Transcription: Living in the branches has meant the tree kangaroos have had to develop a few novel features. For instance, they can move their hind legs independently and their ears aren't as movable as those of the ground-dwelling kangaroos. They never look too sure of themselves up in the trees. That is, until they decide on a leap like this. All tree kangaroos have this remarkable ability. They can survive vertical leaps of up to 18 meters, almost 60 feet.
