As Eyewitness: Shell proves, the shell is one evolutionary design that has stood the test of time. From crabs to seashells to tortoises and bird eggs, the shell has evolved into a magnificent example of nature protecting her own. This entertaining and informative video provides a dazzling array of creatures that use shells as a means of survival. It also shows many examples of how shells and shell creatures have inspired the human imagination, whether it be the lobsterlike design of a suit of armor or the influence of the chambered nautilus on the invention of the first submarine. Did you know that gastropod means "belly-foot?" Or that ancient royalty used to wear lace collars spun from the golden filaments of mussel shells? Like most Eyewitness videos, this one is filled with many such interesting facts presented in a way that is both fun to watch and easy to follow. After seeing this video, your family's next beach-combing excursion will take on a whole new importance: that of a greater understanding of the world around us. --Michelle Riggen
