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); jespersenae: In honor of biologist Åse Jespersen (b. 1955), University of Copenhagen, for her contributions to the reproductive biology of hagfishes. (See ETYFish).

海洋 深海底的; 深度上下限 752 - 1556 m (Ref. 54824). 深水域
North Atlantic: off West Greenland, in the eastern Davis Strait. Denmark Strait, Reykjanes Ridge, and South East of Iceland. Occurs sympatrically with Myxine glutinosa, although with a rather limited overlap in vertical distribution (772-1556 vs. 64-782) and no documented capture of both species in the same haul or trap exists.
北大西洋: 外海的格陵兰西方部, 在戴维斯海峡东部。 冰岛丹麦海峡， Reykjanes 脊与东南方。 与 Myxine glutinosa 生存分布区重迭, 虽然具有一个在垂直的分布 (772-1556 vs.64-782) 中的相当有限制的重迭与在一样的两者种的没有被证明的抓取拖网或者困住存在。

Diagnosis: Color grayish brown with whitish head, the white extending posteriorly in a mid-ventral stripe of varying length; surrounding slime pores, PCD, gill aperture, cloaca, CFF, and VFF margins whitish. Two paired, pointed, or comb-shaped, bilaterally symmetrical nasal-sinus papillae with 2-5 distal fringes and 2 cusps in each row fused at their bases. Additional cusps in anterior rows 7-9 and posterior rows 8-10; total cusps 38-44. Pairs of gill pouches 6. Slime pores: prebranchial 28-37; trunk 65-74; tail 11-15; total 107-121. Body slender, depth over cloaca 2.9-4.3% TL; ventral finfold originates within anterior 10% of trunk; caudal finfold termination dorsally above cloaca to posterior 7% of trunk (Ref. 54824).
鉴别: 色彩浅灰褐色有微白色的正在向后延伸的头部，白色在一腹面中央不同长度的斑纹; 周围的黏液孔， PCD ，鳃孔，泄殖腔， CFF 与 VFF 边缘微白色的。 二个成对的﹐尖的﹐或梳状的, 左右对称鼻骨-窦乳突在他们的基底被融合的每列中有两个 -5个末梢部的穗缘与 2个尖头。 在前面的列 7-9 与后列 8-10 中的附加尖头; 总尖头 38-44. 对鳃囊 6. 黏液孔: 前鳃 28-37; 躯干 65-74; 尾部 11-15; 总计 107-121 。 身体细长的, 在泄殖腔 2.9-4.3% TL 上的深度; 腹面鰭褶在前面的 10% 的軀幹裡面開始; 尾鰭的鰭褶終止背面在泄殖腔之上對在後部的 7% 的軀幹.(參考文獻 54824)
Occurs in muddy bottoms. Eggs taken from a damaged specimen in various stages of maturation , elliptical up to 23.6 X 8.5 mm; all eggs are in mesenteries and no anchor filaments were found (Ref. 54824).
