An order of wholly aquatic MAMMALS occurring in all the OCEANS and adjoining seas of the world, as well as in certain river systems. They feed generally on FISHES, cephalopods, and crustaceans. Most are gregarious and most have a relatively long period of parental care and maturation. Included are DOLPHINS; PORPOISES; and WHALES. (From Walker's Mammals of the World, 5th ed, pp969-70)
Mammals of the families Delphinidae (ocean dolphins), Iniidae, Lipotidae, Pontoporiidae, and Platanistidae (all river dolphins). Among the most well-known species are the BOTTLE-NOSED DOLPHIN and the KILLER WHALE (a dolphin). The common name dolphin is applied to small cetaceans having a beaklike snout and a slender, streamlined body, whereas PORPOISES are small cetaceans with a blunt snout and rather stocky body. (From Walker's Mammals of the World, 5th ed, pp978-9)
Large marine mammals of the order CETACEA. In the past, they were commercially valued for whale oil, for their flesh as human food and in ANIMAL FEED and FERTILIZERS, and for baleen. Today, there is a moratorium on most commercial whaling, as all species are either listed as endangered or threatened.
Mammals of the family Phocoenidae comprising four genera found in the North Pacific Ocean and both sides of the North Atlantic Ocean and in various other seas. They differ from DOLPHINS in that porpoises have a blunt snout and a rather stocky body while dolphins have a beak-like snout and a slender, streamlined body. They usually travel in small groups.

Fitzgerald factor (high molecular weight kininogen) clotting activity in human plasma in health and disease in various animal plasmas. (1/159)

Fitzgerald factor (high molecular weight kininogen) is an agent in normal human plasma that corrects the impaired in vitro surface-mediated plasma reactions of blood coagulation, fibrinolysis, and kinin generation observed in Fitzgerald trait plasma. To assess the possible pathophysiologic role of Fitzgerald factor, its titer was measured by a functional clot-promoting assay. Mean +/- SD in 42 normal adults was 0.99+/-0.25 units/ml, one unit being the activity in 1 ml of normal pooled plasma. No difference in titer was noted between normal men and women, during pregnancy, or after physical exercise. Fitzgerald factor activity was significantly reduced in the plasmas of eight patients with advanced hepatic cirrhosis (0.40+/-0.09 units/ml) and of ten patients with disseminated intravascular coagulation (0.60+/-0.30 units/ml), but was normal in plasmas of patients with other congenital clotting factor deficiencies, nephrotic syndrome, rheumatoid arthritis, systemic lupus erythematosus, or sarcoidosis, or under treatment with warfarin. The plasmas of 21 mammalian species tested appeared to contain Fitzgerald factor activity, but those of two avian, two repitilian, and one amphibian species did not correct the coagulant defect in Fitzgerald trait plasmas.  (+info)

Purification and properties of whale thyroid-stimulating hormone III. Properties of isolated multiple components. (2/159)

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)

Genealogy of families of SINEs in cetaceans and artiodactyls: the presence of a huge superfamily of tRNA(Glu)-derived families of SINEs. (3/159)

Several novel (sub)families of SINEs were isolated from the genomes of cetaceans and artiodactyls, and their sequences were determined. From comparisons of diagnostic nucleotides among the short interspersed repetitive elements (SINEs) in these (sub)families, we were able to draw the following conclusions. (1) After the divergence of the suborder Tylopoda (camels), the CHRS family of SINEs was newly created from tRNA(Glu) in a common ancestor of the lineages of the Suina (pigs and peccaries), Ruminantia (cows and deer), and Cetacea (whales and dolphins). (2) After divergence of the Suina lineage, the CHR-1 SINE and the CHR-2 SINE were generated successively in a common ancestor of ruminants, hippopotamuses, and cetaceans. (3) In the Ruminantia lineage, the Bov-tA SINE was generated by recombination between the CHR-2 SINE and Bov-A. (4) In the Suina lineage, the CHRS-S SINE was generated from the CHRS SINE. (5) In this latter lineage, the PRE-1 family of SINEs was created by insertion of part of the gene for tRNA(Arg) into the 5' region of the CHRS-S family. The distribution of a particular family of SINEs among species of artiodactyls and cetaceans confirmed the most recent conclusion for paraphyly of the order Artiodactyla. The present study also revealed that a newly created tRNA(Glu)-derived family of SINEs was subjected both to recombination with different units and to duplication of an internal sequence within a SINE unit to generate, during evolution, a huge superfamily of tRNA(Glu)-related families of SINEs that are now found in the genomes of artiodactyls and cetaceans.  (+info)

