Roads turned red this week as millions of red crabs on Christmas Island emerged from the centre of the island for their annual migration journey on the island off the coast of Western Australia. With a population of over 100 million, the crabs are unique to the island — much of which is designated as a national park — and protected by Australian law. The migration, that usually lasts for days, sees the crabs journey from the island off the coast of Western Australia to the ocean, where they mate

Tens of millions of red crabs are crawling their way to the ocean as part of their annual migration on Christmas Island. On the island is a much smaller human population that uses leaf blowers and garden rakes to help the crabs on their way. | AP
