Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 11; Radios blandos dorsales (total) : 10; Espinas anales: 3; Radios blandos anales: 8. Silvery in color, crossbars fade with age.
Body shape (shape guide): fusiform / normal.
Found over sandy substrate, in estuaries and oceanic waters. Enters lagoons (Ref. 3198). Feeds bottom invertebrates, including worms, crabs and shrimp (Ref. 27121). Spawns in the sea but uses estuaries as nursery grounds. Prime angling fish. Important food fish. Sold fresh and whole in markets.