A review of virus infections of cataceans and the potential impact of morbilliviruses, poxviruses and papillomaviruses on host population dynamics. (4/159)

Viruses belonging to 9 families have been detected in cetaceans. We critically review the clinical features, pathology and epidemiology of the diseases they cause. Cetacean morbillivirus (family Paramyxoviridae) induces a serious disease with a high mortality rate and persists in several populations. It may have long-term effects on the dynamics of cetacean populations either as enzootic infection or recurrent epizootics. The latter presumably have the more profound impact due to removal of sexually mature individuals. Members of the family Poxviridae infect several species of odontocetes, resulting in ring and tattoo skin lesions. Although poxviruses apparently do not induce a high mortality, circumstancial evidence suggests they may be lethal in young animals lacking protective immunity, and thus may negatively affect net recruitment. Papillomaviruses (family Papovaviridae) cause genital warts in at least 3 species of cetaceans. In 10% of male Burmeister's porpoises Phocoena spinipinnis from Peru, lesions were sufficiently severe to at least hamper, if not impede, copulation. Members of the families Herpesviridae, Orthomyxoviridae and Rhabdoviridae were demonstrated in cetaceans suffering serious illnesses, but with the exception of a 'porpoise herpesvirus' their causative role is still tentative. Herpes-like viruses and caliciviruses (Caliciviridae) give rise to cutaneous diseases in Monodontidae and Delphinidae. Antibodies to several serotypes of caliciviruses were found in odontocetes and mysticetes. An unrecognized Hepadnaviridae was detected by serology in a captive Pacific white-sided dolphin Lagenorhynchus obliquidens with chronic persistent hepatitis. Adenoviruses (Adenoviridae) were isolated from the intestinal tracts of mysticeti and a beluga Delphinapterus leucas but were not associated with any pathologies. We discuss the potential impact of Paramyxoviridae, Poxviridae and Papovaviridae on the dynamics of several odontocete populations.  (+info)

Using protein structural information in evolutionary inference: transmembrane proteins. (5/159)

We present a model of amino acid sequence evolution based on a hidden Markov model that extends to transmembrane proteins previous methods that incorporate protein structural information into phylogenetics. Our model aims to give a better understanding of processes of molecular evolution and to extract structural information from multiple alignments of transmembrane sequences and use such information to improve phylogenetic analyses. This should be of value in phylogenetic studies of transmembrane proteins: for example, mitochondrial proteins have acquired a special importance in phylogenetics and are mostly transmembrane proteins. The improvement in fit to example data sets of our new model relative to less complex models of amino acid sequence evolution is statistically tested. To further illustrate the potential utility of our method, phylogeny estimation is performed on primate CCR5 receptor sequences, sequences of l and m subunits of the light reaction center in purple bacteria, guinea pig sequences with respect to lagomorph and rodent sequences of calcitonin receptor and K-substance receptor, and cetacean sequences of cytochrome b.  (+info)

Model dependence of the phylogenetic inference: relationship among carnivores, Perissodactyls and cetartiodactyls as inferred from mitochondrial genome sequences. (6/159)

