The intertidal zone -- the area between high and low tides -- is a harsh and unforgiving habitat, subject to the rigors of both the sea and the land. After an aquatic juvenile stage, they glue themselves to rocks and remain there for the rest of their lives. Sub tidal organisms, as a rule, have not evolved for intertidal life and tend to do very poorly there; conversely, intertidal organisms are often unable to survive the predators found sub-tidally. As was mentioned, the species richness is high, a … The intertidal zone, also known as the foreshore or seashore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range).This area can include several types of habitats with various species of life, such as seastars, sea urchins, and many species of coral. The assemblage of algae and animals that live there is often very unique and adapted for a challenging set of living conditions that come with the partial exposure.

In fact, there's a saying in virtually every indigenous coastal community that translates to, "When the tide is out, the table is set." Most of the marine organisms are ectothermic and need the warmth from the environment to survive. Some organisms that occupy this zone are Mussels, Aggregate Anemones, and Red Alga, to name a few. Small fish will often be washed into rock pools during high tide and must wait until the next tide to return to the ocean. Many anemones like the green anemone, Anthopleura xanthogrammica, get their color from photosynthetic algae that live inside them, providing them with an additional source of food. The three major types are: Rocky shore, sandy beaches, and mud-flats. The lower intertidal zone is mostly submerged underwater most of the time and is only exposed when it is low tide. Living organisms such as fish depend on the oxygen for survival while photosynthetic plants cannot make food without carbon dioxide.
