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).

生態學
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: 外海的格陵蘭西方部, 在戴維斯海峽東部。 冰島丹麥海峽， Reykjanes 脊與東南方。 與 Myxine glutinosa 生存分佈區重疊, 雖然具有一個在垂直的分布 (772-1556 vs.64-782) 中的相當有限制的重疊與在一樣的兩者種的沒有被証明的抓取拖網或者困住存在。

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).
鑑別: 色彩淺灰褐色有微白色的正在向後延伸的頭部，白色在一腹面中央不同長度的斑紋; 周圍的黏液孔， PCD ，鰓孔，泄殖腔， CFF 與 VFF 邊緣微白色的。 二個成對的﹐尖的﹐或梳狀的, 左右對稱鼻骨-竇乳突在他們的基底被融合的每列中有兩個 -5個末梢部的穗緣與 2個尖頭。 在前面的列 7-9 與後列 8-10 中的附加尖頭; 總尖頭 38-44. 對鰓囊 6. 黏液孔: 前鰓 28-37; 軀幹 65-74; 尾部 11-15; 總計 107-121 。 身體細長的, 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).
出現於泥底部。 卵取自了在成熟的各種不同階段中的一件被損壞的標本 ,橢圓形向上到 8.5 mm 23.6個 x; 在腸系膜中的所有卵是，而且沒有錨絲狀突起被發現。 (參考文獻 54824)
