Each colony is composed of multiple polyps called corals—animals with tentacles around a mouth at one end and sac-like bodies at the other that attach to a surface and secrete calcium carbonate for protection. Over thousands of years, these secretions accumulate to form habitats that support about 25% of marine species, even though they cover less than 1% of the ocean floor.
