Parrotfishes (Scaridae) are vibrant, reef-dwelling fish known for their bright colors, beak-like teeth, and unique role in coral reef ecosystems. They use their fused teeth to scrape algae off coral and rocks, contributing to reef health. Parrotfishes are found in tropical and subtropical oceans worldwide.

Scaridae, commonly known as parrotfish, are primarily found in tropical and subtropical oceans around the world. They are distributed across the Indo-Pacific region, the Atlantic Ocean, and parts of the Red Sea and the Caribbean Sea. Key regions include the Great Barrier Reef in Australia, the Hawaiian Islands, and coral reefs throughout the Indian Ocean and the Pacific Ocean.

Parrotfish inhabit coral reefs, rocky coasts, and seagrass beds. These environments are characterized by warm, tropical waters with temperatures typically ranging from 23°C to 28°C (73°F to 82°F). They thrive in areas with abundant coral growth which provides shelter and food resources.

Parrotfish play a crucial role in coral reef ecosystems as herbivores. They graze on algae that grow on coral surfaces, helping to prevent algal overgrowth which can smother coral reefs. Additionally, their feeding behavior contributes to bioerosion, as they scrape off pieces of coral and excrete sand, helping to maintain reef structure and health.
