Gr 3-6-The nature and habits of two nocturnal predators are clearly delineated in these succinct introductions. Each one briefly describes its subject's major physical characteristics, natural enemies, and relationship to humankind. Miscellaneous facts are also offered in a few extended picture captions. While the books are clearly written and well organized, the photographs are less satisfactory as they do not always match the texts. For instance, in Anacondas, a photo of a solitary snake coiled on a log accompanies a caption describing "Breeding Balls," a behavior in which up to a dozen males wrap themselves around a female to mate. In Bats a photo of a furry lump that might be a bat caught in a net appears above a caption describing the use of anticoagulants to control bat populations. Two pages of "Fast Facts" at the beginning of each title highlight basic information (average size, weight, etc.), while a "Myth versus Fact" page contrasts several fear-inspired beliefs that people have with scientific findings. A shaded world map shows the featured animal's geographic range. Dorothy Hinshaw Patent's Slinky, Scaly, Slithery Snakes (Walker, 2000) and Laurence Pringle's Bats (Boyds Mills, 2000) are good general introductions, but they do not provide as much detailed information on these specific animals. Therefore, these new titles will help fill a gap.-Karey Wehner, formerly at San Francisco Public Library Copyright 2001 Cahners Business Information.
