Welcome to one of the world’s most unique ecosystems, the Rocky Intertidal Zone. This vast expanse where land meets sea supports a thriving body of marine organisms all adapted to live under the harsh environmental pressures characteristic of this area. Dictated by the gravitational pull of the moon and sun, the tides predictably flow in and out creating a low, high, and middle tidal zone. Each of these zones maintains a unique community waiting for your students to explore and discover what it means to adapt to their environment.
