intertaidal zone

The intertidal zone, also known as the foreshore and seashore and sometimes referred to as the littoral zone, is the area that is above water at low tide and under water at high tide, This area can include many different types of habitats, with many types of animals, and numerous species of coral. 

                                  

 Peritidal zone is similar but a somewhat wider zone, extending from above the highest tide level to below that of the lowest tide level. The intertidal zone is also home to many several species from different taxa including Porifera, Annelids, Coelenterates, Mollusks, crustaceans, Arthropods, etc. Wateris available regularly with the tides but varies from fresh with rain to highly saline and dry salt with drying between tidal inundations.
