Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 15 - 18; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 17 - 20; Σπόνδυλοι: 55 - 58. Gill rakers usually 32 or less on the first arch and 25 or less on the second arch. Relatively longer upper jaw (usually longer than wide) and lower jaw (usually longer than head length), especially at larger sizes.
Occurs in inshore waters. Forms schools for spawning during mid summer (Ref. 9258). Feeds mainly on larger zooplankton like mysids, crab larvae and polychaete larvae (Ref. 26966).
