Sharks and Their Relatives II

Expanding the coverage of the 2004 volume, this new edition considers how elasmobranch fishes - the sharks, skates, rays, and chimaeras - successfully survive in a wide range of habitats. 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.

Examines how elasmobranch fishes - the sharks, skates, rays, and chimaeras - successfully survive in a wide range of habitats. This title explores the physiological adaptations that make these animals particularly well suited for the range of habitats where they are found, in both oceanic and freshwater realms.
