Every year the Australian territory of Christmas Island turns into a living river of red. Around 50 million red crabs make the trek from their forest homes to the beach to lay their eggs in the ocean.
By the new year, tiny baby crabs will emerge and make the journey back to the shore, completing the cycle.
The islanders have learned to move with and around the crabs. They’ve created special bridges to help the crabs navigate around roads and other obstacles. Radio stations also give updates on their movements so that people can move around them safely.
It’s a great example of how humans can be thoughtful caretakers of the other creatures we share our home with.
