About the Little Pear Whelk Seashell

Pear whelks (Busycotypus spiratus) are cute little seashells and they can be colorful. They resemble the lightning whelk, before it grows big. But the Pear whelk has it’s opening on the right side, like most gastropods.  This one is also called a Fig whelk and it’s max length is 5.5 inches.  In Florida it is common along any shoreline.

In this first photo you can see the operculum (trap door) which is a hard piece that closes the mollusk up inside it’s home.  The snail is beginning to come out of the shell because I picked it up from the shelly bottom where he had been resting quietly.

I expected to see a hermit crab inside, and was delighted to see the creature who made the shell instead.  This water is very shallow as you can probably tell, so he was living close to shore.  I snapped this shot and put him back down without bothering him further.

Above: Found this pear whelk while walking along a deserted beach in the backwater area of the ICW (Intracoastal Waterway). I’m guessing they prefer the calmer waters near the islands and that is why I never find them along the ocean beach.

In the photo below you can see how shells can look in the wild. They are not all that pretty when covered in mud and slime. I knew the type by the shape of the shell.  Yup, hermit crab inside.

I’ve never collected one of these shells because every one I’ve encountered (except for the live one in my first photo on this page) has been inhabited by a hermit crab! The shells are small and easy to carry on the back of the crab.

Pretty yellow shell

I just loved the pretty yellow color of this Pear. It stood out among the muddy bottom. It was moving along on the back of it’s new owner. Can you guess? Haha!

Below you can see the crab peeking out.  This is what I often encounter.  I think there are more hermit crabs in my area than there are seashells!

Small shells like these are not the only place you will find hermit crabs. I recently pulled up a beautiful big knobbed whelk with such an owner.

About the Knobbed Whelk Seashell and Mollusk

When we go out boating in the backwaters along the Intracoastal Waterway in my area I love to stop at islands do some beach-combing.  It’s been cold here in Florida (okay, you don’t feel bad for me, I get it) but finally we had a sunny day in the 70’s, so we went out on the boat.

Among the larger seashells I have found while checking out the wrack lines (up where the tide deposits stuff) is the knobbed whelk (Busycon carica). Usually they are partial shells, or nearly unrecognizable from wear and tear.

The one featured on this page was found just off-shore along a camping island which was deserted the day I was there.  I’ve never found one this whole and beautiful.  It was exciting to see.

The water that day was clear, and cold for Florida at 62 degrees. It was January but in the 70’s and sunny. I was wading in the shallow water along the beach when my son spotted this knobbed whelk under the water. This shell was sitting at the edge of that black area of water you see in the photo.

About Olive Shells You May Find in Florida

Olive shells are easy to identify. They are long and smooth measuring from tiny to 2.7 inches in length.  The shell on the right in my photo below is nearly as large as they get.  Their spire (top swirl) is small and the opening (aperture) is a slit all along the side of the shell.

The Lettered Olive (Olive sayana) is the one I am showing in my photographs on this page. It is the largest of the olives. Mine were collected (empty – nothing living inside) from Florida beaches.  Most of my olives are dull, worn and broken, but pretty ones can be collected from the Gulf beaches where the lack of waves tends to preserve the beauty of seashells (see my last photo on this page).

Other Types of Olive Shell

The Netted Olive (Olive reticularis) is smaller and is named for it’s net-like markings.  It is more often found in the Caribbean or southeastern area of Florida.  See a photo here at the Marine Species Identification site.

There is also a small seashell called the Variable dwarf olive (Olivella mutica) which is less than an inch in length.  To my knowledge I have never seen one.  But you can see it on the Conchology Inc. page.

The Shells I Have Found

Where I live, on Florida’s east central coast, I rarely see the olive shell.  The one below was found just above the water line at Ponce Inlet.  You can see the mollusk just peeking out in the photo on the right.  The shell was a beautiful dark purple-brown color.

Living shells or recently abandoned ones will have the best color.  Once they are rolled with the waves, continuously scratched by the sand, or washed ashore to sit in the hot sun, their color will fade and the shells can break.

Because finding an olive in any form is fairly rare where I live, I collect all of them, except the ones being used by the owner! Then, I take a photo and let it be.  Broken and old worn shells have their own appeal.

Worn and broken olive shell

Olive shells can be found along southern US coasts including all around the state of Florida.  It is the state shell of South Carolina where this shell is prolific.

Recently I was visiting an island beach while out boating and as I walked the shore I saw these two beauties only a few feet apart.  The tide was low and still going out and there they were.

Yes, they are worn and in less than perfect shape, but finding them made me so happy!  (Also see them next to the tape measure in my first photo on this page.)  That photo was taken after I cleaned them.  (See my post on how to clean seashells.)

Shallow Water Find – Olives and a Crown Conch

These shells don’t appeal to hermit crabs because of their shape – not enough space for the crab.  Because of this, it is one of the few gastropods I can collect without worrying about having a crab tucked down inside.  Those pesky critters can duck inside a shell and hide really well.

The shape of the olive shell most resembles that of a cone shell, but cones are shaped more like their namesake.  The olive is nearly the same width from top to bottom.  The cone shell is something I have never seen on my side of the state.  The best place to collect a cone shell is on the southwest side of Florida, on and near Sanibel Island, which is where I found the pretty Olive Shells in my photo below.

About The Florida Horse Conch Mollusk and Seashell

The horse conch is the Florida state shell. It is one of the largest shells to be found around the coastline and is the largest snail in North America. The horse conch is one of the spindle shells. They are thick and elongated. It looks like someone stretched the shell from both ends. It can grow to be nearly 2 feet in length!

The small horse conchs I’ve come across have all had hermit crabs inside.  As can be seen in my photo, Continue reading About The Florida Horse Conch Mollusk and Seashell

Common Limpet

Found this great nature photography blog by Pete Hillman and he kindly gave me permission to re-blog this post about the limpet. Enjoy, and be sure to visit his site to enjoy his amazing photography. He likes to photograph seashells too!

Patella vulgata

Common Limpet (Patella vulgata)

Have you ever wondered what the underside of a limpet looked like? Note the large muscular foot, the relatively small mouth above, and the tentacles either side.

The Common Limpet has an ashen-grey or greenish-blue shell, sometimes with a yellow tint, and with radiating ridges. It is conical with an almost central apex. The shell is often covered in barnacles. The sole of the foot is yellowish or orange-brownish with a green tinge. Shell length 6cm. They are fairly long-lived, up to 15 years.

Common Limpet (Patella vulgata)

It inhabits the intertidal zone, clinging tightly to rocks along the shore or in rock pools, and with its thick shell it is able to withstand the pounding ocean waves, exposure to drying out, and attacks from birds or fish. It grazes on algae growing on the rocks beneath the water. It is not ‘stuck’ in one position as it may always appear to…
