Corals are marine animals that build some of the most vibrant and biodiverse ecosystems on Earth—coral reefs. Found in warm, shallow waters, corals form massive limestone structures that support thousands of marine species, from fish and turtles to tiny invertebrates. While they may look like colorful rocks or plants, corals are living colonies of tiny polyps, feeding on plankton and thriving in sunlit seas
