The warus Odobenus rosmarus
is the only member of its family and is very easily identified. Like seals, walruses have both pectoral flippers and tail flippers as well as a muzzle with long whiskers. The walrus differs by having a broad muzzle with the whiskers on the front end, and by having two large tusks up to 1 m in length. The walrus is a large and bulky species reaching up to 3.6 m in length. Its skin is notably thick, rough and creased. It has small 'bloodshot' eyes. The tail end is enclosed in a web of skin. Most walruses are grey to cinnamon-brown in colour, becoming paler with age. The skin becomes flushed with blood when warm and they acquire a rosy red colouration.
