Mangroves Are Homes to The Shell-makers and Shell Thieves

The shell-makers are the mollusks, or sea snails, which begin life as tiny creatures who will make stunning and intricate homes we call shells. The shell thieves are the hermit crabs who take over the shells once the mollusk has died and left it empty. Let’s be clear, they have to steal these shells to survive, and they don’t kill the owner, just move in once it’s no longer occupied.

Of all the shells I find on my Florida boating and beach-combing journeys, 99% of the gastropods (shells in one piece, not two) are filled with one of these; mollusks / sea snails, or hermit crabs. Rarely do I find a pretty spiral shell which is empty.

Let’s Take a Boat Ride and Find Some Wild Florida Things

Once we launch our flats boat, we head out across the main channel of the Intracoastal Waterway (Indian River where I live) and enter the back channel. The waterway we travel is not as deep, but it is large with numerous islands and shallow canals. It would be very easy to become lost, or turned around in this area. My son has been fishing here for many years so he knows where to go and how to follow the deeper water while running the boat. The water is murky as you can see in my photos, and it is saltwater. On this day in May the water temperature was around 85 degrees. Very warm! We saw many dolphin, but no manatee.

We pull up at a canal which is emptying into the larger canal as the tide is being pulled out (photo below). Tides are weird way back here because the water has a long way to go to meet the ocean up at Ponce Inlet. The water can move fast in places depending on what the tides are doing.

In the photo below the water is rushing toward me. The tide is going out. The greenery you see are mangroves. The bottom is sandy and the water is shallow – about to my knees. (There is an excellent article about Florida mangroves at the FDEP (Florida Department of Environmental Protection.)

To the right of the photo above I see grass and a sandy bottom just below the water. Soon the sand will dry out while the tide is low. This is where life abounds.

The shell-makers and shell thieves live in the same places as far as I can tell, and they love the mangroves. The conchs and whelks can probably find food in this ecosystem and the hermits can find empty shells. There were no birds here, but we usually do see herons or other birds (sometimes the Roseate Spoonbill) along the edge of the mangroves.

We beach the boat in shallow water here and I get out to find sea life to photograph. I expect to find lots of hermit crabs and I do. One is poised at the top of a stalk (below). Others inhabit whelks and conchs (lots of crown conchs) and they all scurry around doing their thing. Sometimes I find groups of hermits together and I don’t know what they are doing except maybe inspecting each other’s shell size. I’m not a scientist, but I know they need to upgrade to bigger shells as they grow.

As I begin my walk I immediately see three different shells at my feet. A pear whelk (bottom of photo), big tulip, and crown conch are all scurrying. The sea snails move slowly, but the hermit crabs, which now live in the shells, are quick. I can see their spidery legs pulling the shells along the sand.

Those two shells at the top, in my photo above, meet up and the bigger one seems to be bullying the smaller and pulling at the shell. I plan to do some research on our local hermit crab population and write a post all about it. I most often see the Striped hermit, like the one in my photo. One time I found a Giant red hermit crab and that was awesome! Right now, I don’t know much about the activity of hermit crabs but I often find clumps of them together.

I’m always amazed at the various sizes of hermits I find in the wild. The one inside this little shell is very small. I wanted a photo of the shell to maybe identify it, but I don’t know yet what it is.

Below is a photo of a haven for sea life. In this murky water, which is at the base of the mangrove tree roots, are oysters, small fish, hermit crabs and quite possibly live sea snails.

A little further along and I found higher ground where the red mangrove roots could be seen. At high tide the roots are mostly covered by water. See the oysters attached along the base of the red roots? Oysters are important for filtering the water. We have to be careful not to hit any oyster beds with our boat, and it’s one of the reasons I wear water shoes. Oysters can easily cut feet!

As I walked along, blue crabs scurried out of my way, or ducked into holes in the sand to hide.

I saw small fish, but larger fish use these mangrove areas to have their young and find food. Fiddler crabs were abundant on this island and another island we visited which was closer to the Inlet up north.

All those little brown things are tiny Fiddler crabs scurrying into the shadows as I walk by! There had to have been millions on this island…! Fiddler crabs are a favorite food of Sheepshead fish. Other fish probably eat them too.

The Best Part of Florida

In my opinion the best part of Florida is where there are few to no people. The mangroves and backwaters, during the weekdays, are peaceful and quiet. It’s like going back in time to the way Florida was before the invasion of people. I imagine this is how it looked to the Indians and explorers. But I think the wildlife was much more abundant when they were here.

Then I catch a glimpse of the high-rise condos along the Eastern horizon and it’s back to reality. I fear for this area because my biggest problem with Florida is it’s seeming lack of consideration for natural habitats. I can’t help but wonder if years from now no one will get to see what I’ve seen today.

Why Are You Interested In Seashells?

When I began writing this blog about seashells I did so hoping to sell paper products containing my seashell photography, like the card below. I lived in New Hampshire at the time, which is funny because my shells had been collected when I lived in Florida. But my Zazzle business, and especially my seashell and beach-related store, needed promoting and I figured a blog was the way to go. What I discovered right away was that my blog was turning into something else.

In the beginning I wanted to promote my store.

The blog quickly became a learning experience.

People reading my blog wanted information about seashells. At the time I knew very little about the shells I had randomly collected while living in Florida. Now, it was time to learn. For some reason I had never thought much about how those empty shells got there or where they came from. The mollusks, or sea snails, which made them were amazing creatures. I wanted to share what I learned with others who wanted to know.

A move back south made writing easier.

The first years of writing were spent in the North, far from tropical beaches, but now that I am once again in Florida, writing has become easier. It’s always better when you have access to the subject. With the purchase of our boat, I have even better access to remote spots where I may come across fun nature photos to share. And I have my camera with me in the form of the iPhone now too.

Discovering local species is most exciting.

Starfish and sand dollars were my first focus because it was easy to find information about them, and I knew what they were called! It’s been a journey, and I’ve made mistakes along the way, but my writing has improved and so has my knowledge of marine snails and the homes they carry on their backs.

Getting out in the Florida wilderness.

Now I would say that I am interested in shells because their lives fascinate me. Sizes, shapes and colors of seashells vary because of the snail which made them. I am lucky enough to get to see those living creatures now and then and share photos here on my blog. Usually I have far too many photos to deal with and not enough time to write, but it’s fun. I hope my readers can learn something which makes them appreciate the beauty of shells.

Fun Times In Florida 2018 and Happy New Year

What have I done over the past year? As we say hello to a new year, I’m viewing photos to remind myself. In Spring we visited St. Augustine when my son’s girlfriend came to visit.

My two sons and I went down to Merritt Island to watch the SpaceX rocket launch.

We ate at our favorite local restaurants that have water views.

We went boating, fishing, and swimming along the ICW / Indian River, with a stop off at Disappearing Island to float a bit.

And of course I collected bunches of shells and took many photos of my favorite islands.

I took a few trips to Smyrna Dunes Park to get exercise and search the beaches for new seashells.
