years ago, I was swimming in the ocean with my son when a dolphin came appropriate up to us ...
Dolphins are highly intelligent social animals. Many species appear to live in cooperative groups, groups that work together. They may live in groups called pods of fewer than five or as many as several thousand. To some extent, group size depends on the availability of food. Within a large group, animals often separate by age and sex.. Dolphins have excellent hearing and communicate with each other by producing a variety of different sounds, often identified as clicks, pulses, and whistles. Some of these sounds may be identifiers for individual animals, but this communication is not well understood. Dolphins living in clear water may also communicate by flipping and flashing patches of color on their bodies.. There are many examples of dolphins working cooperatively. They may work together to locate and round up a school of fish or chase them into shallow water or to attack a predator, an animal that hunts them for food. They have been seen helping newborn or injured animals to the ...

The evolution of dolphins, or Delphinus, is believed to have started with the Pakiectus a four legged, land walking mammal. The Pakiectus dates back to approximately 50 million years ago. Throughout the centuries, these animals have gone through drastic changes to become the modern day dolphin. Along with the Pakiectus, the dolphin is thought to have evolved alongside or from the Ambulocetus, Remingtonocetidae, Protocetid, Basilosaurudae, Dorudontid, Squalodontidae, Aetiocetidae, and Kentriodontidae to eventually become the Delphinus which is found in the Cetacea infraorder.[1][2] The Pakiectus lived near the shallow waters and began to feed on organisms that lived in these waters, which began the transition from terrestrial to aquatic animals. The bone structure of the flipper in the modern dolphin is very similar to the structure found in the Pakiectus legs and hooves, confirming the link between the two organisms.[3] Over the 50 million years of evolution, the ancestors of dolphins adapted ...
Although a partial ferritin subunit sequence of the seal Phoca vitulina (AF246195, unpublished data) has been determined, the entire coding sequences of ferritin subunits in marine mammals were previously unknown. The present study shows the ferritin coding sequences coding for the H and L subunits of six different dolphin species (P. crassidens, L. obliquidens, G. griseus, G. macrorhyncus, T. truncatus, and D. leucas). The predicted secondary structures using the GENETYX-MAC computer program (Robson method) of dolphin ferritin H and L subunits show A, B, C, D, and short E-helices and the L loop connecting B and C helices (data not shown) as in other mammalian species [1-3, 18]. Sequence comparisons between dolphin ferritin and that of other mammalian species strongly suggest similar functions for the H subunit unique ferroxidase [2, 3, 18], the L subunit salt bridge [2, 8, 23] and iron nucleation site [2, 8], subunit dimer formation [8, 18], and the iron channel [8, 18]. A putative ...
Most dolphins have acute eyesight, both in and out of the water, and their sense of hearing is superior to that of humans. Though they have a small ear opening on each side of their head, it is believed that hearing underwater is also if not exclusively done with the lower jaw which conducts the sound vibrations to the middle ear via a fat-filled cavity in the lower jaw bone. Hearing is also used for echolocation, which seems to be an ability all dolphins have. Their teeth are arranged in a way that works as an array or antenna to receive the incoming sound and make it easier for them to pinpoint the exact location of an object. The dolphins sense of touch is also well-developed. However, dolphins lack an olfactory nerve and lobes and thus are believed to have no sense of smell, but they can taste and do show preferences for certain kinds of fish. Since dolphins spend most of their time below the surface normally, just tasting the water could act in a manner analogous to a sense of ...

Sleep last night was a little better for Miss Reagan. Im pretty sure she slept all night and when I woke up at 7:20am, she was laying there awake but still groggy (I think she had just woke up). Shes been a happy girl again today. Super smiley. Super sweet. So much so, we decided to seize the day and take her to do the Dolphin Encounter. We had to take a Ferry out to the island where they have the dolphins. It was a windy ride out there but the water was so amazingly beautiful. Reagan and I did the Dolphin Encounter, while Mike and Reagans nurse Teri did the Dolphin Swim. I definitely think the swim would have been more fun, but Reagan was too young to do it and I was too pregnant!! The Dolphin Encounter was still fun...just not worth the ridiculous amount of money (none of it was, really). Reagan did seem to like the noise that the dolphin made, but she wasnt crazy about him splashing her with water!! It was difficult because I couldnt kneel on the platform like they wanted me to (and hold ...

