Slime killer hagfish feasts in rotten flesh

 Hagfish are partway between fish and worms, with a spinal cord but no backbone. They resemble the common ancestor of all backboned animals, and have changed little in at least 300 million years. This is how it would eat you  "After you're dead it will drag you out of your burrow and devour you. But it's unlikely anyone will try to devour it in turn, because that slime it used to kill you also protects it from predators. Besides, why would anyone want to eat a creature that regularly eats decaying corpses from the inside out?" This creature is truly a beast from another world for me it would be a great monster for a movie.Long thought to be scavengers, they have now been seen actively hunting for the first time. Vincent Zintzen of the Museum of New Zealand in Wellington and colleagues used underwater video cameras to catch them in action. The researchers saw that the fish released a lot of slime and they found out that it could be used for shark repellant. This scary creatures have evolved to be one of the best prepared animals in the world.
