In the world, there are many animals with amazing abilities. For example, the star-nosed mole has extremely sensitive outgrowths on its snout that help it quickly find prey, while an electric eel paralyzes its victim with an electric shock. Biologist Kenneth Catania tells about the strange behavior of tentacled snakes, shrews, emerald wasps, and other animals, explaining how studying them helps us understand evolution. He talks about why star-nosed moles need outgrowths on their snouts and how a tentacled snake uses cunning to catch fish. Catania also describes how an electric eel uses electricity to control other animals, and how emerald wasps zombify cockroaches. He discusses the importance of an unbiased approach to scientific research, and the fact that most animals have hidden incredible abilities.
