The Upper Intertidal zone is the area of the shoreline that is exposed to air during low tide but submerged during high tide. This zone experiences harsh conditions, including strong wave action, temperature fluctuations, and varying salinity levels. Organisms in this zone must be adapted to survive both wet and dry conditions. Common inhabitants of the Upper Intertidal include barnacles, mussels, and seaweed. These organisms often have specialized adaptations, such as strong shells or the ability to cling tightly to rocks, to withstand the challenges of their environment. This zone plays a crucial role in coastal ecosystems, providing habitat and food for various marine species.
