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); knappi:In honor of American ichthyologist Leslie W. Knapp (1929-2017), National Museum of Natural History, Smithsonian Institution, for supplying the authors with study material (See ETYFish). Eponymy: Dr Leslie William Knapp (1929–2017) was an ichthyologist at the Department of Vertebrate Zoology, National Museum of Natural History, Smithsonian. [...] (Ref. 128868), visit book page.
This species is distinguished by the following characters: with a 2-cusp multicusp on both the anterior and posterior sets of cusps; gill pouches 6 on each side; tail slime pores 11-14; total slime pores 116-123; rostrum broadly rounded; ventral finfold nearly vestigial; color pinkish-blue, head and barbels slightly paler than body (Ref. 31699). Body shape (shape guide): eel-like.
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 ).西南大西洋: 已知只來自在福克蘭群島的附近被收集的模式標本了。
