Coral reefs

Coral reefs are vibrant underwater ecosystems formed by colonies of tiny organisms known as coral polyps. These polyps secrete calcium carbonate to build hard skeletons, creating the structure of the reef. Coral reefs are typically found in shallow, warm waters of tropical and subtropical oceans, where they flourish in sunlight. Coral reefs support a remarkable diversity of marine life, serving as habitats for thousands of species, including fish, mollusks, crustaceans, and other marine animals.
