(4) 4-6 Illustrated by Sergio Ruzzier. Purported "undiscovered" creatures, including Bigfoot, the Cadborosaurus, and the Jersey Devil, are described in terms of reported sightings, origin theories, and scientific debate. Both believers and naysayers are cited, allowing readers to draw their own conclusions at the end of each stand-alone chapter. The anthropomorphic, slightly goofy illustrations don't match the text's clear-cut tone of scientific inquiry. Reading list, websites.
