Shown above is the low tide at Plumb Beach in Brooklyn, New York, in the early afternoon of December 10, 2018. The Moon was in the waxing crescent phase, 3 days after the new Moon. Thus this tide was not an extremely low tide. Nonetheless, because the normal tidal range here (between the daily high tide and low tide) is over 6 ft (nearly 2 m), a huge swath of the shore area has been laid bare.

This is the intertidal zone. It's covered by the sea at high tide but exposed to open air at low tide. Plants and animals living here are marine and may include crabs, barnacles, and seagrass, for example. They've learned to adapt to considerable ranges in air temperature, water temperature, salinity, and wave action, as well as to predation by both land animals and aquatic life.
