Myxine circifrons, the whiteface hagfish, is a marine bathydemersal species of fish in the family Myxinidae. It is found off Southern California, Peru, and Chile and grows to 65 centimetres (26 in) total length.[2]
Distribution and habitat
[edit]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
[edit]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]
Reproduction
