In Acadia National Park, Maine, the tides change as much as 12 vertical feet.  Life here adapts to the timing and the twice-daily overhaul of the local environment.  Mussels and sea stars stay deep, close to the permanent tide pools.  Barnacles and seaweed cling to rocks, sealing in moisture when the water recedes.  Snails graze the exposed plant life, and birds, raccoons, and other animals cruise the pools when the tide is low, looking for any feeding opportunities they can find.
