The Thorny Dragon

The thorn y dragon, also known as the thorny devil, is an Australian lizard. It's scientific name is Moloch horridus but it is also called the mountain devil, the thorny lizard or the moloch. The thorny dragon grows up to 20 cm in length and can live up to 20 years. It is a brown animal but it's colours vary on the temperature (pale when hot, darker when colder).

This animal has a false head on his neck to distract his predators. He simply puts his head down exposing the false head as the real one and he then lets the predator fight it out with his false head. The thorny devil is covered in spikes which are used to camouflage, collect water and hurt predators. The Thorny Dragon's name comes from his two large horned scales on his forehead, making him look like a dragon. 

The mountain devil lives in central Australia and primarily in arid areas or deserts. 

It mainly eats ants and other insects and can eat thousands of ants per day. The scales on his back allow him to absorb water throughout his body.
