Archive for Dosinia
Gulfside City Park had some new beach treasures washing after a few days of heavy rain and wind across the Gulf Of Mexico. There were lots of DOSINIAS (DISK and ELEGANT) and other CLAMS lined up along the waters edge at low tide yesterday.
While walking along the water’s edge with my good friend Mary (who has an exshellent shelling eye), I noticed the water had gotten churned up again with the wind so it was a little difficult to see the bottom even in the shallow water but that’s where all the shells were washing up. In another second, I watched Mary scoop up that marvshellous PAPER FIG (in the first photo) right before my eyes… and I didn’t even see a thing. Wow! Marvshellous Mary! I need to tune up my shelling eye- haha.
I was happy to know my shelling eye wasn’t completely out of focus, I spotted this sweet SAND DOLLAR wash right up at my feet…
Beautiful sisters Bronwyn and Brenna from California have been visiting Sanibel for 20 years and were thrilled to be here this week with complete shelling eye focus.
They were finding hundreds of double COQUINAS to make shell flowers. They try to join the shell crafters at Sanibel Community House each time they are here on Sanibel so they can learn more crafting secrets. Fun!
I didn’t see many new shells washing up at Blind Pass Captiva yesterday…
I saw some interesting BLING tangled in some of the fresh weed lines at Blind Pass Sanibel and also some nice shells in the surf… so finding some goodies might be pretty productive on that beach today or tomorrow.
As the Middle Gulf beaches on Sanibel looked to be the best for this week, a little birdie told me that Lover’s Key has been pretty productive too.
Lots of folks have been already been asking for my recommendations for places to stay this winter… Here you go!
I’m still working on new dates for our iLoveShelling cruises but in the mean time, I already have some scheduled here… Join Us!
CLAMS, SCALLOPS and OYSTER shells. That’s what we’ve been seeing washed up on Sanibel beaches this week. Some experienced beachcombers might think this is a little boring since they have plenty of these bivalves and there weren’t many WHELKS and CONCHS to fill up their shell bag. But we always find interesting things and when Clark and I met Ilene, Dawn, Hudson and Ethan from St Petersburg, FL we saw they weren’t disappointed at this gorgeous evening either.
Ethan picked up an ARK SHELL with a hole in it and began telling me why certain shells drill holes in different areas of other shells. Oh wow- I just did a post on the different holes in shells last month so I wanted to know more. He told me that the further away the hole is from the hinge (what I call the “nose”), the predator mollusk is more stressed. If the predator drills near the hinge, he can get to all of the meat easily…but the shell is thicker there so it may take longer to drill. If the predator mollusk drilling the hole into the other mollusk is pretty desperate, he picks a spot that’s thinner and easier to drill but may not get much meat since the other mollusk might fight back or can slip away easier. A sign of a desperado. Thanks so much for such cool information, Ethan! BTW, Ethan teaches classes about Paleoceanography .
If I didn’t put you asleep on that explanation and you think this stuff is interesting too, here’s a photo of what I’m talking about. See the DOSINIA on the left with the perfect hole in the nose area and then look at the hole in the desperate CALICO CLAM with the hole in the middle of the shell. Why so desperate Mr. Murex? Okay, I’m not positive it’s a MUREX that made the hole but in my humble opinion, it sure looks like an OYSTER DRILL hole (part of the MUREX family). Take a look at my other post What Makes The Different Holes In Seashells?
Okay, lets get back to the beautiful shells… While we were all talking near Lighthouse Beach, Ilene showed me her pretty DOSINIA then I saw Hudson reach down and pick “candy” (juvie HORSE CONCH) right out of the shells at our toes. Clark then made a scoop in the water and pulled out a TRUE TULIP then gave it to them. Hmmmm, the shells looked like they were starting to come in but it was getting too dark to see.
Dawn just posted on iLoveShelling Facebook page this morning that they found all of these shells at Lighthouse Beach. Yes! The WHELKS and CONCHS are finally coming in… not that we were feeling desperate or anything. LOL
Thanks for posting, Dawn! Looks like we are going to be heading to Lighthouse Beach today to find some mermaid treasure but I’m really looking forward to our iLoveShelling cruise to Cayo Costa tomorrow with Captiva Cruises.

i heart seashells. Shells have a way of talking to us, don’t they? They make us feel deeply connected to the vast sea and pull us towards it. This PONDEROUS ARK shell washed up at my feet with a heart carved in it. Awwwwe, so sweet! I love you too! But hmmmm… other than being an oh-so-sweet message from King Neptune, how did this happen?
We see natural holes drilled in all sorts of shells, so it’s time to find out how they are made. The hole in this SHARKS EYE tells me a little secret of what happened to its life. The clue? It has a perfect countersunk borehole with a beveled edge twice the diameter as the inner diameter. Because of the shape of that hole, you can bet that he was eaten by another SHARKS EYE! OMG They are cannibals!
We have to guess what happened to this next guy because it looks like a fellow predator SHARKS EYE started carving up his next meal but stopped before he tasted victory.
By looking at the hole in this DISK DOSINIA, I’m going to assume that a SHARKS EYE made a meal out of this guy too.
Geez, SHARKS EYES have a smorgasbord of choices for their buffet. Looks as though they like BUTTERCUP LUCINES too.
A straight hole with only a slight beveled edge like this LADY-IN-WAITING VENUS CLAM …
…was most likely drilled by some sort of MUREX… like GULF OYSTER DRILLS. Aha! That’s why they are called “DRILLS”!
The grooves in these CROSS BARRED VENUS CLAMS and TRANSVERSE ARK aren’t the handiwork of the SHARKS EYE or DRILLS. These grooves were most likely made by a BRISTLE WORM. It uses a rasping technique with its bristled body while secreting acid to etch a groove in the shell to make a nice cozy place to rest.
After Shellabaloo, she sent me this sweet CROSS-BARRED VENUS shell with a smiley face on it (made by a BRISTLE WORM). I keep it by my desk!
She also found a “K” on a CROSS BARRED VENUS…
Lisa was so thoughtful, she gave it to another Shellabaloo-er… Kendra. K for Kendra!
So let’s get back to that heart I received from King Neptune … these bigger holes most likely were drilled by a STIMPSON CHIMNEY CLAM. Oh, What? You’ve never heard of a STIMPSON CHIMNEY CLAM before? LOL Well, neither had I before I got so curious about what made that heart shape and found out that two separate drilled incidences by these clams are the most likely culprit. When I find a STIMPSON CHIMNEY CLAM, you will be the first one to know about it and I will post a photo. I already have an appreciation for them since they are quite the artists!
I just assumed that a shell with lots of little holes in like this was just from regular wear and rear by the salt and wave action… like when you wash and wear your favorite shirt too many times. One day, you’ll start to see holes in it! But some times shells that look like this tend to be “holey” because BORING SPONGES have invaded it as a living space.
I’ve always been drawn to shells that have holes for stringing them for crafts….
For gift tags…
And I always love to see someone string them for jewelry…
I would have never known where to start finding information on these cool holes in shells if Lisa from Shellabaloo 5 (OMG I just realized… both Lisas from different Shellabaloos are fascinated with holes in shells too! Ha! They need to know each other, wouldn’t you say?) anyway… I wouldn’t have known there was such a term as “Shell Bioerosion” and such if she hadn’t shown me where it was in this book Living Beaches of Georgia and the Carolinas .
There’s all kinds of fun to be had in exploring the common shells if you just give them a chance. They may even tell you a secret!
