2. What are the different regions of the Intertidal Zone?
The Intertidal Community is composed of several different regions that differ depending on tidal and wave exposure and life within the zone. The different conditions in each region allow for a great diversity of marine life. This can also lead to a competition among organisms for limited space on the rocky shore.

The Intertidal Zone is divided into six specific regions:
- The Black Zone (or Splash Zone)
- The Periwinkle Zone (or Splash Zone)
- The Barnacle Zone (or Upper Zone)
- The Rockweed Zone (or Middle Zone)
- The Irish Moss Zone (or Lower Zone)
- The Kelp Zone (or Subtidal Zone)
Note: For more information about these zones and the organisms found in each zone see OMP's DOCE website.