Some previous analysis of mitochondrial proteins strongly support the Carnivora/Perissodactyla grouping excluding Cetartiodactyla (Artiodactyla + Cetacea) as an outgroup, but the support of the hypothesis remains equivocal from the analysis of several nuclear-encoded proteins. In order to evaluate the strength of the support by mitochondrial proteins, phylogenetic relationship among Carnivora, Perissodactyla, and Cetartiodactyla was estimated with the ML method by using the updated data set of the 12 mitochondrial proteins with several alternative models. The analyses demonstrate that the phylogenetic inference depends on the model used in the ML analysis; i.e., whether the site-heterogeneity is taken into account and whether the rate parameters are estimated for each individual proteins or for the concatenated sequences. Although the analysis of concatenated sequences strongly supports the Carnivora/Perissodactyla grouping, the total evaluation of the separate analyses of individual proteins, which approximates the data better than the concatenated analysis, gives only ambiguous results, and therefore it is concluded that more data are needed to resolve this trichotomy.  (+info)

Elemental analysis of cetacean skull lesions associated with nematode infections. (7/159)

The elemental composition of both healthy and eroded cetacean skulls associated with nematode infections was evaluated. A total of 27 samples of eroded and non-eroded prepared museum cetacean skulls were characterised by elemental (CHN), X-ray fluorescence, and X-ray diffraction methods. The inorganic composition and crystal line structure (hydroxylapatite-like minerals) were similar for both types of skull samples, but the CHN values clearly differed. The results suggest that the carbon-rich fraction is lost in eroded areas, probably as a result of glycosaminoglycan-degrading Crassicauda enzymes.  (+info)

Consistency of SINE insertion topology and flanking sequence tree: quantifying relationships among cetartiodactyls. (8/159)

Short interspersed nuclear elements (SINEs) have been used to generate unambiguous phylogenetic topologies relating eukaryotic taxa. The irreversible nature of SINE retroposition is supported by a large body of comparative genome data and is a fundamental assumption inherent in the value of this qualitative method of inference. Here, we assess the key assumption of unidirectional SINE insertion by comparing the SINE insertion-derived topology and the phylogenetic tree based on seven independent loci of five taxa in the order Cetartiodactyla (Cetacea + Artiodactyla). The data sets and analyses were largely independent, but the loci were, by definition, linked, and thus their consistency supported an irreversible pattern of SINE retroposition. Moreover, our analyses of the flanking sequences provided estimates of divergence times among cetartiodactyl lineages unavailable from SINE insertion analysis alone. Unexpected rate heterogeneity among sites of SINE-flanking sequences and other noncoding DNA sequences were observed. Sequence simulations suggest that this rate heterogeneity may be an artifact resulting from the inaccuracies of the substitution model used.  (+info)

The distribution of cetaceans has always been a difficult and polemic issue, and more so in open waters and pelagic habitats. Due to the high economic cost of surveying and the low detectability of certain cetacean species, the distribution of many cetacean species remains poorly known in many areas. In this work we explore the potential of Spatial Distribution Modelling using presence-only models to obtain a potential distribution map of cetacean populations from opportunistic data. We used opportunistic data from the MONICET database, provided by commercial whale-watching operations in the Azores using a standard, validated, methodology. Two different presence-only models were applied, the Genetic Algorithm for Rule-Set Production (GARP) and the Maximum Entropy Modelling (MaxEnt). Using different GIS programs we prepared a set of different bathimetric derived ecogeographical variables: Depth, Slope, Rugosity and Bathimetric Position Index, using the Bathimetric Terrain Modeller Extension for ...

Archaeoceti (ancient whales), or Zeuglodontes in older literature, is a paraphyletic group of primitive cetaceans that lived from the Early Eocene to the late Oligocene (55 to 23 million years ago). Representing the earliest cetacean radiation, they include the initial amphibious stages in cetacean evolution and are thus the ancestors of both modern cetacean suborders, Mysticeti and Odontoceti. This initial diversification occurred in the shallow waters that separated India and Asia 53 to 45 mya, resulting in some 30 species adapted to a fully oceanic life; though both echolocation and filter-feeding evolved during a second radiation 36 to 35 mya. All archaeocetes from the Ypresian (56-47.8 mya) and most from the Lutetian (47.8-41.3 mya) are known exclusively from Indo-Pakistan, but Bartonian (41.3-38.0 mya) and Priabonian (38.0-33.9 mya) genera are known from across Earth, including North America, Egypt, New Zealand, and Europe. Although there is no consensus regarding the mode of locomotion ...

