How many rock pools are there in the UK?

The exact number of rock pools in the UK is difficult to determine as it can vary based on factors such as tidal conditions, coastal erosion, and human activity. However, estimates suggest that there are approximately tens of thousands of rock pools around the UK coastline, with a particularly high concentration found along the rocky shores of regions such as Cornwall, Devon, and Scotland. Rock pools are considered an important habitat for various marine organisms and ecosystems, including algae, starfish, crabs, sea urchins, and other coastal marine life.
