Summary

Marine life at the poles, where winter temperatures frequently fall to a numbing -40C. Even when the sun reappears in the spring, its weak rays take a long time to melt the ice. David Attenborough describes how wildlife including seals, whales, polar bears and penguins overcome the elements to survive through prolonged cold spells.