There is growing awareness of underwater noise in a variety of marine habitats, and how such noise may adversely affect marine species. This is of particular concern for acoustically-specialised species, such as dolphins. In order to ascertain the potential impacts of anthropogenic noise on these animals, baseline information is required for defining the soundscape of dolphin habitats. The Swan-Canning River system in Western Australia flows through the city of Perth, and experiences numerous anthropogenic activities. Despite this, the river system is home to a community of Indo-Pacific bottlenose dolphins (Tursiops aduncus). To provide a baseline soundscape description of dolphin habitat, over 11,600 h of acoustic data were analysed from five sites within the Swan River (from Fremantle Inner Harbour to 20 km upstream) across an eight-year period. Multiple sound sources were recorded at these sites, including: snapping shrimp; fishes; dolphins; pile-driving; bridge and road traffic; and vessel
Parainfluenza virus (PIV) is a leading cause of respiratory infections in humans. A novel virus closely related to human and bovine parainfluenza viruses types 3 (HPIV-3 and BPIV-3), named Tursiops truncatus parainfluenza virus type 1 (TtPIV-1), was isolated from a dolphin with respiratory disease. We developed a dolphin-specific ELISA to measure acute- and convalescent-phase PIV antibodies in dolphins during 1999-2006 with hemograms similar to that of the positive control. PIV seroconversion occurred concurrently with an abnormal hemogram in 22 animals, of which 7 (31.8%) had respiratory signs. Seroprevalence surveys were conducted on 114 healthy bottlenose dolphins in Florida and California. When the most conservative interpretation of positive was used, 11.4% of healthy dolphins were antibody positive, 29.8% were negative, and 58.8% were inconclusive. PIV appears to be a common marine mammal virus that may be of human health interest because of the similarity of TtPIV-1 to BPIV-3 and HPIV-3.
False killer whales are highly unusual in this area. A March sighting of a baby being born next to a whale watching boat off Dana Point drew national attention and had experts amazed.. The calf was born when a pod of about 15 females pushed their way across the ocean near the Dana Point Headlands and huddled against the Manutea, a sailboat operated by Captain Tom Southern, with Capt. Daves Dolphin Safari and Whale Watch. Videos of the live birth went viral.. Forney is a false killer whale specialist. Mostly, she has studied the tropical species in Hawaii where they are more commonly found.. The unusually warm water off Southern California in the last four years has brought the tropical dolphins to the area along with a host of other warm-water species such as the loggerhead turtles, pelagic red crabs, sharks and by-the-wind-sailors - a sort of jellyfish.. Those oddities have also brought a host of sport fish such as yellow fin tuna, dorado and marlin. Those game fish are just what false killer ...
In order to estimate the total bycatch in gillnet fisheries and to assess the impact on dolphin populations in the Menai Bay Conservation Area, a survey using independent observers aboard the fishing vessels was conducted in 2003/2004. The observer programme covered 23.6% and 24.5% of the drift- and bottom set gillnets effort, respectively. The estimated total bycatch was 13 Indo-Pacific bottlenose dolphins in drift gillnets and 4 humpback dolphins in bottom set gillnets representing 9.6% and 6.3%, respectively of the estimated 136 Indo-Pacific bottlenose and 63 humpback dolphins resident in the area in 2002. These bycatch levels were not considered sustainable. In 2007/2008 a second observer programme was conducted in the same area to investigate the effectiveness of acoustic alarms (pingers) in reducing the bycatch of dolphins in the drift- and bottom set gillnets. The observed effort in the drift gillnets was 257 sets without pingers and 251 sets with pingers representing 21% and 20% of the ...
Artificial insemination (AI) with sex-sorted bottlenose dolphin spermatozoa provides female calves for obtaining more cohesive social groups and optimum genetic management of captive populations. However, distance of animals to the sorting facility represents a limit to the procedure. Although one bottlenose dolphin calf has been born using spermatozoa from frozen-thawed, sorted and recryopreserved spermatozoa, critical evaluation of the steps involved in this process is required to maximize its efficiency for future AIs and expansion of the technology to other species. Two experiments were designed to determine the efficiency of the sorting process and the quality of frozen-thawed bottlenose dolphin spermatozoa during sorting and recryopreservation. In experiment 1, the effect of two washing media (with and without 4 percent egg yolk, v/v) following density gradient centrifugation (DGC) on sperm recovery rate and in vitro characteristics of cryopreserved spermatozoa was examined. In experiment ...
A virus similar to measles in humans is being blamed for the deaths of hundreds of Atlantic bottlenose dolphins.. Experts at the US National Oceanic and Atmospheric Administration say the Morbillivirus infects the lungs and the brain, causes pneumonia and abnormal behaviour, and is often fatal.. The outbreak has killed 333 bottlenose dolphins in the mid-Atlantic region since July, and may last for a year, possibly being worse than an outbreak 25 years ago which killed more than 740 animals.. Teri Rowles of the NOAA Fisheries Marine Mammal Health and Stranding Response Program says experts are worried about a repeat of those deaths.. We are expecting that if indeed this plays out the way that die-off occurred, that we are looking at mortality being higher and morbillivirus spreading southward and likely continuing until spring of 2014, she said.. Nine times the average number of dolphins have washed up along the shores of the east coast this summer.. Most of the dolphins found on beaches have ...

