Book Description
This book has informations about Phylum- Mollusca which has great potential in aquatic resources. To value these shall animals their classification anatomy and physiological aspects of various class/genus are described with important biological systems like digestive, respiratory, circulatory, excretory, sense organs and reproductive etc. The anatomy and physiology of animals pave the way for moluscan farming/value addition. The economic importance chapter can be exploited for scientific molluscan fisheries.

Book Description
Reviews the most important literature on the functional morphology and natural history of molluscs over a period of half a century, from 1925 to the present day, and draws extensively upon authoritative papers published mostly in the English language in a large number of international journals during this period. By these means it is hoped to provide an anthology of what is most interesting in the literature in a number of selected topics. Appendices give some practical assistance for the dissection of selected examples

Book Description
Physiology of Mollusca, Volume II focuses on the physiology of mollusks, as well as feeding, digestion, mechanics of the heart, metabolism, and pigmentation. The selection first offers information on feeding and digestion, including Amphineura, Gastropoda, Bivalvia, anatomy of the gut, movement of food, and digestive diverticula. The text then elaborates on feeding and digestion in cephalopods and heart, circulation, and blood cells. Discussions focus on food and feeding, mechanics of heart and circulation, control of the heart, cardioregulatory substances, and blood cells. The publication considers respiration, molluscan hemoglobin and myoglobin, and molluscan hemocyanins. The text then examines the pigmentation of mollusks, carbohydrate and nitrogen metabolism, physiology of the nervous system, and sense organs. Topics include indole pigments, sugar and polysaccharides, metabolism of nitrogenous compounds, terminal products of nitrogen metabolism in mollusks, and synaptic transmission. The selection is a dependable reference for readers interested in the physiology of mollusks.

Book Description
"Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History

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.

Book Description
The phylum Mollusca is the second largest group of animals (after Arthropoda) and they occur in virtually all habitats. In this volume general chapters draw from a diverse and extensive literature on molluscan physiology, natural history (including ecology), and interactions with humans.

Book Description
Bivalve Molluscs is an extremely comprehensive book coveringall major aspects of this important class of invertebrates. As wellas being an important class biologically and ecologically, many ofthe bivalves are fished and cultured commercially (e.g. mussels,oysters, scallops and clams) in a multi-billion dollar worldwideindustry. Elizabeth Gosling who has a huge wealth of research, teachingand hands on experience working with bivalves, has written alandmark book that will stand for many years as the standard workon the subject. Chapters in Bivalve Molluscs covermorphology, ecology, feeding, reproduction, settlement andrecruitment, growth, physiology, fisheries, aquaculture, genetics,diseases and parasites, and public health issues. A fullunderstanding of many of these aspects is vital for all thoseworking in bivalve fisheries and culture. An essential purchase for anyone concerned with this importantclass of animals, copies of Bivalve Molluscs should be onthe shelves of biologists, ecologists, environmental scientists,fisheries scientists and personnel within the aquaculture industry.Copies of the book should be available in all libraries andresearch establishments where these subjects are studied ortaught. Elizabeth Gosling is based at the Galway-Mayo Instituteof Technology, Galway, Ireland.

Book Description
This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism ( 24%), protandry (
