The teeth of crocodiles grow only in the mandibular alveoli of crocodiles, which are very similar to mammals. Crocodile eyes grow on the top of the head, in addition to the eyelids, there is a transparent nictitating membrane, can be well adapted to the water environment. The crocodile's nostrils are on the back of the upper end, and the valve is automatically closed when diving, which is a good way to prevent water from entering the nostrils.

However, it acts as a balance when crawling.
The tail of a crocodile can be used as a weapon to help itself prey. For example, when a crocodile sees an animal drinking by the river, it sweeps across it with its strong tail and makes the animal fall into the water, which naturally becomes a delicacy in their mouth.
