The Intertidal Zone

Tidal Zones The intertidal zone is the area of the shore that is submerged during part of the tidal cycle. The lowest parts of the intertidal zone are only exposed to air for a few days a month The highest parts are only submerged for a few days a month

Low Tide Zone This area is only exposed at low tide. Rich in kelp and sea weed Animals here are rarely exposed to harsh sunlight, but often exposed to predatory fish and rough waves Organisms here are adapted to resist wave action

Mid Tide Zone Submerged during every high tide, exposed during every low tide Plants are rare here, most organisms are animals like clams, starfish and crabs Animals are adapted to changing from water to air every day (clams and anemones seal up to preserve moisture)

High Tide Zone Only submerged during high tides Land plants such as mangroves may live here Populated by animals highly resistant to drying out Clams and anemones seal themselves up to preserve moisture Crabs can breathe air for hours