Cetaceans are exposed to a range of anthropogenic stressors, including, for example, noise, contaminants, habitat degradation, reduced prey availability, ship strike, and entanglement. Tools to assess body condition in these inaccessible and vulnerable animals are required to better understand the energetic consequences of anthropogenic stressors that can impact population health and, ultimately, conservation status. Remotely obtained, dart biopsy samples are becoming an increasingly standard method of tissue collection from live, large cetaceans. Here, the potential ...

The CetMap working group recognized the necessity of creating BIAs to incorporate additional information into the mapping tool by identifying areas where cetacean species or populations are known to concentrate for specific behaviors, or are range-limited, but for which there is not sufficient data for their importance to be reflected in the quantitative mapping effort. The result of the BIA assessment process includes narratives, maps, and tables that provide additional context within which to examine potential interactions between cetaceans and human activities. Our aim for this assessment is to combine expert judgement with available data (published or unpublished) to delineate BIAs for each species and each region. Our goal is not to define marine protected areas. Rather, we are identifying sites where cetaceans engage in activities at certain times that contribute to an individuals health and fitness and, ultimately, to the fecundity and survivor-ship of the population. During the ...

The project to restore the living ecosystem of the Mediterranean, MedRec S.A., was headed by a young superbright Nikolaus Vassiliou, with the assistance of the superturing AI NiarchosII and a team of augmented marine biologists. The devastated waters were soon filled with remote drone submarines and underwater survey teams, including biochipped dolphins (there were as yet no geneered neodolphins) and seals. The difficulties of working in the murky depths led the team to explore new possibilities. Vassiliou was a keen follower of genetic research into the evolution of marine mammals, and was informed by contacts within the bioengineering megacorp IntronTEK (soon after renamed GeneTEK) that mapping and extrapolation of various gene complexes had produced a number of possibly viable genotypes for marine humans. These extrapolations were based on cetacean and pinniped analogues, and sounded ideal for the sort of underwater ecological management his group was engaged in. The plans to gestate the new ...

Neural networks use electronic analogs of the neurons in our brains. But it doesnt seem likely that just making enough electronic neurons would create a human-brain-like thinking machine. Consider that animal brains are sometimes larger than ours - a sperm whales brain weighs 17 pounds - yet we dont think they are as smart as humans or even dogs who have a much smaller brain. MIT researchers have discovered differences between human brain cells and animal ones that might help clear up some of that mystery. You can see a video about the work theyve done below.. Neurons have long finger-like structures known as dendrites. These act like comparators, taking input from other neurons and firing if the inputs exceed a threshold. Like any kind of conductor, the longer the dendrite, the weaker the signal. Naively, this seems bad for humans. To understand why, consider a rat. A rats cortex has six layers, just like ours. However, whereas the rats brain is tiny and 30% cortex, our brains are much ...

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 ...

Cetus is Latin and is used in biological names to mean whale; its original meaning, large sea animal, was more general. It comes from Ancient Greek κῆτος (kētos), meaning whale or any huge fish or sea monster. In Greek mythology the monster Perseus defeated was called Ceto, which is depicted by the constellation of Cetus. Cetology is the branch of marine science associated with the study of cetaceans ...

