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. Christmas Island red crabs eat mostly fallen leaves and flowers, but will occasionally eat other animals, including other red crabs if the opportunity arises. Christmas red crabs live in burrows for shelter from the sun. Since they breathe through gills, the possibility of drying out is dangerous. They are famous for their annual migration to the sea to lay their eggs in the ocean. This event is often described as one of the world’s most impressive wildlife migrations and has to be seen to be believed. See this post for more on this amazing migration!

Christmas Island, a small Island in Indian Ocean, is home to about 120 million Red Crabs (see this post for more on these beautiful crabs) which migrate from the forest to the coast each year during the breeding season. At the start of the annual rainy season (last quarter of each year), fully grown Red Crab begin their migration from their burrows in the forest to the coastal areas of the Island. It is thought that biological programmimg triggers the migration and almost entire adult population of Red Crab (about 50 million) starts moving almost simultaneously to try to reach the coast at the time of high tide during last quarter of the moon in the rainy season. At the coast the female crabs release their eggs in water and once the eggs hatch the young crabs alongwith the adults start back their trek to the forest. During the migration, the crabs cover the routes to the coast so densely that from the air the entire island looks like a creepy crimson carpet. The to and fro migration takes about 3-4 weeks and during this period the crabs are almost every where - one the road, in the house, on the lawns, on the beaches and even in the public lavatories. During migration some roads are closed to the vehicular traffic and national park rangers/volunteers erect temporary barriers to control the juggernautic movement of red crawleys. The entire event is often described as one of the world’s most impressive wildlife migrations and has to be seen to be believed.
