A Mammal's ability to learn new tricks is the key to survival in the knife-edge world of hunters and hunted. In a television first, a killer whale off the Falkland Islands does something unique: it sneaks into a pool where elephant seal pups learn to swim and snatches them, saving itself the trouble of hunting in the open sea. Slow-motion cameras reveal the star-nosed mole's newly-discovered technique for smelling prey underwater, young ibex soon learn the only way to escape a fox, and young stoats fight mock battles, learning the skills that make them such an efficient predator.
