Description
The bluelined surgeonfish is a surgeonfish (Acanthuridae) from the western Pacific. The species grows to about 26 cm and has a grey-brown, disc-shaped body with fine, light-blue longitudinal lines and a yellowish tinge around the pectoral fin. As a reef-dweller it often hovers in groups above deeper outer-reef slopes and eats zooplankton and algae. A sharp, scalpel-like spine sits on each side of the tail base that can inflict a deep cut; handle with care.
