Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 12; Μαλακές ραχιαίες ακτίνες (συνολικά) : 14 - 15; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 13 - 14. Young specimens with fine crossbars; large adults almost uniformly black.
Adults occur in shallow rocky and sandy substrate; juveniles in shallow reefs, estuary mouths and intertidal pools, sandy beach surf zone. Omnivorous on seaweeds, sponges and bivalves. Also feeds on crustaceans, worms, mollusks, and fish. Sold fresh or whole and as bait.
