Scopelarchidae (Pearleyes)
Etymology: Scopelarchoides: Greek, skopelos = a lantern fish + Greek, archos = anus + Greek, oides = similar (Ref. 45335); danae: Named after the Danish research vessel DANA used during the major expeditions of the Carlsberg Foundation, her scientific parties and crews, and the continuing work of the Carlsberg foundation that has enhanced knowledge of the deepsea fauna (Ref. 40783).
Eponymy: The succession of Danish research vessels named ‘Dana’ seem to have been greatly favoured by describers of fish, and often the etymology includes: “…from which the holotype was collected. [...] (Ref. 128868), visit book page.

Ökologie
seewasser bathypelagisch; ozeanodrom (Ref. 51243); tiefenbereich 0 - 1850 m (Ref. 58018). Deep-water
Circumglobal: In tropical to subtropical waters; except Mediterranean Sea. Eastern Central Atlantic: numerous records within the area, all but one are from stations within the Gulf of Guinea (ca 5°N to 11°S and east of 15°W). Western Indian Ocean: numerous records from the Mozambique Channel and off Xai-Xai, Mozambique (Ref. 6601). Western Central Pacific: known only from 2 adult specimens, one collected from near New Caledonia and one from near the Marquesas (Ref. 40783). South China Sea (Ref.74511).
