8The Chambered Nautilus is one of the oldest living things on our planet. Since the dawn of civilization its form has inspired artists, designers and architects. Nautilus has survived whatever the world has thrown at it for more than 500 million years, persisting even as dinosaurs and many other life forms vanished. Now, however, some believe it could become extinct within a generation. This book celebrates the long history of Nautilus, its role in human culture and the realities of its life today.
