The Mugger Crocodile (Crocodylus palustris) listed as vulnerable on the IUCN Red list is one of the two species of Crocodiles found in Sri Lanka, the other being the Saltwater Crocodile. The adult Mugger Crocodile is blackish grey in colour with a broad elongated snout, the male growing to about 10 feet and weighing over 1000 pounds. It inhabits fresh water habitats such as lakes, ponds, tanks, rivers, swamps and marshes. Being a skilled predator, it waits in ambush for its kill which is mainly fish, reptiles, birds and mammals and in some cases humans too. A recent survey shows that the biggest population of Mugger Crocodile in the world, amounting to over 500 is found in the Yala National Park in Sri Lanka.
