i Love Learning About Pen Shell Pearls
Posted by: | Comments
While talking to Gary on our iLoveShelling shelling cruise last week, he told me about four huge HORSE CONCHS and other great shells he and his family Cameron, Mary and Lauren found on Sanibel during their visit from Nashville. Amazing!
He also asked me if PEN SHELLS could make PEARLS and I immediately answered “It’s rare to find the PEARLS washed up on the beach but… Yes they can!”. He found something that looked like a PEARL inside a PEN SHELL while looking for other shells like TRUE TULIPS which can hide or get trapped inside them (CLICK HERE for a video to show this). Of course I had to see it.
If you look closely, you can see a milky circle on the inside of his shell and at about “9 o’clock” on that circle (the MOLLUSK’s muscle scar where it was connected to the shell) you can see a little ball on the shell. That’s a PEARL.
This type of PEARL is called a BLISTER PEARL. Cool! BLISTER PEARLS are attached to the shell so mostly likely the PEARL would break if he tried pop it out to make any jewelry from it but it’s still cool for him to have seen it…. questioned it…. and ask me about it so we can all learn more.
The only reason I knew anything about PEN SHELL PEARLS was by seeing my friend Rachel Fields’ scientific display at the Sanibel Shell Festival this year…about Natural Pearls and being fascinated by her blue ribbon exhibit.
After sending her photos of Gary’s PEN SHELL, Rachel responded by saying…
“That does look like a pearl! It’s called a blister pearl when formation occurs and the growth is still attached to the shell”.
Then she explained “When pearls form often times it happens because some exterior object kind of puts pressure on and crushes the shell inward causing a piece of the shell to fall off into the body of the mollusk and if it happens near the mantle the mollusk will secrete a protective coating around that piece of shell that’s broken off. Sometimes it happens far away from the shell and more internal which causes free-formed pearls and sometimes it happens up against the side of the shell which causes the pearl to form merged to the shell (and is called a blister pearl)”.
Now you can see from Gary’s shell that his PEARL formed against the shell and it still attached…. a BLISTER PEARL. Yep, it’s just like our type of skin blisters although we make just fluid inside our blister instead of a PEARL, right? When I get a blister, I’d much rather go through the pain to get a PEARL instead of crummy fluid. LOL
When a PEN SHELL produces a FREE-FORM PEARL, it can be a gorgeous lustrous PEARL like Rachel showed in her exhibit. The problem with finding pretty PEN PEARLS is that they crack easily after a week or two and if they do make it without cracking, it may take about 4 or 5 years for them to become pearlescent.
But when they don’t crack and become lustrous…. Gorgeous!
Rachel was kind enough to share more information from her Natural Pearl presentation, so I thought it would be easier to publish a page dedicated to her research- CLICK HERE. This will probably answer all of your questions because it answered mine! Like… “What other shells make PEARLS?”.
She shows us QUAHOGS…
QUEEN CONCHS produce PEARLS as well- They are pink! Captain Brian let me borrow his book Pink Pearl: A Natural Treasure of the Caribbean
This one should really get your goat… a LION’S PAW. Oh my! Just to find a LION’S PAW is special… but to find a LION’S PAW PEARL? That would send me two clouds above nine!
Thank you Gary, Mary, Cameron and Lauren for coming on the iLoveShelling cruise with me and asking me about your PEN SHELL PEARL and also to Rachel (NYC) for sharing so much invaluable information with all of us about Natural Pearls. This is another example about why i Love Shelling, Shellers and the Shelling Community! It’s so edshellcational!

Never Desperate Beachcombers
Posted by: | Comments
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.

Maiden Voyage Sight Sea-R Shelling Cruise Was Incredishell
Posted by: | Comments
Our first iLoveShelling Sight Sea-R Cruise was even better than I could ever even imagined! This brand new Sight Sea-R boat proved to be the absolutely perfect shelling excursion with plenty of room to take our 48 amazing shellers to this new shelling destination only accessible by boat… Big Hickory Island.
Not only is the island filled with our favorite treasures (shells, of course)….
We kicked this shelling adventure off with lots of other goodies too. Giveaways! Clark and I brought a big bucket of Sanibel Six shells so everybody could pick out a lucky shell to get things started. Then we treated everybody to iLoveShelling waterproof Seashell Identification guides, bumper stickers and had raffle prizes for hats and tee shirts. So. Much. Fun.
Our biggest surprise was from Mary and Jana of Sealife By Congress- my fave jewelry store. You won’t believe it, they gave every single person on this cruise a sterling silver sealife charm. Seriously. They came on the boat with large baskets filled with beautiful pieces of jewelry and let us all pick our gift of hand made sterling silver dolphin, starfish, sand dollars, scallops and yes… even junonia charms. So sweet!
Texas cutie cousins Pat, Pam, Kay, Peggy, Debby and Linda were thrilled to all receive such a gracious gift of jewelry. Thank you Sealife By Congress!
Let me tell you… this boat turned into a parrrr-taayyy!
So to top it off, on the boat ride to the island we spotted lots of different wildlife. There were dozens of species of birds but we were most excited about seeing many ROSEATE SPOONBILLS…
We also saw a rare sighting of a SEA TURTLE popping out of the water and we also witnessed countless pods of BOTTLENOSE DOLPHIN.
This was already so much fun and we hadn’t even starting shelling yet. But I was soooo ready… especially since I saw Holly had made a special shell bucket for herself with “My Shell Holl” on it- heehee. She also made one for her husband Ted that said “Collect-Ted Shells” and she made one for me with “My Pamtastic Shells”. OMG So stinkin cute.
We were all ready to hit the beach to find shells. And we did! Sandy from Fort Myers Beach’s newspaper The Island Sand Paper found some awesome shells to make her smile. Go back and take a look at the second photo from the top, those are her shells- See? Awesome.
We couldn’t believe how many WORM SHELLS we all found…
And lots of SHARK’S EYES…
During the boat ride back, I asked how many people found CONE shells (and not ones they picked from the “lucky bucket”) and 19 shellers raised their hands. Wow!
I’m always so happy to meet families that shell together. Christine, Anthony, Paula, Bryce and Dominic (from VT and MA) were such a pleasure to talk to.
I asked Bryce what his favorite thing about the cruise was and he reminded me that together we saved a SEA HARE that got washed up on the beach. We put the SEA HARE back in the water and after a minute, he revived and swam away- that was his favorite moment. I asked Anthony what his favorites were and he immediately showed me his ROSE PETAL TELLINS (with 2 COCQUINAS as well).
Brooke and Josh from Georgia had favorites too… SAND DOLLARS.
Clark and I loved hearing Keri (also from the Sand Paper) tell about shelling bringing back so many memories of her childhood while shelling with her grandmother. I think that’s why we love it so much… we explore the beach like we are kids again and remember those days.
Thank you Captain Phil and Meg for such a great adventure!
I still can’t believe how exciting every moment was with perfect weather seeing DOLPHINS, ROSEATE SPOONBILLS, OSPREY, PELICANS, a SEA TURLE, lots of seashells and the best group of people Clark and I could wish for.
To make a fairy tale ending, on our way back to the dock we watched the sun set over the Sanibel Lighthouse…
It was a very special day to remember. Oh but wait… I still have more photos and I have just a few more things I want to share with you about this day on my next post. The surprises continue!
Thank you Sight Sea-R Cruises!
