Walrus: Odobenidae

Walruses eat primarily bivalve mollusks, clams and mussels. They also feed on marine worms, crabs, shrimp, octopus, squid, and sea cucumbers. They occasionally eat fish and seals, including spotted, ringed, and bearded seals. The walrus squirts the muddy sediments on the ocean floor with water from its mouth, exposing the mollusks. Then it sucks the meat out of the shell. An adult walrus consumes about 4 to 6 percent of its total body weight daily. It can eat 3,000 to 6,000 clams per meal.
