Saltwater Crocodileイリエワニ

Crocodylus porosusLC— Least Concern

The saltwater crocodile is the largest living reptile, ranging from India's east coast across Southeast Asia to northern Australia and occasionally straying as far as southern Japan. Powerful swimmers that use ocean currents to travel long distances between rivers and islands, they possess the strongest bite force ever measured in a living animal and prey on an unusually broad range of species, from fish and birds to large mammals. Despite their fearsome reputation, populations in Australia have rebounded strongly since hunting bans in the 1970s, and the species is currently listed as Least Concern by the IUCN.
