Walrus (Odobenus rosmarus)

Did you know?

That Walruses use their whiskers (vibrissae) to find food? A walrus has about 400-700 vibrissae on the snout. These are subject to the muscles and are irrigated by the blood and nerves. A walrus moves its snout through bottom sediments for food.

The walrus is very large and robust, with a brown skin. The skin is covered with short coarse hair. The most distinctive features of the walrus tusks are large (enlarged upper canine teeth up to 1.5 m). Orrosmarus Atlantic subspecies are about 300 cm and weigh about 1,200 kg. Females are 250 cm and weigh 750 kg. The Pacific walrus Ordivergens is a little bigger. The walrus is a social animal, forming mixed groups of up to 2,000 or more during feeding and migration. During the breeding season, males defend larger harems. They feed on mollusks and crustaceans.
