Myxinidae (Hagfishes) > Eptatretinae
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); mendozai: In honor of Luis H. “Uchy” Mendoza, captain of the research vessel Crawford from which holotype was collected, for his “experiential knowledge and academic curiosity of the sea, without whose determination and nautical wisdom” the author would never have discovered this hagfish (See ETYFish).
Eponymy: Luis H ‘Uchy’ Mendoza was captain of the research vessel ‘Crawford’ which belonged to the Department of Marine Sciences, University of Puerto Rico. [...] (Ref. 128868), visit book page.

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 ).西大西洋: 加勒比海。
