Coastal lakes are bodies of water located near the coastline, often separated from the ocean by sandbars, barrier islands, or wetlands. These lakes can be influenced by tidal movements and may have varying salinity levels, depending on their connection to the sea. They provide unique habitats for various plant and animal species, making them important for biodiversity. These lakes often serve as recreational areas for activities like fishing, boating, and birdwatching. Additionally, they play a crucial role in coastal ecosystems by filtering pollutants and providing nursery grounds for marine life, including species like fish and crustaceans.
