The intertidal zone is an extremely unique region incorporating many niches in a relatively small area. The physical conditions of the intertidal zone are determined by such influential variables as temperature, light, salinity, wave action, and submersion. All of these factors combine to create the different niches for organisms. Both flora and fauna are known to exhibit vertical zonation in response to the physical conditions associated with the intertidal zone. A variety of organisms and their lifestyles will be examined including snails, crabs, kelp, and algae. Lastly, larger-scale implications will be explored including the impact of global climate change on intertidal zones.
