Short description Morfologia | Morfometria

Spine dorsali (totale): 10; Raggi dorsali molli (totale): 18-19; Spine anali 3; Raggi anali molli: 13 - 14. Changes from black to silver almost instantly to blend with environment; occasionally mottled or with 7-9 crossbars (Ref. 4370).

Biologia     Glossario (es. 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).
