生態學
海洋 礁區魚類; 深度上下限 0 - 60 m (Ref. 1602), usually 5 - 40 m (Ref. 27115). 熱帶; 32°N - 24°S, 55°E - 138°W
Indo-Pacific: Seychelles to the Marquesas and Tuamoto islands, north to southern Japan, south to the Great Barrier Reef and New Caledonia. Replaced by Acanthurus trisits from the Maldives and Chagos Islands to Bali (Ref. 37816).
印度-太平洋: 塞錫爾群島到馬貴斯群島與 Tuamoto 島, 北至日本南部, 南至大堡礁與新加勒多尼亞。 被 Acanthurus trisits 從馬爾地夫與查哥斯群島到巴里島取代了。 (參考文獻 37816)
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 29.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 90102)
背棘 (總數) : 8; 背的軟條 (總數) : 27 - 30; 臀棘: 3; 臀鰭軟條: 24 - 28. Purplish black in color; an orange diffused patch at edge of gill opening, just above pectoral fin base; a broad black band from upper end of gill opening to margin of gill cover down to isthmus; caudal spine socket with a narrow black margin. Blackish lips; a trace of orange behind eye; a white line under chin extending slightly above rictus. Gill rakers on anterior row 23-26; on posterior row 25-27. Juveniles can exhibit 3 different color patterns mimicking Centropyge species. Caudal fin rounded in juveniles.
帶紫色的黑色; 在鰓裂的邊緣的一個橘色的被擴散的小區塊, 在胸鰭基底的正上方; 從鰓裂的上端到鰓蓋的邊緣的一條寬的黑色條紋向下至峽部; 尾棘插口具有一個狹窄的黑色邊緣。 黑色的唇; 在眼後面的橘色痕跡; 在延伸的下巴下面的一條白色的線在口裂略上方。 鰓耙在前面列 23-26; 在後列 25-27 上. 稚魚能展現 3個不同的彩色斑紋擬態刺尻魚種。 尾鰭在稚魚中圓的。
Occurs in lagoon and seaward reefs; prefers areas of mixed coral, rock, or sand at the base of reefs or ledges, Ref. 48637. Also on silty reefs (Ref. 9710). Found singly (Ref. 9710). Juveniles mimic Centropyge spp. (in Guam, juveniles mimic C. flavissimus but in Palau where this species is absent, they mimic C. vrolikii), Ref. 48637. Presence of a venom gland could not be determined despite the presence of distinct anterolateral grooves; this may be due to the loss of venom glands in adults (Ref. 57406). Feeds on algae (Ref. 89972). Minimum depth reported taken from Ref. 128797.
出現於潟湖與臨海礁石; 偏愛混合珊瑚的區域, 在礁的基底或岩架的岩石或沙子。 也在淤泥的礁上.(參考文獻 9710) 各別地發現。 (參考文獻 9710) 稚魚擬態 刺尻魚 spp 。 (在關島，稚魚擬態 C. flavissimus 但是在帛琉在哪裡這種不存在, 他們擬態 C. vrolikii).
