Mammals walrus

The males of some mammal species have a bone called the baculum within the penis. Also called the penis bone, penile bone, or os penis, it is an aid to copulation and its size and shape are specific to each species. Animals that have such a bone include rats, dogs, and walruses. These bones are used as fertility charms and objects of curiosity. [Pg.135]

Lipids from marine mammals such as seal, whale, and walrus are primarily stored as subcutaneous fat or blubber. Seal blubber comprises 29% of the carcass... [Pg.1619]

The aquatic mammals of the coasts are carnivores that belong to the suborder Pinnipedia. Members of this suborder, commonly referred to as the pinnipeds, or fin-footed animals, use flippers for locomotion on land and in the water. Their sizes range tremendously, from relatively small animals that weigh a mere 200 pounds (90.7 kg) to organisms that are as heavy as several tons. Pinnipedia can be divided into three main families Phociadae (true seals), Otariidae (eared seals, which includes sea lions and fur seals), and Odobenidae (walruses). [Pg.108]

Subsistence Hunters. Native American populations, such as the Inuit of Alaska and other subsistence hunters (particularly those living in high latitude areas of the United States), may be exposed to mercury in wild game (e.g., seals, narwhal, walrus, and other game species or marine mammals). [Pg.518]

The effects of oil spills on marine and other aquatic mammals vary with species. Seals, sea lions, walruses, whales, dolphins, and porpoises are discussed here, as well as the effects on polar bears and otters. Although these two species are not actually marine mammals, they spend much of their time in or near the water. All of these animals are highly visible and cause much public concern when oiled. [Pg.206]

SCCP has so far been found in arctic whales, seals, walruses [51] and two species of Arctic birds (Little auk, Alle alle and Kittiwake, Rissa tridactyla) [52]. Thus, SCCPs have been measured in animal species living in remote areas . The following also shows that these concentrations are similar to concentrations of well-recognised POPs such as PCB, DDT and toxaphene [53]. More detailed comparisons of POP concentrations for the arctic marine mammals and for the bird Kittiwake (Rissa tridactyla) are presented in Table 17 and Table 18, respectively. [Pg.32]

Only one group of mammals does not produce lactose in their milk, the Pinnipedia, a group that includes seals, sea lions, and walruses. [Pg.399]

Pinnipedia are carnivorous and are admirably adapted to marine life in cold or icy water, but they rarely move away from the coast and spend part of their life ashore. These mammals are also well known, and their main representatives are seals Monachus, Phoca), otaries (Arctocephalus, Callorhinus, Eumetopias, Otaria, Zalo-phus), the sea elephant (Mirounga) and the walrus (Odobenus). [Pg.900]
