Ghost sharks, also known as chimaeras, are cartilaginous fish related to sharks and rays sharing a common ancestor dating back some 400 million years. These extraordinary fish are found in virtually every ocean on the planet, and while a few inhabit coastal waters, most live at depths that can make them incredibly difficult to study and observe. This comprehensive reference book covers every known species of chimaera to date. Illustrated with spectacular photos, detailed drawings, and informative diagrams, Ghost Sharks is the essential guide to this enigmatic order of shark-like fish.
