Marine biogeography, the study of the spatial distribution of organisms in the world’s oceans, is one of the most fascinating branches of oceanography. This book continues the pioneering research into the distributions of molluscan faunas, first studied by biologists over 160 years ago. It illustrates 1778 species of gastropods in full color, many of which are extremely rare and poorly known endemic species that are illustrated for the first time outside of their original descriptions. The spatial arrangements of malacofaunas shown in this book can be considered proxies for worldwide oceanic conditions and used as tools for determining patterns of global climate change. The book's documentation of evolutionary "hot spots" and geographically restricted endemic faunas can also be used as a base line for future studies on patterns of environmental deterioration and extinction in the marine biosphere. Documenting the evolution of the amazingly rich worldwide gastropod fauna, this book will appeal to physical and chemical oceanographers, systematic and evolutionary biologists, historical geologists, paleontologists, climatologists, geomorphologists, and physical geographers. The authors incorporate aspects of all of these disciplines into a new classification system for the nomenclature of biogeographical spatial units found in tropical, subtropical, and warm temperate seas.

Bivalves are one of the most important groups of marine animals: they are abundant in benthic communities, they are sought after as seafood or ornament, and their shells are almost always conspicuous on the world's beaches. This identification guide for West African marine bivalves covers 462 species belonging to 59 families, based on an extensive material collected over several decades from Mauritania (Cap Blanc) to Angola (Baia dos Tigres), and now housed in in the French National Museum of Natural History. Therefore, any bivalve collected in the marine near-shore habitats of West Africa is most likely to be covered. Deep sea species (those normally collected below 500 meters depth, an additional 150 species) are listed but not treated at length. Profusely illustrated with over 3500 color and 1600 greyscale photographs, 800 stippled drawings, and an average of twelve views per species, the book is intended to be both the definitive resource and accessible to the non-specialist. Each species receives a description accompanied by a drawing of the interior showing the diagnostic details of the hinge and internal impressions and a photographic plate showing a selection of specimens from different localities across the species' range, an indication of distribution accompanied by a schematic map, an indication of habitat, and remarks, including comparisons with similar species. In the headings for each family, generic descriptions are illustrated with thumbnails of the included species to provide visual orientation. Morphological terms used in descriptions are explained in a glossary. Preceding these extensive taxonomic sections of the book is an introduction addressing the history of research, the physiography and hydrology of West African coasts, and the general characteristics of bivalves.

Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.
