Description

The scalpel sawtail is a sawtail surgeonfish (Acanthuridae) from temperate reef waters of the northwest Pacific, off East Asia. The species grows to about 50 cm and has a deep, grey-brown body 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. The tail plates can cause deep cuts when handled; otherwise the fish is harmless to humans.
