The Christmas Island red crab Gecarcoidea natalis is a species of land crab that is endemic to Christmas Island and the Cocos (Keeling) Islands in the Indian Ocean. Although restricted to a relatively small area it has been estimated that 43.7 million adult red crabs lived on Christmas Island alone but the accidental introduction of the yellow crazy ant is believed to have killed about 10–15 million of these in recent years.
