Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 25 - 29; Anal spines: 1; Anal soft rays: 18 - 24; Vertebrae: 27 - 29. Body black dorsally, silvery on sides (Ref. 6622). Branchiostegal rays: 7-8 (Ref. 36622). Body deep, heavy, sides straight. Large adults very dark brown (Ref. 37108).

Biology     Glossary (e.g. epibenthic)

Juveniles are found from near surface to about 250 m to more than 1,000 m (Ref. 6536). Largest adults may be benthopelagic (Ref. 9851). Adults are plankton-eaters like the other members of the family (Ref. 6744). Oviparous, with planktonic larvae (Ref. 36622).
