Allen (an author, no university affiliation) separates the facts about sharks from the horror-movie lore. He explains how sharks select victims and outlines factors contributing to or mitigating the severity of an attack. Survivors discuss their experiences, and marine biologists present the available data. Chapters describe attacks in California, Hawaii, South Africa, Australia, in rivers, in lakes, at sea, and on the shore. They also discuss prevention, and survival. Appendixes list popular and scientific species names and instructions for reporting an attack.
