Why do lemmings drown by the thousands as they travel to find food? Why do frogs risk death crossing our highways? When polar bears migrate, are they moving across the ice, or is the ice moving them? Seymour Simon and Elsa Warnick team up again to bring to life the fascinating creatures that endlessly search for food, water, and safety.
