Southern elephant seals feed exclusively when they are at sea. For this reason not much is known about what they eat. The main known sources of food are squid, crabs, shrimp, fish, and sharks. This prey is obtained both near the surface and also during very deep dives. They have been known to eat bottom dwelling fish.
