The mouth of a Parrotfish is a sharp beak known as the “Pharyngeal Grille” which the parrotfish uses to scrape algae off the reef and crunch up coral.  The beak is made up of hundreds of hexagonal cells that regenerate, growing out from the fish’s gums.  As the fringes of the beak break away, new cells push forward so the parrotfish always has plenty of beak for scraping and crunching its favorite foods.
