The Thorny Devil Lizard
The thorny devil lizard looks like a tiny spiny dinosaur, but these spines are actually camouflage them in their environments. Their coloration helps them blend in, too, especially amongst the scrub of the grasslands and in the Australian deserts. They mainly eat ants, but the other amazing thing about their spines is that they also store water in them. This is very useful in the desert, where water is scarce. Having these spines means that they can go for much longer in the hot sun without taking a drink.
