"This volume is aimed at providing a broad view of crustacean lifestyles, and, from this vantage point, increasing our understanding of the significance of features of crustacean morphology. Crustaceans are probably the most diverse of all groups, whether insects are included or not. As a result, it would seem that crustaceans should make ideal target organisms for studies of evolutionary development, physiology, or evolutionary ecology and not just phylogeny, as has often been the case in the past. The chapters included here summarize the main ecological details of crustacean lifestyles in all habitat types that crustaceans occupy. In that sense, it is also a modern natural history book, and we hope the stories included will be of interest to crustacean biologists who would like to know more about the animals they study, especially if that study occurs primarily in the laboratory"--Preface.
