The largest species of crocodilian in the world is the estuarine or saltwater crocodile (Crocodylus porosus), which ranges throughout the tropical regions of Asia and the Pacific, including the northern coast of Australia. Average adult sizes for male and female C. porosus are 4.6–5.2 metres (15–17 feet) and 3.1–3.4 metres (10 feet 2 inches–11 feet 1 inch), respectively, with outsize males occasionally achieving 6 metres (19 feet 8 inches) or, on rare occasions, even 7 metres (22 feet 11 inches). One of these really large males may weigh as much as 1,000–1,200 kilograms (2,204–2,645 pounds), also making these animals the heaviest reptiles.

The largest crocodile in captivity ever was a 6.17-m (20-ft 2.91-in) saltwater crocodile captured on 3 September 2011 in Bunawan, in the province of Agusan del Sur, Mindanao, Philippines. The crocodile was named Lolong and housed in a custom-built enclosure at Bunawan Eco-Park and Research Centre, Philippines. Lolong was weighed in at a truck weigh-bridge and verified as approximately 1,075 kg (2,370 lb). Lolong died on 10 February 2013.
