Perentie

The perentie (or perente) (Varanus giganteus) is the largest monitor lizard or goanna native to Australia, and the fourth-largest living lizard on earth, after the Komodo dragon, Asian water monitor, and the crocodile monitor. Found west of the Great Dividing Range in the arid areas of Australia, they are not a common sight because of their shyness and the remoteness of much of their range from human habitation.

Their status in many Aboriginal cultures is evident in the totemic relationships, and part of the Ngiṉṯaka dreaming, as well as bush tucker. They were a favoured food item among desert Aboriginal tribes, and the fat was used for medicinal and ceremonial purposes.
