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); springeri: In honor of American shark biologist Stewart Springer (1906-1991), then with the U.S. Fish and Wildlife Service, “who discovered this interesting cyclostome” (See ETYFish).
Eponymy: Stewart ‘Stew’ Springer (1906–1991) was a field naturalist who dropped out of Butler College (1929) but was awarded a baccalaureate by George Washington University (1964), by which time he was world-renowned as an expert on both the taxonomy and [...] (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 ).中西大西洋: 墨西哥灣東北方。
