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); burgeri: In honor of German physicist and biologist Heinrich Bürger (ca. 1804-1858), who collected type. (See ETYFish).

Six pairs of gill pouches and gill apertures in a rarely variable linear arrangement. Branchial slime pores, 4-6. The last left gill aperture (GA) is closely adjacent to but separate from the pharyngocutaneous duct (PCD). Eyes spots are prominent (Ref. 31545). White mid-dorsal line prominent; fused cusps 3/2, total cusps 40-42; total slime pores 81-92 (Ref. 51420).
在一个几乎不变的直线排列中的六对鳃囊与鳃孔。 鳃的黏液孔,4-6. 最后的左边鳃孔 (GA) 是紧邻于但是与咽头管 (PCD) 分开. 眼斑是突出的。 (参考文献 31545) 白色的背部中央线突出的; 融合的尖头 3/2, 总尖头 40-42; 总黏液孔 81-92.(参考文献 51420)
Found in the sublittoral zone (Ref. 11230). Usually buries itself in bottom mud (Ref. 26686). Migrates into deeper water to spawn (Ref. 51361, 51374). This is the only member of the family having a seasonal reproductive cycle (Ref. 51361). Food fish in Japan. Hide is processed into leather and exported worldwide, usually as 'eel' leather.

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 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 ). However, there was a presumption of 0.1% or even less that this species manifests functional hermaphroditism (Ref. 51416).
This is the only member of the family having a seasonal reproductive cycle (Ref. 51361).西北太平洋: 日本海與日本東部至台灣。
