The thorny devil (Moloch horridus) is an Australian lizard, also known as the mountain devil, the thorny lizard, or the moloch. The thorny dragon grows up to 20 cm (7.9 in) in length, and can live for 15 to 20 years. An intimidating array of spikes covers the entire upper side of the body of the thorny dragon. These thorny scales also help to defend it from predators. The thorny dragon’s scales are ridged, enabling the animal to collect water from any part of its body by simply touching water, usually with their limbs; via the capillary principle water is transported to the mouth through their skin.
