Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 21; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 12 - 23; Σπόνδυλοι: 48 - 51. Upper jaw rounded and not notched on frontal view. Gill cover without bony radiating striae; tooth plate on tongue broad, almost oval, width about 3 times in length, lateral teeth strong; scales with fine radiating or horizontal striae on exposed posterior part; back steel blue when fresh. Pterotic bulla absent. Last two anal rays normal.
A schooling species in coastal waters. The biology probably resembles that of S. muelleri from which it has not usually been distinguished in earlier studies. Tends to occur in the bottom or midwater except during summer when surface shoals may appear; extends to deeper water in summer and retreats to close inshore for spawning during winter (Ref. 9258). Reported from surface (Ref. 188) to 72 m (Ref. 58489).
