The Devil's Coach-horse is a special member of the Rove Beetle family (of which there are hundreds of members). This one is huge (up to 3cm long) and curls up its abdomen like a scorpion, although this is only a defence posture. It can also emit could smelling fluids from its mouth and abdomen tip, and give you a nasty bite! It is a fast and ferocious predator, hunting other invertebrates. The name comes from folk lore, as it's long been associated with the devil.
