The walrus is a marine mammal (Odobenus rosmarus) that is found in arctic seas. Largest of the fin-footed mammals, it has long tusks, light-brown wrinkled hide, and bristly cheek pads. An adult male may weigh up to 3,000 pounds (1,400 kilograms). Walruses live on beaches near shallow water in herds of about a hundred animals and eat mainly shellfish. Hunted for blubber, hides, and ivory, they are now endangered.
