Etymology: Eptatretus: hepta (Gr.), seven; tretos (Gr.), perforated (i.e., with holes), referring to seven gill apertures on what would later be described as Homea banksii (=E. cirrhatus) [range within genus is 6-14 pairs of gill apertures]. (See ETYFish);  longipinnis: longus (L.), long; pinnis (L.) fins, referring to well-developed fold on ventral fins that extends to branchial region. (See ETYFish).

Short description Morfología | Morfometría

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).

Biología     Glosario (por ej. epibenthic)

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

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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 ).
