Generally brightly colored, about 60 species of Parrot Fishes swim in coral reefs around the world. They have fused teeth that form beaklike plates, giving them a parrotlike appearance. They have large thick scales that, in some species, are strong enough to stop a spear. Their coloring ranges from reds to greens, blues and yellows, as well as grays, browns and blacks. Males and females of the same species generally look quite different and, like wrasses (the Labridae family), female Parrot Fishes may change into males.
