Food Preferences And Resources. 1  Walruses prefer molluscs - mainly bivalves such as clams. They also eat many other kinds of benthic invertebrates including worms, gastropods, cephalopods, crustaceans, sea cucumbers, and other soft-bodied animals. 2  Walruses may eat the carcasses of young seals when food is scarce.
Belugas eat a large variety of fish and crustacean species, including salmon, smelt, herring, Arctic and polar cod, shrimp, crabs, mollusks, and marine worms. They feed in both shallow and deep water areas, in both open water and bottom habitats. They have been recorded diving to more than 350 metres to feed.
