The species grows to about 1.3 metres and has a robust, grey-green body with a conspicuous, steep bump on the forehead and fused, beak-like teeth. In schools it rams living coral with its head and rasps off the algae and polyps, producing large amounts of sand. Through overfishing the species is vulnerable. The fish is harmless to humans.
