Rex is the HUGE 5 metre Saltwater Crocodile - one of the biggest in the world, in fact - who lives here at WILD LIFE Sydney Zoo on Darling Harbour.
The terrifying Saltwater Crocodile is an amazing creature. It's the largest reptile in the world, measuring over six metres from tip to tail and weighing up to a mind-boggling 1200 kilograms. Our saltwater croc Rex is one of the bigger ones at over five metres long!
Saltwater crocs (or 'salties') are also known as Estuarine Crocodiles or Indopacific Crocodiles because they can live happily in both salt water and fresh water environments.
The crocodile is a patient, clever hunter, waiting by the riverbank with only its nostrils and eyes above the water, ready to pounce on anything unlucky enough to come close! Their green-grey colour means they are perfectly camouflaged under the water, and they can hold their breath for over two hours!
They can feast on anything including cattle and water buffalo, grasping them with their fearsome teeth and performing the incredible 'death roll', where they spins their bodies around to drown their prey and twist pieces off, ready to be devoured.
