A walrus eats mainly mollusks, such as clams. A walrus also eats shrimp, crab, worms, sea cucumbers and coral. Occasionally, a walrus has been known to eat the carcasses of seals when it cannot find food.
Because of their extremely large size, walruses eat a great deal of food. Adults commonly consume 3,000 to 6,000 clams in a single feeding.
