How Are Shells Formed?

Answer

To do this, they add small amounts of calcium and other mineral deposits at the edges of their shells to enlarge them a little at a time. Adding these small amounts creates the beautiful patterns we see. You can find more information here: http://www.scientificamerican.com/article.cfm?id=how-are-seashells-created
