Morphology | Morphometrics
(total): 47-51. Head rather long. Pectoral fin tips usually reaching origin of anal fin. Caudal fin usually truncate, progressively becoming concave with growth. Color is steel gray to blackish on back, silvery white on sides and belly.
Feeds mainly on small fishes, and to a lesser extent on crustaceans and cephalopods. Undergoes seasonal latitudinal migrations (Ref. 9709). Spawning takes place in northern areas from January to March (Doutre, 1960), and from October to March (López Abellán and Ariz Telleía, 1993). Marketed fresh or frozen (Ref. 58452). Minimum depth reported from Ref. 26999.
