Several animals are visible on this block, including a white sea urchin, a few feather stars attached near the rope handle and a tiny white snail crawling near the urchin. All of these animals probably crawled onto the rock after settling elsewhere, but there were also several barnacles attached to it which must have arrived as larvae.
