Red Crab Migration
On 23 October 2025, millions of red crabs have began their yearly migration across Christmas Island, close to Australia.
The amazing and cool yearly event takes around 50 million crabs travel from their houses to the ocean to lay their preicious eggs.
Crab bridges have been built on the island to help the crabs get around tricky things such as roads, radio stations provide the people there with an update on the mass crab movements.
The crabs leave their burrows when the moon is in its third quarter phase and with the first rainfall of the wet season.
The red crabs go to the ocean to mate at the best time to make their eggs hatch. Once they mate, the female crabs stay in burrows on the beach for a sevral weeks until their eggs hatch.
When the Moon reaches its final quarter and the tide is high, the female crabs will head into the water just before dawn to lay their eggs which hatch straight away into tiny crab larvae.
With that done, the female red crabs head back home into the forests.
