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.

Scavengers which are found on muddy bottoms; feed largely on dead or disabled fish by boring into its skin. Eggs are few and large (20-30 mm).
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 ).
