Rocky shores and rock pools
Rocky shores are unique habitats shaped by a combination of waves, tides and the type of rock present. They support a diverse mix of plants and animals which have adapted to survive the changes in exposure to water, sunlight and wind that characterise this habitat.
Rocky shores might consist of platforms, boulder fields and rock pools. Each provides habitat opportunities for different types of plants and animals … and each presents its own challenges for survival.
Case Study - A day in the life of a rocky shore resident
Many animals and plants live on rocky shores in the intertidal zone, the area between high and low tide. To live in the intertidal zone the plants and animals must be able to cope with problems of two environments. They are pounded by waves, exposed to extremes of temperature and salinity, and flooded by sea water and exposed to drying air twice every 24 hours. They also have to avoid being eaten by birds, molluscs and crabs at low tide, and by fish and other marine life at high tide.
Surviving these conditions takes special adaptations. Some animals avoid drying out by moving, burrowing or hiding under rocks and pool ledges. Most of those that are attached to the rocks and cannot move close their valves tightly until once again covered by water. Others are camouflaged and avoid predators by appearing to be something else.
