Ebert, David A. & Sarah Fowler (text) & Marc Dando (illus.). A Pocket Guide to Sharks of the World. Princeton Univ. 2015.256p. index. ISBN 9780691165998. pap. $19.95. In this condensed version of the authors' Sharks of the World, every known shark species is described by key identification features and shown in a color illustration. The guide lists the regions in which the species lives, its habitat, and its status on the IUCN (International Union for Conservation of Nature) Red List of Threatened Species. An exhaustive, step-by-step guide describes how to identify sharks based on a variety of characteristics and two sections cover ways to recog-nize the creatures using only their fins, which are heavily traded to make shark-fin soup, or by teeth, which are shed by the fish throughout their lives. Instructions for recording shark observations for field research purposes are also provided. The presentation closes with information about topography, a glossary, and a list of further reading. VERDICT This well-organized, well-written guide is ideal for scholars, professionals, and enthusiasts. Leonard Compagno et al's Sharks, while slightly older, is an engaging introduction for beginners.
