Creature of the sea I

A while ago i spent two wonderful weeks of holidays on the beautiful island of Mauritius with my girlfriend. One day we went down to the beach to gather some peaces of dead coral, shells and suddenly i came across this weard thing. It used to be a sea-hedgehog and got washed ashore. There are many of these black volcanic stones along the beaches of this island that are wonderful to take pictures of. I placed the sea-hedgehog's skeleton on one of them and "click", that's the result of it.
Hope you like it.
Please watch it in full view for the details.
