Épines dorsales (Total) : 10; Rayons mous dorsaux (Total) : 9; Épines anales: 3; Rayons mous anaux: 8. Body is yellowish bronze or gray, becoming lighter ventrally. Sometimes three bronze stripes are on the upper side. The head is gray, brown or sometimes bronze with a series of yellowish cross stripes on the upper portion of the head and snout. A light streak radiates from the eye to the anterior nostril. the lower edge of the orbit has dark purplish spots. The maxilla is reddish. The fins are pale, yellowish or bronze.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Found over seagrass beds, coral reefs and adjacent sandy areas. Feeds mainly on echinoderms, crustaceans, and fish, and to a lesser degree on mollusks. Smaller, more numerous females than males have been confirmed for the Saya de Malta population (Ref. 2295). Marketed fresh (Ref. 171).
