Expanding the coverage of its preceding volume (2004), this new book considers how elasmobranch fishes, the sharks, skates, rays, and chimaeras' successfully survive in the wide range of habitats in which they live. It examines the particular suitability of integrated sensory systems and the resultant perception of their surroundings. This resource also discusses the stresses and behaviors that prevent elasmobranchs from inhabiting some oceanic realms and the adaptations that allow many other elasmobranch species to exploit virtually all aquatic realms, from marine and freshwater habitats, to tropical and Arctic waters.
