The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats across sub-Saharan Africa and parts of Madagascar. It is the largest crocodile in Africa and among the largest living reptiles. Its global conservation status is listed as Least Concern.

Description

The Nile crocodile is a large crocodilian with a powerful tail, robust body, long snout, and strong jaws. It is one of the largest living reptiles and is especially known for its size and predatory strength. Adult Nile crocodiles can reach very large sizes, with some individuals rivaling the saltwater crocodile in length and mass.

Distribution and habitat

The species is found across much of sub-Saharan Africa and in Madagascar, living mainly in lakes, rivers, swamps, marshlands, and some brackish waters. It is closely associated with aquatic environments.

Diet and behaviour

Nile crocodiles are carnivorous and feed on fish, mammals, birds, reptiles, and carrion. They are ambush predators that often hunt from the water.

Conservation status

The Nile crocodile is listed as Least Concern and is generally considered stable overall. Some local populations have faced pressure from hunting, habitat loss, and pollution.
