Description
The Black surgeonfish is a surgeonfish (Acanthuridae) from reef water of the central and southern Pacific. The species grows to about 21 cm and has a deep, laterally compressed, entirely deep black with a long, pointed snout 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.
