背棘 (总数): 10; 背的软条 (总数): 11-12; 臀棘 3; 臀鳍软条: 8. Lower jaw projecting slightly beyond upper jaw; lower corner of preopercle greatly projecting and strongly serrated. Preorbital bone broad, maxilla extending nearly to mid-eye level. Preopercular notch and knob moderate. Scale rows on back rising obliquely above lateral line. Back and upper side gray to dark olive grading to silvery ventrally. Usually with a black spot, about eye size, on lateral line below the anterior soft dorsal-fin rays.
下颌突出的略超过上颌; 前鳃盖骨的低角落非常突出而且深锯齿状的。 眶前骨宽的, 颚骨对眼睛中央水平几乎延伸。 前鳃盖骨凹槽与疖瘤中等的。 鳞片列背面斜向上升在侧联机面。 背面与上侧面灰色到深橄榄色渐层色到银色的腹地。 通常有一个黑色的斑点, 大约眼睛大小, 在侧联机在前面的软背鳍鳍条之下。
Adults inhabit clear shallow waters over rocky bottoms in the vicinity of coral reefs, less frequently in sandy or seagrass areas. They often form large aggregations during the day. They feed at night mainly on small fish, shrimps, crabs and cephalopods (Ref. 78464).
在邻近珊瑚礁栖息于在岩石底部上的清澈浅水域, 更不时常在沙的或海草区域。 时常形成大的群集在白天期间。 在晚上觅食主要吃小鱼，虾，螃蟹与头足类动物。
