Definition of Littoral Zone

Littoral zone is defined as such a region of seas and oceans which experiences tidal and longshore currents and waves. The depth of such waves depending upon the intensity of the storm is estimated to be 5 to 10 meters. One of the characteristics of the littoral zone is that it has an abundant supply of nutrients, dissolved oxygen, and sunlight.


The littoral zone constitutes a large number of species of plants and vegetation. The presence of living things is highly dependent on the degree of the exposure of the action of the waves on the zone. Mollusks, worms, and echinoderms are present in the sandy and muddy lower layer of the littoral zone.
