A lagoon is a shallow aquatic ecosystem isolated from larger water bodies by natural barriers like reefs, islands, or narrow strips of land. These unique environments are typically categorized as coastal or atoll lagoons, with some occurring along mixed sediment shorelines. The distinction between lagoons and estuaries can be blurred, as they share similar characteristics. These captivating water features are found in abundance along coastlines across the globe, contributing to the diverse tapestry of coastal landscapes and ecosystems.
