Description
The doubleband surgeonfish is a surgeonfish (Acanthuridae) from the Indian Ocean. The species grows to about 31 cm and has an olive-brown, disc-shaped body with two conspicuous, sickle-shaped black bands behind the head and a blue margin along the tail spine. As a reef-dweller it grazes algae from coral and rocky reefs. A sharp, scalpel-like spine sits on each side of the tail base that can inflict a deep cut; handle with care.
