Watery Wednesday

The Common Sand Dollar
Echinarachnius parma

Photo taken at the Monterey Aquarium, Monterey, California of live sand dollars.

By the time you find a sand dollar washed up on the beach, this fragile disk is the skeleton of a marine animal. It is missing its velvety covering of minute spines and appears somewhat bleached from the sun and is hard to believe it was once alive. Sand dollars are from the class of marine animals known as Echinoids, spiny skinned creatures. Their relations include the sea lily, the sea cucumber, the star fish and the sea urchin.

I got this from an article on line which was written by a lady by the name of Cheryl Page.

You can read more of her article if you click right here.

I read on the sign next to the exhibit that in quiet waters these animals stand on end, half buried in the sand. Where waters are rough, sand dollars hold their ground by lying flat - or burrowing under. Adults also fight the currents by growing heavier skeletons. Youngsters swallow heavy grains of sand, which weight them down.

You know, I've always had a tremendous affection for Sand Dollars and I have no idea why!

That's gorgeous photo.

Oh, really cool photo, too!

What an unusual sight. Presumably they have no intelligence and ye they know when to lie doggo! Fascinating!

We have large beds of live sand dollars in the tide flats of Useless Bay, Whidbey Isalnd.

Hi Denise, I have been following your posts on the Monterey Aquarium. I am so impressed of the beauty and colors of the underwater plants and flowers. This one is no exception at all. I have been there probably 10 years ago and I only have vague visions.

Thanks for your wonderful comments. It is such a pleasure.

There's so many of them - very cool post - I have some sand dollars that a friend gave to me from Florida, I think.

Tabib said...

Looks like a coins.

Cool photo of the sand dollars.

matron said...

I have never heard of or seen sand Dollars so this is an interesting new experience for me.They are so decorative,I am truly amazed.

Denise said...

Richard @ The Bewildered Brit, I've rather liked them too Richard.

Splendid Little Stars, easy to spend a whole day there, and maybe two.

J Bar, happy you enjoyed them. I've seen them before but not for many, many years and not live ones.

marina, they are aren't they? Me neither.

Carletta, I haven't seen one alive either.

Guy D, how kind, thank you :)

Rinkly Rimes, I agree, it makes you wonder doesn't it how they figure these things out. Clever little things.

Linda Reeder, I never knew that. How interesting.

Ebie, me too. Absolutely amazing, a whole new world under the ocean.

Tricia, thank you. The only time I ever see them are the ones just like yours probably when we went down to Florida.

Tabib, I agree, they do look like coins.

Strawberry Jam Anne, I'm glad I was able to introduce you to them Anne.

Cezar and Léia, me too Léia, me too.

eileeninmd, thank you very much.

Denise said...

matron, I always feel the same way when I come across something I have never seen before.

Patty said...

I enlarged the photo, how beautiful they look alive. Thanks for sharing. By the way, that comment from anonymous, I think I would delete it, hard to tell what it's saying.

Viola said...

Such wonderful creatures! I have never seen such before! :)

Mary said...

Wow..they look great like that! The colors are pretty.

CambridgeLady said...

Good to see them alive :)

diane said...

I haven't ever seen those sand dollars. They are very interesting sea creatures. Good shot too.

happilyretired said...

When I saw the photo, I marveled at how many sand dollars you'd found ... then I read you've seen them at the Monterey Aquarium ... Isn't that a MARVELOUS place to visit? Wonderful watery post ;-)
Hugs and blessings,

Denise said...

Patty, aren't they just so beautiful? I wondered about Anonymous' comment and went over to Google translate. I found that it was in Chinese and I was so happy that they translated it for me. I got the gist of what he/she was saying and basically the message was telling me they were looking forward to further posts. I found out how to say "thank you" in Chinese and that was my answer in those characters. Appreciate the concern. I am trying to use Google translate time permitting for our overseas friends.

Viola, I've only seen ones sold in stores but that's been years ago.

Mary,I agree.

CambridgeLady, indeed it is.

diane, they are and thank you so much.

happilyretired, the aquarium is fantastic. So many interesting things I had never seen before.

OK..there is just something about both the lovely Sand Dollar & the Sea horse I've always found so magical! Honest..when I was a kid, (we collected sea shells right) but really, this is so beautiful Denise.. Eileen on(just nature photos) posted one on Dolphins the other day..another beautiful ocean creature. Anyway- hope you have a great day- thank you for you wonderful visit and encouraging words! Regina-

Kay said...

Gosh! I've never seen LIVE sand dollars before. This is fascinating.

Denise said...

Kilauea Poetry, well, I know what you mean. I saw Eileen's photos of the dolphins and I absolutely agree. Always love to visit Regina. Have a great week.

Kay, this was my first time seeing live sand dollars too. I agree, they are fascinating.

Thanks again for visiting everyone. Sure do appreciate it.
