The crocodile (鳄鱼) only lives in hot countries, such as India, Australia,,Africa and America. It spends most of its time lying in the mud or rivers. It lays its eggs and leaves them under leaves or sand, and the baby crocodile come out of the shells. The crocodiles long tail helps it to swim . It is also an excellent weapon (武器). One blow will knock down a man or even a big animal at once.

The crocodiles protects itself by the hard body plates. And those plates cover most of its body. Because of its special neck, the crocodile cannot turn its head around ; instead it can only see in front of itself. The crocodile bird helps to clean the crocodiles teeth. For it cannot clean its own teeth, nor can it move its tongue up and down . With its terrible teeth, it seizes its food, such as a fish, a duck, or even a careless man, and then it holds them below the water until they drown (淹死)。
