A veritable who's who of the animal kingdom shows off its moves. Each spread features one action demonstrated by two distinct animals. (Both a whale and an armadillo swim. Both a crocodile and a snake slither.) Each animal, in turn, performs two different actions. (A polar bear both floats and slides.) The clever layout introduces a pleasing element of suspense and gives the book a page-turning momentum. The paper collage illustrations depict the animals in realistic detail with rich textures and bold colors. It's a read-aloud romp for all ages: babies can enjoy the animal movements and sounds, toddlers can act out the motions, and older kids can have fun predicting what each creature will do next. Many of the animals are identified at a level of specificity (a gibbon, a jacana, a blue whale, a jumping spider) that's sure to inspire curious young scientists, and the brief appendix of facts offers a springboard to further zoological inquiry.
