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, including crabs, sea stars, and barnacles, which have adapted to survive both underwater and in the harsh conditions of the open air. This zone is divided into different regions, such as the upper intertidal, middle intertidal, and lower intertidal, each hosting distinct species. The intertidal zone plays a crucial role in coastal ecosystems, providing habitat and food sources while also acting as a buffer against wave action.
