The saltwater crocodile (*Crocodylus porosus*) is the largest living reptile and a powerful apex predator native to brackish and freshwater habitats across South and Southeast Asia, northern Australia, and parts of the western Pacific. It is known for its wide range, powerful bite, and ability to move between river, estuary, and coastal environments.

Taxonomy and naming

The saltwater crocodile is the common name for *Crocodylus porosus*. It is also known as the estuarine crocodile and, in Australia, the saltie.

Physical characteristics

This species is the largest living reptile. Adult males commonly reach about 5 m in length, with some large individuals exceeding 6 m. Very large reports approach 7 m. Females are much smaller.

Distribution and habitat

Saltwater crocodiles occur from eastern India and Sri Lanka across Southeast Asia to northern Australia and islands in the western Pacific. They inhabit mangroves, estuaries, coastal marshes, rivers, lagoons, and other brackish or freshwater habitats.

Behaviour and ecology

The saltwater crocodile is a powerful apex predator and is capable of living in both saltwater and freshwater environments. It can travel long distances across open water and has salt-excreting glands that aid marine tolerance.

Conservation

The saltwater crocodile is currently considered Least Concern on the IUCN Red List. Historically, hunting and habitat change have affected local populations, and conservation status varies by country and region.
