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 65cm (26inches) total length.[1]
It is found off Southern California, Peru, and Chile in marine bathydemersal habitats approximately 700m (2,300feet) to 1860m (6,100feet) deep.
It grows to 65cm (26inches) total length and is similar in appearance to other hagfish. Gonads are situated in the peritoneal cavity.
The whiteface hagfish becomes male when the posterior part of the gonads develop and female if the anterior part develops. If both develop, the fish becomes hemaphroditic, and if none develops, the fish becomes sterile.
