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).
Environment: milieu / climate zone / depth range / distribution range
Écologie
marin bathypélagique; océanodrome (Ref. 51243); profondeur 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).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 12.3 cm SL mâle / non sexé; (Ref. 13608)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 6 - 9; Épines anales: 0; Rayons mous anaux: 24 - 27. Dark stripe just below lateral line and extends to lower caudal lobe (Ref. 6601). Pigments lacking on pectoral and pelvic fins; gill filaments not extending to edge of gill covers (Ref. 13608).
Oceanic and mesopelagic (Ref. 6601, 75154). Adults have usually been taken in hauls at depths between 300 to 800 m; most larvae in hauls to depths between 0 to 200 m. Most records in all areas are from localities near continental or insular land masses. Synchronous hermaphrodites (Ref. 10755).
