What is unique about the intertidal coastline ?

 The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals.

Explanation: The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.
