Crocodiles

By Liam.P

Diet

The diet of a crocodile changes over its lifetime. When it is a hatchling it eats frogs, tadpoles, shrimps, prawns, crabs and insects. As the crocodile starts to get older they begin to hunt larger prey. Like wading birds, freshwater turtles, file snakes, mudcrabs, fish and water rats.
