@big.blue.sea: How many crunches can you hear? 🦜🐟 Parrotfish are some of the most important workers on the reef. Using their strong beak like teeth, they scrape algae off coral, helping prevent overgrowth and keeping reefs healthy. As they feed, they grind coral into fine sand, playing a role in shaping sandy beaches. Many parrotfish can also change sex during their lifetime, making them incredibly adaptable reef residents. #Parrotfish #ReefLife #BigBlueSea #OceanFacts #fblifestyle “Music by CreatorMix.com”
