Have a great weekend folks, now that our keepers have generously returned a bit of freedom. I’m gonna get a haircut and eat cheeseburgers, and I dare anyone to stop me. See you back here tomorrow unless the apocalypse is expedited.
The Astonishing Annual Red Crab Migration
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.
The red crab is by far the most obvious of the 14 species of land crabs on Christmas Island. Every year over 150 million red crabs move from inland shelters to the shore for their annual breeding season. This occurs at the beginning of the wet season (usually October/November).
That synchronized QuadriCombo of .gifs makes for a stand-alone post here, and it’s true that some crabs suddenly materialize while others disappear into vapors. More info at this awesome site – “Colors of Fauna.”
