Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 11; Radios blandos dorsales (total) : 16 - 18; Espinas anales: 3; Radios blandos anales: 10 - 11. Distinguished by the following characteristics: greenish to greyish brown body color with small reddish brown spots and irregular pale spots and lines; fins with white margins; small portion of population exhibit xanthic pattern which is entirely bright yellow-orange, sometimes with few irregular black spots; depth of body contained 2.7-3.1 times in SL; head length 2.6-2.8 times in SL; angle of preopercle in adults with weakly-developed serrate lobe; posterior nostrils of large adults 2-3 times larger than anterior ones (Ref. 89707).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Prefers rocky areas in shallow water at depths of about 50 m. Adults feed on schools of the flatiron herring, Harengula thrissina, and anchoveta, Cetengraulis mysticetus when available; if not, on other schooling fishes or non-schooling fishes. Most feed at dawn and dusk, with a peak in activity about 20 minutes after sunset. Juveniles feed throughout the day on a variety of benthic fishes and crustaceans.
