"Whales are some of the most extreme creatures on Earth The 115 foot, 150 foot ton Blue Whale, for instance, is the largest animal that ever lived. These magnificent creatures are social mammals, descended from an ancient land dweller that also gave rise to the hippopotamus family. Like hippos and humans, they are warm-blooded and air-breathing, and stay with their young, nursing them for an extended period of time. And like us, they maintain complex social networks. As you might imagine, the whale faces some special challenges doing all this in the ocean. As usual, where challenge is extreme, the solutions are efficient. So how can the Blue Whale inspire us today?
