I was first made aware of the Frilled Lizard in the animated movie “The Rescuers Down Under.” They made him such a cute character. But now for the facts.
The frilled lizard is also called the frilled neck lizard and the frilled dragon. His frill is activated by the lizard when frightened as he opens his mouth wide. As part of the bluff the lizard may hiss and jump towards the threat. The lizard prefers to run rather than fight and runs on its hind legs to the nearest tree which it rapidly climbs.
Until 1991, a frill-necked lizard was featured on the reverse of the Australian 2 cent coin.
