Internal fertilization is universal in chondrichthyan fishes and, as such, requires a suite of biological activities, including behavioral, morphological and physiological mechanisms, to ensure successful copulation and fertilization. This volume correlates available data and ideas concerning the development, reproductive morphology, function, and

"Of all the literature I use while preparing field guides for the Food and Agriculture Organization of the United Nations, Nelson's Fishes of the World is, by far, the one I refer to most often. [This] book is a standard reference . . . I continue to use it extensively in the ichthyology courses I teach, particularly in laboratory sessions." -Kent E. Carpenter Old Dominion University "Fishes of the World is a unique and essential resource for anyone seriously interested in the diversity and evolution of fishes. The family accounts provide quick summaries of current knowledge on all groups of living fishes and many key fossil taxa. It is a required work for every student in my laboratory." -William E. Bemis Kingsbury Director of Shoals Marine Laboratory, Cornell University "Only classics are known by the single name of their author, and certainly [Nelson's book] has for four editions been such a book for all those who seek an accessible, up-to-date, readable reference on fish classification. Once again, Nelson presents a balanced view of the sometimes tumultuous, but ever-exciting, study of the phylogenetic relationships and classification of fishes. In doing so, Nelson makes an excellent case for organismal biology, highlighting the many and varied morphological characters we use to diagnose fish taxa and differentiate among the 515 families of living species." -Lynne R. Parenti Curator of Fishes and Research Scientist, National Museum of Natural History, Smithsonian Institution Fishes of the World, Fourth Edition is the updated edition of a true classic in the field. A unique presentation of a modern, cladistically based classification of all the major living and fossil fish groups, this indispensable reference helps scientists and others identify and classify specimens, make familial connections, understand the evolution of fishes, and springboard into further research. The taxonomy of fishes presented includes the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships for all 515 families of living fishes. Packed with representative species drawings and information on phylogentic relationships, this informative Fourth Edition features: * Both fossil and extant species * More than 500 illustrations * Fully vetted scientific and common names * An extensive bibliography

Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.

This book deals primarily with the principal extracellular macromole cules of animal connective tissues. It attempts to answer some general questions about the biological organization of the tissues: What is the nature of this organization at various dimensional levels? What functions does the organization serve? How has it evolved? I have given major emphasis to the structures and properties of the macromolecular components of extracellular matrices from a wide range of invertebrates and vertebrates. In doing so, however, I have treated cursorily many important aspects of connective tissue biology that appeared to be only indirectly relevant to the principal questions asked. On the other hand, I have not hesitated to search for broad biological principles outside the prevailing conceptual boundaries of animal connective tissues and the lower molecular dimensional levels. The numerous speculations presented will, I hope, stimulate the reader to further thought and investigation. Acknowledgements My previously unpublished data that have been included in this volume could not have been obtained without the generous gifts of specimens and other assistance by a number of individuals and institutions.
