背棘 (總數) : 10; 背的軟條 (總數) : 9; 臀棘: 3; 臀鰭軟條: 8. This species is distinguished by the following characters: body moderately deep, its depth 2.3-2.5 times in standard length; head length 0.8-1.0 times in body depth, 2.5-2.8 times in SL, dorsal profile near eye nearly straight or slightly convex; snout moderately short, its length about 1.9-2.2 times in head length, measured without the lip the snout is 0.9-1.0 times in cheek height, its dorsal profile concave, snout angle relative to upper jaw between 53° and 64°; interorbital space convex or almost flat; posterior nostril an oblong longitudinal opening, closer to orbit than anterior nostril; eye situated close to or slightly removed from dorsal profile, its length 3.3-4.6 times in HL; cheek moderately high, its height 2.1-2.7 times in HL; lateral teeth in jaws of adults molars or rounded; outer surface of maxilla usually smooth; D X,9, the 4th or 5th dorsal-fin spine the longest, its length 2.7-3.3 times in body depth; A III,8 with the 3rd, 4th or 5th soft ray usually the longest, its length much longer than length of base of soft-rayed portion of anal fin and 0.7-1 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; 44-46 lateral-line scales; 4 ½ scale rows between lateral line and base of middle dorsal-fin spines; 15-17 scale rows in transverse series between origin of anal fin and lateral line; usually 15 rows in lower series of scales around caudal peduncle; 5-9 scales in supratemporal patch; inner surface of pectoral-fin base densely covered with scales; posterior angle of operculum fully scaly. Colour of head and body brown or rust red, lighter ventrally; sometimes 2 light bars on caudal peduncle; area around eye, a broad streak from eye to tip of snout, lips, and base of pectoral fins red; all fins reddish, often a bright red or orange (Ref. 114226).
Body shape (shape guide): fusiform / normal; Cross section: oval.
尾鰭是只略微分叉，頂端圓的。 胸鰭的內面覆滿鱗片; 鰓蓋的後面的角是完全覆蓋著鱗片。 頭部與身體是褐色或赭紅色, 變成腹部顏色較淡。 有時在梗上有二個淺色的橫帶。 一個寬的白色條紋開始從眼而且結束於吻尖。 胸鰭的唇與基底是紅色的。 鰭是淡紅的, 時常鮮紅色或橘色。

Occurs over coral reefs and adjacent sandy areas. May be solitary or in small groups. Feeds on echinoderms, mollusks, crustaceans, and small fish. Caught mostly by handlines and traps. Marketed fresh. Also caught with handlines (Ref. 9775, 687103).
生活在珊瑚礁與毗連的沙地之上。 可能是獨居性或形成小群魚群。 吃棘皮動物，軟體動物，甲殼動物與小魚。 也用手執的釣絲捕獲。 (參考文獻 9775) 在市場上銷售生鮮地了。 (參考文獻 9775) 在帛琉, 出現沿著外部障礙礁石斜坡深度 2 到 10 公尺的上緣.(參考文獻 37816)
