Maturity: Lm ?, range 10 - ? cm
Max length : 26.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2334); common length : 18.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3146); 最大體重: 437.00 g (Ref. 125599); 最大年齡: 36 年 (Ref. 52229)
背棘 (總數): 8; 背的軟條 (總數): 27-31; 臀棘 3; 臀鰭軟條: 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。
Life cycle and mating behavior
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)
