Description

The striated surgeonfish is a surgeonfish (family Acanthuridae) of the Indo-Pacific. The species reaches about 26 cm and has a deep, laterally compressed, brown body with numerous fine longitudinal lines and blue accents. It inhabits reef flats, lagoon and seaward reefs to over 30 m depth and grazes detritus, diatoms and algae from the bottom with a small mouth. On each side of the tail base it bears a sharp, scalpel-like spine with which it defends itself; this can cause cuts. In some areas the flesh can contain ciguatera.
