Up for auction is a very nice, really pretty florida Horse Conch, Pleuroploca (Triplofusus) gigantea, from Captiva Island. My measurement is approx 292mm, right at 11.5 inches. This is a pretty shell -- and in very nice condition. I'm really happy with how well it cleaned up -- It has wonderful color and is in great condition, lacking most of the harsh growth lines that are often present. nice chocolate specimen with lots and lots of nice spiral lines. This shell was... dead-collected but the animal was intact, and I was able to luckily recover the operculum. Accurate and full data accompanies specimens. All shells are guaranteed and returns within 14 days are accepted for any reason. Shipping is free within the contiguous US (via USPS First Class Mailing) and 15.00 USD for overseas buyers (via USPS First-Class/Priority Interntional). For overseas buyers, I will combine shipping. Please let me know your questions via email or at 843-324-5212 Thanks! Mark
