I imagine every state may have a "state tree", but not all have a state shell. The Florida Horse Conch is our state shell. This is the largest snail in the Americas and very deserving of special recognition. Horse conchs are predators as are most conchs and whelks. Imagine slow motion life or death chases across the mudflats as the horse conch pursues lightning whelks and crown conchs. It's happening out in the Gulf as I type. As Pablo often says, "I wish I were there right now."
The picture above shows two of my personal specimens that I use as teaching aids at school. The "baby" shows more of the usual dark coloration that you see on a live horse conch. It is also intact, whereas the larger specimen is missing the point. (Are you?) ... heehee.
