Black sea urchins are found all around the rocky shores of Greece and are members of the phylum echinodermata [from the Greek meaning spiny skin] and are related to starfish.  The similarity becomes apparent when you look at the beautiful shell and see the lines radiating from a central point.  See Wikipedia for more information about these creatures.
