Australia’s thorny devils (Moloch horridus) are incredible animals. Their spiky armour is, as you might have guessed, used for defence. Their is dotted with tiny grooves that suck up dew on the surface and water from the ground through capillary action, passing it to the devil’s mouth without the lizard having to lift a finger. So it’s probably not a look judgement this little devil has on its face, rather, it’s one of satisfaction.
