The Reef is a vibrant underwater ecosystem found in oceans around the world, primarily in tropical and subtropical regions. It is made up of coral structures that provide habitat for a diverse range of marine life, including fish, mollusks, and sea turtles. Coral reefs are formed by tiny animals called coral polyps, which secrete calcium carbonate to build their skeletons. These ecosystems are crucial for maintaining biodiversity and supporting fishing industries. They also protect coastlines from erosion and provide opportunities for tourism and recreational activities like snorkeling and diving. However, coral reefs face threats from climate change, pollution, and overfishing, making their conservation essential.
