Etymology: Scopelarchus: Greek, skopelos = a lantern fish + Greek, archos = anus (Ref. 45335).
Eponymy: ‘Michael Sars’ was the name of the Norwegian research vessel from which the holotypes were collected. The vessel was named after the Norwegian theologian and biologist Michael Sars (1805–1869). (Ref. 128868), visit book page.

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 7 - 9; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 18 - 21. Medial face of pectorals with dense black pigment (Ref. 6601).
Body shape (shape guide): fusiform / normal.
Oceanic and mesopelagic (Ref. 6601, 58302). Most adults are taken in hauls to depths exceeding 500 m, none in hauls to depths less than 250 m. Larvae are taken year-round throughout its range, chiefly in hauls to depths less than 200 and apparently not in hauls restricted to the upper 100 m (Ref. 10755). Adults are presumed to prey on other midwater fishes. Synchronous hermaphrodites (Ref. 6691).
