The saltwater crocodile is a fierce and dangerous predator, and have claimed more human lives than sharks. They are found not only inland in freshwater, but also in the sea off Australia�s north coast. It grows to �only� 6 metres (20 ft). That�s plenty enough to grab a unwary human by the legs and spoil their day with the �death-roll� they use to disable and eventually kill their victims. They are �lovingly� called by Australians with the pet name of �saltie� for obvious reasons.
