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. This zone plays a crucial role in coastal ecosystems, providing habitat and food for many marine species. It also acts as a buffer, protecting shorelines from erosion and helping to filter pollutants. The intertidal zone is an important area for research and conservation efforts due to its biodiversity and ecological significance.
