背棘 (總數) : 8 - 9; 背的軟條 (總數) : 25 - 27; 臀棘: 3; 臀鰭軟條: 23 - 25. Body purplish gray when alive; grayish brown when preserved; a region of dull yellow in front of eye, a lesser extension posterior to lower part of eye; outer 1/3 of pectoral fin yellow, extreme distal part hyaline; dorsal and anal fins yellowish grey basally, dull yellow distally; caudal fin base whitish; caudal fin purplish. Anterior gill rakers 16-24, posterior 17-22. Caudal spine small.
身體帶紫色的灰色當活著的; 淺灰褐色在保存狀態下; 區域暗黃色在眼睛前面中，較少的延長在眼的較下面的部位後面; 外部的胸鰭黃色的 1/3, 最末梢部透明的; 背鰭與臀鰭黃灰色的基部地, 暗黃色末梢部地; 尾鰭基底微白色的; 尾鰭帶紫色的。 前面的鰓耙 16-24, 在後部的 17-22. 尾棘小的。
Live in various reef habitats, sand slopes and lagoons (Ref. 48637). Juveniles inhabit shallow, protected, turbid inshore waters while adults prefer deeper areas of protected bays and lagoons. Also in outer reef areas (Ref. 1602). Benthopelagic (Ref. 58302). Schooling species, feed on diatoms, detritus film of sand, filamentous algae, hydroids, and pieces of fish (Ref. 1602, 48637). Probably the only surgeonfish that readily takes bait (Ref. 12484).
稚魚棲息於水淺且有遮蔽又混濁的近岸水域雖然成魚偏愛遮蔽的內灣與潟湖的較深的區域。 也在外圍礁石區域中。 這群游性種吃矽藻，沙中的碎屑薄片，菌絲藻，水息蟲與魚的碎片。 (參考文獻 1602) 可能輕易地吃餌的唯一的刺尾魚.(參考文獻 12484)
