A crocodile will eat almost anything that moves. Hatchlings and young crocodiles eat small fish, snails, crustaceans, and insects. Adults feed mostly at night on fish, crabs, turtles, snakes, and small mammals. The growth rate of crocodiles varies with food availability and temperature. Digestion is efficient only within a certain range of body temperatures.
