An unprecedented look at a dangerous predator, this is the second of three natural history programs hosted by Sir David Attenborough. Surviving virtually unchanged since the days of the dinosaur and found throughout the world, these remarkable creatures have the tools for survival. Long known as vicious hunters, new photographic techniques now allow us to see them cooperating with each other and protecting their families. From tiny babies hatching from the shell we see them grow into great beasts capable of standing up to the lion and bringing down a zebra. BBC production in association with WGBH.
