Etymology: Acanthurus: Greek, akantha = thorn + Greek, oura = tail (Ref. 45335).
More on author: Linnaeus.

Issue
Planes and Fauvelot (2002) studied Acanthurus triostegus over its vast range and published in the journal Evolution and they did not recognize Acanthurus triostegus sandvicensis as a species. FishBase follows Randall, 1956 with A. sandvicensis as a subspecies (synonym) of A. triostegus.

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 22 - 26; Espinas anales: 3; Radios blandos anales: 19 - 22. Body olivaceous gray, with 4 vertical stripes (1 stripe on head across the yellow eye; 1 on caudal peduncle); shading to white ventrally, often with a sharp line of demarcation. Sharp, forward-pointing, erectile spine on each side of caudal peduncle which folds down into a groove. Scales minute. Teeth with denticulations on sides and top. Gill rakers 18-22 in anterior row, 19-24 in posterior row.

Biología     Glosario (por ej. epibenthic)

Adults occur in lagoon and seaward reefs with hard substrate; young abundant in tide pools (Ref. 3145, 48637). Benthopelagic (Ref. 58302). Often feeding near freshwater run-offs where certain algae grow on rocks that are grazed (Ref. 48637). Occasionally form schools; feed on filamentous algae in large aggregations. During spawning, clouds of eggs and sperm are preyed upon by eagle rays which are often present during spawning. Form spawning aggregations (Ref. 27825). Size of metamorphosis from post-larva stage to juvenile is 3.2 cm (Ref. 9267). Utilized as a food fish (Ref. 7364). Minimum depth reported taken from Ref. 27115.
