The koala, the famed marsupial of Australia, is unlike any other animal in that it actually has two opposable thumbs. These thumbs are set at an angle to the three fingers. The koala uses these two sections of its hand – the thumbs and fingers – to securely grasp and climb tree branches. Koalas also have an opposable toe on each foot. That earns them the world record of having six opposable digits!
