A video on the red crabs of Australia that migrate in millions during the mating seasonAustralia's Christmas Island is known for an annual occurrence - the migration of millions of crabs. Red crabs, unique to this region, travel towards the shore via highways and major roadways in the island. Red crabs leave their burrows to mate at sea according to the lunar position, leave behind eggs and return to the forests. Once hatched, baby crabs slowly make their way home. Renowned naturalist, Sir David Attenborough described this as one of his greatest TV moments.
