Rocky Shores around the world

Rocky shores are found where the sea meets the land.  A rocky shore is an intertidal area on seacoasts where solid rock predominates. are biologically rich environments, and make the ideal natural laboratory for studying intertidal ecology and other biological processes  Rocky shores are areas of bedrock exposed between the extreme high and extreme low tide levels on the seashore.  These ecosystems are found all over the world.  Many animals and plants live on rocky shores in the area between high and low tide called the intertidal zone.   Rocky shores dominate a large proportion of the world’s coastlines and although

there are regional differences in their form and function they all play important roles within their local marine ecosystem.  Rocky shores are very variable in form. Bedrock shores are common on the wave

exposed coasts of all continents but are also found in sheltered marine inlets and some estuaries. Depending on geological formations and oceanographic processes, they range from vertical cliffs to gradually sloping or wave-cut platforms. In many tropical regions they are formed from raised fossil coral reefs. The rock may be pitted, cracked and creviced and sometimes forms rock pools, overhangs, gullies and caves. Some shores are dominated by boulders, particularly in arctic and cold temperate regions where they are often of glacial origin. Many of these boulder shores are very porous, with interstitial spaces that can go deep below the surface.  Intertidal boulders in other regions are normally lying on firm sediment without deep gaps.  These ecosystems can be found around the world ranging from the United States, Canada, Africa, Australia, Pacific Islands, and European countries, New England is also well known for the abundance of rocky shores.
