I posted some Macro photos in a post called Abstract Fun Questions It is part of the weekly Photo Challenge. The sea urchin and sand dollar were the easiest. Two other a little harder (you can check them out and make a guess). The one that remains a complete mystery is this one. Just for fun I am posting again.
Yes they are edible and smaller than a jelly bean. But can you identify what this is?
I promise to reveal the answer to all who comment.
