A lagoon is a shallow body of water separated from a larger body of water by a barrier such as a sandbar or coral reef. Lagoons can be found along coastlines and are often home to a diverse range of plant and animal species. They provide important habitats for marine life and are popular destinations for tourists seeking calm waters for swimming and snorkeling. Lagoons can vary in size and depth, with some being large enough to support commercial fishing and aquaculture activities. Overall, lagoons play a crucial role in coastal ecosystems and are valuable resources for both humans and wildlife.
