With their long, shaggy hair and massive 800-pound bodies, musk oxen are built to withstand the cold, harsh conditions of the tundra. Musk oxen are herbivores, able to nourish themselves on the scarce vegetation that grows in this barren landscape. In this book, readers will learn about the musk oxen's adaptations to survive in the Arctic, its behavior, life cycle, and more. Eye-catching photographs bring the information to life and helpful features highlight key concepts such as interdependence of species.
