The crocodilians are repitles with four legs, very similar to the lizards. They are rather large and on their back, running from the neck to the tail, we can see bony ridges. Still, they are better known for their aggresiveness, and in the case of the larger species, for the threat they can be to human beings.

These reptiles remain in the water most of the time. They are capable of opening their mouth and swallow underwater without drowning. Caimans, alligators and gavials inhabit fresh water. The crocodiles can be founded on both, fresh and salt water. The caimans and alligators are aggresive but the crocodiles are super aggressive. While the gavials are totally harmless.
