Etymology: Scopelarchus: Greek, skopelos = a lantern fish + Greek, archos = anus (Ref. 45335). More on author: Alcock.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 0 - 4000 m (Ref. 74511). Deep-water
Atlantic Ocean: mainly in tropical areas (Ref. 6601), widespread in the eastern Atlantic with records from ca. 7°N to 23°S, but unknown from the Gulf of Guinea/Benguela Current. Indo-Pacific: in tropical and subtropical areas (Ref. 6601). Eastern Pacific: in the California Current region off southern California and Baja California peninsula (Ref. 35929); off Chile (Ref. 9068). South China Sea (Ref.74511).

Morphology | Morphometrics
Oceanic and mesopelagic (Ref. 6601, 58302, 75154). Adults have been captured at depths in excess of 500 m, although they have also been captured in the upper 150 m at night. Larvae have usually been taken in hauls restricted to the upper 100 m. Synchronous hermaphrodites (Ref. 10755). Oviparous, with planktonic larvae (Ref. 35929).
