American crocodiles have adapted to eating a wide variety of foods. They are gray-green in color, which allows them to blend into the brackish waters they inhabit. They hunt by lying motionless until prey comes along, usually fish, crustaceans or turtles. They attack their prey with a sudden ambush followed by a "death roll," in which they roll in the water until the prey dies. Crocodiles have also learned to regurgitate bits of food to attract more prey. Nonetheless, their cold-blooded metabolism allows them to survive for long periods between feedings.
