背棘 (总数): 8; 背的软条 (总数): 27-31; 臀棘 3; 臀鳍软条: 24 - 28. 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).
身体深黄褐色。 在头部上的橘色的斑点。 胸鳍淡黄色的，尾部的与腹的鳍褐色, 尾鳍的前部灰白的。 尾梗两边具有锐利的,朝向前面的进入一个水平的凹槽之内摺叠下来的直立的硬棘。 鳞片细小的。 稚鱼有 8- 12 灰白的柄倾向向下的与向后在身体上。 齿可动的，细长的, 顶端内曲了而且扩大了; 上颌 5-6 小齿状突起, 低的只有 3-4. 在前面的列中鳃耙 27-36,29-42 在后列中。
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.
栖息于礁石平台与舄湖与临海礁石到深度超过 30 公尺。 生活在珊瑚，岩石，通道，或碎石堆底部之上。 可能单独出现或在小的到非常大的, 时常多种混合的群集, 参考文献 48637. 吃蓝绿藻与硅藻 (在雪卡鱼毒食物链中使得此鱼种一个关键的连结) 的表面薄膜以及各种不同的小型无脊椎动物。
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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: 在区域各处除了夏威夷语，马贵斯群岛与复活岛。 从以一张相片为依据的贝克岛 (美国较小的岛) 记录。 (参考文献 42056) 穆尔登岛与贾维斯岛没有出现。 (参考文献 1602)
