Annual red crab migration begins

We’re so excited – the annual red crab migration has begun on Christmas Island with millions of the creatures making their way from the forest to the coast.

The arduous process is absolutely fascinating and at times brings the island to a brief standstill. Roads can be temporarily closed with pedestrians and cars stopping to watch thousands of crabs make their way single-mindedly over obstacles to reach the sea.

On arrival at the shoreline females release their eggs, which hatch immediately upon contact with the water!

Eggs are released by the female red crabs into the sea precisely at the turn of the high tide during the last lunar quarter. Pretty amazing, heh?
