One of the myriad Sally Lightfoot Crabs that live among the rocks along the often turbulent, windy shore just above the limit of the sea spray. The crabs feed on algae and, like many other saltwater crabs, sometimes consume plant matter and dead animals. They are a quick-moving and extremely agile saltwater crab.
