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); chinensis: -ensis, Latin suffix denoting place: China, specifically South China Sea off southeastern Taiwan, type locality. (See ETYFish).

簡短描述
型態特徵 | 形態測量圖
The species has 6 pairs of gill pouches and apertures. Gill apertures in a straight line, not crowded. Eyespots prominent. Fused cusps 3/3, 8-10 unicusps each row, total cusps 46-52. Slime pores: prebranchial 15-19 + branchial 4-5 + trunk 42-45 + tail 11-14. It is distinguished from the other 3 Asian species on Eptatretus by having 6 rather than 7 or 8 pairs of gill pouches (Ref. 51420).
此魚種有 6 對鰓囊與孔。 鰓孔成一直線, 不擁擠。 眼斑突出的。 融合的尖頭 3/3,8-10個單犬齒每列，總尖頭 46-52. 黏液孔: 前鰓 15-19+ 鰓的 4-5+ 軀幹 42-45+ 尾部 11-14. 它是在 Eptatretus 上與另一個區分 3個亞洲種藉著具有 6 而不是 7 或 8個對鰓囊.(參考文獻 51420)

Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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 ).西太平洋: 南中國海。
