For many years, brief encounters between sharks and humans could leave the latter with a vivid memory of the much-maligned fish but no convenient means of identifying it more specifically. With the publication of The Sharks of North American Waters in 1983, everyone from the experienced ichthyologist to the weekend angler had access to concise descriptions and accurate, detailed drawings in this handy field guide to more than one hundred species. All species that have been reported within five hundred nautical miles of U.S. and Canadian shores (plus a few deep-water species from adjacent areas) are illustrated, with summaries of diagnostic characteristics, similar species, geographic range, biology, reproduction, utility, and fishing methods. An illustrated key to the families of sharks, family descriptions, and species characteristics makes field identification simple. Also included is a general account of the evolution of sharks, their anatomy, reproduction, and distribution.

This memoir attempts to give concise descriptions of all the fish species known to inhabit the waters of North America, north of the boundary between the United States and Mexico. The classification system adopted is essentially based on the views of Professors Gill and Cope rather than the fish groupings offered by the European systematists, with an effort to avoid unnatural associations in genera and families on one hand and subdivision beyond reasonable limits, on the other. Genera which have defied precise definition are rarely adopted.

Capture records of 109 white sharks caught along the western coast of North America indicate the following life history pattern. Adult females give birth to pups during the late summer and early fall south of the Point Conception to live both inshore or offshore at islands. As females continue to grow, they move back south of Point Conception yet remain offshore probably to give birth to young. It is believed that the areal distribution of the shark is governed by the availability of pinniped prey for adults and possibly the need for pupping grounds with few predators and competitors. The area with the highest abundance of sharks is the coastline within the Point Reyes/Farallon National Marine Sanctuary. A multisensor, computer-interfaced telemetry system has been built. Transmitters have sensors for monitoring swimming speed, depth, surrounding water temperature, and light level. Expansion board hardware converts pulsed telemetry signals to TTL logic. Software has been written to: (1) convert time intervals into sensor values, (2) display 8 channels of sensor values either numerically or graphically, (3) display sensor values of a single channel graphically with high resolution, and (4) store the sensor data on floppy disk. The system will be used to describe predation by the white shark on pinnipeds and orientational behavior in pelagic sharks.

This is the single most historically valuable book ever written on the subject of Pacific Coast shark attacks. Through bone-chilling accounts in victims' own words, never before published photographs, and detailed maps and charts of attack locations, this book accurately chronicles every known unprovoked shark attack that occurred along the Pacific Coast of North America during the entire Twentieth Century. The author's examination of wound characteristics, recurring locations, and the curious phenomenon of attacks on inanimate objects afford astonishing insights into why sharks attack. These insights form the foundation for his safety recommendations to specific ocean user groups. Based on 40 years' of research, this book willl be of inestimable value to scientists, researchers and educators, as well as anyone that might venture into the waters off the Pacific Coast. The understanding gained from this book will temper fears with knowledge and provide the reader with clear and specific information that may easily make the difference between life and death.
