"One of Australia’s more bizarre creatures is the thorny devil or dragon, also known as the moloch. The devil is named for the ancient god Moloch, a hideous demon smeared with the blood of child sacrifice, but in reality, she is five inches long and lives entirely on ants. The thorny devil is, of course, covered in fearsome thorns, presumably to warn off would-be predators, but the spiky scales also serve another ingenious function. They form an incredibly efficient water harvesting system. What can the thorny devil teach us about water management in our own increasingly parched world?"
