Book Description
This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.

Book Description
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.

Book Description
The snails found living on rocky sea shores are among the most rewarding invertebrate animals to study. Species such as dog-whelks, topshells and winkles are easy to find, capture, identify, measure and mark. This book provides a key to common species, background ecology, an overview of rocky shore habitats and the techniques required for anyone to study this fascinating and accessible fauna.

Book Description
The Mollusca, Volume 7: Reproduction presents the significant features of reproduction for one of the significant major molluscan groups. This book reviews the reproductive biology of land snails, which offers the basis for making fascinating comparisons with other terrestrial groups in illustrating how evolutionary various groups solved their common problem of laying eggs. Organized into six chapters, this volume begins with an overview of the reproductive biology of prosobrach gastropods. This text then provides a comparative morphology of land snail reproductive anatomy. Other chapters consider the endocrine control of the female reproductive activity of Lymnaea stagnalis. This book discusses as well the transition in intraspecific and interspecific sexuality. The final chapter deals with cephalopod reproductive biology. This book is a valuable resource for readers who are in need of more appropriate animal systems for solving research problems pertaining to general reproduction, cytology, sex determination, biochemistry, gamete biology, neuroendocrinology, and evolutionary biology.
