Seventeen experts scientists, artists, marine photographers collaborate in a whale of a book about this greatly feared denizen of the seas. The first section introduces us to shark evolution, biology and behavior; we learn about major groups of sharks, their distinguishing characteristics and distribution. The second section reviews shark attacks worldwide (most attacks occur in the afternoon, 2-6 p.m.). The most dangerous beach in the world is Amanzimtoti, near Durban, South Africa. Antishark measures like nets are expensive and only partially successful. In the third section, marine artist Richard Ellis examines the shark in legend, literature and art. One essay discusses the commercial value of sharks, and another describes the preparation of shark-fin soup. Three diver/photographers tell about their experiences filming (and feeding) sharks; they regard sharks with awe. Filmmaker Marty Snyderman contributes a piece on photographing sharks, and C. Scott Johnson brings us up to date on shark repellents. This comprehensive volume is a welcome addition to the nature library. Illustrated.
