Gr 3–5—The series title and red-spackled page backgrounds suggest that these books will emphasize the disgusting nature of animals, but this set features general species information, including habitat, physical features, and life cycles, with only one spread devoted to cannibalism. Frequency of cannibalism varies among the featured species, so readers may gravitate more toward those where the behavior is more common. It's not always clear how often the animals eat their own kind: while it's appropriately noted that black widows rarely do so outside of laboratories, details of ground squirrel cannibalism are vague. Photographs are mostly effective, with clear close-ups that highlight other features. VERDICT All six titles are suitable resources, but Praying Mantises, King Cobras, and Bullfrogs have the strongest relation to the set theme.
