A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.
