A coral reef is a type of marine environment that is home to a wide variety of wildlife, including fish, various types of shellfish, and several other species of aquatic animals Coral reefs are generally located near the ocean’s surface, usually in tropical and subtropical regions, and are among the most diverse and productive ecosystems in the world. The majority of coral reefs are formed by colonies of tiny animals called coral polyps, which build lush, complex and colorful structures called ‘reefs’. For example, the Great Barrier Reef off the coast of Australia is the world’s largest coral reef system, and one of the seven natural wonders of the world.
These unique and vital ecosystems provide food, protection and habitat to so many aquatic species, making them a cornerstone of marine life. Additionally, coral reefs also provide many benefits to humans, such as coastal protection against storms and floods, shoreline stabilization, a natural source of medicines, and the opportunity for ecotourism and recreation.
