Oh wow, thanks for the great source!
I live 6 miles from the florida border, so, it definitely does cover me haha
I think it might be a Mesa Rams-Horn, or possibly [FONT=Arial, Helvetica, sans-serif]Viviparus Montdort, but I can find no pictures of these snails... other than from what is in the guide.
More than likely its the Rams-Horn. Thanks again for this amazing resource![/FONT][FONT=Arial, Helvetica, sans-serif][/FONT]
