The term "intertidal" refers to the area of the shoreline that is exposed to air at low tide and submerged underwater at high tide. This unique zone is home to a variety of organisms that have adapted to the changing conditions, including crabs, sea stars, and barnacles. The intertidal zone is divided into different regions, such as the upper, middle, and lower intertidal, each supporting distinct communities of life. Intertidal ecosystems play a crucial role in coastal environments, providing habitat and food for many species. They also help protect shorelines from erosion and serve as important areas for nutrient cycling. The health of intertidal zones is vital for both marine life and human activities, such as fishing and recreation.
