Migration of red crabs in Australia

A massive migration of red crabs has begun in Australia. On Christmas Island, about 50 million endemic red crabs (Gecarcoidea natalis) move from the jungle to the ocean to breed.

Christmas Island is located 1,600 kilometers northwest of mainland Australia in the Indian Ocean. During the migration period, tens of millions of crabs move both through forests and along highways. For their safety, temporary bridges have been built, and some routes are completely blocked to allow crabs to pass. Migration of crabs begins during the rainy season, usually in October or November. Crabs need about 18 days to reach the shore.
