Murex are a sturdy shell and I find them mainly on Sanibel Island. Search the beach or the shallow surf waters to find a gem.
Mortons Egg Cockle
These little gems were found on Lover's Key. The ones pictured above range in size from 1/2" to 3/4" in size. These three are the only ones in my collection and I just recently found them in May 2010.
The two big cockle shells are actually the halves of one big shell found on Sanibel Island and is about 3-1/2 inches in size. Cockle shells of various sizes and coloring can also be found on Lover's Key, Caya Costa, Estero Island, and Bonita Beach. Caya Costa is an island only accessible by boat and is located between North Captiva Island and Boca Grande.
I've been in love with having sand between my toes since I was a teenager taking the ferry across the bay to arrive at Presque Isle State Park (aka The Peninsula) in Erie, PA.
