Nemichthyidae (Snipe eels)
Etymology: Nemichthys: Greek, nema, -atos = filament + Greek, ichthys = fish (Ref. 45335); larseni: Named for Verner Larsen, who began the study of this species while at the University of Copenhagen.
Eponymy: Verner Larsen is a Danish ichthyologist, who began revising Nemichthys whilst still a student at the University of Copenhagen, and who, according to the etymology, “…generously handed over his material” to the authors “…when he was unable to finish [...] (Ref. 128868), visit book page.

简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 173 - 222; 臀鳍软条: 164 - 208. Most easily distinguished from N. scolopaceus by its pale color; has more postorbital and preopercular pores. Rectangle formed by the lateral line pores is shorter and higher than in scolopaceus. Resembles N. curvirostris in its pale color but the subcutaneous dark bars are not as evident. May be instantly distinguished from curvirostris by the more numerous postorbital and preopercular pores and the much shorter and higher rectangle formed by the lateral line pores. Has smaller teeth than curvirostris.
最容易用它的灰白颜色与 N. scolopaceus 区分了; 有更眼眶后的与前鳃盖骨孔。 由侧线孔形成的长方形更短与更高超过在 scolopaceus 中. 在它的灰白颜色中与 N. curvirostris 相似，但是皮下的深色横带不是一样明显的。 能立即与 curvirostris 区分了藉由众多的眼眶后的与前鳃盖骨孔与比较短与比较高很多长方形由侧线孔形成了。 超过 curvirostris 有较小的齿。
Mesopelagic (Ref. 58302). Minimum depth from Ref. 58018.
