Ecologia
marino batipelagico; oceanodromo (Ref. 51243); distribuzione batimetrica 0 - 2000 m (Ref. 26165). Deep-water; 33°N - 42°S, 19°E - 139°W
Indian Ocean: 18°N-20°S, to 42°S in the Agulhas Current. Pacific Ocean: 21°N-10°S.
Length at first maturity / Size / Peso / Age
Maturità: Lm ?, range 4 - ? cm
Max length : 10.0 cm TL maschio/sesso non determinato; (Ref. 9835)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 12 - 14; Spine anali: 0; Raggi anali molli: 18 - 20; Vertebre: 31 - 32. Anal organs 10-11; mature males have large 3 to 5 translucent supracaudal gland and smaller infracaudal gland; mature females have small supracaudal gland and much smaller infracaudal patches (Ref. 39633).
Body shape (shape guide): fusiform / normal.
Benthopelagic and mesopelagic in slope and oceanic waters, but usually not high-oceanic. Occurs in the upper 200 m at night (Ref. 4066). Epipelagic in nearshore areas at 0-856 m (Ref. 58302). Occasionally seen during dark nights on slopes that are near very deep water. Attracted by light like moths, becoming disoriented and darting frantically in all directions (Ref. 48635).
