"The biggest heart in the world is inside the blue whale. It weighs more than seven tons. It’s as big as a room. It is a room, with four chambers. A child could walk around in it, head high, bending only to step through the valves. …There are perhaps ten thousand blue whales in the world, living in every ocean on earth, and of the largest mammal who ever lived, we know nearly nothing. Nothing is known of the mating habits, the travel patterns, diet, social life, language, social structure, diseases, spirituality, wars, stories, despairs, and arts of the blue whale. But we know this: the animals with the largest heart in the world generally travel in pairs, and their penetrating moaning cries, their piercing yearning tongue, can be heard underwater for miles and miles."
