The intertidal zone is the area of the shoreline that is exposed to air at low tide and submerged underwater at high tide. This unique environment is home to a variety of organisms that have adapted to the changing conditions, including crabs, sea stars, and barnacles. The intertidal zone can be divided into different regions, such as the upper, middle, and lower zones, each supporting different types of life. These zones are important for ecological balance, as they provide habitats and breeding grounds for many marine species. They also serve as a buffer between land and sea, helping to protect coastlines from erosion. The intertidal zone is a dynamic ecosystem that plays a crucial role in the health of marine environments.
