The visual system of aquatic mammals is of special interest because of its mostly amphibious mode of action. Although truely aquatic mammals (cetaceans, sirenians) spend their entire lives in water, their aerial mode of breathing confines them to the superficial water layer. Semiaquatic mammals (pinnipeds) spend a significant proportion of time on land.

Immunoglobulin Classes in Aquatic Mammals
The Journal of Immunology, 1971Abstract On the basis of serologic cross-reactivity, three immunoglobulin classes homologous to human IgG, IgM and IgA were identified in two species of acquatic mammal representing the orders Cetacea (dolphin) and Pinnipedea (sea lion).

Virtually all mammals can swim at least sufficiently well to cross bodies of water, but the extent of specific adaptation for aquatic life varies amongst different mammals from no more than modified behaviour like the Japanese macaque monkeys spending their days sitting in hot springs, through different degrees of amphibiousness to the permanently ...

Demonstration of free fatty acids in the integument of semi-aquatic and aquatic mammals
Acta Histochemica, 2012The sensitive red fluorescence dye BODIPY® 665/676, and embedding in the water-soluble resin Technovit® 7100 were used to demonstrate free fatty acids in the epidermis of seven semi-aquatic and aquatic mammalian species with a sparse or dense hair coat.

1989
Cold water has been described as the harshest thermal environment encountered by mammals anywhere on earth (Irving 1973). This is a perception undoubtedly reinforced by our own limited thermoregulatory competence in the aquatic medium. In 0°C water, the rectal body temperature (Tb) of an adult human may drop at a rate of 0.07–0.08°C min-1, resulting in

Method for communicating with aquatic mammals
The Journal of the Acoustical Society of America, 1982A phonetic alphabet for communicating with dolphins, porpoises and whales includes three basic geometric shapes, various combinations of which are used to represent speech sounds. The alphabet consists of eighteen symbols which may be understood by animals trained to identify these symbols with words by using their innate echolocation sensory ...

Somatic Sense in Aquatic Mammals
2001Somatic sense in cetaceans did not attract as much attention of investigators as the auditory and visual ones. So available data in this field are restricted. Morphological studies have shown the presence of both incapsulated and free nerve endings in the dolphin’s skin, especially numerous at the head and snout, around the blowhole, and around the ...

The aquatic mammals and reptiles of the Amazon
1984The vast river systems, flooded forests and floodplains of the Amazon have provided the necessary ecological conditions for the evolution of an interesting and extremely diverse aquatic fauna. The magnitude of which is implied by the 2000 fish species (Roberts 1972).

Nematodes Transmitted to Man by Fish and Aquatic Mammals
Journal of Wildlife Diseases, 1970Zoonotic nematodes may cause disease in man through migrating larva (larva migrans), through direct infection or possibly through allergic responses. The parasitic genera Ancylostoma, Uncinaria, Bunostomum and Toxocara can cause larva migrans. The cod worm (Phocanema decipiens) a parasite found in fish and seals, can infect man, as can Anisakis ...
