Etymology: Nemamyxine: nema (Gr.), thread, i.e., a thin, elongate Myxine (See ETYFish); kreffti: In honor of German ichthyologist-herpetologist Gerhard Krefft (1912-1993), Institute für Seefischerei (Hamburg), on the occasion of his 70th birthday, for his many “valuable” contributions to oceanic ichthyology; Krefft also loaned holotype to the authors [not to be confused with his great uncle, German-born Australian adventurer and zoologist Johann Ludwig (Louis) Gerard Krefft (1830-1881), for whom several fishes are named] (See ETYFish).
Eponymy: Dr Gerhard Krefft (1912–1993) was a German ichthyologist and herpetologist whose great uncle was Johann Ludwig Gerard Krefft (below). [...] (Ref. 128868), visit book page.

Diagnosis: Body color light to dark brown, ventral finfold with unpigmented margin. Body extremely slender, depth about 2.4-2.9% of TL. Origin of the ventral finfold well anterior to pharyngocutaneous duct (PCD). Gill pouches 8 pairs. Rostrum rounded. A 3-cusp multicusp on anterior set, a 2-cusp multicusp on posterior set of cusps; total cusps count 32-38. Total pores 124-148 (Ref. 39281).
Body shape (shape guide): eel-like.
鉴别: 体色淡的对深褐色又腹的鳍褶以没有颜色边缘。 身体非常细长, 深度大约 2.4-2.9% 的 TL。 腹鳍褶的起源在咽头管 (PCD) 前。 鳃囊 8 对。 喙圆的。 一个 3 尖头的多尖头在前面组 , 2 尖头的多尖头尖头的在后部组; 总尖头计算 32-38 。 总孔 124-148.(参考文献 39281)

Specimens were caught in winter months, between May and August, a period of lower water temperature due to the Falklands Current influence (Ref. 39281).
生命周期和交配行为 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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: 阿根廷外海與巴西南部。
