Christmas Island red crab
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 once 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. Christmas Island red crabs are well known for their annual mass migration to the sea to lay their eggs in the ocean.〔
==Description==
Christmas Island red crabs are rather large crabs with the carapace measuring up to wide.〔 The claws are usually of equal size, unless one becomes injured or detached, in which case the limb will regenerate.〔 The male crabs are generally larger than the females, while adult females have a much broader abdomen (only apparent above 3 years of age) and usually have smaller claws.〔 Bright red is their most common colour, but some can be orange or the much rarer purple.〔
