Etymology: Scopelosaurus: Greek, skopelos = a lantern fish + Greek, sauros = lizard (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; oceanodromous (Ref. 51243); depth range 70 - 2500 m (Ref. 58426). Deep-water; 71°N - 18°S, 81°W - 15°E
North Atlantic: subarctic region to the subtropical latitudes.

Maturity: Lm ?  range ? - ? cm
Max length : 36.4 cm SL male/unsexed; (Ref. 6552); common length : 35.0 cm SL male/unsexed; (Ref. 6552)
Adults found between 500-800 m depth while the oceanic young stages between 70-200 m (Ref. 6689). Bathypelagic (Ref. 58426). The young feeds mainly on copepods while the large ones on euphausiids, hyperiids and mesopelagic fishes. Adults undertake far-ranging feeding migrations (outside the spawning season) to the slope areas of Europe, North America and West Africa. Spawning probably occurs in midwater far offshore, with a concentration in the Sargasso Sea (Ref. 6689).
