Tidal zones are areas along coastlines that experience regular changes in water levels due to the rise and fall of tides. These zones are typically divided into different regions, including the intertidal zone, which is the area between high and low tide. Organisms in this zone must adapt to both underwater and exposed conditions, making it a unique habitat. The tidal zones are influenced by the gravitational pull of the moon and sun, which creates the cyclical patterns of high and low tides. This dynamic environment supports a variety of life, including crabs, seaweeds, and mollusks, all of which have specialized adaptations to thrive in these fluctuating conditions.
