Etymology: Acanthurus: Greek, akantha = thorn + Greek, oura = tail (Ref. 45335).
More on author: Linnaeus.
Taxonomic Remarks
Planes and Fauvelot (2002) studied Acanthurus triostegus over its vast range and published in the journal Evolution and they did not recognize Acanthurus triostegus sandvicensis as a species. FishBase follows Randall, 1956 with A. sandvicensis as a subspecies (synonym) of A. triostegus.

Max length : 27.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3145); common length : 17.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9267)
背棘 (總數) : 9; 背的軟條 (總數) : 22 - 26; 臀棘: 3; 臀鰭軟條: 19 - 22. Body olivaceous gray, with 4 vertical stripes (1 stripe on head across the yellow eye; 1 on caudal peduncle); shading to white ventrally, often with a sharp line of demarcation. Sharp, forward-pointing, erectile spine on each side of caudal peduncle which folds down into a groove. Scales minute. Teeth with denticulations on sides and top. Gill rakers 18-22 in anterior row, 19-24 in posterior row.
Body shape (shape guide): short and / or deep; Cross section: compressed.
身體橄欖色的灰色, 有四個垂直的斑紋 (在黃色的眼對面的頭部上的 1條斑紋; 1 在尾梗上); 顏色變化成腹側白色的, 時常具有一個劃界的銳利線。 銳利地, 朝向前面的, 在進入一個凹槽之內摺疊下來的尾柄的每個側邊上的直立硬棘。 鱗片細小的。 在側邊與頂端上牙齒有小齒狀突起。 在前面的列中鰓耙 18-22,19-24 在後列中。
Adults occur in lagoon and seaward reefs with hard substrate; young abundant in tide pools (Ref. 3145, 48637). Benthopelagic (Ref. 58302). Often feeding near freshwater run-offs where certain algae grow on rocks that are grazed (Ref. 48637). Occasionally form schools; feed on filamentous algae in large aggregations. During spawning, clouds of eggs and sperm are preyed upon by eagle rays which are often present during spawning. Form spawning aggregations (Ref. 27825). Size of metamorphosis from post-larva stage to juvenile is 3.2 cm (Ref. 9267). Utilized as a food fish (Ref. 7364). Minimum depth reported taken from Ref. 27115.
出現在潟湖與臨海礁石，有堅硬的底部; 幼魚豐富的在潮池中.(參考文獻 3145,48637) 時常攝取食物的特定藻類長在岩石上的近的淡水溢流那是啃食.(參考文獻 48637) 偶然地形成魚群; 較大時吃絲狀的藻類群集。 在產卵的時候，大量的卵與精子被鷹魟捕食時常那是在產卵期間出現。 形成產卵群集。 (參考文獻 27825) 從後幼生期到稚魚的銳變的大小是 3.2 公分。 (參考文獻 9267) 作為食用魚.(參考文獻 7364) 最小深度報告取自參考文獻 27115.
