Definicija: 1) The area between land and sea which is regularly exposed to the air by the tidal movement of the sea. Marine organisms that inhabit the intertidal zones have to adapt to periods of exposure to air and to the waves created by wind, which makes it the most physically demanding of the marine habitats. 2) The shore zone between the highest and lowest tides.

Definicija: 1) Območje med kopnim in morjem, ki je ob plimovanju, ko se morje umakne, redno izpostavljeno zraku. Morski organizmi, ki naseljujejo območja plimovanja, se morajo prilagoditi življenju na zraku in valovom, ki nastanejo zaradi vetra. Zaradi tega je to življenjsko okolje med vsemi morskimi habitati fizično najbolj zahtevno. 2) Obalno območje med plimo in oseko.
