Summary

Reptiles and amphibians ruled the world for nearly 200 million years and today there are over 14,000 varieties of them. Some are huge – among the deadliest creatures on Earth; others are tiny and number among the strangest.

Where did these ancient creatures come from? How have they transformed themselves into the bizarre and beautiful forms alive today? And what is the secret of their epic success?

From the largest and most dangerous reptiles on Earth demonstrating tender and sensual courtship, to tortoises and horned chameleons jousting dramatically, flashing anolis lizards and waving Jacky dragons, the Life In Cold Blood team use the very latest technology to capture previously unseen behaviour.

The perception that cold-blooded life is slow, solitary and primitive is overturned and these creatures are revealed to be as dramatic, social, sophisticated and passionate as warm blooded animals.
