Large adult males (about 17 cm) with more definite convexity of snout profile.
成魚的身體深灰褐色; 稚魚黃色; 在鰓裂的上端是一條鮮橘色的水平條紋後面, 有帶紫色的黑色邊緣。 頭部與前半部的身體通常突然地比後半段灰白。 前面的鰓耙 24-28; 在後部的 23-27. 大的雄性成魚 (大約 17 公分) 有更明顯中凸的吻輪廓。
Inhabit seaward reefs, in areas of bare rock or mixed rubble and sand, from 9 to at least 46 m depth; juveniles inhabit protected bays and lagoons, singly or in small groups in as little as 3 m (Ref. 1602, 48637). Benthopelagic (Ref. 58302). Adults occur singly or in schools and feed on surface film of detritus, diatoms, and fine filamentous algae covering sand and bare rock (Ref. 1602). Rarely poisonous (Ref. 4795).
在裸露岩石或混合的碎石與沙的區域中，棲息於臨海礁石, 從 9 到至少 46 公尺深; 稚魚棲息於遮蔽的內灣與潟湖, 各別地或形成小群魚群在淺到 3 公尺中.(參考文獻 1602) 成魚各別地出現或者成群而且吃表面的碎屑薄片，矽藻與細的菌絲藻覆蓋沙子與裸露的岩石.(參考文獻 1602) 此魚種是很少有毒的。 (參考文獻 4795)
