Sharks are amazing hunters but even they are no match for the mucus spitting hag fish. Hag fish have mucus-secreting glands all over their bodies. They use these glands to ward off enemies. The ecologist Vincent Zintzen viewed 500 hours of film watching the hag fish encounter their enemies such as seal sharks or the conger eel. Of all 14 encounters the hag fish came out victorious and the enemy fled the scene. Not only can they defend them selves thy can go on the hunt to. Vincent saw in amazement as the hag fish chased down a 6 inch long fish into a hole, the hag fish twisted itself into a not for leverage then pulled the fish out of the hole.
I wonder what they eat mostly. I wonder where you can find these fish.
