The lifesize guide to identifying and classifying shells. Over 100,000 kinds of mollusk have been recorded and some estimates of yet to be discovered species exceed a million. They have colonized nearly every habitat on the planet, ranging from high mountains to the depths of ocean trenches, and from the poles to the tropics. They range in size from that of a grain of sand to a meter in length and many hundreds of kilograms in weight. The Book of Shells curates a lifesize collection of 600 of the most significant examples, presented by one of the world's preeminent scholars. Each shell is reproduced lifesize, and the book is arranged by shell family, and by size within each family, providing instant visual identification and comparison. Accompanying text for every example is divided into charted specifications, a general "biography," a summary of related species, and an extended caption that provides a detailed visual description. Magnified details reveal the diversity of pattern, while miniature line drawings reveal the variation in structure. The result is a collector's piece that is both a significant resource for enthusiasts and scholars, and the most visually stimulating guide to shells you could wish to find.
The nature of the marine shell fauna of the Caribbean is extremely diverse, seeking shelter beneath the sand of beaches, under the rocks of coastal areas, in the soft deep mud of estuaries, in dark submarine caves, in the thick growths of marine prairies, and under branches of vast coral outcrops. It remains unobtrusive and often difficult to discover. Each species has its geographical distribution and populations vary in size, shape and colour according to environment; some animals migrate seasonally far afield. Tidal movement in the Caribbean is unspectacular other than during the spring and autumn equinoxes when shallow reefs and sand flats emerge briefly. The intertidal zone remains stable and undisturbed, with the exception of the passage of tropical storms and hurricanes, governing the lives of many gastropods and bi-valves.
The first field guide to the seashells of India, this book describes more than 300 common species, providing precise descriptions of shell morphology, habits and the habitat of each species. It includes 13 full color plates, bibliography, glossary and index of scientific names and will interest both amateur collectors and beginners in conchology.
They have done time as jewelry and tools, as medicines, currency, and symbols of industry--and they have intrigued people, from beach-combing toddlers to serious scientists, since time began. Native interest meets natural history in this exquisitely illustrated account of the science and culture of seashells. With closeup photography and basic explanations of different shell types--univalves, bivalves, and cephalopods--how they are formed, what mollusks inhabit them, their morphology and life cycles, and much more, this is the book for anyone with an interest in seashells. This book includes information on the bewildering array of shell shapes, colors, sizes, and types, and describes where the different shells can be found throughout the world. As informative as it is visually arresting, the book will appeal to amateur and expert, collector and casual beachcomber.
