@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
I dive a lot in Monterey. There are immense fields of these things as far as the eye can see and beyond in 15-20' water along sandy beaches. The numbers of these things are truly astonishing.
Really they don't bury themselves, they just can't climb over stuff so they just go right through it. Btw how long did this take to film? They move so slow you hardly notice it.
Today I went to the beach, and there were sand dollars everywere. I never knew they were alive, and soon became intrested in them. I watched them move. I watched how they filter feed in the water by opening and closing their mouth. I even found a dead one, in were I broke it open to see what was inside. They have some kind of thick, light red blood in their middle, and they have a soft, white star right in there middle! It was pretty cool. Infact, I think sand dollars are kinda cute!
When I was a kid my family and I collected them from the waters at the beach and put them in the sun to dry and then bleached them white. Now that I'm an adult I feel real guilty that we killed hundreds of them for nothing. I was a stupid kid and didn't realize they were living animals that I was killing, and for nothing other than to have a bunch of white things to show off or sell for a few dollars. I feel real bad about it now.
They don't technically have a brain, they have a mess of central nerves. And I can't remember exactly their "exoskeleton" is made of, but I believe it is the same as starfish... They are actually in the same class as starfish... They have radial symmetry (as you can easily tell). Their body is covered with tiny hairs called cilia, which grow larger and more identifiable on the bottom. They move around rather randomly, however the cilia move food particles down groves to their mouth.
yeah we sat some on some concrete in shade at condo, and they move. lol first time i found that out, was so cool. you can bleach them and kill them, which turns them white, and basically washes away all those little hairy legs on the underside
I think the holes in the top are for bringing in water to turn into breathable oxygen like gills. idk for sure.
They are not suspension feeders, but rather graze on the algae which is attached to the individual sandgrains. Those tracks on the oral side contain mucous which moves the sand grain toward the central hole. Therein is a 5 part toothed structure, called Aristotle's lantern.Think of how you obtain corn kernels from the cob, and that is rather like how the sand dollar gets the algae bits off each sand grain. Wonderful video - thank you SO much!!!!!!!!
very cool video! They are related to Sea Urchins and Sea stars - they are classed as 'irregular urchins' and are suspension feeders. They do move, and they do bury themselves in the sand.
To answer your question about study of behaviour, yes - people do (I am one of those people currently - but just starting my research)
I honestly had no idea Sand Dollars were puffy looking creatures, and had color. I thought that the white part that washes up on the beach (sold in stores etc) was it's skeleton or a dried up Sand Dollar 0_o
Thank you! I shall soon have some more timelapse stuff here. It shall look a lot more clearer now that Youtube has a "Watch in High Quality" option! Thanks for the comment!
This was taken at Pismo Beach in 2006. At certain times during the year, Sand Dollars love to come up and skim around on the top of the sand. Then you can watch them start to bury themselves as they dive down under the sand. Thanks for the comment!
OH Wow. This is great. I have placed sand dollars on my hand and they do move. I had no idea they could move in a direction that would help them get back in the water. TEll us... did it go towards the sea or not? He looked like he knew what he was doing. Great job. Thanks.
johnknoefler, I am sorry for the late reply. These sand dollars eat plankton if I remember correctly. Or perhaps Algae, I am not 100% sure. Some zig-zag through the sand, skimming along, others go in circle, some go in just one direction. And to answer the other part of your question - yes, the do bury themselves, I've seen it. They have little prickly hairs that move in unison to get around and they change the movement to literally dive down under the sand.
@mrjustin5 Amazing! thanks for the post, though i stumbled on this vid a few years late! Things like this certainly broarden the mind, look how much different sea creatures are from land life! man this is great!!!
i happen to be studying for a biology final tomorrow...sand dollars are in the phylum echinodermata, class echinoidea (along with sea urchins, as you mentioned). hope that helps.
you should consider adding some music from the new youtube audioswap feature. there's a whole bunch of interesting tracks buried in the 'other' category.
you'd think this would be a boring video, but it's not.
...think you could make a longer one?
(We actually had a dead sand dollar in our fishtank once. It was my favorite thing in the tank)
