Northwest to West Central Atlantic: from Massachusetts and Bermuda to Trinidad and Tobago, including the Gulf of Mexico and the islands of the Caribbean.

Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 15.5, range 9 - ? cm
Max length : 38.1 cm SL 雄魚/尚未辨別雌雄; (Ref. 9761); common length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3142); 最大年齡: 31 年 (Ref. 52229)
背棘 (總數) : 9; 背的軟條 (總數) : 23 - 26; 臀棘: 3; 臀鰭軟條: 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)..
尾鰭一般邊緣微凹.(參考文獻 13442) 頭部與身體深的而且扁長形的.(參考文獻 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棲息於淺灘底部。 (參考文獻 13628) 通常成群生活五個或更多個體。 主要日行性種。 吃藻類。 在尾梗的兩邊上的棘可能施放令人痛苦的創傷。 (參考文獻 5217) 在市場上銷售生鮮地了。 最小深度記錄自了參考文獻 27115.
