Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 500 m (Ref. 5951). Deep-water; 41°N - 30°S, 42°W - 2°W (Ref. 86868)
Atlantic Ocean: in the north up to 37°-41°N, southern limit to the west is 30°N and in the east 11°N; SW Atlantic at 30°S, 42°W; SE Atlantic between 16°-22°N and 2°-7°W.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 4465)
Fairly common in deep oceanic waters, usually living deeper than 500 m during the day. Smaller individuals migrate to near-surface or even surface waters at night. Feeds on midwater fishes and crustaceans (Ref. 2802).
