線鰻科 (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.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 173 - 222; 臀鰭軟條: 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.
最容易用它的灰白顏色與 N. scolopaceus 區分了; 有更眼眶後的與前鰓蓋骨孔。 由側線孔形成的長方形更短與更高超過在 scolopaceus 中. 在它的灰白顏色中與 N. curvirostris 相似，但是皮下的深色橫帶不是一樣明顯的。 能立即與 curvirostris 區分了藉由眾多的眼眶後的與前鰓蓋骨孔與比較短與比較高很多長方形由側線孔形成了。 超過 curvirostris 有較小的齒。
Mesopelagic (Ref. 58302). Minimum depth from Ref. 58018.
