 Rock Pools

Rock pools are found at all levels on the shore but the largest ones are generally found at the lower levels of the shore. The depth of rock pools ranges from a few centimetres to a few meters, but all must contain some permanent water to designate as rock pool. The volume of rock pools ranges from a few litres to a few cubic meters with weekly to monthly variations dependent on season, volume, surface to volume ratio and the amount of vegetation. The environmental conditions are most suitable in the rocky pools in comparison to other habitats of littoral zone. The forms found in these pools are sponges, hydroids, sea anemones, bryozoans, copepods, snails, limpets, mussels and tunicates.
