The saltwater crocodile is the largest of all living reptiles, as well as the largest terrestrial and riparian predator in the world. The males of this species can reach sizes of up to 6.7 m (22 ft) and weigh as much as 2,000 kg (4,400 lb).
Females are much smaller and often are not longer than 3 m (9.8 ft). As its name implies, this crocodile can live in salt water, but usually resides in mangrove swamps, lagoons and lower stretches of rivers. They have the broadest distribution of any modern crocodile, ranging from the eastern coast of India, throughout most of Southeast Asia, stretching south to northern Australia.
