Description

The black hagfish is a jawless, eel-shaped fish of the hagfish family (Myxinidae) from the north-eastern Pacific. The species grows to about 64 cm and has a naked, dark, snake-like body without jaws, gill covers or true fins, with barbels around the mouth opening. It lives on mud bottoms from about 100 metres into the deep sea. Hagfishes are notorious scavengers that bore into dead or dying animals; when disturbed they secrete, within seconds, enormous amounts of tough, suffocating slime as a defence. It feeds on carrion and small bottom animals. The species is harmless to humans.
