Biological Difference

The salt glands of gators are not as good as of crocs so they prefer to live in lakes instead of salty waters.

There are numerous little holes on the body of a crocodile. These small ditches are quite special since they are sense pressure receptors that make out any possible movement in water made by an animal. The entire body of crocs is masked with these small ditches.

In gators, only jaws of the animal have these small receptors.
