Etymology: Acanthurus: Greek, akantha = thorn + Greek, oura = tail (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecología
marino; salobre asociado a arrecife; rango de profundidad 0 - 30 m (Ref. 9710), usually 2 - 15 m (Ref. 27115). Tropical; 23°C - 28°C (Ref. 27115); 30°N - 24°S, 39°E - 143°W
Indo-Pacific: East Africa, including the Mascarene Islands (Ref. 37792) to the Tuamoto Islands, north to Ryukyu Islands, south to southern Great Barrier Reef. Not occurring in the Red Sea.
Length at first maturity / Tamaño / Peso / Age
Maturity: Lm 18.4 range ? - ? cm
Max length : 45.3 cm FL macho / no sexado; (Ref. 125599); peso máximo publicado: 2.7 kg (Ref. 125599)
Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 25 - 28; Espinas anales: 3; Radios blandos anales: 23 - 26. Color in life dark brown without lines on body or spots on head (one phase is purplish grey); horizontal black band behind upper gill opening absent on juveniles <6 cm SL; elongate purple band may be present anterior to dorsal origin; caudal fin brown; outer third of pectoral fin pale. Species with gizzard-like stomach.
Occurs in clear lagoon and seaward reefs around isolated coral heads. Solitary or in small groups (Ref. 90102). Prefers sandy bottoms of bays and lagoons rather than the coral reefs like most other Acanthuridae. The species is sometimes poisonous (Ref. 4795). Caught with nets (Ref. 30573). Minimum depth reported taken from Ref. 128797.
Probably spawn in pairs (Ref. 240).
