900 mm!  I'd like to see that one. All of your posts of specimens in this thread are impressive! I don't have anything in Busycon over 11".

Astounding! A contender for largest gastropod specimen (not species on average) in the world, no doubt.

This past Saturday afternoon, while shelling intertidally around the St. Augustine, Florida Inlet area on the minus tide, I was amazed to come across a day late Christmas gift and prize for the collection: a huge and alive Busycon contrarium (Conrad, 1840), mostly buried in the sandy mud at the entrance to Comanche Cove Marina, next to the Vilano Beach Bridge.

Prior to this one, the largest I had in my collection was about 225 mm (9 inches). I understand they can reach up to 400 mm!
