Etymology: Scopelosaurus: Greek, skopelos = a lantern fish + Greek, sauros = lizard (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; oceanodromous (Ref. 6689); depth range 50 - 815 m (Ref. 13608). Tropical; 40°N - 30°S
Eastern Atlantic: off Madeira and at 20°N 30°W. Western Atlantic: 34°N to 20°S, with some larval drift up to 40°N. Elsewhere, Indian and Pacific Oceans between 20°N and 30°S.

Morphology | Morphometrics
Larvae are epipelagic, young inhabit the layers between 50-200 m, adults benthopelagic and found deeper than 500 m over continental and insular slopes (Ref. 6552, 6602). Mesopelagic (Ref. 58302). Feeds mainly on zooplankton. Extensive migrations by juveniles and adults, probably for feeding in the subtropical belts. Spawning occurs in tropical waters, especially in the western part of the Atlantic Ocean (Ref. 6689).
