How Do Crocodiles Eat?

Crocodiles are strictly meat eaters. In the wild, they prefer fish, birds, frogs and crustaceans, but they’re not dainty diners: They grab the prey and crush it with massive jaws, then swallow the meal whole. They’re unable to break off small pieces or chew.

Because of this, a crocodile's digestion requires some help. So a croc will also routinely swallow small stones in order to grind up the food that is sitting in the stomach like a brick. Crocodiles can live for months without eating, due to their slow metabolisms.

Down the hatch, all in one piece:

  • Snakes swallow their prey whole because they don't have teeth for chewing.

  • Some birds, such as ducks, also swallow everything whole. They also gulp down stones to grind up the food.

  • Frogs have no teeth, so they swallow insects whole. Most lizards are also toothless, so they crush their meals to death before downing them.
