Most turtles are omnivores; they eat a variety of different things, depending on their species. Musk turtles eat mollusks, plants, small fish and insects. The cooter turtle is mostly vegetarian, and the green sea turtle only eats grasses and algae.
The alligator snapping turtle lures in fish with its tongue, which looks like a worm. It wiggles its tongue to attract a hungry fish and then snaps down on it with its strong jaw. It also eats aquatic plants, snakes, frogs, fish, worms, clams, crayfish and other turtles.
