Morphology | Morphometrics
(total): 45-52. Head large and little depressed. Pectoral fin tips usually reaching the origin of anal fin in small but not in large individuals. Scales easily shed. Color usually blackish on back, steel gray to blackish on belly; caudal fin white-edged.
Feeds mainly on small fishes and partly on squids and shrimps (Ref. 1371). Marketed mostly fresh and frozen, also used for fishmeal and oil (Ref. 1371). Minimum depth reported taken from Ref. 1371.
