World's Largest Living Reptile

The saltwater or estuarine crocodile lives in northern Australia and tropical coastal waters across parts of the Indian and Pacific Oceans, using estuaries, rivers and brackish or saline habitats.

The species shows pronounced sexual size differences. Males are much larger; Queensland Museum describes females as typically around 3 metres long and up to 150 kilograms.

Its broad snout, muscular tail and protective bony back plates are characteristic crocodilian features. It is substantially larger than Australia's freshwater crocodile.
