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); okinoseanus: -anus, Latin adjectival suffix that means, when attached to a name, “belonging to”: Okinose, Honshu Island, Japan, type locality (See ETYFish).

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 (參考文獻 5193) 與日本南部。
