Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 3; Raggi anali molli: 10 - 11. Silvery with distinct crossbars (Ref. 3198).
Found over sandy substrate. Juveniles use estuaries as nurseries (Ref. 27121). Feeds on worms, crustaceans, and mollusks especially mussels (Ref. 5213). Spawns during spring and summer close inshore (Ref. 36731).
