Saltwater Crocodile Crocodylus porosus

The Saltwater Crocodile, also called the Estuarine, lives mainly in freshwater rivers and swamps, but is at home in brakish estuary waters, coasts and has even been recorded kilometres out to sea with barnacles on its scales.

Native to northern Australia, much of Southeast Asia and eastern India, it is the world's largest living reptile and largest land predator. The formidable predator can jump vertically out of the water. Large males can grow to over 6 metres (over 20 ft) long and weigh over a tonne. The Saltwater Crocodile holds the record for the greatest bite force of living animals at c.3700 psi.

Juveniles. Its lifespan can be in excess of 70 years. Adult colour is grey with pebbled dark and light scales, a light underside and a broad snout (for a crocodile) - not to be confused with Australia's smaller Freshwater Crocodile which is plain brown and has a slender snout. Diet is diverse, including any fish (marine or freshwater), invertebrate, bird, reptile/amphibian or mammal (including humans and even gaur). Threats include hunting by humans for skins and habit loss.
