What is the class of the Thorny devil?

Thorny devils are Australian reptiles. Specifically, they are lizards specially adapted to live in dry conditions. The upper part of their bodies are covered with sharp spikes which serve two functions: defence, and to channel all moisture towards their mouth.

The Thorny Devil lives in the desert and semi-arid outback regions of Australia. Also sometimes known as the Moloch, it is mostly found in the western two-thirds of the continent, through Western Australia, the Northern Territory and South Australia.
