头部尖的, 前额的背面轮廓陡峭的。 眶前骨宽的, 颚骨延伸至大约眼睛中央水平。 成鱼的胸鳍不达到肛门高度。 鳞片列背面平行于侧线。 在颊上的鳞片列 5 或 6. 在眼之下出现狭窄的蓝色条纹或断掉斑点的列。 小的标本从浅水区主要褐色。
Adults occur on rocky bottoms and in the vicinity of coral reefs (Ref. 55, 57393, 81653). Young are frequently encountered in coastal waters, particularly estuaries and sometimes in lower courses of rivers (Ref. 2683, 57393, 81653). Voracious predator (Ref. 57393), feeds mainly on fishes and bottom-dwelling invertebrates (Ref. 55). Size of juveniles ranges from 7.90 to 19.99 cm in length (Ref. 111357).
生活于岩石底部与在邻近珊瑚礁。 幼鱼时常在沿岸水域被见到, 特别地河口与有时在河中.(参考文献 2683) 主要吃鱼与底栖无脊椎动物。
