Caribou, also known as wild reindeer, live in the cold, snowy tundra, where food is scarce. Their specially shaped hoofs help them walk on snow and dig for the food underneath it. What do caribou eat? How do they avoid dangerous predators? Readers will find the answers to these and other questions in this engaging text, which supports basic elementary science curricula. Full-color photographs of caribou in their natural habitat make readers feel as if they are on their own expedition to the frozen tundra.
