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); fernholmi: In honor of Bo Fernholm (b. 1941), Swedish Museum of Natural History, for his contributions to hagfish biology (See ETYFish).

Six pairs of gill pouches and apertures, gill apertures usually crowded in a slightly curved line; the most posterior left gill aperture not confluent with the external opening of the pharyngocutaneous duct (PCD). Eye spots present but not obvious (Ref. 31545). Branchial length less than 3% of total length. Fused cusps 3/2, total cusps 42-50. Prebranchial slime pores 16=23, total pores 64-71. Ventral finfold poorly developed (Ref. 51420).
Body shape (shape guide): eel-like.
六对的鳃囊与孔 , 鳃孔通常拥挤了在一些微地曲线; 最后面的左边鳃孔不与咽头管 (PCD) 的外部开口汇合。 眼斑呈现但是不是明显.(参考文献 31545) 鳃的长度少于 3% 的全长。 融合的尖头 3/2 ，总尖头 42-50. 前鳃黏液孔 16=23 ，总孔 64-71. 腹面鳍褶发展不良的。 (参考文献 51420)

生命周期和交配行为 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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。
