This book is intended to help biologists, commercial shellers, amateur naturalists, teachers, and students identify freshwater mussels found in the streams and lakes of the Midwest. It includes 78 species, over half of which are rare, threatened, endangered, or extinct. The species are arranged in groups that approximate their systematic relationships; therefore, similar-looking species will often, but not always, be grouped together. An index to both the scientific and common names is given in the back of the book.
