Hag capisco, hagfish, hagfishes, or slime hags are a group of marine animals that belong to the class Myxini. Hag capiscos are also known as slime hags due to their slimy skin and haggard-looking appearance.
They have been around for more than 300 million years and can be found in all oceans but mostly near the bottom of the ocean floor where they prey on small invertebrates such as shrimp, krill, crabs, and starfish.
Hagfish are long and eel-like, but with a skull, unlike most other vertebrates. Their mouths have no jaws or teeth, but hagfish do have four pairs of horny plates that cover their gills instead of having individual gill flaps on each side as fish usually do. Hagfish also lack scales.
The skin is slimy since it contains very little in the way of connective tissue so hagfish can slip out of an angler’s grasp easily when handled by one hand.
