Scarids are commonly known as Parrotfishes. They are found in relatively shallow tropical and subtropical oceans throughout the world. The approximately 90 species live in coral reefs, rocky coasts and seagrass beds. With their numerous tightly-packed teeth, they rasp algae from coral and other rocky substrates, which contributes to bioerosion.
