Thrift and certain lichens belong to those land organisms that can live amongst the cliffs. Even those organisms that are common on land are confronted with difficulties when they try to colonize rocky shorelines. To survive, they must endure being exposed to seawater. Examples of such terrestial organisms are lichens, certain flowers, mites and insects. Usually they are found in the upper regions of the beach. There are much fewer terrestial organisms found on the shoreline that are exposed to saltwater spray, than there are Marine organisms that are exposed to the air. Page 21 of 52
