Recognize the challenges living organisms encounter  The intertidal zone is where the land meets the water. Coastal areas are constantly changing because of the rising and falling water levels. With these variations,  16 Jul 1984 The turbulent na- ture of flow in the surf zone makes it difficult to interpret the results of these studies in terms either of the water velocity and ac-. 19 May 2010 Intertidal elevation is known to be positively related to abiotic stress. the performance of organisms (Heaven and Scrosati 2008) and plays a major Thus , we sampled 18 quadrats at each intertidal zone on each shore winter and extreme summer temperatures, freshwater rainfall, and predation create harsh conditions for organisms living in the rocky intertidal zone.

The intertidal zone is also home to several species from different phyla (Porifera, Annelida, Coelenterata, Mollusca, Arthropoda, etc.). Of course, not all organisms that rely on the intertidal zone live there full-time. Birds, foxes, raccoons, bears, and humans all happily enjoy the bounty of food found in the intertidal zone. In fact, there's a saying in virtually every indigenous coastal community that translates to, "When the tide is out, the table is set." The intertidal zone provides habitat to a variety of animal species, such as mollusks, crustaceans, worms, some species of coral and algae. The intertidal zone can be as wide as a sandy beach several meters wide or a narrow as a steeped rocky cliff. Animals that live in the intertidal zone have a variety of predators that consume them.

Organisms vary from each zone. Intertidal organisms are no different. These organisms specifically inhabit the area or zone between high and low tide along rocky coasts, sandy beaches or tidal wetlands/marshes. Some examples of these organisms include: hermit crabs, mussels, sea stars, types of algae, mollusks and many others.

In the intertidal zone the most common organisms are small and most are relatively uncomplicated organisms This is for a variety of reasons; firstly the supply of water which marine organisms require to survive is intermittent.

Barnacles, mussels, and kelps can survive in this environment by anchoring themselves to the rocks. Barnacles and mussels can also hold seawater in their closed shells to keep from drying out during low tide.

2018-01-10 2016-05-13 At the top of the intertidal zone, organisms spend more time exposed than underwater, so they will have to cope with desiccation and large temperature swings. Those pressures will be less important lower in the intertidal zone because of the protection provided by greater time underwater. organisms to live in the Intertidal zone are: their shells are hard so they can protect themselves against The harsh waves; their legs can also grab onto rocks and move fast; and they are also small enough to hide underneath rocks and other things. -Starfish 2006-03-10 Important Facts About an Intertidal Zone.
