The deepwater arrowtooth eel has a typical eel shape but with a long pointed snout, and a dorsal fin which starts above the pectoral fin and an anal fin beginning about halfway along the body. There are many rows of small teeth in the jaws and on the roof of the large mouth. The gill apertures are horizontal and almost meet beneath the throat, hence the name cutthroat eel.
