The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries. The largest species of crocodilian in Africa, it can grow to be six metres long and can weigh over 700kg. Nile crocodiles are found anywhere with a water source. It likes rivers, lakes, marshes, streams, swamps and dams – including the Nile river. It can swim underwater for 30 minutes before needing fresh oxygen, and can remain stock-still underwater for up to two hours at a time. This helps it lie in wait for prey.
