Description

The spotted sawtail is a sawtail surgeonfish (Acanthuridae) from temperate reef waters of the western Pacific, around Australia and Japan. The species grows to about 45 cm and has a deep, grey-brown body with fine dark spots and a row of sharp, bony plates on the tail base that act as scalpels. As a reef-dweller it grazes algae from rocks and coral in groups. The tail plates can cause deep cuts when handled; otherwise the fish is harmless to humans.