Identifying the genetic basis of adaptive phenotypes can be a significant step towards understanding how that phenotype evolved. With the increased availability of interspecific molecular data, an approach to uncover such genes has been to search for signatures of adaptive evolution at the molecular level. Many analyses have adopted a candidate gene approach, focusing on genes with important developmental roles. One such candidate gene is ASPM, which is involved in neurogenesis and associated with major neurological disorders [1]. The molecular evolution of ASPM has been investigated for a decade (see electronic supplementary material, table S1), under the hypothesis that it contributes to primate brain evolution. A recent study by Xu et al. [2] extends the taxonomic scope by demonstrating that ASPM evolved adaptively in cetaceans. However, descriptive studies of patterns of selection are now being supplanted by those that explicitly test for gene-phenotype associations. Using such an approach, ...
The cheek teeth [of Aetiocetus] are leaf shaped, similar to those of Patriocetus, but smaller and with the roots coalesced. The triangular rostrum, reduced dentition, and the conformation of the posterior ends of the maxillae, premaxillae, and nasals (Ernlong, 1966:s) are characters that would be expected in the ancestor of the mysticetes. Thenius (1969:489) stated: Even if Aetiocetus, because of its geologic age (upper Oligocene) cannot be a direct stem form of the cetotheres, yet this genus documents that a specific family (Aetiocetidae) must be classified as ancestor, the link between ancient and baleen whales.. Among the few Cetacea known from deposits of middle Oligocene age are two occurrences of unmistakable Mysticeti. One of these, Mauicetus Benham, 1939, from New Zealafid, has long nasals embraced by premaxillae and maxillae which extend posteriorly to the level of the supraorbital process of the frontal, together with an anteriorly thrusting triangular supraoccipital. The Oligocene ...

CMS in collaboration with WWF has published Guidelines for the Safe and Humane Handling and Release of Bycaught Small Cetaceans from Fishing Gear, which set out best practice on how to handle and release small cetaceans accidentally caught in fishing gear. Preventing fisheries bycatch is a top priority to ensure the conservation of species or populations. However, when these efforts fail and small cetaceans are found alive in or on fishing gear, this clear and comprehensive set of guidelines for the fishers involved will be of great benefit.
Solution #1: When the desmostylian, Desmostylus hesperus (Marsh 1888), and the odontocete, Zygorhiza kochii (True 1908), are added to the LRT (Fig. 2) the Odontoceti and the Mysticeti finally nest apart when tested together. Both of these transitional taxa are known from complete skeletons that link them to both ancestors and descendants. The addition of these two taxa makes the transition more seamless.. Solution #2: The RBCM specimen referred to Behemotops includes a partial skull, 12 thoracic vertebrae, 17 rib fragments, a very partial scapula and most of a humerus. Authors Beatty and Cockburn 2015 also report, No other skeletal elements of desmostylians are found anywhere nearby, and the only other bone found in the area was a caudal vertebrae from a Tursiops-sized odontocete. Now, Im no whale expert, ...
3 where dr is the centre-to-centre spacing between the receptors of the retina. This introduces a trade-off, since increasing the focal length of the eye on its own increases the f-number and so decreases sensitivity. One way to achieve both good sensitivity and acuity is to allow the focal length to increase, but simultaneously to increase the aperture size to avoid increasing the f-number. Hence, it may be that the large eyes of ichthyosaurs were a result of simultaneous selection for both high sensitivity and acuity. However, it is interesting to note that the visual acuities of extant cetaceans and pinnipeds are generally good and comparable with those of terrestrial hunters such as the domestic cat Felis catus (Muir and Mitchell, 1973).. Visual performance also depends on retinal pooling - the summation of signals from individual sensory cells to produce a retina with fewer individual receptor units but greater sensitivity per receptor. With the longer focal length of its larger eye, an ...

