    Hi there

    While diving in Mexico I saw a couple of these things, our guide told us it was an animal, but didn't know the name, and I can't manage to get any hits when googling all sort of words =)
    So, anyone knows what this is?

    which funny enough is what most people recognize them as...
    rather uncommon to see them or pictures of them alive picture below where you can see all of the little feet that they use to move food towards their mouths and to get around. Same way a sea urchin does

    Yes, the rare and elusive Sand Dollar that lives for the most part beneath the sand. Another reason to stay off the bottom... even sandy bottoms.
