Low-intertidal Zone

Imagine you're trying to keep your houseplants alive during a particularly dry season, and you can only water them during the rare moments it rains. This is similar to the low-intertidal zone, where marine organisms can only access water during the lowest of low tides. Just like your plants depend on those sparse rain showers to thrive, the creatures in the low-intertidal zone rely on the brief periods when the sea washes over them, providing the necessary marine environment for their survival.
