coral reef organisms

Coral reef organisms include a diverse range of marine life, with corals being the foundational species. Corals are made up of tiny animals called polyps, which live in colonies and build calcium carbonate structures that form the reef. These reefs provide habitat and protection for many fish, invertebrates, and other marine species. In addition, microscopic algae called zooxanthellae live within coral tissues and are vital for their survival, as they perform photosynthesis, supplying nutrients. Coral reefs are among the most biodiverse ecosystems on Earth, serving vital ecological functions and supporting fisheries and tourism.