A typical killer whale distinctively bears a black back, white chest and sides, and a white patch above and behind the eye. Calves are born with a yellowish or orange tint, which fades to white. It has a heavy and robust body[51] with a large dorsal fin up to 1.8 m (5 ft 11 in) tall.[52] Behind the fin, it has a dark grey saddle patch across the back. Antarctic killer whales may have pale grey to nearly white backs. Adult killer whales are very distinctive, seldom confused with any other sea creature.[53] When seen from a distance, juveniles can be confused with other cetacean species, such as the false killer whale or Rissos dolphin.[54]. The killer whales teeth are very strong, and its jaws exert a powerful grip; the upper teeth fall into the gaps between the lower teeth when the mouth is closed. The firm middle and back teeth hold prey in place, while the front teeth are inclined slightly forward and outward to protect them from powerful jerking movements.[55]. Killer whales are the ...
Dolphins are carnivores, meat eaters. They eat fish and squid and capture their food one fish at a time. The type of fish they prefer depends on the zone of the ocean that they inhabit. Killer whales eat fish, but they also hunt seals, sea lions, other dolphins, whales, porpoises, and sea birds.. Dolphins use echolocation to navigate and find prey. Echolocation allows dolphins to use high-pitch sounds that bounce off objects in order to determine their location. In some species, echolocation is so sensitive that it can locate an object less than 0.5 inch across (1.25 centimeters) at a distance of 50 feet (15 meters).. ...
ABSTRACT: An unusual mortality event (UME) involving primarily common bottlenose dolphins Tursiops truncatus of all size classes stranding along coastal Louisiana, Mississippi, and Alabama, USA, started in early 2010 and continued into 2014. During this northern Gulf of Mexico UME, a distinct cluster of perinatal dolphins (total body length ,115 cm) stranded in Mississippi and Alabama during 2011. The proportion of annual dolphin strandings that were perinates between 2009 and 2013 were compared to baseline strandings (2000-2005). A case-reference study was conducted to compare demographics, histologic lesions, and Brucella sp. infection prevalence in 69 UME perinatal dolphins to findings from 26 reference perinates stranded in South Carolina and Florida outside of the UME area. Compared to reference perinates, UME perinates were more likely to have died in utero or very soon after birth (presence of atelectasis in 88 vs. 15%, p , 0.0001), have fetal distress (87 vs. 27%, p , 0.0001), and have ...
Habitat selection and life history patterns were compared among three species of small cetaceans in the central North Pacific Ocean: Dalls porpoise (Phocoenoides dalli), northern right whale dolphin (Lissodelphis borealis) and Pacific white-sided dolphin (Lagenorhynchus obliquidens). Biological samples and fisheries data used for analysis of habitat preferences were obtained by observers monitoring Japanese high seas squid driftnet operations between 36$\sp\circ$N and 46$\sp\circ$N, and 152$\sp\circ$E and 150$\sp\circ$W during 1990 and 1991. Supplementary data used for analysis of Dalls porpoise life history were collected between 46$\sp\circ$N and 53$\sp\circ$N and 168$\sp\circ$E and 175$\sp\circ$E in the Japanese salmon mothership fishery from 1981 to 1987.The main objective was to determine if habitat partitioning mechanisms could be detected among the three marine mammal species. Two approaches were taken. First, reproductive patterns were compared, with special attention to calving ...
A young false killer whale calf rescued on the west coast of Vancouver Island made it through the night, but the hard work of keeping it alive lies ahead, according to staff at the Vancouver Aquariums Marine Mammal Rescue Centre.
My research interests are diverse but include investigating exposure and effects of persistent organic pollutants (POPs), especially polychlorinated biphenyls (PCBs) in marine apex predator species in European waters such as killer whales (Orcinus orca) and bottlenose dolphins (Tursiops truncatus). This involves longstanding collaborative work with Robin Law, Jon Barber and other colleagues at Cefas Lowestoft laboratory in Suffolk. Although PCB use/manufacture was banned in Europe in the 1980s, blubber PCB concentrations consistently exceed all known thresholds for mammalian toxicity and are likely to be the main driver of marked population declines in European marine apex predators like killer whales (orcas), bottlenose dolphins and striped dolphins (Stenella coeruleoalba) in the NE Atlantic and Mediterranean Sea regions (Jepson et al 2016). PCB concentrations did initially decline in biota following an EU-ban in the mid-1980s, but PCBs have now stabilised in most European biota. For many ...

