Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 6; Radios blandos dorsales (total) : 9 - 10; Espinas anales: 1; Radios blandos anales: 8 - 9. Color bluish or brownish dorsally, silvery ventrally (Ref. 6885).
Body shape (shape guide): elongated.
Usually near shore or near the surface (Ref. 2850). Often in small schools (Ref. 2850). Young enter bays (Ref. 2850). Feed mainly on other fishes (Ref. 2850). Pelagic spawners (Ref. 56049). Migrate south from the California coast during autumn, but may remain in front of the Mexican coast throughout the year (Ref. 9345). Utilized fresh, dried or salted and frozen; eaten broiled and baked (Ref. 9988). Considered as potentially dangerous due to its large, sharp teeth and aggressive disposition, though there are no reports of attacks (Ref. 9988).
Pelagic spawner (Ref. 56049).
