A tidal flat ecosystem is a coastal area that is regularly exposed and submerged by the tides. These ecosystems are characterized by soft, muddy sediments that support a variety of plant and animal life. Organisms such as crabs, clams, and shorebirds thrive in these environments, taking advantage of the rich nutrients found in the sediment. Tidal flats play a crucial role in coastal protection and water filtration. They act as natural buffers against storms and erosion, while also providing habitat for many species. Additionally, tidal flats are important for fisheries and serve as feeding grounds for migratory birds, highlighting their ecological significance.
