背棘 (总数) : 6; 背的软条 (总数) : 26 - 29; 臀棘: 2; 臀鳍软条: 27 - 30. 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).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
几乎纺锭状, 身体浅灰色的到绿褐色的, 腹面灰白的。 在尾柄的每个侧边上的二个弱的固定圆盾。 没有触角; 在眼睛前面中的短凹槽。 土黄色前鳃盖骨边缘。 超过 25 公分有黑色的舌。 皮肤颗粒状或像天鹅绒的。 齿小而细长的, 靠拢在一起与尖的。 尾鳍边缘微凹的当幼鱼时。

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.
栖息于清澈的舄湖与临海礁石斜坡。 (参考文献 9710,48637) 浅水型。 主要日行性, 它吃浮游动物例如螃蟹幼虫, 箭蠕虫，大洋性被囊类与偶然丝状的红藻。 此鱼种从不是有毒的。 (参考文献 4795)
