背棘 (總數): 9; 背的軟條 (總數): 26-28; 臀棘 3; 臀鰭軟條: 24 - 26. A deep-bodied surgeonfish (body depth 1.7 in SL) with a conspicuous yellow caudal spine. Has the most distinctive coloration of all western Atlantic surgeonfishes (Ref. 26938).
一個身體縱深刺尾魚 (體高 1.7 分之一標準體長) 具有一個顯著的黃色尾棘。 有所有大西洋西部刺尾魚的最特殊顏色。 (參考文獻 26938)
Inhabits coral reefs, inshore grassy or rocky areas. Forms small groups (Ref. 26235). Mainly diurnal. Feeds entirely on algae (Ref. 5521). At Fernando de Noronha Archipelago in southwestern Atlantic, juveniles hold cleaning stations together with the doctorfish (Acanthurus chirurgus) and sergeant major (Abudefduf saxatilis) and graze algae as well as pick molted skin and parasites from green turtles (Chelonia mydas). This behavior is preceded by a characteristic inspection usually followed by feeding nips on the turtles’ skin (head, limbs, and tail), as well as on the carapace. The most inspected and cleaned body parts are the flippers (Ref. 51385). Diurnal species (Ref. 3194). It forms resident spawning aggregations in late afternoon after high tide (Ref. 27825, 120681, 120682). The spine on both sides of the caudal peduncle may inflict painful wounds (Ref. 5217). Marketed fresh. Maximum depth reported taken from Ref. 127989.
棲息於珊瑚礁，近海草地或岩石區域。 形成小群魚群。 (參考文獻 26235) 主要日行性。 完全地吃藻類。 (參考文獻 5521) 在西南方的大西洋的 Fernando de Noronha 列島，稚魚支撐 , 清潔的區域伴隨著魚醫生 ( 小帶刺尾魚〔Acanthurus chirurgus〕 ) 與魚少校 ( 岩豆娘魚〔Abudefduf saxatilis〕 ) 而且啃食藻類以及剔啄脫皮來自綠海龜 ( Chelonia mydas) 的皮膚與寄生蟲. 這行為進行通常被跟隨著的一個特殊的檢查咬食海龜的皮膚 (頭部，肢翼與尾部), 以及甲殼。 最檢查而且清理身體部份是鰭狀肢.(參考文獻 51385) 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.
