Cassius, an Australian saltwater crocodile (Crocodylus porosus), is the largest crocodile in captivity at 5.48 m (17 ft 11.75 in). The Australian saltwater crocodile is the largest and most fearsome of today's species. Specimens can live for more than 100 years, can grow to 7 m (23 ft) and weigh more than 1 tonne (1.1 ton)!
Australian wildlife zoo Marineland Melanesia, on Green Island, currently has more than 50 crocodiles, from young creatures to more mature specimens such as Cassius. Cassius is aged about 100, is the largest crocodile that has ever been caught alive in Australia, and is thought to be a man-eater. He was brought about 3,200 km (1.988 miles) from Australia’s Northern Territory to Green Island in 1987, by truck.
