Gr 2–4—This eclectic assortment of creatures showcases typical animal life cycles. Each title begins with background information about the genus's appearance, eating habits and habitats, plus common species. Life cycle sections begin with mating habits. (Only Frog uses the term "fertilize" while the other titles use "mate.") The cycle includes care and feeding, and growth and development, followed by adulthood. Closing pages report on the animal's current status and include any special features such as "Poison" in Frogs and "Playing Dead" in Opossums. The cycle is recapped in a photo sequence. Captioned, full-page photographs and "Awesome Animal!" fact boxes add information.
