Facts about this animal
The walrus is a very large and robust pinniped, with a brown skin. The skin is covered with short coarse hair. The walrus' most distinctive features are the large tusks (enlarged upper canine teeth up to 1.5m). The Atlantic subspecies O.r.rosmarus measures about 300 cm and weigh 1'200 kg. Females measure 250 cm and weigh 750 kg. The Pacific walrus O.r.divergens is slightly larger. The walrus is a social animal, forming mixed herds of up to 2'000 of more during feeding and migration. In breeding time older males defend harems. They feed on molluscs and crustaceans.
Did you know?
that walruses use their whiskers (vibrissae) to locate food?. A walrus has about 400-700 vibrissae on its snout. These are attached to muscles and are supplied with blood and nerves. A walrus moves its snout through bottom sediment to find food.

Why do zoos keep this animal
Zoos keep walruses primarily for educational purposes to demonstrate how the carnivores adapted to arctic and maritime conditions and thus became able to expand their range into the seas and the north polar zone. Of course the walrus is also an excellent ambassador for its ecosystem and may serve as a flagship species for campaigns or educational programmes raising awareness about Global Warming.
