Max length : 49.7 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9626); common length : 35.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9626); 最大体重: 900.00 g (Ref. 9626)
Adults are found mainly in brackish and fresh waters; also over muddy bottoms of coastal marine waters (Ref. 5217). May leap out of the water. They return to the sea to reproduce (Ref. 36880). Dorsal and anal spines bear venomous glands (Ref. 40401). Adults are carnivorous (Ref 40401) while juveniles up to 8.2 cm FL feed mainly on scales taken from larger fishes, also on benthic and planktonic crustaceans, and to a minor extent on smaller fishes and polychaetes (Ref. 40402). Juveniles up to 3.0 cm TL adopt a dark brown color pattern while close to decaying plant fragments, an example of camouflage (Ref. 40401, 46533). Over open, detritus-free and light colored sandy bottom, adopts a contrasting yellowish and dark brown pattern, an example of warning colors. Its conspicuous colors are mimicked by juveniles of the non-venomous grunt Pomadasys ramosus (Ref. 46533).
主要发现于半咸淡水与淡水了; 也在海洋沿岸水域的泥底部之上。 (参考文献 5217) 可以跳出水面。 回到海洋繁殖的一个肉食性的鱼.(参考文献 36880) 在背鳍与臀鳍棘上有有毒的腺。 (参考文献 40401) 稚鱼向上到 8.2 公分 FL 主要捕食取自较大的鱼鳞片, 也在底栖性与浮游性的甲壳动物上, 而且对较小的范围捕食小鱼与多毛类的.(参考文献 40402) 稚鱼向上到 3.0 公分TL 拥有一个深褐色的彩色斑纹，状似腐败植物碎片，一个伪装的例子.(参考文献 40401,46533) 在开放的，无碎屑与淡色的沙质底部之上, 拥有一个对比淡黄色而深褐色的图案，一个警告颜色的例子。 它的显着颜色是被非有毒的咕噜咕噜声 多枝石鲈［Pomadasys ramosus］ 的稚鱼拟态.(参考文献 46533)
