From insects to fish to reptiles, “Animal Battles” envisions what would happen if two predators went head to head. Before the battle, an overview is provided of the competitors, including their physical characteristics, “secret weapon” adaptations and features, and common attack moves. Graphs and charts bring the animals to life with important information like their size, habitat, range, and speed. Fun facts about these formidable opponents are sprinkled throughout, and the books include a notable amount of animal facts on top of the high-action concept. The end of each book features a short fight scene imagining the brawl, though this could be expanded upon for maximum impact. The page layouts, which include bold, colorful graphics and full-page photographs of the animals, emphasize the exciting subject matter. This will entice both upper-elementary audiences and striving readers at the middle school level. VERDICT Written at a third grade reading level, this series winningly combines a fun, high-octane concept with readable text and in-depth information.
