Life in Cold Blood

Life in Cold Blood', is the latest landmark series about reptiles and amphibians and it will complete David Attenborough's overview of the animal kingdom. Key to this series is new behaviour that has never been filmed before. Under the Skin gives an extra, privileged and personal look at these fascinating sequences. They offer an emotional and intellectual insight into "how we know what we know" about reptiles and the voyage of discovery that led to this knowledge.

Out in the field David Attenborough works with the passionate scientists, at the cutting edge, who help to bring unique behaviour to our screens.

The more science reveals about reptiles and amphibians the more the myths and misconceptions about them are dispelled. They are surprising animals, as passionate in their courtship, as aggressive in their rivalry and as tender in their parental care as many warm blooded creatures.

And they have they been amazingly successful with over 350 million years of history on the planet.

What are their secrets and how have they been uncovered?
