This species is distinguished by the following characters: body moderately elongate, its depth 3-3.4 times in standard length; head length 1.1-1.3 times in body depth, 2.6-3 times in SL, dorsal profile near eye convex without a distinct hump; snout length 1.8-2.1 times in HL, measured without the lip the snout is 0.7-0.9 times in cheek height, its dorsal profile nearly straight or slightly concave, snout angle relative to upper jaw between 54° and 65°; interorbital space flat or slightly convex; posterior nostril a longitudinal oblong opening, closer to orbit than anterior nostril; eye situated close or slightly removed from dorsal profile, its length 3.9-4.7 times in HL; cheek height 2.4-3.3 times in HL; lateral teeth in jaws conical; outer surface of maxilla smooth or with a longitudinal ridge; D X,9 with the 3rd dorsal-fin spine the longest, its length 2.4-2.7 times in body depth; A III,8 with the first soft ray usually the longest, its length shorter than length of base of soft-rayed portion of anal fin and 1.4-1.8 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; 47-49 lateral-line scales; 4 ½ scale rows between lateral line and base of middle dorsal-fin spines; 15-16 scale rows in transverse series between origin of anal fin and lateral line; usually 15 rows in lower series of scales around caudal peduncle; 7-10 scales in supratemporal patch; inner surface of pectoral-fin base without scales; posterior angle of operculum with a wide scaleless area. Colour of body olive grey or brown, with scattered irregular small black blotches; lips and a spot on upper edge of operculum usually red; fins pale or pinkish (Ref. 114226).
Body shape (shape guide): fusiform / normal; Cross section: oval.
體色是橄欖色-灰色或者褐色,有分散的不規則的小黑色的斑塊。 鰓蓋的上緣通常有一個紅色的斑點。 唇通常是紅色的。 鰭是灰白或略帶桃色的。
Found over sand and rubble areas of outer reef slopes (Ref. 30573). Feeds mainly on crustaceans, fish, echinoderms and mollusks (Ref. 30573). In New Caledonia, spawning peaks are observed in December and a fairly high percentage of gonads in advanced stages of maturity occurs between October and February (Ref. 9775). Caught mostly by handline, trap, and trawl. Marketed mostly fresh. An excellent food fish (Ref. 114226).
發現在外礁斜坡的沙子與碎石區上了。 (參考文獻 30573) 主要吃甲殼動物，魚，棘皮動物與軟體動物。 (參考文獻 30573) 在被產卵巔峰在十二月被觀察到的新加勒多尼亞與後階段成熟期一個百分比很高的生殖腺在十月與二月之間出現。 在市場上銷售生鮮地了。 (參考文獻 9775)
