Reptiles of Australia's tropical savannas

Frill-necked lizard

The frill-necked lizard is a tree-dweller that lives in the tropical savannas


Northern Australia, like Australia generally, has a great diversity of reptiles. These include the largest reptile in the world, the saltwater crocodile, the well-known frill-necked lizard and some of Australia's largest and most venemous snakes.

Because reptiles are "cold-blooded" they do not need to maintain a constant body temperature like mammals and birds, which means when food is in short supply they can reduce their food intake to quite low levels. This allows reptiles to thrive in northern Australia's very variable climate with its long dry season.
