Its skin is highly wrinkled and thick, up to 10cm (4in) around the neck and shoulders of males. Walruses have young fairly infrequently, so it is vital for them to protect their offspring. Walruses are sexually dimorphic. The skin of males often has large nodules; these are absent in females. The walrus is able to dive to depths of over 300 feet because of special adaptions that conserve oxygen. Physical Characteristics: The walrus is a large pinniped; seals and sea lions are also pinnipeds. Skin and bone are used in some ceremonies, and the animal appears frequently in legends. Females in estrus will gather in groups on the beach, and males will stake out territories on the coastline and try to attract them.

Walruses have super sensitive whiskers, which help them detect food at the bottom of the ocean. [95] The sustainability of these levels of harvest is difficult to determine given uncertain population estimates and parameters such as fecundity and mortality. Walruses maintain such a high body weight because of the blubber stored underneath their skin. Calves shed a fine prenatal coat, called lanugo, about two to three months before they are born. It is shortest on the face and absent on the flippers. Most pinnipeds cruise at speeds around 5 to 15 knots, though sea lions sometimes reach bursts up . The males possess a large baculum (penis bone), up to 63cm (25in) in length, the largest of any land mammal, both in absolute size and relative to body size. Walruses can be found in the icy oceans of the North Pole at the top of the world, in places like Canada, Alaska, Russia, Greenland and Scandinavia.
