Whelk Seashells Comparison Photography Postcard

My photography of collected seashells postcard, with option to personalize with a message. Lightning whelks (two on left) and Pear whelks are compared in this photo. The apertures (shell openings) are showing, and it is the big difference between these similar mollusks. One makes its shell with a left-handed opening, and the other has a more common opening on the right side. The shells were collected from Florida waterways and were found empty. Use this interesting postcard to reach out to friends, for business, or any communication. It is also collectable as a photo card.
