Why did the crab cross the road?
The Christmas Island red crabs (Gecarcoidea natalis) climb over an overpass to cross a road on Christmas Island during their migration.
These crabs live in burrows in the rainforest and when the wet season starts and the tide is right, over 65 million crabs start their mass synchronized 8km migration to lay their eggs in the sea. The crabs are single minded on their mission, with little care for obstacles such as car wheels. Handy then that they are getting a little help :)
