The saltwater crocodile (Crocodylus porosus), also known as the estuarine crocodile, Indo-Pacific crocodile, marine crocodile, sea-going crocodile or informally as saltie, is the largest of all living reptiles, as well as the largest terrestrial and riparian predator in the world. Males of this species can reach sizes up to 6.3 m (20.7 ft) and weigh up to 1,360 kg (3,000 lb). However, an adult male saltwater crocodile is generally between 4.3 and 5.2 m (14 and 17 ft) in length and weighs 400 to 1,000 kg (880–2,200 lb), rarely growing larger. Females are much smaller and often do not surpass 3 m (9.8 ft). As its name implies, this species of crocodile can live in salt water, but usually resides in mangrove swamps, estuaries, deltas, 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, and northern Australia.
