How To Identify Differences Between Live and Dead Sand Dollars

It’s thrilling to see a live SAND DOLLAR at low tide half buried in the sand and water, isn’t it?

It’s also thrilling to see bleached out SAND DOLLARS washing in with the tide as well, right?

But how do you know if a SAND DOLLAR is alive or not when it is isn’t bright white?

If a SAND DOLLAR is dark in color and half buried in the sand and/or water, it is most likely still alive and we should let it stay in its place in the water.

There have been times I have posted photos of SAND DOLLARS in my bucket that were grey in color. This has been a concern to folks who were worried about whether or not I collected live SAND DOLLARS. First of all, I would never collect a live SAND DOLLAR. But I completely understand the concerns from anyone who wants to make sure nobody takes a living creature out of its habitat – especially just to take it home for a souvenir.

So here’s the way to tell if it’s alive or not… Look for the CILIA and velvety skin. These are the things that keep the animal alive and on these SAND DOLLARS… they are missing so they are not alive any more. These are now just the TESTS of the animal… like the shell (although its not technically a shell).

Do you see how the edge and surface of this SAND DOLLAR looks like it has fur?

SAND DOLLARS have short SPINES covered in CILIA (tiny hairs) so it can move along the sand and grasses. Along with those “hairs” are TUBE FEET (which look like “fur” to me too – heehee) which is actually how the SAND DOLLAR breathes.

I bet now, you can look at this next photo and see that all of these baby SAND DOLLARS in Clark’s hand are alive. After I snapped this photo, he put them back in the water.

You can see it here too, right? These need to go back into the water where they belong.

So now take a look at this next photo…. is this still alive? No. Even though this SAND DOLLAR is still gray in color, there’s no possible way it could be alive since there are no SPINES nor CILIA nor TUBE FEET. It has no way to breathe or move without those things.

Julianna shows us that the SAND DOLLAR to the left of the photo is still alive and the other one on the right side of the photo has no “fur” whatsoever. She is a good steward of the earth so she put the live one safely back in the water and she gave the other “hairless” one to her mom for safekeeping.

Most days you will see sun bleached SAND DOLLARS just like this…. Hairless! Furless! Completely “Bald”! haha

So next time you see a SAND DOLLAR while walking the beach, remember to leave it alone if it’s dark and hairy but if you are unsure if it’s alive… take your time to inspect this amazing creature before you assume it’s a “keeper”. Look for any signs of hairs, fur or velvety skin.

Now you can bet your bottom DOLLAR you’ll know when to leave those sweet living SAND DOLLARS alone…

Oh, and I took a short video of a cutie little juvie LIVE SAND DOLLAR to show you how they move those little hairs around. I hope this helps!

Uber Cute Sand Dollars to Dimes

Posted by on Feb 20, 2013 in Sand Dollar, Sand Dollar Video | 45 comments

one sand dollar piece

Uber Cuteness! If “they” named SAND DOLLARS because of the similar size of a one dollar coin piece, then I found me some SAND DIMES this morning! LOL

But then, they are even smaller than a dime.

I know some of them are still a little dark in color but don’t worry, they weren’t still alive. They were all in different stages of losing their “fur” (that’s what I call it but they actually have fine hair or cilia that cover their bodies) so that’s why they are all different colors as well. In probably one more day they will all turn white… if they don’t break apart first.

 Tara (St Louis) was showing her daughter Vivian something she just found and I got very curious because they looked so excited…seashell family tradition

So I had to ask what they found. She had a few mini shells and lots of these mini SAND DOLLARS!

Tara introduced me to the gal who found this little treasure trove of gems first this morning, Kay from Iowa. Kay’s daughter was cleaning some shells she brought back to their place yesterday and one of these little SAND DOLLARS dropped out of another shell. Wow! So Kay went back this morning about half a mile east of Gulfside City Park (Sanibel) to see if she could find a few more. Yes! She found the spot and shared this little seashell honey hole with all of us that walked by. So sweet! Kay was a little shy of the camera but she showed me the little darlings that she had in her hand…

Kate and Ken from Michigan were finding the bigger shells on the same beach.

Ken was especially happy he found that awesome baby LIGHTNING WHELK and the rich colored LETTERED OLIVE (grrrr… I wish you could see that one better because it is gorgeous). I know, that’s a gorgeous PAPER FIG too, right? It’s a keeper even though it has a tiny hole on the other side of the shell. It’s always a good day to find a PAPER FIG!

I met them just before we found the SAND “DIMES” (heehee) so they joined in on the fun too.

It was like we were finding real money out there! I actually think is was better than finding money (hmmmm, well, better than finding pocket change … let’s be honest! ;)) I got so excited to see this adorable BLING, I figured you would too. So I took a video for a CYBERSHELLING hunt for a few minutes so you could go with me. Enjoy!
