Deep in the mysterious rainforests of Papua New Guinea, hundreds of feet in the air, lives one of the most beautiful and rare creatures on the planet: the tree kangaroo. Locals refer to these elusive animals as the "ghosts of the forest."
Papua New Guinea is one of the only places in the world where you can find tree kangaroos. The only way to get an up-close look at the fuzzy marsupials is to climb way, way up into a towering tree. No one knows why or when this rare breed of kangaroos moved into the trees.
About a hundred live in zoos around the world, but these kangaroo hybrids have become endangered. Approximately 10,000 exist in the wild. Our cameras captured tree kangaroos in their natural habitat for the first time ever. From ABC News
