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.  The other types are the Netted Olive (Oliva reticularis) and the Variable Dwarf Olive (Olivella utica).  The Netted olive is found in the southeastern part of Florida only.

My shells 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.

Lettered Olives – typical of what I find

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.)

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.

  1. Nothing as fun as looking for shells along the beach! We like to hunt for the fossilized sharks teeth too.

      And do you find many sharks teeth where you search?

      1. They are only found in certain areas…no idea why. But yes we would find a handful each time we went. You have to make your eyes accustomed to the teeth color and shape because thy are small and black.

        I know what you mean about searching with certain things in mind. There is so much on some of the beaches it is easy to miss the important finds. Which beaches do you generally frequent?

      3. I think it was Venice. My parents live there and take me. I love walking that beach!

        Venice is one that is known for it’s shark’s teeth. That would be fun. I wasn’t sure if you meant a Florida beach or someplace else. Once day I plan to travel around to some beaches I have not visited. There are a lot to choose from here!

    Very pretty shells. I have a small olive shell (just under 2 inches) that is patterned very much like the one on the bottom left in your Sanibel Island photo. It used to be greener but has faded and the pattern is now brown on white. I have had it since childhood and don’t remember where it came from in Australia (probably Victoria). You have a great collection. I didn’t know that some of these shells could be so large.

      I don’t live near Sanibel of my collection would be quite huge. But it makes collecting more of a search over on the East coast where I am. I love the smooth shape of the olive shell even if the patterns have worn off. Isn’t it nice that we can keep shells for so long and they stay interesting as a reminder of days on the beach. Thank you for leaving a comment!
