Generally, when I think of sand dollars I think of small, brittle discs
that have dried up in the Florida sun. It is extraordinary to see one
alive and moving as is the one in this video uploaded by TheFreeRangeTexan on October 10, 2015.
It is not advised that you remove live sand dollars from the water as they are quite fragile (and I think it is illegal as well). However, this video is quite an interesting look at this unique creature!
