Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 23.0 cm SL αρσενικό/απροσδιόριστο; (Ref. 1008)
Ραχιαίες άκανθες (συνολικά) : 11; Μαλακές ραχιαίες ακτίνες (συνολικά) : 27 - 28; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 7. Strikingly contrasts with other Argyrosomus species by its short, beak-like snout and its concave dorsal profile. Also differs from its congeners by its large eyes (23.8-26.9% HL), narrow interorbital width (15.2-15.6% HL), and long pectoral (23.2-23.8% SL) and pelvic (22.4-23.3% SL) fins.
