Infralittoral Zone

The lowest zone is the part of the shore exposed only at the lowest tides. It is made up of the Infralittoral Fringe and Infralittoral - (Sublittoral) - zones.

Because of the longer submersion period, organisms here do not have to be as sturdy and adaptive. This is why more organisms make this zone their home. A variety of algae grow here like surf grass and sea palm and provide shelter for many small animals who find plentiful food in this zone.

This area includes the sub tide zone and normally underwater. It is only exposed by a negative tide and covers approximately -0.1 to -1.6 feet. The organisms here can only tolerate slight exposure from the air or sun.
