How do coral reefs grow from tiny polyps?
Quick Answer
Coral polyps build reefs by secreting calcium carbonate skeletons. Over time, many generations of polyps accumulate into large reef structures.
The Full Story
Corals are tiny animals called polyps that live in colonies. Each polyp secretes a hard calcium carbonate skeleton beneath and around itself. As the colony grows and older polyps die, new polyps continue building on the existing structure. Reef formation is slow but can continue for thousands of years under the right conditions. Symbiotic algae called zooxanthellae help supply the energy that makes this growth possible in clear, shallow waters.
