This species is distinguished by the following characters: body deep and compressed, its depth 1.9-2.3 times in standard length or SL; mouth small, teeth numerous (> 30 in jaws of adults), movable, slender and elongate, with expanded incurved tips which are denticulate on the lateral margin (6 denticulations on upper and 4 on lower teeth); total gill rakers on first gill arch 27-36; a continuous unnotched dorsal fin with VIII,27-31; AIII,24-28; caudal fin lunate, concavity 3.7-6 times in SL; a lancet-like spine on caudal peduncle which folds into a deep horizontal groove; colour dark olive to yellowish brown with blue or blue-grey lengthwise lines on body and small orange spots on head and nape; dorsal and anal fins with about 5 lengthwise dark bluish bands; pectoral fins pale with brownish yellow rays; a small blackish spot at rear base of dorsal fin of juveniles and small adults (Ref. 9808).
Body shape (shape guide): short and / or deep; Cross section: compressed.
身體深黃褐色。 在頭部上的橘色的斑點。 胸鰭淡黃色的﹐尾部的與腹的鰭褐色, 尾鰭的前部灰白的。 尾梗兩邊具有銳利的,朝向前面的進入一個水平的凹槽之內摺疊下來的直立的硬棘。 鱗片細小的。 稚魚有 8- 12 灰白的柄傾向向下的與向後在身體上。 齒可動的﹐細長的, 頂端內曲了而且擴大了; 上頜 5-6 小齒狀突起, 低的只有 3-4. 在前面的列中鰓耙 27-36,29-42 在後列中。
Inhabits reef flats and lagoon and seaward reefs to a depth of over 30 m. Occurs over coral (Ref. 58534), rock, pavement, or rubble substrates. May occur singly or in small to very large, often mixed-species aggregations (Ref. 48637). Feeds on surface film of blue-green algae and diatoms (making this species a key link in the ciguatera food chain) as well as on various small invertebrates.
棲息於礁石平臺與潟湖與臨海礁石到深度超過 30 公尺。 生活在珊瑚 (參考文獻 58534) ，岩石，通道，或碎石堆底部之上。 可能單獨出現或在小的到非常大的, 時常多種混合的群集.(參考文獻 48637) 吃藍綠藻與矽藻 (在雪卡魚毒食物鏈中使得此魚種一個關鍵的連結) 的表面薄膜以及各種不同的小型無脊椎動物。

成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
In Tahiti, spawning starts near full moon with the formation of schools of several thousand fish at various depths. The fish remain almost motionless for between 1 to 3 hrs, then change their normal color to pale grey. About 4 or 5 fishes rise a few yards above main school and swim around each other discharging milt and eggs, then return to former place and replaced by another group to spawn.印度-太平洋: 在區域各處除了夏威夷語，馬貴斯群島與復活島。 從以一張相片為依據的貝克島 (美國較小的島) 記錄。 (參考文獻 42056) 莫爾登島與賈維斯島沒有出現。 (參考文獻 1602)
