Description

The southern hagfish is a hagfish (Myxinidae), a jawless, primitive fish from the waters around southern South America. The species has an eel-shaped, scaleless body without true jaws, with barbels and rasping horny teeth around the mouth. When disturbed it secretes enormous amounts of sticky slime as a defence. It lives bottom-bound on muddy bottoms, where it often buries itself. It feeds by scavenging on dead and dying animals. The species is harmless to humans.
