Sea urchin. Spiny black sea urchin washed up on a beach. Sea urchins are bottom-feeding creatures of the phylum Echinodermata. These animals are characterised by their unusual five-fold radial symmetry (not seen here). Sea urchins have spiny shells which protect them from predators. From pores in these shells emerge the movable podia (feet), usually with suction cups, which enable the sea urchin to move. Photographed in Barbados.
