Etymology: Myxine: Ancient Greek word for a slimy fish: myxa, slime; -inus, one who, referring to copious amounts of slime produced by M. glutinosa (See ETYFish); ios: Acronym for Institute of Oceanographic Sciences, Wormley, Surrey, England, which supplied holotype (See ETYFish).
Eponymy: IOS stands for the Institute of Oceanographic Sciences, England, which supplied the type specimen of the hagfish. [...] (Ref. 128868), visit book page.

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 ).東大西洋: 西南的外海愛爾蘭與冰島, 外海的西撒哈拉。
