Aside from humans, the crocodile does not have any natural enemies, according to All About Wildlife — an educational food web website for kids. The crocodile has a sturdy armor of bony plates that cover the majority of its body, and it has strong jaws that are capable of crushing everything from cast iron to bones.
While the crocodile does not have any natural enemies, it is a predator to many. Crocodiles hunt and eat a variety of animals, including fish, amphibians, turtles, birds and mammals. Basically, any animal that happens to cross the path of a crocodile can fall prey to its powerful jaws.
