Intertidal zones are coastal areas that are exposed to air at low tide and submerged underwater at high tide. These zones are home to a variety of organisms, including crabs, sea stars, and barnacles, which have adapted to survive in this fluctuating environment. The intertidal zone is divided into different regions, such as the upper, middle, and lower zones, each supporting distinct communities of plants and animals. The conditions in intertidal zones can be harsh, with changes in temperature, salinity, and wave action. Organisms in these areas must be resilient, often developing unique adaptations like strong shells or the ability to cling tightly to rocks. These zones play a crucial role in coastal ecosystems, providing habitat and food for many marine species.
