Who rules the Nile, hippos or crocodiles? When a predator catches prey in the wild, the result is often a meal for the predator. But many prey animals are just as tough as the predators trying to eat them. Find out why crocodiles hunt young hippos but generally avoid adults. Discover how zebras protect themselves from hungry lion prides. Readers will compare the animals’ size, weapons, and habits, and then make their own decisions about which animal rules the habitat. Sidebars, amazing color photos, a vibrant design, and strong STEM connections make this series a wild feast for customers.
