Mammals are a wild bunch, ranging from rodents and rabbits to mega creatures like elephants. Kids can find out all about them on a journey that spans the globe, from the icy Arctic to sweltering deserts to sweeping savannahs and deep oceans. Along the way, they’ll discover what mammals are, how they survive in such diverse environments, and key information about each animal. Includes fun interactive items, "How Big?” boxes to show relative size, dramatic photos, and a special Ecowatch feature highlighting threats to each mammal’s survival.
