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); mccoskeri: In honor of American ichthyologist John E. McCosker (b. 1945), California Academy of Sciences, for his work on Caribbean and Panamanian fishes, and for providing holotype (See ETYFish).
Eponymy: Dr John Edward McCosker (d: 1945) is an ichthyologist and evolutionary biologist who is Senior Scientist and first Professor of Aquatic Research at California Academy of Sciences, San Francisco. [...] (Ref. 128868), visit book page.

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 ).中西大西洋: 加勒比海南部海洋。
