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);  ancon: Named for the research vessel B/I Ancon, from which holotype was captured. (See ETYFish).

Short description आकृति विज्ञान | मौरफोमैटरिक्स

External aperture of its last efferent gill duct and pharyngocutaneous duct separated. Gill apertures nonlinear and crowded. Lengths of efferent gill ducts unequal with anterior ones much longer with length of first about 3 times that of last. Gill apertures 6. Slime pores: prebranchial 26; branchial 0; trunk 45; tail 9; total 80. Caudal and ventral finfold not well developed. Head, body, tail and finfold uniformly light brown in alcohol; eyespots faint, gill aperture margins not pale. Ventral aorta bifurcated between the fourth and fifth gill pouches (Ref. 41105).

Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | अंडे | Fecundity | लार्वा

Iteroparous (Ref. 94918). 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 ).
