头部背面轮廓中等倾斜; 眼相当大的, 它的直径大约等于吻尖长。 颊部是覆有鳞片的; 颚骨具有一个纵向的网状脊。 胸鳍内面基底是没有鳞片。 背面区域是褐色的有狭窄的银色斑纹。 其它的头部与身体主要银色对灰色除了 4 或 5 褐色- 橘色的在侧边中的低的 2/3 上。 有一个突出的金黄色的斑块直接地在后面的部分背鳍之下正好在尾梗之前。
Inhabits subtidal reef flats, lagoons, and seaward reefs (Ref. 9710). May be solitary or in groups (Ref. 90102). Sometimes forms aggregations of about a hundred or more individuals. Feeds at night on benthic invertebrates like crabs and gastropods, occasionally on small fish. Usually marketed fresh. Minimum depth reported taken from Ref. 128797.
栖息于亚潮间带的礁石平台，泻湖与临海礁石。 (参考文献 9710) 有时大约一百或更多个体聚集成群。 晚上捕食底栖的无脊椎动物如螃蟹与腹足动物, 偶然地捕食小鱼。 通常生鲜地在市场上销售。
