Description

The pale-lipped surgeonfish is a large surgeonfish (Acanthuridae) from the Indo-Pacific. The species grows to about 45 cm and has a dark-brown to nearly black, disc-shaped body with conspicuously pale lips and chin and a pale band behind the head. As a reef-dweller it hovers along outer-reef slopes and eats algae and zooplankton. A sharp, scalpel-like spine sits on each side of the tail base that can inflict a deep cut; handle with care.
