Description

The threetooth hagfish is a hagfish (Myxinidae) of soft bottoms of the continental slope in the southwestern Atlantic. The species grows to about 40 cm and has a jawless, eel-like, pale body without true fins, with barbels around the mouth opening and rows of slime pores. As a scavenger and bottom-dweller it bores into dead and dying animals; when threatened it secretes large amounts of slime. The fish is harmless to humans.
