Both Busycon carica & B. caniculata are very common in Delaware, Maryland, and the Eastern Shore of Virginia (especially behind the barrier islands). Just north of Norfolk on the "Delmarva Peninsula", there still is a company that harvests these mollusks, cooks the meat, and exports it for consumption. Normal size of the shells is 6-10", with some much larger. There is also a sinistral relative of B. carica, which is different in shape, although quite similar, to B. contarium. It is not very common, but I have collected over 50 of these in the past five years. If you decide to venture this far north, let me know. I will give you some more specific directions.
