Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 10; Radios blandos dorsales (total) : 18 - 19; Espinas anales: 3; Radios blandos anales: 13 - 14. Changes from black to silver almost instantly to blend with environment; occasionally mottled or with 7-9 crossbars (Ref. 4370).

Biología     Glosario (por ej. epibenthic)

Found in inshore reefs, rocky and sandy areas. Feeds on mollusks, crustaceans, and other invertebrates (Ref. 5213). Abundant in winter, breeding occurs in deeper water. Becoming scarce because of overfishing (Ref. 36731).
