Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 9; Rayons mous dorsaux (Total) : 10 - 11; Épines anales: 3; Rayons mous anaux: 7. Silvery in color but olive brown above; brown stripes following scale rows above lateral line and the 4 rows below it; spinous dorsal fin with black margins (Ref. 4372). Squamation pattern on the preopercular flange 5-17 scales (Ref. 41102).
Adults inhabit coastal waters including estuaries. They form schools (Ref. 5213). They feed on invertebrates (Ref. 3409). Fry about 10 cm in length enter the estuaries and stay until they reach maturity (Ref. 34363).
