What type of water is coral reefs found in?

Coral reefs are primarily found in warm, shallow waters of tropical and subtropical oceans, typically at depths of up to 60 meters (about 200 feet). They thrive in clear, sunlight-rich environments where temperatures range between 20°C and 30°C (68°F to 86°F). Coral reefs are most commonly located in areas with stable salinity and low nutrient levels, such as the Caribbean Sea, the Great Barrier Reef, and the Red Sea.
