This species is distinguished by the following characters: body moderately deep and compressed, its depth 2.6 to 3.2 times in standard length (SL); dorsal profile of body uniformly convex, without any bony horn-like projection or protuberance anteriorly on head; mouth small; incisiform teeth very small, somewhat pointed, finely serrate on edges, as many as 80 in upper jaw and 100 in lower jaw of large adults; continuous unnotched D VI (rarely V or VII),26-29; A II,27-30; pectoral-fin rays 17-18 (usually 17); pelvic fins I,3; caudal fin slightly emarginate in young, becoming truncate in adults; caudal peduncle slender, subcylindrical, with a pair of bony plates on each side that develop large sharp antrorse keels with age; body colour dark brownish grey, shading ventrally to yellowish (life colour may vary from dark brown to light blue-grey); edge of operculum and preopercle usually dark brown; dorsal and anal fins yellowish with faint diagonal brown bands and a blue margin; tongue black at lengths of 25 cm or more (Ref. 9808).
幾乎紡錠狀, 身體淺灰色的到綠褐色的, 腹面灰白的。 在尾柄的每個側邊上的二個弱的固定圓盾。 沒有觸角; 在眼睛前面中的短凹槽。 土黃色前鰓蓋骨邊緣。 超過 25 公分有黑色的舌。 皮膚顆粒狀或像天鵝絨的。 齒小而細長的, 靠攏在一起與尖的。 尾鰭邊緣微凹的當幼魚時。

生物學特性     字彙 (例如 epibenthic)

Inhabits clear lagoon and seaward reef slopes (Ref. 9710, 48637). Benthopelagic (Ref. 58302). Usually seen in large schools (Ref. 90102). Mainly diurnal, it feeds on zooplankton such as crab larvae, arrow worms, pelagic tunicates, and occasionally filamentous red algae. The species is never poisonous (Ref. 4795). Minimum depth reported taken from Ref. 128797.

棲息於清澈的潟湖與臨海礁石斜坡。 (參考文獻 9710) 淺水型。 主要日行性, 它吃浮游動物例如螃蟹幼蟲, 箭蠕蟲,大洋性被囊類與偶然絲狀的紅藻。 此魚種從不是有毒的。 (參考文獻 4795) 最小深度報告取自參考文獻 1602.
