Littoral refers to the coast or to the banks of a river. It is usually used as an Adjective , but may also be used as a Noun . The '''littoral zone''' is defined as the area between the high water and low water marks. The word is derived from the Italian ''littorale'', from the Latin ''litoralis'' from ''litus'' or ''litor-'', meaning shore. In lakes, where tides do not generally occur, other definitions of littoral must be used. The Minnesota Department Of Natural Resources defines littoral as that portion of the lake that is less than 15 Feet in depth 1. This zone is home to most of the aquatic plantlife (both rooted and floating) in a pond or lake because the high amount of sunlight reaching it allows for significant Photosynthetic Activity . The adjacency of water gives a number of distinctive characteristics to littoral regions. Water's Erosive power results in particular types of Landform s, such as Sand Dune s, and Estuaries . The natural movement of the littoral along the coast is called the Littoral Drift . Biologically, the ready availability of water enables a greater variety of plant and animal life, and the additional local Humidity due to evaporation usually creates a Microclimate supporting unique types of organisms. The littoral zone is bordered by the supra-littoral zone, also known as the "spray zone", and the sub-littoral zone, which runs to the edge of the Continental Shelf . SEE ALSO REFERENCES |
