Tidal flats are coastal areas that are exposed during low tide and submerged during high tide. They are typically found in estuaries and along shorelines, where the land meets the sea. These regions are characterized by soft, muddy, or sandy sediments that support various forms of life, including plants and animals. The unique environment of tidal flats creates habitats for many species, such as crabs, clams, and shorebirds. These areas play a crucial role in the ecosystem by providing feeding grounds and breeding sites. Additionally, tidal flats help filter pollutants and protect coastlines from erosion.
