Hippos are perhaps the most surprising animals in this set about voracious biters. They are, after all, herbivores, not carnivores or even omnivores. Their huge body and short, fat legs make them look slow moving rather than pouncing and powerful. Yet these enormous animals are surprisingly speedy, aggressive, and equipped with an immensely powerful bite. Young readers will be enthralled with what they discover about this popular animal. An accessible narrative and fact boxes address important science concepts. A graphic organizer and bold photographs enhance this wildlife learning experience.
