The very latest technology enables extraordinary and previously unseen behaviour 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. As with Life in the Undergrowth, this series will change the audience's perceptions forever - giving them a new, warm-hearted relationship with Life in Cold Blood. Welcome to BBC EARTH!
