As a child growing up shelling my mother called these shells cat's eyes. To me they will always be cat's eyes but the correct name is shark eye.
I found these shells on a beach along the Atlantic Ocean in central east Florida The coloration runs from browns, to gray, and cream. When I found them they had a chalky white covering (limestone?) so I washed, soaked, and eventually varnished them to bring out their color and shine. The bottom edge of some of these shells are rough. They are close to 1 3/4" long to 1/2". Some have boreholes in the lower section of their body whorl. They were a meal for a predatory gastropod!
Since these shells were all found together I felt it only right to sell them as a set. In the last picture you can see a comparison of the largest and smallest shell. I like whimsy so I have added a photograph of the shells pretending to be eyes, and of course these shells are ideal for shell art, mosaics, beach mobiles, decorations, jewelry, and collections.
I have these in different sizes and many fragments of the shell which are beautiful and fascinating to look at as you can see their internal structure. Contact me if you need a different listing.
If you want a shell that I do not have listed let me know and I may have it!
