生態學
海洋 礁區魚類; 深度上下限 0 - 90 m (Ref. 9710), usually 5 - 30 m (Ref. 37792). 熱帶; 35°N - 30°S, 105°E - 130°W
East Indian Ocean from Christmas Pacific Ocean: Honshu, Japan south to the Great Barrier Reef and New Caledonia and east to the Hawaiian Islands, French Polynesia, and Pitcairn. Eastern Pacific: Clipperton Island. Once regarded a wide-ranging Indo-Pacific species, the Indian Ocean population is now recognized as a separate species, Naso elegans.
太平洋: 日本本州南至大堡礁與新加勒多尼亞而且東至夏威夷群島，法屬玻里尼西亞與皮特凱恩島。 在東太平洋中, 從克利珀頓島。 曾經被認為是一個廣泛分佈印度-太平洋的種, 印度洋族群現在被鑑定為一個個別的種， Naso elegans 。

Maturity: Lm ? range ? - ? cm
Max length : 46.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 37792); 最大體重: 2.3 kg (Ref. 125599)
背棘 (總數) : 6; 背的軟條 (總數) : 26 - 29; 臀棘: 2; 臀鰭軟條: 27 - 30. This species is distinguished by the following characters: D VI (rarely V or VII),26-29(modally 27); A II,27-30 (rarely 27 or 30); pectoral rays usually 17; body depths of adults 2.6-3.0 in SL; head dorsal profile sloping and smoothly convex (forehead no horn nor protuberances); two large peduncular plates, the keels with forward-projecting points in adults; caudal fin emaginate in young and truncate in adults; body brown to bluish gray, ventral half yellowish gray to yellow, the demarcation along middle of side often abrupt and irregular; edge of opercle and preopercle usually with a dark brown band; margin of lower lip broadly white with upper surface of tongue black in adults; gill rakers are blackish basally; blue caudal fin with a broad, brownish yellow, posterior border which narrows toward corners of fin; it is capable of changing overall into light grayish blue, as when at a cleaning station; when in courtship the males quickly display a broad, bluish white zone on the nape and anterior part of the body , followed by narrow bars of the same color that extend onto lower side (Ref. 54980).
背鰭黑色, 黑色的繼續在後頸之上作為一個尖的突出, 在柔軟部位上的基底與一個寬的外部白色的區域具有一個藍灰色線; 臀鰭主要橘色; 背鰭與臀鰭有狹窄的藍色邊緣與黑色的靠近邊緣的線; 在後部地尾鰭有一條黃色的靠近邊緣的條紋。 (參考文獻 37792) 尾鰭邊緣微凹的，雄性成魚有來自每個角落的尾絲.(參考文獻 37792)
Found in areas of coral, rock, or rubble of lagoon and seaward reefs, Ref. 48637. Benthopelagic (Ref. 58302). Adults usually in small groups. Juveniles in shallow rocky reefs, sometimes in small aggregations mixed with other acanthurids of similar size (Ref. 48637). Feed mainly on leafy brown algae (Sargassum and Dictyota). Sometimes in large aggregations (Ref. 37792). Very seldom poisonous (Ref. 4795). Pair-spawning has been observed.
發現於珊瑚的區域，潟湖與臨海礁石的岩石或碎石了。 主要吃葉狀的褐色藻類 ( 馬尾藻 與 Dictyota) 。 有時較大時群集.(參考文獻 37792) 此魚種是極少有毒的。 (參考文獻 4795) 成對產卵已經被觀察。
