The Intertidal Zone
Littoral Zone Animal Printouts

clamThe intertidal area (also called the littoral zone) is where the land and sea meet, between the high and low tide zones. This complex marine ecosystem is found along coastlines worldwide. It is rich in nutrients and oxygen and is home to a variety of organisms.

Intertidal Zone

An Inhospitable, Changing Environment:
Much of this inhospitable environment is washed by the tides each day, so organisms that live here are adapted to huge daily changes in moisture, temperature, turbulence (from the water), and salinity.

Vertical Zones:
knobbed whelkThe littoral zone is divided into vertical zones. The zones that are often used are the spray zone, high tide zone, middle tide zone, and low tide zone. Below these is the sub-tide zone, which is always underwater.


Predators:
Animals that live in the littoral zone have a wide variety of predators who eat them. When the tide is in, littoral organisms are preyed upon by sea animals (like fish). When the tide is out, they are preyed upon by land animals, like foxes and people. Birds (like gulls) and marine mammals (like walruses) also prey on intertidal organisms extensively.
