"The Book of Shells" by M. G. Harasewych and Fabio Moretzsohn

How many different kinds of seashells are there? No one can say for sure. Tens of thousands of mollusks are known to science, and there are certainly far, far more out there waiting to be discovered.

"The Book of Shells" by M. G. Harasewych and Fabio Moretzsohn covers a wide range of shells, a shell being the external skeleton of the creature that lives within it. Each shell, whether brightly striped or bland and pale, shines in its own way. Begin the slide show for examples of shells described in the book.
