The walrus has a serious personality. They're huge, massive animals- even polar bears find it difficult to harm one. They eat molluscs and fish, and they live in the Arctic.
Male AND female walruses have tusks. They use these to fight as well as to crack holes in the ice to breathe through (when they are under water).
Walruses spend most of their time swimming from place to place in large herds, migrating to wherever the most food can be found. Since they have an air sac in their throat they can buoy themselves in the water, and they have almost no hair on them.
