Tens of millions of red crabs are migrating to the ocean on Christmas Island, assisted by the local human population. With up to 200 million crabs present, the migration is triggered by the Southern Hemisphere summer rains. The crabs navigate roads and gardens, causing some inconvenience for residents, but many view the event as a privilege. The male crabs create burrows for females to lay eggs, which hatch into larvae before returning to the island. Locals use leaf blowers to help the tiny crabs safely reach the shore.
