简单描述 型态特徵 | 形态测量图

背棘 (总数): 9; 背的软条 (总数): 10; 臀棘 3; 臀鳍软条: 9. Males distinct and head looks bright yellow underwater; females drab with white teeth and some pale spots (Ref. 48636). Scales large. 4 median predorsal scales; a transverse pair of smaller scales which overlap medially in mid-dorsal line located directly anterior to 1st median scale; 3 scale rows on cheek, lower row with 1-2 (usually 2) scales. Caudal fin slightly rounded to truncate in initial phase; moderately to deeply emarginate in terminal phase. Adults in initial phase without canines on upper plate, 1 on lower; terminal-phase fish with 1-2 canines on upper and lower plates. Lips largely or entirely cover dental plates.

Inhabits coral-rich areas of outer lagoon and seaward reefs (Ref. 9710). Usually solitary (Ref. 9710). Females usually in small groups with a male nearby; they may mix with females of similar species (Ref. 48636). An uncommon fish patchily distributed through much of its range.

栖息于泻湖外部与临海礁石的珊瑚礁繁盛区域。 (参考文献 9710) 通常独居性的.(参考文献 9710) 雌性在附近用一只雄鱼通常形成小的群; 他们可能和相似种的雌性混合。 (参考文献 48636) 一个稀有的鱼零碎地分布过许多的它分布范围了。
