Tiny architects building vast, vibrant ecosystems.
Coral reefs, the 'rainforests of the sea,' are bustling metropolises built by tiny animals called coral polyps. These polyps secrete calcium carbonate skeletons, which accumulate over millennia to form colossal structures visible from space. Reefs support an astonishing 25% of all marine life, providing food and shelter, despite covering less than 1% of the ocean floor.
