Archive for Ponderous Ark
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!
I spied thousands of ARKS at Gulfside City Park on Sanibel Island this morning. Most days you can find TRANSVERSE ARKS scattered along the beach since they are one of the most common shells on Sanibel.
There are a few different species of ARKS so let me show you the difference. Top row left to right- a MOSSY ARK and a TURKEY WING. Bottom row left to right- CUT-RIBBED ARK, TRANSVERSE ARK and a PONDEROUS ARK.
It’s a little easier to identify bivalves and see the difference (and the likeness) between them by looking at the interior of the shell.
I only had a few minutes to walk the beach today so I just wanted to look for minis in some of the wrack lines I pointed out the other day in my Shelling 101 video. I found TUSK SHELLS (there were thousands of those too), a KEYHOLE LIMPET, WENTLETRAPS, CERITHS, AUGERS, a TURRID, juvie CONCHS, juvie OLIVE, and a piece of CORAL.
I also found a somewhat beat up LINEATE DOVE SNAIL.
If you need any help identifying any of these shells, check out my Seashells Identification Page…
As I walked this morning, I couldn’t help but notice this amazing village sand sculpture on the beach- with its own arena and swimming pool. I was inspired to write about ARK SHELLS because so many artists like to use these sweet little white shells as embellishments for their pieces of art- just like this beach artist did. ARKS are perfect decorations for so many projects. Inspiring!
If you have a second, stop by and check out my online Art Gallery…
After several weeks of east winds, the west winds have finally arrived to drive some shells on to our beaches. Today was only the first day of the westies but since it was a really low tide this morning, I figured I’d find some goodies. It’s always a good day when you find an ALPHABET CONE and you’ve got to see just how darn cute this little juvie HORSE CONCH is…
I couldn’t believe I found this ANGEL WING sitting in the high wrack line…
I love when I find shells like this BANDED TULIP lying on the beach like this.
Tonya, Beth and Max from Ohio had their bags filled with all sorts of treasures.
Wanna look in their shell bags? I sure wanted to too! COCKLES and CONCHS and CLAMS…
Max found this live LIGHTNING WHELK in the high tide wrack line so he walked it down to the water and gently put it in the water. Good for you Max! You helped save this beauty.
I found local Sanibel sheller Lynn walking her very happy standard poodle Alexander with a pocket full of seashell treasure too.
Look at those pretty those COLORFUL MOON shells along with those candies and a mini TURE TULIP.
There was all sorts of bivalves scattered along the beach. I found this ATLANTIC COCKLE, PONDEROUS ARK and SOUTHERN QUAHOG together on the beach just like this…
This is the biggest DARK CERITH I’ve ever found. It’s one and a half inches long!
I was pretty pleased with what we all were finding on the beach near Donax Street today after the first day of west winds. Tomorrow might be even better!
