The species grows to about 30 cm and has a greenish to brownish body that hides well among vegetation. Unlike many reef-dwelling parrotfishes it lives in coastal bays and deep lagoons with seagrass beds and dense algal beds. Unlike its relatives with a true parrot beak it has separate, partly overlapping teeth. As a herbivore it grazes seagrass and algae. The species is harmless to humans.
