背面の脊椎 (合計): 5 - 7; 背鰭 (合計): 33-36; 肛門の骨 2-3; 臀鰭: 31 - 34; 脊つい: 40 - 43. First dorsal spine longer than second dorsal spine. Opercles fully scaled (Ref. 27159). Female adult chocolate brown in color with darker fins; prejuveniles silvery with numerous dark spots of various sizes which become larger with age (Ref. 6548).

生物学     用語集 (例 epibenthic)

Inhabit continental slopes of all southern continents (Ref. 6545). Adults found near the bottom; juveniles near the surface, usually in association with krill (Ref. 5194). Feed mainly on salps (Ref. 27150). Eggs float near the sea surface and larvae also inhabit surface waters (Ref. 6390). There is no vertical migration during the day or night (Ref. 27150).
