Reef-building corals

Reef-building corals, also known as hermatypic corals, are marine organisms that create coral reefs, vital ecosystems found in warm, shallow waters. They are made up of tiny polyps that live in colonies and secrete calcium carbonate, forming the hard structures of reefs. These corals have a symbiotic relationship with microscopic algae called zooxanthellae, which provide them with energy through photosynthesis. Coral reefs support diverse marine life, protect coastlines from erosion, and contribute to fishing and tourism. Sadly, they are threatened by climate change, pollution, and other human activities, making their conservation crucial for ocean health.
