Few enlarged teeth on the roof of the mouth. Fewer anal rays and more gill rakers. Body compressed and photophores extremely small (Ref. 37473).

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 Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Αβγά | Γονιμότητα | Προνύμφες

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).
