Find out fascinating facts about one of the most incredible species alive today. Nature's Children series provides young readers (Ages 8-10) with fascinating information about the planet's most incredible wildlife species. Each title offers a complete picture of the animal- from birth to adulthood- and describes its place in our world, including how humans impact it and its environment. Likely larger than any other animal ever found on Earth, the blue whale is one of the most incredible species alive today. This gentle giant can weigh as much as 300,000 pounds, but it is far from fearsome, subsisting entirely on a diet of tiny krill, and preferring to avoid dangers by fleeing.