This joy is often relived now with guests I take to meet the Dolphins of Ponta.. Later on in life I was to learn that dolphins were revered amongst ancient civilizations and to swim with dolphins ranked top on bucket lists. I discovered that dolphins are highly intelligent and are, in essence, persons. I learned that they are befriend-able and if approached in the right way, with the right attitude, these sentient beings would never cease to amaze.. The coastal waters off the east African seaboard are home to populations of semi resident Indo-Pacific, inshore bottlenose dolphins (Tursiops aduncus). These gregarious dolphins are different from their larger and more robust oceanic counterparts Tursiops truncates, the common bottlenose dolphin, in that they freckle on their bellies and have a longer and more slender beak.. The Dolphins of Ponta are one such population. Some 250 individuals live within a complex cross border network which traverses the towering duned coastline and surrounding ...

According to marine biologist Dagmar Fertl, this event was only the third reported sighting of an albino bottlenose dolphin in the Gulf of Mexico (going back to 1994), and the fourteenth spotting anywhere in the world (the first coming in 1962). Biologists speculate that, in addition to the rarity of their birth, the scarcity of albino bottlenose dolphins might be due to their having poor eyesight, increased sensitivity to sunlight, and a coloration that provides poor camouflaging, factors which could significantly decrease their chances of reaching maturity. ...

The false killer whale and short-finned pilot whale are two of the cetacean species that have been observed taken by the longline fishery that operates in the central Pacific, and using our best available data, the false killer whale has been identified as a strategic stock (Nitta and Henderson, 1993; Carretta et al., 2004). Both species are largely pelagic in distribution and are found in tropical and temperate waters of all ocean basins. We have been using the mitochondrial. DNA control region sequences to examine population structure. Our preliminary results show that for both species, the animals sampled around the Hawaiian Islands are separate, reproductively isolated populations and have likely been isolated from animals living in the eastern tropical Pacific for a long time. The data for short-finned pilot whales also suggest additional structure within the eastern tropical Pacific, and that neither species has a strictly matrilineal pod structure.. ...

The feeding performance of two bottlenose dolphins (Tursiops truncatus) and one juvenile pygmy and dwarf sperm whale (Kogia breviceps and K. sima) was compared during controlled feeding trials. Feeding behavior was characterized and a Ram-Suction Index (RSI) measured. The feeding behavior of both genera was composed of four phases: preparatory (Phase I), jaw opening (Phase II), gular depression (Phase III) and jaw closing (Phase IV). The mean Kogia total feeding cycle duration (533 ms; SD±150) was shorter than the mean for Tursiops (847 ms; SD±349). The mean maximum gape angle was greater for Kogia (56.6º; SD±3.3) than for Tursiops (25.5º; SD±8.5). The mean Kogia RSI (-0.04; SD±0.378) was significantly less (p,0.001) than the mean Tursiops RSI (0.71; SD±0.14), indicating a suction and ram-based strategy for Kogia and Tursiops, respectively. The significantly shorter (p,0.05) Kogia jaw opening phase (172 ms; SD±75) supports the RSI results. Tursiops displayed two feeding behaviors, a ...

Prostephanus truncatus (Horn) is a pest of stored maize that has caused major problems since appearing in Africa, though it is regarded as a minor pest in Mexico and Central America. The ability of P. truncatus to feed and breed on a great variety of environments, raises the questions to whether this beetle can break down starch and cellulose. The digestive system of P. truncatus may explain its host range. The digestive systems of adults and larvae of three P. truncatus strains from different geographic regions (Mexico, Togo, and Tanzania) were the subjects of the present work. The anatomical study of the digestive system of P. truncatus shows that the guts of adults and larvae were externally different and that these differences reflect different life spans and their different feeding habits. The internal anatomy, is similar, with the exception of the presence of peritrophic membrane and glycogen-like granules in the midgut of the adult stage. There is a cryptonephric system present in both ...
