Short description Morfologi | Morfometri

This species is distinguished from all its congeners by its ventral fin fold beginning anterior to the first pair of gill apertures (within anterior 27-28% TL) (Ref. 85052).

Biologi     Ordlista (t.ex. epibenthic)

Occurs on soft bottoms of the continental shelf (Ref. 7300). Maximum depth from Ref. 58018.

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Copulatory organ absent. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Ref. 51361 ).
