Each sea turtle species feeds on a specific diet and all lack teeth. Loggerheads feed mainly on hard-shelled organisms such as lobsters, crustaceans, and fish. Green turtles are vegetarian and prefer sea grasses, while leatherbacks feed mostly on jellyfish. Hawksbills have a bird-like beak that is used to cut through soft coral, anemones and sea sponges. Olive ridleys are omnivorous, mostly eating jellyfish, snails, crabs, and shrimp but they will occasionally eat algae and seaweed as well.
