Time Lapse Sand Dollar moving accross the sand

Uploaded by mrjustin5 on Nov 24, 2006
This is some Time Lapse video I shot of a very active Sand Dollar moving across the sand in the afternoon. It has a clump of sand on top of it. I have always seen these when I was a kid, but now my fascination with them has really been sparked. The eat plankton and are related to Sea Urchins (they eat sea plants). Some of these Sand Dollars move in a straight line, some go in a circle around and around. Others zig-zag back and forth. I know they seem to have an exoskeleton but WHAT are they? I cant seem to find a lot of detailed information about these creatures and their habits online. Has anyone ever seriously studied the behavior of these creatures? I don't know if they have a brain, but without one, how do they make decisions? Some seem to bury themselves in the sand.

(We actually had a dead sand dollar in our fishtank once. It was my favorite thing in the tank)

@LustX sand dollars are live things but if you ever hear someone talking about a sand dollar they found at the beach, most likely they're talking about the dead ones that wash up on the shore that have something that looks sorta likes flower thingy
