Christmas Island Red Crab
It is estimated over 120 million crabs live on Christmas Island, which is in the middle of the Indian Ocean, near Australia.In December the millions of crabs come out of hiding and they make their way toward the ocean for their annual migration. Not all crabs live near the ocean, which means millions have to travel through the town to get there. They cross roads, lawns, driveways, the jungle, down cliffs, and even cut through houses to get to the water!
