Littoral Zone Organism

The littoral zone (also called the intertidal zone) is the area where the sea and land meet, in between the low and high tide zones. The littoral zone is vertically divided into vertical zones: spray zone (usually dry), high tide zone (wet during high tide), middle tide zone (alternating between wet and dry), and low tide zone (usually wet). This intricate marine ecosystem is found along coastlines, and is plentiful in oxygen, nutrients, and many different organisms, including isopods, mussels, crabs, sea anemone, sea stars, barnacles, and hermit crabs, such as the one shown in the picture here . Much of this environment is washed by tides every day, so organism that live are usually adapted to daily changes in moisture, salinity, temperature, and water turbulence.
