Jäger und Gejagte (E07)

Mammals' ability to learn new tricks is the key to survival in the knife-edge world of hunters and hunted. In a TV first, a killer whale off the Falklands sneaks into a pool where elephant seal pups learn to swim and snatches them, saving itself the trouble of hunting in the open sea. Young ibex soon learn the only way to escape a fox is to run up an almost vertical cliff face. (Prime Video)
