The Identified Organism in the Intertidal Zones
Life abundant and diversity differs from one zone in the sea or ocean to the other. The lower intertidal has the most diverse number and type of goods and services. The physical stresses are the primary factors that influence the size, number and type of organisms in each of the zones. The organisms are exposed to high tides and large temperature. Four zones are identified as spray, high intertidal, middle and low intertidal zones. The spray zone extends from point where the spray and storm waves reach and the point where average high tides reach. The zone is dry and the key species identified in this zone include small barnacles, periwinkles and ribbed limpets.
High intertidal extends from the point where the average high tide wave reaches and to just below average sea level. The key species in this zone include acorn barnacles, shore crabs, black turban snail and sea lettuce and rockweeds. The middle intertidal zone extends from the average see level to the lowest tides. The zone is rich in diversity and number of organisms. The algae densely cover the zone, which is the primary source of food in the zone. The key species in the mid intertidal zone include California mussel, giant green anemone, and sea palms and sponges among others. The low intertidal zone is characterized by the low tides, and relative low temperatures and sun light penetration. The number and type of animals in this zone is relatively more than it is in the other zones. The key species in the zone include gumboot chiton, ochre sea star, crabs, blue top snail, feather boa kelp, and sponges among others.
