Food Preference & Resources
As a group, sharks and batoids eat almost anything: fishes, crustaceans, molluscs, marine mammals, and other sharks.
While some sharks are probably not very selective feeders, certain sharks eat some foods more than others. For example, hammerhead sharks (Sphyrna spp.) are known for eating stingrays; bull sharks eat other sharks; and smooth dogfish (Mustelus spp.) eat crabs and lobsters.
Just about any animal in the ocean can be a meal to a shark. Great whites prey on California sea lions, wobbegongs eat shrimp, and tiger sharks feed on several species of sea turtles.
Tiger sharks have been called "garbage cans of the sea" because they feed opportunistically on both live food and carrion. Prey includes bony fishes, other sharks, marine mammals, seabirds, and invertebrates. Tiger sharks are ecologically important predators of sea turtles and snakes.
