And then I stopped my entire work day for this…

Ancient flesh-eating ‘penis worm’ dragged itself around by teeth

It sounds like something out of a Frank Herbert fantasy novel, but flesh-eating ‘penis worms’ roamed the Earth 500 million years ago.

The creature was able to turn its mouth inside out and use its tooth-lined throat – which resembled a cheese grater – to drag itself around the Cambrian world.

Unlike the monsters in Herbert’s novel Dune, these creatures were only the size of a finger, and lived in burrows under the sea.

However they were voracious predators, gobbling up anything that crossed their path, including worms, shrimp and other marine creatures.
