Each episode features two creatures with curiously distinctive adaptations that link together via a common theme. From the emperor penguin and the wood frog, both of which survive in conditions so cold they seem to defy the laws of nature, to the rhino and the hedgehog - two animals that hide behind seemingly impenetrable armoured coats.
The first series of David Attenborough’s Natural Curiosities was the highest rating programme ever on Eden, and the whole series reached 1.6 million individuals.
In series one Sir David revealed the stories of the creatures whose biology intrigues him the most. In this longer 10-part 30 minute episode series we will continue to shine the spotlight on some of nature’s most extraordinary and baffling species.
