Etymology: Ceratoscopelus: Greek, keras, -atos = horn + Greek, skopelos = a lantern fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 391 - 2056 m (Ref. 27311). Deep-water; 42°N - 65°S, 180°W - 180°E
Atlantic Ocean: 35°N (eastern limit) and 42°N (western limit) south to the Subtropical Convergence. Pacific Ocean: tropical and subtropical waters (Ref. 4066). Indian Ocean: 20°N-45°S (Ref. 4066). Reported to be common in southern Africa (Ref. 4066). South China Sea and East China Sea (Ref.74511).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - ? cm
Max length : 8.1 cm SL male/unsexed; (Ref. 5182)
Oceanic species found between 700 and 1,500 m during the day; between 20 and 200 m at night (Ref. 4775) with maximum abundance between 50 and 100 m (Ref. 47377). Size stratification with depth both day and night (Ref. 4775). Small juveniles (1.5-1.9 cm) are apparently non-migratory. Known to feed on zooplankton but appears to be adapted for occasional herbivory (Ref. 28809).
