The phylum Echinodermata consists of about 7000 living species but there are a further 13,000 extinct species dating back to the Cambrian. They are basically pentaradially symmetric which means that they are five-sided, and all live in the sea. They include the sea lilies, the starfish, the sea daisies, the brittle stars, the sea urchins and the sea cucumbers.
