Percentage contribution of taxa density between the two estuaries at the positions across the intertidal gradient (Flat, Edge, Inner). – during high tide, the zone is being trashed by waves while during low tides, it is exposed to the sun and dry winds. Organisms in the rocky shore include: On a sandy beach, a littoral zone organism adapts to live in sand, often burrowing down into wet sand at low tide to avoid exposure. The intertidal zone is the home of seasonal variation and alternations linked to tidal cycles, making it a particularly inhospitable environment. Start studying Intertidal zones and Estuaries.

Scientists can learn a great deal from the study of these ecosystems, taking advantage of their compactness and the importance of fluxes. For organisms living in the intertidal zone, temperature is an important selective agent that can shape species distributions and drive phenotypic variation among populations. At high tide they venture forth again. 10 Ways to Protect Estuaries. Special holdfasts, such as those in kelp, prevent the waves from removing them from their substrate.
