Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 10.1 cm SL male/unsexed; (Ref. 10755)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 7-9; Anal spines: 0; Anal soft rays: 18 - 21. Medial face of pectorals with dense black pigment (Ref. 6601).

Biology     Glossary (e.g. epibenthic)

Oceanic and mesopelagic (Ref. 6601, 58302). Most adults are taken in hauls to depths exceeding 500 m, none in hauls to depths less than 250 m. Larvae are taken year-round throughout its range, chiefly in hauls to depths less than 200 and apparently not in hauls restricted to the upper 100 m (Ref. 10755). Adults are presumed to prey on other midwater fishes. Synchronous hermaphrodites (Ref. 6691).
