Distribution and habitat
It is found off Southern California, Peru, and Chile in marine bathydemersal habitats approximately 700 metres (2,300 ft) to 1,860 metres (6,100 ft) deep.[2]
Anatomy and appearance
It grows to 65 centimetres (26 in) total length and is similar in appearance to other hagfish.[2] Gonads are situated in the peritoneal cavity.[2]
