Florida fighting conch eyes snout trunkDESCRIPTION

Strombus alatus, commonly known as the Florida fighting conch, contains a small, jagged spire at the top of the shell and about seven whorls.

The front of the shell is designed with two curved edges; these edges allow the eyestalks to look out from under the shell and become aware of its surroundings, keeping the rest of its body safe. The snout acts as a trunk, reaching out from under the shell to collect food. Here you can see a fighting conch’s soft-body, eyestalks and snout emerging from its shell.

  1. Hi my name is Henry I love watching your videos of sea shelling I collect a lot of shells my self those are a lot of cool shells u got there do u have any for sale ?

  2. I visit Captiva twice a year. Last October there were dozens of Fighting Conchs on the shores, all alive, so left untouched. This April, I collected 34 medium-size Fighting Conch shells along the shoreline of Captiva. I have two questions, and cannot find answers anywhere. Why are they called Florida Fighting Conchs? Is there a reason (other than turbulent surf) for so many shells to turn up in the same location at the same time? (Live in colonies? Breeding?)

  3. I Have learned that you cannot import conches from other countries…I have one however, that was brought over by a ancestor in the late 1800’s, from Ireland? And I wish to identify this snail. It has a different inner structure totally so I want to send the pictures I recently took to find out it’s a Conch, white with fawn Periostracum fawn and by it’s whorls is most likely over a hundred years old. This snail sea-shell is 9.m.
