Crocodiles are carnivores, which mean they eat only meat. In the wild, they feast on fish, birds, frogs and crustaceans. At the zoo, they eat small animals that have already been killed for them, such as rats, fish or mice. They also eat live locusts.
In the wild, crocodiles will clamp down on their prey with their massive jaws, crush it, and then they will swallow the prey whole. They do not have the capability to chew or break off small pieces of food like other animals.
