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

Issue
The species Acanthurus nigros Günther 1861 is considered valid in Eschmeyer (CofF ver. Sep. 2011: Ref. 88002) following Randall & Parenti (2011). But could be an unjustified ementation of nigroris. More studies are needed.

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 24 - 27; Espinas anales: 3; Radios blandos anales: 23 - 25. Color drab dark brown; spots on body located at the rear base of dorsal and anal fins. Black spot at rear base of dorsal fin not large, its greatest width more than 2 times in eye diameter. White posterior margin of caudal fin very narrow, its width less than 4 times in pupil diameter. No definite black margin around groove of peduncular spine. Body depth 1.8 to 2 times in SL. Maximum standard length about 20 cm (Ref 9808).

Inhabits clear lagoon and seaward reefs; often in areas with mixed coral, pavement, rubble and sand substrates (Ref. 1602). Benthopelagic (Ref. 58302). Occurs singly or in small groups (Ref. 9710). Feeds on filamentous algae, diatoms and fine algal film of compacted sand (Ref. 1602). Relatively uncommon throughout Micronesia; rare on Great Barrier Reef.
