The shore environment that becomes exposed with the falling tide is known as the intertidal zone and it is one of the harshest environments in which to survive. On the shore, different plants and animals have had to adapt to a huge range of environmental stresses, like drying out in the sunshine. All are highly specific or specialised as to where they can grow, so often clearly defined zones are apparent on the shore. This is known as zonation. Rockpooling is a great way to begin exploring our amazing marine environment.
