This species is distinguished by the following characters: body moderately deep, its depth 2.6-2.8 times in standard length; head length 0.9-1 times in body depth, 2.7-3.1 times in SL length, dorsal profile near eye distinctly or slightly convex; snout short and blunt, its length about 2.0-2.6 times in HL, measured without the lip the snout is 0.9-1 times in cheek height, its dorsal profile nearly straight, snout angle relative to upper jaw between 60° and 70°; interorbital space convex or almost flat; posterior nostril a narrow longitudinal slit, closer to orbit than anterior nostril; eye situated close to dorsal profile, its length 3.4-4.2 times in HL; cheek not very high, its height 2.3-3.1 times in HL; lateral teeth in jaws of adults molars or rounded; outer surface of maxilla smooth or with a longitudinal ridge; D X,9 the 4th or 5th dorsal-fin spine the longest, its length 2.5-3.1 times in body depth; A III,8 with the first soft ray usually the longest, its length almost equal to or longer or shorter than length of base of soft-rayed portion of anal fin and 1.2-1.6 times in length of entire anal-fin base; pectoral-fin rays 13; pelvic-fin membranes between rays closest to body without dense melanophores; cheek without scales; 46-47 lateral-line scales usually; usually 5 ½ (sometimes 4 ½) scale rows between lateral line and base of middle dorsal-fin spines; 14-16 scale rows in transverse series between origin of anal fin and lateral line; 13-14 rows in lower series of scales around caudal peduncle; 4-8 scales in supratemporal patch; inner surface of pectoral-fin base densely covered with scales; posterior angle of operculum fully scaly. Colour of body olive or grey above, shading to silvery white below; a large elliptical black spot, often broadly edged in yellow, on side directly below lateral line and centered at a vertical near the posterior tip of pectoral fins; sometimes light blue dots bordering lower rim of eye and around nostrils; pectoral, pelvic, dorsal, and anal fins white to pinkish; caudal fin orange or reddish; vertical fins sometimes lightly mottled or striped (Ref. 114226).
嘴些微可伸出; 唇厚而肉質的。 內部的胸鰭基底濃密地覆蓋著鱗片了。 色彩是橄欖綠色的背面, 腹側灰白的; 鱗片背面有時具有白色的中心。 一個大的橢圓斑塊,時常寬廣地邊緣是黃色了, 在側邊上直接在側線下而且在胸鰭的一個垂直近後面的頂端集中。 有時淺藍色點毗鄰眼的下面霜與鼻孔的周圍。 胸鰭，腹鰭, 背鰭與臀鰭是白色到略帶桃色的。 尾鰭是橘色或淡紅的。 垂直的鰭有時是有淡色的斑點或斑紋。
Found solitary or in small schools over shallow sandy, coral rubble, mangroves, lagoons, channel and seagrass areas inshore and adjacent to coral reefs. Feeds on polychaetes, crustaceans, mollusks, echinoderms and small fish. Reported to spawn throughout the year during the first five days of the lunar month in large aggregations in Palau. Caught mostly by shore seine, gill nets, traps, and handline. Marketed mostly fresh (Ref. 171, 68703); flesh spoils rapidly (Ref. 4369).
單獨發現或者形成小群魚群於水淺的沙地，珊瑚殘礫，紅樹林，潟湖，峽道與海草區域沿海地區與鄰近珊瑚礁。 吃多毛類動物，甲殼動物，軟體動物，棘皮動物與小魚。 報告的在帛琉較大時在第一個的時候產卵全年度五天的陰曆月群集。 在市場上銷售生鮮地了 (參考文獻 171; 肉很快地腐敗。 (參考文獻 4369)
