This isn't a large museum, but it is well done. Those who like shelling (after all, if you're on Sanibel you'd better) will think this is a neat place. If you're not into shelling, you probably won't like it. The museum has shells from all over the world, and a lot about the ones you are likely to find on the shores of the island. Good information about the life of the little critters that live in them, how to clean and preserve them, and the history of how shells have been used in the past. Overall, for my family, a great place to spend a hot afternoon.
