The saltwater crocodile (Crocodylus porosus), also known as the estuarine crocodile, Indo-Pacific crocodile, marine crocodile, sea crocodile or informally as saltie, is the largest of all living reptiles, as well as the largest riparian predator in the world.
Males of this species can reach sizes up to at least 6.30 m (20.7 ft) and possibly up to 7.0 m (23.0 ft) in length. However, an adult male saltwater crocodile rarely reaches or exceeds a size of 6 m (19.7 ft) weighing 1,000 to 1,200 kg (2,200–2,600 lb). Females are much smaller and often do not surpass 3 m (9.8 ft).
