Baby Teeth (Four-tooth Nerite)
4" X 6"
The teeth on these shells make me smile. They resemble that phase where a child only has 6 or 8 teeth with spaces between. This particular specimen has bright magenta markings. It seemed an obvious choice to play off this for the background color.
There are a lot of nerites on rocks on the gulf side of Key West. The often get left out of the water at low tide, but fortunately for them, they have a "door" that they can close to protect themselves. They eat algae, which is a good thing. I'm happy to have them around.
