Duri punggung (Keseluruhan (total)): 10; duri punggung lunak (Keseluruhan (total)): 18-19; Duri dubur 3; Sirip dubur lunak: 13 - 14. Changes from black to silver almost instantly to blend with environment; occasionally mottled or with 7-9 crossbars (Ref. 4370).

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).
