Compared to other arthropods, crustaceans are characterized by an unparalleled disparity of body plans. Traditionally, the specialization of arthropod segments and appendages into distinct body regions has served as a convenient basis for higher classification; however, many relationships within the phylum Arthropoda still remain controversial.

Crustaceans, due to the great diversity of their body organization, segmentation patterns, tagmatization, limb types, larval forms, cleavage, and gastrulation modes, are highly desirable for the study of questions at the interface of evolution and development. Modern interest in evolutionary developmental biology (evo-devo) rests on the molecular genetic approach and a variety of molecular techniques have proven fruitful when performed on crustaceans. Evolutionary Developmental Biology of Crustacea presents a comprehensive treatment of all aspects of the field, beginning with a discussion of the implications of the typological Bauplan and phylum concepts versus historical concepts such as ground pattern and monophylum for the formulation of conceptual questions in evo-devo. Following this, the authors present the results of Hox gene expression in various crustacean taxa, aspects of segment formation at the cellular and genetic levels, the formation of segmental structures such as neurons, ganglia, and limbs, and the role of morphological ontogenetic characters in resolving phylogenetic relationships. By covering so many general aspects of crustacean development, morphology, and evolution, Evolutionary Developmental Biology of Crustacea serves as an indispensable reference for developmental and evolutionary biologists investigating the role of genetics in evolution and development.

"As a young and impetuous gradate student, I thought that sorting out the phylogeny of crustaceans would simply take but a little time and concerted effort to eventually reveal the truth. Everyone could then agree and further research would proceed apace. How naïve I was. First of all, I had never heard of Kurt Gödel's incompleteness theorems and hence the impossibility of achieving such an end. But even so, what progress we might have made turned out to take longer than anyone could have imagined, and the effort would be immense involving many people and a number of laboratories-and that task still continues. What no one could foresee in the 1960s was that the focus of everyone's attentions would completely transform. Traditional pure anatomy would be augmented with more sophisticated developmental genetic work. Concurrent with that effort molecular sequencing would become a remarkably effective tool. And with these new sources of data, the concept of "crustaceans" would yield to a new construct-Pancrustacea-within which the arthropods that we referred to by the name of "Crustacea" became a series of monophyletic smaller groups that mark a paraphyletic transition from a mandibulate ancestor all the way up to a crown group that few in the 1960s expected-Hexapoda emerged within the pancrustaceans"--

This is the seventh volume of a ten-volume series on The Natural History of the Crustacea. Chapters in this volume synthesize our current understanding of early crustacean development from the egg through the embryonic and larval phase. The first part of this book focuses on the elemental aspects of crustacean embryonic development. The second part of the book provides an account of the larval phase of crustaceans and describes processes that influence the development from hatching to an adult-like juvenile. The third and final part of the book explores ecological interactions during the planktonic phase and how crustacean larvae manage to find food, navigate the dynamic water column, and avoid predators in a medium that offers few refuges.

Crustaceans are distinguished from myriapods and insects by many more traits. A striking difference is seen in leg structure. The morphological characteristics Taxonomy, Anatomy and Physiology of various crustaceans including vital systems are the major part of this book. Varieties of Crustaceans have its economic values in captures and culture practices so their basic nature, structures functioning details are needed. Those lines are touched in this book. Contents: Introduction Crustacea, Taxonomy of Crustacea, Body Plan and Appendages, Digestive System, Excretion and Osmoregulation, Musculature, Respiratory System, Circulatory System, Nervous System, Sense Organs, Endocrine Gland and Hormones, Reproductive System, Economic Importance, Few Crustaceans.

Gregory Edgecombe has assembled premier specialists in the study of arthropods, each of whom addresses a major issue in arthropod diversity by reviewing evidence of key fossils from a common perspective and examining the interplay between extinct and extant species through inference of the structure of the arthropod evolutionary tree.With the most complete collection of modern perspectives on the history of Arthropoda, this volume advances the current debate on paleontology's role in discovering life's hierarchy. Of interest to specialists in a wide range of fields including paleontology, petroleum geology, oceanography, and entomology, Arthropod Fossils and Phylogeny will be the standard general reference on arthropod paleontology for years to come.
