The Nile crocodile is one of the largest predators in Africa. It lives in rivers, lakes, and swamps, where it hunts a wide variety of animals.
The Nile crocodile differs from other crocodiles with its very large size and bite force. It is important for nature because it regulates animal populations and eats sick and dead ones, helping to keep water bodies clean.
