Each year on Christmas Island, over 100 million red crabs scurry at once from the forest to the sea to breed and spawn. For the first time tomorrow you can watch the surreal sight live from home.

IT’S AN AWE-INSPIRING sight, and now, for the first time ever, you can watch Christmas Island’s annual red crab migration as it happens live online.

Each year, up to about 120 million red crabs (Gecarcoidea natalis) scuttle to the sea from the forest across Christmas Island in an effort to mate. It is a commute which overwhelms the island – the Australian-owned island, located in the Indian Ocean 2600km northwest of Perth, has just over 2000 human inhabitants.

Males lead what is for many crabs a weeks-long journey – when arriving at the sea, they create burrows in the sand which after mating they leave to the females to lay eggs.

Tomorrow night, after two weeks of nesting – timed with the dawn of high tide during the last lunar quarter – millions of female red crabs will release up to 100,000 eggs each into the sea. They then retreat into the forest – after hatching, the young crabs will follow in their claw-steps several days after.

How to watch it

Parks Australia will live stream the expected hatching time at 8.15am AEST on Friday, 25 November (4.15am Christmas Island time).

The stream will focus on Flying Fish Cove, and is expected to go for 15 minutes – depending on the hatching.
