Description

The inshore hagfish is a hagfish (Myxinidae), a jawless, primitive fish from the northwestern Pacific. The species has an eel-shaped, scaleless body without true jaws; around the mouth opening are barbels and rasping horny teeth. When disturbed it secretes enormous amounts of sticky slime as a defence. It lives on muddy bottoms of the sublittoral zone, where it often buries itself. It is a scavenger that feeds on dead and dying fishes and other animals. The species is harmless to humans.
