The Frilled Lizard inhabits humid forests of northern Australia and southern New Guinea. He is characterised by the large ruff of skin that normally lies flat about his neck. This frill is supported by cartilage which allow him to erect it when he feels threatened or wishes to impress a female lizard. He leads an arboreal existence, feeding on beetles and termites, with a preference for moths and butterflies. His colouration varies based on his environment, with the mottled and cryptic blends of brown, black and grey allowing him greater camouflage.
