ocean coral

Ocean coral, often referred to as coral reefs, are diverse underwater ecosystems made up of calcium carbonate structures secreted by corals. These vibrant communities provide habitat and sustenance for a vast array of marine life. Coral polyps, tiny organisms related to jellyfish and sea anemones, form the building blocks of these reefs through a symbiotic relationship with photosynthetic algae called zooxanthellae. Coral reefs are crucial for coastal protection, biodiversity, and fisheries, but they face threats such as climate change, pollution, and overfishing, highlighting the urgent need for conservation efforts.
