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); sotoi: In honor of Jules Marcelo Rosa Soto (b. 1970), Universidade do Vale do Itajai, for his work on the Brazilian marine fauna and for encouraging Mincarone to study hagfishes (See ETYFish).
Eponymy: Dr Jules Marcelo Rosa Soto (d: 1970) is a Brazilian ichthyologist and geographer who is Curator at Museu Oceanográfico do Vale do Itajaí, Universidade do Vale do Itajaí. [...] (Ref. 128868), visit book page.

Color of live specimens pinkish red with whitish head anterior to first slime pore; whitish middorsal stripe extending from caudal finfold to about over gill apertures. Six pairs of gill pouches; a 2-cusp multicusp on both anterior and posterior sets of cusps, total cusps 38-44. Pores: prebranchial 28-38; trunk 61-73; tail 11-13; total 101-119. Ventral finfold 4-6 mm high.
Body shape (shape guide): eel-like; Cross section: oval.
活体的颜色略带桃色的红色有微白色的头部第一个位于黏液孔前; 从尾鳍的鳍褶延伸的微白色的背面中央的斑纹到大约鳃孔上面。 六对的鳃囊; 在两者的前列与后列的尖头,总尖头 38-44 上的一个 2 尖头的多尖头. 孔: 前鳃 28-38; 躯干 61-73; 尾部 11-13; 总计 101-119 。 腹面鳍褶高度地的 4-6 mm。
Of 30 specimens, 26 were females, 3 males, 1 hermaphrodite. Four females had large eggs about 20 x 6 mm, but none of the eggs with encapsulated anchor filaments. The species lives on the continental slope.

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: 巴西。
