背棘 (总数) : 8; 背的软条 (总数) : 24 - 27; 臀棘: 3; 臀鳍软条: 22 - 25. Prominent black spot at the rear base of dorsal and anal fins; adults with a bluish ring around the eye (Ref 1602). Dorsal and anal fins dark brown. Caudal fin brown in adults, yellow in young. Edge of lips smooth. Upper teeth usually with 5 denticulations (not including tip).

在后面的背鳍基底与臀鳍的突出黑色的斑点; 眼 (参考文献 1602) 的周围成鱼有一个蓝色的环。 背鳍与臀鳍深褐色的。 尾鳍褐色当成鱼时, 黄色的当幼鱼时。 唇的边缘平滑的。 上颚齿通常有 5个小齿状突起。 (不包括顶端) 前面的鳃耙 23-29(参考文献 42056).
Inhabits coral and rubble areas of deep lagoon and seaward reefs. Usually solitary, grazing on surface algae (Ref. 90102). Feeds by scooping film of detritus and unicellular algae (e.g. dinoflagellate Gambierdiscus toxicus) that produce ciguatera toxin making this species a key link in the ciguatera food chain (Ref. 1602, 48637). Caught with nets (Ref. 30573).
栖息于珊瑚与深舄湖与临海礁石的碎石区域。 刮食碎屑薄片，而且单细胞的藻类 (例如腰鞭毛虫 Gambierdiscus toxicus) 因此产生在雪卡鱼毒食物链中使得此鱼种一个关键的连结的雪卡鱼毒毒素。 (参考文献 1602,48637) 用网捕获了。 (参考文献 30573)
