Where do coral polyps build reefs?
Quick Answer
Coral polyps build reefs in warm, shallow, sunlit tropical seas. Major reef-building regions include the Caribbean, the Red Sea, Southeast Asia, and the South Pacific.
The Full Story
Reef-building corals thrive in warm, clear, shallow marine waters where sunlight can reach symbiotic algae living inside their tissues. They form extensive reef systems in the Caribbean, the Red Sea, the Indo-Pacific, and many island chains throughout tropical oceans. The largest reef systems are built over thousands of years by countless tiny coral polyps depositing calcium carbonate skeletons. These reefs support some of the most diverse ecosystems on Earth.
