Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 11-15; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 22 - 26. Black in color (Ref. 3991).

Biologi     Ordlista (t.ex. epibenthic)

Bathypelagic (Ref. 58426). There is marked stratification of size with depth and no diel vertical migrations (Ref. 4769). Initial photophore develops at about 1.1 cm SL (Ref. 4769). Feeds on crustaceans (Ref. 58426).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Sex reversal at about 5-10 cm SL (Ref. 4769). Some males become super males, apparently not undergoing sex reversal and are principal spawners (Ref. 4769). Females spawn at about 11 cm SL (Ref. 4769). Males macrosmatic, females microsmatic (Ref. 4769).
