Description

The White-freckled surgeonfish is a surgeonfish (Acanthuridae) from reef water of the Indo-West Pacific. The species has a deep, laterally compressed, dark-brown with white freckles on the head body with a small mouth for grazing algae. On each side of the tail base it carries a sharp, scalpel-like keel blade. As a grazer it scrapes algae from coral and rock. The keel blade can inflict a deep cut when the fish is handled or defends itself.
