Rankinia adelaidensis is a species of Heath Dragon, small Agamid reptiles, occurring in southern regions of Australia. These dragons are pale in colour, usually grey-brown, although males develop a reddish hue in the breeding season. They are timid in their behaviour, and will only briefly break from the cover of vegetation. They have a burrowing behaviour that is unique in Australian dragons, they will cover all but their snouts with a shuffling action, burying themselves in the sand. This behaviour may help the dragons to regulate their temperature.
