One major ways for the survival of all organisms is called adaptation. When it comes to Intertidal Organisms their no different. Intertidal Organisms inhabit the specific area between low tide and high tide next to the rocks on the coasts‚ marshes and or wetlands. Theses organisms can be from sea stars to types of algae and many more. As the tides come in‚ the habitat of intertidal organisms are sprayed with salt water. Then after the tide depletes‚ the habitat is exposed to the sun. It makes
