Fighting conch shell with mollusk inside

The Beautiful Florida Fighting Conch

This type of mollusk likes calm, shallow water with a sandy bottom.

One of my favorite shells to see up close is the Fighting Conch, or the Florida Fighting Conch (Strombus alatus) as it’s known.  It is in the family Strombidae.

The Fighting Conch can be found on all Florida shorelines, but they prefer sandy, shallow water where wave action is minimal.   That’s exactly the type of place I discovered this one.

Before I came across this living mollusk, I had collected an empty fighting conch shell while visiting Sanibel Island.    On the Gulf coast, this shell is more common than where I am on the East coast.

So what is a conch shell? (Pronounced “konk”) By definition it is a large, spiral-shaped seashell.  It is big, but thicker and heavier than other gastropods, like the whelks.   The conch is the living creature inside which is sometimes harvested to eat.  Conch is on the menu in many tropical based restaurants, and the meat can be from any large gastropod shell.

I’ve also come across a broken and worn Fighting Conch shell with a hermit crab inside. This happened while exploring another similar type of island.

Recently, I was lucky enough to come across this living Fighting Conch while walking the beach of an island in the Florida Intracoastal Waterway.  I didn’t think to measure it, but I’d estimate it’s length to be around 4 inches, and they don’t get much bigger, according to my seashell reference book.

The Beautiful Fighting Conch – this one is alive.

The chunky, wide-bodied shell, with a more compact spire, is a giveaway as to the name of this one.   It is known to “fight” or jump at other shells that could be a danger to it, hence the “fighting” name.

It also has some beautiful coloring.  From the dark purple with orange edges underneath at the aperture, to the light purple on top (it’s spire), even though this one has some green algae and a few barnacles, it was a lovely sight to behold.  I couldn’t help but wonder how beautiful it would have been all cleaned up.

I saw this shell up on the sand at an island out on the Indian River. I picked it up hoping it was empty so I could take it home, but found a living conch inside.   A fun surprise (at least it wasn’t a hermit crab!)

I took it to the boat to show my son – how often do you find something so awesome?  I got my iPhone to take these pictures, and then left it in the shallow water which is it’s home.

My video of this living conch shell.  Somehow it ended up in Slow-motion (I am not tech savvy), which shows the sea water slowly coming in around the shell.

If you are ever tempted to try “conch” when out to eat at a Florida restaurant, this is the type of thing you are eating. The living shells are collected and the animal is pulled out and killed to bring that meal to you.

The Queen, or Pink, Conch is a threatened species due to over-harvesting. For this same reason I do not buy seashells from gift shops or shell shops. When I am walking the beach, or visiting these islands out on the river, I only collect empty seashells.

Florida Fighting Conch and It’s Coloring Page

I just updated my seashell coloring page with a new, fighting conch picture.

The Strombus alatus is part of the conch family – Strombidae – and is a common find on the west coast of Florida. It inhabits tropical waters only. One of the characteristics of this shell is the thickness.  It feels very sturdy and this thickness helps to protect the animal. They can be 4 inches long and there is also a West Indian Fighting Conch which is smaller.

They are herbivores and feed on algae.

Some of this information was found in National Audubon Society’s Field Guide to Shells and
the Free Information Society has more detailed information about this mollusk along with a photo of a living creature.
