The Cold-Blooded Truth
Statement of responsibility
narrated by David Attenborough
Reptiles and amphibians are as dramatic in combat, colourful in their communication and tender in their parental care as other animals. They also live their lives on a totally different time scale and harness their energy from the sun. The Cold Blooded Truth reveals the secret of their success. Sir David Attenborough begins the story on the Galapagos Islands, among massed ranks of marine iguanas. Stunning thermal imagery reveal how these lizards bask in the sun until they are as warm as he is, and then pour like hot golden lava into the cold sea as the heat they have accumulated powers their dives. In California, side-blotched lizards fight for the best sun-baked rock-piles to use as radiators. Here, the females choose the males with the hottest rocks as mates. Mediterranean wall lizards have also discovered a novel heat source. They bask on the bizarre Dead Horse Arum flowers that produce living heat as a by-product of making a disgusting odour to attract flies. Sat on theses hotplates, the lizards get heat and regular meals of flies. Surprisingly, on a chilly, windswept island off the coast of South Africa, David finds a riot of reptiles {u2013} the highest concentration of angulate tortoises on Earth. They, too, sunbathe to power their hot-blooded jousting, using 2lances3 on the front of their shells. A 2tortoise cam3reveals just how they flip each other over in these vicious fights. But reptiles don{u2019}t waste their energy, and they use solar power very efficiently. Snakes will remain still for days before striking with lightning speed. They can switch instantly from 2pilot light3to 2full power3, and their bodies respond with a biochemical explosion of activity. Amazingly, their livers double in size in two days and their hearts can grow by 40%. Reptiles can be sensuous, too {u2013} the tenderest courtship is surprisingly performed by the ultimate cold-blooded killer on Earth today {u2013} the saltwater crocodile. The five-metre-long gigantic male gently caresses the much smaller female while blowing bubbles to reassure her. Having revealed the truth about life in cold blood, David looks at some possible exceptions to the rule. After examining the oldest reptiles of all, the dinosaurs, he finds that they collected heat just like their modern relatives using solar panels. But that the sheer size of the Tyrannosaurus rex would have helped it retain heat so well that it was effectively warm blooded. Finally, David meets a modern giant reptile that is also an exception to the cold-blooded rule. The ancient leatherback turtle is the largest of living reptiles. As the female lays her eggs, thermal cameras reveal that her internal body temperature is above that of her surroundings
