Delicate jellyfish and anemones, octopus, tentacled squid, and bizarre-looking soft-bodied sea creatures were meticulously recreated in glass by father and son artists Leopold and Rudolf Blaschka in the late nineteenth century. Renowned for their beauty and exacting detail, the Blaschka invertebrate models were commissioned by universities and museums throughout the world as teaching models for students of natural science and marine life. Illustrated here for the first time with breathtaking new photography are 60 of the most exquisite models from the exceptional collection of Harvard University's Museum of Comparative Zoology. Together with Harvard’s famous Glass Flowers, a new exhibit of these restored glass animals now comprises the largest Blaschka collection on display in the world. Bursting with intricate details and stunning photography, this elegantly designed book will be a must for all those interested in marine biology, the delicate art of glass craftsmanship, the history of science, and the quiet beauty of the natural world.
