One major adaptation of mammals is part of what differentiates them from other animals: the growth and nourishment of babies inside the mother's body. Water-repelling fur, tough hides, camouflage, as well as the size and shape of various body parts are just a few other adaptations mammals have developed in order to better survive their environment. Readers learn many examples of how mammals have evolved to hide from predators and hunt for prey. Graphic organizers present even more information to aid readers' understanding while full-color photographs bring them close to animals they might otherwise only see in a zoo.
