Each year millions of bright red land
crabs leave their burrow homes on
Australia's Christmas Island and start a
long, laborious trek toward the sea.
They descend cliffs, climb banks and
maneuver around obstacles to reach
the shoreline and lay their eggs,
eventually returning to the island's
central plateau with their offspring in
tow. The synchronized migration
resembles a crimson-colored river
undulating across the island 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 tide and the arrival of the
waning moon.
