Those who think of sharks as something only found in tropical waters will be surprised to learn that there are 18 species of sharks in the cool waters of the Pacific Northwest, from the 27-inch brown catshark to the 39-foot basking shark. "Sharks of the Pacific Northwest" provides for the identification of these species, with spectacular photographs and accurate paintings and drawings, plus summaries of the sharks' classification, morphology, distribution, habitat, diet, reproduction and behaviour. It also includes a concise general account of shark evolution, anatomy and physiology, as well as discussion of attacks on humans and details of shark fisheries. It is primarily aimed at a broad, non-technical readership, but its up-to-date and detailed contents make it a useful tool for professional biologists and zoologists.
