A major new reference on fossil, extant glypheid, and litogastrid lobsters, this book offers detailed descriptions of all 120 species alongside photographs and reproductions of historical illustrations when possible. The authors take into account recently added species, as well as progress in the analysis of their history and evolutionary development that has changed our view of the generic and familial classifications of these animals. With almost six hundred drawings, engravings, and photos, this volume is an essential guide to the many types of lobsters.
