The Astonishing Annual Red Crab Migration.
Each year millions of bright red land crabs leave theirburrow homes on Australia ‘s Christmas Islandand start a long, laborious trek toward the sea.They descend cliffs, climb banks and maneuver aroundobstacles to reach the shorelineand lay their eggs, eventually returning tothe island’s central plateau with their offspring in tow.The synchronized migration resemblesa crimson-colored river undulating across theisland and can last up to 18 days.The event typically takes place in November or December(the crabs will only move when it’s raining)and coincides with the turning of high tideand the arrival of the waning moon.
