Coral reefs are the foundation of marine ecosystems worldwide and the Bahamas hosts the third-largest barrier reef system on Earth. These living organisms — colonies of tiny polyps — build massive calcium carbonate structures over thousands of years. Brain corals, elkhorn corals, and sea fans create complex underwater landscapes that support over 25% of all marine species.
