Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 15.5, range 9 - ? cm
Max length : 38.1 cm SL 雄鱼/尚未辨别雌雄; (Ref. 9761); common length : 25.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3142); 最大年龄: 31 年 (Ref. 52229)
背棘 (总数) : 9; 背的软条 (总数) : 23 - 26; 臀棘: 3; 臀鳍软条: 21 - 23. This species is distinguished by the following set of characters: D IX, 23-26; A III, 21-23; pectoral rays 15-17; gill rakers 18-24; covered with very small ctenoid scales; spatulate teeth have denticulate edges, upper jaw with 14, lower jaw 16; body depth about 2.0 in standard length; caudal fin lunate, concavity of caudal fin 5.0-12.0 in SL, more concave in adults; length of caudal spine 3.0-3.5 in SL; eye diameter 3.0-3.5 in head length; colour of body yellowish to grayish brown, without dark vertical bars; yellow lines radiating from the posterior margin of eye; translucent pectoral fin with yellow tints; white or pale spot at the base of caudal fin; posterior margin of caudal, anal and dorsal fins have light blue or white margin (Ref. 87362)..
尾鳍一般边缘微凹.(参考文献 13442) 头部与身体深的而且扁长形的.(参考文献 26938)
Inhabits shallow bottoms with coral or rocky formations (Ref. 13628); also found around inshore rocky areas with patches of sand, feeding primarily on benthic algae and occasionally grazing on seagrass beds (Ref. 87362). Usually occurs in groups of five or more individuals. Mainly diurnal species. The spine on both sides of the caudal peduncle may inflict painful wounds (Ref. 5217). Marketed fresh. Minimum depth reported from Ref. 27115. Previously reported longevity of 31 years from Ref. 52229 refers to Acanthurus bahianus, a case of misidentification.
用珊瑚或岩石的形成栖息于浅滩底部。 (参考文献 13628) 通常成群生活五个或更多个体。 主要日行性种。 吃藻类。 在尾梗的两边上的棘可能施放令人痛苦的创伤。 (参考文献 5217) 在市场上销售生鲜地了。 最小深度记录自了参考文献 27115.
