Produced in association with the Discovery Channel, this documentary has assembled some of the most fascinating facts now known about the animals on this planet.
The film footage is fabulous, and the explanatory graphics help us understand how the survival mechanisms of certain animals work.
Starting with the harsh temperatures of the Arctic winter, we see how polar bears endure the climate with their protective layers and acute sense of smell.
The film then moves south to Antarctica, and to penguins and how they survive. The extraordinary vision of the eagle is examined, and the keen olfactory talents of the wolf and salmon.
