Millions of Red Crabs Migrate, Shutting Down Roads on Christmas Island
Every year, millions of red crabs on Christmas Island go on a big walk!
This walk happens in October and November.
They leave the forests and travel to the ocean.
This journey is very important because they need to lay their eggs in the water.
To help the crabs cross safely, special roads are closed, and barriers are put up.
This way, cars don't hurt them, and they can get to the ocean to have baby crabs.
The whole trip takes about one to two weeks.
Millions of red crabs undertake an annual migration on Christmas Island.
The migration occurs each year in October and November.
Crabs travel from the island's forests to the Indian Ocean to breed.
Roads are closed and barriers are installed to protect the migrating crabs.
The migration journey lasts for one to two weeks.
