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, is home to many crocodiles, from young creatures to more mature specimens such as Cassius. Cassius, who is thought to be as old as 120, is the largest crocodile that has ever been caught alive in Australia. He was brought about 3,200 km (1.988 miles) from Australia’s Northern Territory to Green Island in 1987, by truck.
