If you see a snow-white angel wing or hold a cockle shell or examine a periwinkle, you will be fascinated with the beauty of sea shells and awed by the spectacular handiwork of nature. Yet these three shells are no more remarkable than thousands of others known to man. The How and Why Wonder Book of Sea Shells describes the major groups of shell animals and tells about their habits. You will discover that there is an endless variety of shells. Some are small and delicate and beautifully colored. Some are huge and rough. Yet the shape, size and structure of each shell animal enables it to live its own particular style of life.

Do you know what the Juno's volute and the precious wentletrap look like? These are rare shells and they are a collector's dreams. But more common shells are fun to collect, too, except perhaps some huge ones that are almost too heavy to lift. One must be able to observe carefully to classify carefully. Ability to observe is important to scientists. Studying the characteristics of shells to organize them into collections will help young people develop this ability.
