Life in Cold Blood

Show Summary

From a purely biological standpoint, cold-blooded amphibians and reptiles long have commanded the respect of scientists for their sheer resilience, if nothing else. These animals dominated the world for an estimated 200 million years, and today, more than 14,000 species of them still thrive. This series, hosted by David Attenborough, examines these creatures in a new light, however, revealing them to be complex, social and passionate animals.