1. The Order Cetacea contains from eighty to ninety known species, belonging to about forty-four genera and four families.. 2. Cetaceans are found in all seas from the Equator to within the Arctic and Antarctic Circles, and in some of the larger rivers (the Ganges, Brahmaputra, Indus, and Irawadi in the Old World, and the Amazon and La Plata in the New).. 3. The species of Oceanic Cetaceans are mostly very widely distributed, especially the Delphinidæ, but in some cases are local, some species being confined to the Arctic and Antarctic Seas respectively, and some being peculiar to the Pacific and to the North Atlantic.. 4. The Fluviatile Dolphins proper constitute a family of themselves (Platanistide) with a very singular distribution, one genus being restricted to the rivers of India, and two others to those of South America.. 5. Besides the Platanistidæ some of the Delphinidæ are found in rivers, such as Orcella fluminalis in the Irawadi, and Sotalia tucuxi (with perhaps others of the same ...

Holy, Trippel and Kings gillnets consist of a single wall of netting that is injected with barium sulphate, which makes the netting stiffer less likely to tightly tangle around a fin, flipper or tail. Barium sulphate also makes the nets more acoustically detectable for whales, dolphins and porpoises that are using echolocation to find objects. The ropes they use for float lines are specially designed to be easily broken (under a force of 1,100 lbs) so large cetaceans can wrestle their way free. In order to keep cetaceans away from the floatlines in the first place, the team designed a glowing rope that may visually deter the animals ...
The U.S. National Marine Fisheries Service has published for comment a draft national Procedural Directive clarifying the process for eligible permit applicants to obtain releasable marine mammals for public display purposes under the Marine Mammal Protection Act. Releasable marine mammals are those that were successfully rehabilitated by the Marine Mammal Health and Stranding Response Programs network of stranding centers and have been determined by the rehabilitation facilitys attending veterinarian to be candidates for return to the wild. NMFS will no longer grant permits for the specific purpose of retaining releasable marine mammals for public display. Instead, applicants will now need to apply for a permit to take (collect) animals from the wild pursuant to the MMPA. Non-releasable animals, on the other hand, may still be obtained through NMFS administrative procedures.. NMFS must receive any comments must by December 15, 2017..

As with all mammals, the marine mammals are characterized by the presence of hair and mammary glands, which in females produce milk for the nourishment of young. All are warm-blooded, breathe in air utilizing lungs, bear their young alive, and suckle them on their own milk. Some, such as the whales, have very limited hair, reducing drag in the water. Instead, they maintain internal temperatures with a thick layer of blubber (vascularized fat). However, the sea otter, unlike most marine mammals, has as a primary form of insulation an exceptionally thick coat of fur, the densest in the animal kingdom. Marine mammals are considered to have evolved from land dwelling ancestors and share several adaptive features for life at sea. These adaptations include generally large size, hydrodynamic body shapes, modified appendages, and various thermoregulatory adaptations. Different species are, however, adapted to marine life to varying degrees. The most fully adapted are the cetaceans and the sirenians, ...

The study is based on data gathered by the Kandalaksha State Sanctuary during 1947-1961. Most of the mammals were observed from islands during the navigational (free ice) period. It appears that the number of belugas that visit the gulf has greatly decreased. The greatest numbers of the mammals were observed in August-September -- a time when large concentrations of herring approach the coast. Usually, the number of belugas varies from year to year; the minimum was reached in 1948-1951 (5 in a year); the maxima in 1953 (37) and 1947 (32). (Author)(*CETACEA

MARINE MAMMALS. (plate VIII., p. 216). Section I.-Introductory Remarks Most of the recent writers on geographical distribution have confined their attention to terrestrial Mammals, or at any rate have but casually alluded to the marine groups of that Class. The seven previous chapters having been devoted to the terrestrial Mammals, it is proposed now to examine the principal facts connected with the distribution over the worlds surface of the Marine or aquatic members of the Class.. Aquatic Mammals which pass their lives entirely, or for the greater part, in the water are, of course, subject to very different laws of distribution from the terrestrial forms. As regards aquatic Mammals, land is of course an impassable barrier to their extension, and, subject to restrictions in certain cases, water offers them a free passage. Just the opposite is the case with the terrestrial Mammals, to which in most cases land offers a free passage, while seas and rivers restrain the extension of their ...
