Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 20 - 25. Body fairly elongate. Snout moderate, about 3/4 eye diameter; maxilla moderate, tip pointed, reaching onto inter-operculum, but not to edge of gill cover; gill cover canals of walkeri-type. Anal fin moderate, its origin usually somewhat before midpoint of dorsal fin base. A silver stripe along flank, about 3/4 eye diameter.
Body shape (shape guide): elongated; Cross section: oval.
Reportedly common in estuaries and backwaters of bays and occasionally near shores outside bays (Ref. 6792). The fifth most abundant fish taken by various gear in Newport Bay, California; a midwater schooling species caught in bag seine hauls mainly in July and September (Ref. 6361). Oviparous, with planktonic eggs and larvae (Ref. 35602).
