Blue Whales (Nature's Children)

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. Readers will discover what role the blue whale plays in ocean ecosystems and how humans have affected this remarkable species.
