Christmas Island's famous red crabs started their annual migration this week - much earlier than before.
For those that have never witnessed this event, you would be forgiven for thinking that it is more like something out of a horror movie than real life... more than 150 million crabs travel more than three miles through city streets, shops and schools. Check out the video to get a feel of what it might be like in real life. (feeling hungry yet?)
