The Australian freshwater crocodile is a small reptile with a very narrow snout. It lives in rivers, lakes and swamps in northern Australia and rarely attacks people.
The Australian freshwater crocodile differs from the saltwater crocodile by its smaller size, narrow snout and peaceful nature. It regulates the number of fish and other animals in freshwater bodies and serves as an important part of the natural food chain.
