I don’t live on Sanibel Island and I haven’t even visited the Island in Florida for almost 20 years, but fortunately I know of a great blogger who lives there and shares her shelling knowledge with the world.

Recently she posted some photos of four small, similar-looking seashells that she had collected from the beach and without a keen eye, you may think they were all the same.

Pam does a nice job of pointing out the differences between the Mauve-mouth drill, Pitted Murex, Ribbed Cantharus, and the Gulf Oyster Drill.  Go see!
