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); wisneri: In honor of American ichthyologist Robert L. Wisner (1921-2005), Scripps Institution of Oceanography, for his contributions to hagfish biology (See ETYFish).
Eponymy: Robert ‘Bob’ Lester Wisner (1912–2005) was an American ichthyologist. [...] (Ref. 128868), visit book page.

Brachial length 4.58% of total length; six pairs of gill pouches and gill apertures, gill apertures closely spaced in straight line; external opening of pharyngocutaneous duct (PCD) confluent with the most posterior left gill aperture (51 of 59 specimens examined), and much larger than other apertures; fused unicuspid teeth; eye spots present but not clear (Ref. 31545).
Body shape (shape guide): eel-like.
臂的長度 4.58% 的全長; 六對鰓囊與鰓孔 , 鰓孔在直線中間隔很密的; 咽頭管 (PCD) 的外部開口與最後面的左邊鰓孔 (調查的 59 中的 51 標本), 與比其他的孔大很多匯合; 融合的單犬齒; 眼斑有但是不明顯.(參考文獻 31545)

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 ).西北太平洋: 台灣的東南。
