Nat Geo Reptiles Part 1: Lake of a Thousand Caiman ¦ 480p [2/4]

Part 1: Lake of a Thousand Caiman
Deep in the heart of the Amazon, an uncharted lake emerges every dry season when the floodwaters recede. It's rumoured that this secret lair lures reptiles that have little changed since the time of the dinosaurs. Not just a few either; hundreds gather to this far off, inaccessible place. Outsiders come here at their peril; fishermen claim to have lost limbs to fearsome monsters. Are these exaggerated local legends? Or is the veil of mystery about to be lifted on one of the Earth's largest yet least studied carnivores the black caiman?

Reptiles and amphibians ruled the world for nearly 200 million years and today there are still over 12,500 of them. Some are huge, the deadliest creatures on earth. Some are tiny, among the strangest to be found anywhere. Together, they not only outnumber mammals or birds but in their colourful variety and extraordinary behaviour, they far surpass them. So where did these ancient creatures come from? How have they transformed themselves into the bizarre and beautiful forms that are alive today? And what's the secret of their epic success?
