Life in Cold Blood - Land Invaders

David Attenborough reveals the surprising truth about the cold-blooded lives of reptiles and amphibians. From steamy jungles to dry deserts, amphibians have taken their first footsteps onto land using their bizarre life histories to break their ties with the water and invade the earth. Attenborough takes a look at warring metre-long salamanders, show-off newts, and marsupial frogs, where it is the father who gives birth.
