What animals live in the intertidal ecosystem?

Answer 1

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.
