Sperm Whales Shouldn't Exist.. So Why Do They?

 In this video we explore the full story of the sperm whale — the deepest diving predator on Earth, the owner of the largest brain in the history of life on this planet, and an animal whose biology, behavior, and intelligence violates almost every rule we use to define what's possible for a living thing. We cover the physics of deep diving, the collapsed lungs and slowed heart, the spermaceti organ and 230 decibel sound weapon, the hunt for giant squid in total darkness, the language researchers are only now beginning to decode, the matriarchal social structure, the whale pump that keeps Earth's oceans alive, and the whaling industry that nearly erased all of it.
