大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 22.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5213)
背棘 (總數) : 8; 背的軟條 (總數) : 24 - 27; 臀棘: 3; 臀鰭軟條: 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). Anterior gill rakers 23-29 (Ref 42056).
在後面的背鰭基底與臀鰭的突出黑色的斑點; 眼 (參考文獻 1602) 的周圍成魚有一個藍色的環。 背鰭與臀鰭深褐色的。 尾鰭褐色當成魚時, 當幼魚時的黃色。 唇的邊緣平滑的。 上顎齒通常有 5個小齒狀突起。 (不包括頂端) 前面的鰓耙 23-29(參考文獻 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).
棲息於珊瑚與深潟湖與臨海礁石的碎石區域。 刮食碎屑薄片，而且單細胞的藻類 (例如腰鞭毛蟲 Gambierdiscus toxicus) 因此產生在雪卡魚毒食物鏈中使得此魚種一個關鍵的連結的雪卡魚毒毒素。 (參考文獻 1602) 用網捕獲了。 (參考文獻 30573)
