Written and presented by David Attenborough, Life in Cold Blood tells the epic story of the most enduringly successful animals ever to walk on land - reptiles and amphibians. The very latest technology enables extraordinary and previously unseen behavior to be captured in intimate detail, overturning the myth that cold blooded life is slow, solitary and primitive, and revealing these creatures to be as dramatic, social, sophisticated and passionate as warm blooded animals.
