Rachel: It is without challenge the most powerful animal on the globe. The killer whale. He is a mammal with warm blood, found in every sea. The ancient Romans called him Orca Orcinus Latin for "The Bringer of Death". His tapered form and muscular fin make the orca the fastest moving whale in all the oceans. The adult male measures around 30 feet and weighs six tons but there have been cases where he ran to 45 feet. Now here is a killer whale and what is probably his most familiar guise: Tamed, on exhibition. One captured as a pup and brought up with men. Treated with kindness, there is no creature that is a greater friend to man. But if not.. the orca's mouth has 48 teeth set in two impressive rows. As parents, killer whales are exemplary. Better than most human beings. And like human beings, they have a profound instinct for vengeance. Yet the most amazing thing about these creatures is neither their gentleness nor their violence, but their brains. Slides, please, Ken. Now these three brains are of a monkey, a human being, and this is the brain of a killer whale. We know very little about the nature of the whales intelligence except that it exists and is powerful and in some respects may even be superior to man. A four-month-old fetus, incredibly like that of a human baby. It even has two hands, with five fingers on each. Whales talk. They communicate by a combination of pure sound and sonar echolocation. The whale sounds you are now hearing contain wavelengths that can travel not just across one ocean basin, but around the entire world. This was recorded under water and analyzed by computers at CalTech. It was found to contain 15 million pieces of information. The Bible contains only 4 million. What are they saying? For that matter, do they have to say anything to communicate? Their sonar would be a little like our having X-ray vision. If we could look into one another and instantly know if someone else was happy or sad, indifferent or aroused, healthy or suffering from a tumor we could actually see then a human phrase like, "How are you?" would be meaningless. What we call language they might call unnecessary, or redundant, or retarded
