Found between the shore and 100 m depth, on sand or mud bottoms rich in organic matter. Feed mainly on shrimps (Penaeidae), amphipods, crustacean larvae and annelids. The whole life cycle develops on the continental shelf. During reproduction in May and September, adults gather in shallow waters of the estuaries and along the coast. Sexual activity takes place during the rainy season which corresponds to quite a large influx of organic matter, thereby ensuring food for the breeding fish. Sexual dimorphism affects the interorbital width and pectoral fin length of the hidden side. Juveniles remain planktonic for a long time with a high growth rate of >5% per day (Ref. 35237).
发现在海岸与 100 公尺深之间了, 在沙或泥底部上丰富的在有机物。 主要吃虾 (对虾) ，片脚类动物，甲壳类幼生与环节动物。 它的整个生命周期在大陆架上发育。 在繁殖的时候五月时与九月, 成鱼河口聚集在浅水区中而且沿着海岸。 性的活动在相当一个有机物的大流入一致的雨季的时候发生,藉此为繁殖鱼确定食物。 性的同种二形影响眼间骨宽度与隐藏侧边的胸鳍长度。 稚鱼保持浮游性有很长的一段时间具有一个高的增长率 >一天 5%.(参考文献 35237)
