The left handed lightning welk from Florida is, as far as I know, the only common left handed mollusk or sea shell. A right handed specimen of this shell is extremely rare. Here is your chance to own a matching pair, a very rare right handed and a matching left handed.
Please see the pictures with this listing. Those are the two shells you will receive. As you look at the first picture you will see that the opening is on the left which the opening on the rare specimen on the right side of the picture is on the right side of the shell.
These shell are from my personal collection. I collected these specimens about 1970. They are from Florida..
I have tried my best to correctly identify the shells I am selling, but it is possible that I have made mistakes. It is sometimes difficult because of a range of color and/or shape within a species. As an example, an article in the April 1964 and September 1964 issues of Hawaiian Shell News describes how Voluta Damoni gradually changes along it 3000 mile coastal range from almost no color pattern to a very colorful pattern. Several species have sub species with a lot of variation. The sizes I list are approximate. The shells you will receive are the shells in the photos with this listing.This set of shells can be shipped to most countries. International shipping is exclusively offered through International Shipping Program (ISP).Thanks for shelling with me.
