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);  cirrhatus: Latin for having tendrils, i.e., presumed to be a species of “lamprey” with barbels. (See ETYFish).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 0; Spine anali: 0; Raggi anali molli: 0. This species differs from all its congeners except E. caribbeaus, E. goliath, E. menezesi and E. strahani by having 7 pairs of gill pouches and three-cusp multicusps on the anterior and posterior rows of cusps. It differs from E. caribbeaus in number of anterior unicusps (8-11 vs. 11-13), posterior unicusps (7-9 vs. 10-11), total cusps (43-51 vs. 54-58) and prebranchial pores (16-20 vs. 13-15); from E. goliath in number of anterior unicusps (8-11 vs. 11-13), total cusps (43-51 vs. 54) and trunk pores (46-53 vs. 57-58); from E. menezesi in number of posterior unicusps (7-9 vs. 9-12), total cusps (43-51 vs. 52-60), tail pores (10-14 vs. 14-18); from E. strahani by its number of prebranchial pores (16-20 vs. 13-16) (Ref. 85052).

Biologia     Glossario (es. epibenthic)

Occurs on soft bottoms of the continental slope (Ref. 7300). Able to form locally abundant populations and is often associated with inshore reefs (Ref. 85052).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

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 ).
