For fans of animals that are the exceptions to most rules, this fun series highlights the peculiarities of readers' favorite amphibians, birds, fish, invertebrates, mammals, and reptiles--from immortal sea creatures to bugs that see their whole life in a few hours. High-interest foci like limb regrowth and topical insects such as the 17-year cicada are covered, while the series also still addresses the major facets of each classification of creature. Titles feature short facts alongside the meatier discussions and highlighted vocabulary for scientific literacy, boosting, and retention. Back matter includes a glossary, "Read More" section, websites, and index. VERDICT These books are an exciting must-have for middle graders interested in the exciting aspects of the life sciences.--Lisa Bosarge, Enoch Pratt Free Library, Baltimore "School Library Journal"
