About the Little Pear Whelk Seashell

Photos and info about the Pear whelk, or Fig whelk, seashell which I find regularly when out on the boat.

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.

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

Found a beautiful knobbed whelk with a hermit crab inside, but got some photos.

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.

Real Live Lightning Whelk Mollusk

A living lightning whelk with a pretty shell gave me some nice photos to take home.

The lightning whelk seashell is one of my favorites, with it’s stripes and long shell opening. It can grow to quite a big shell also. I have seen many of these shells, and have some in my collection, but this is the first time I have found a live mollusk inside a lightning whelk shell.

I have a little video below where you can see it moving along the sand.

This shell had a particularly white spire – top swirl – which was quite unqiue. Instead of finding a hermit crab dangling his legs out of the opening, I saw the snail! Honestly, I didn’t expect that when I saw the shell moving around on the soft sand of the river bottom. Once the snail dies, I’m betting a hermit will move in. I may come across this shell again on my adventures.
