Christmas Island Red Crab
October 8th 2010 03:10
As reported on the Telegraph, British scientists have discovered what triggers one of the most spectacular migrations on Earth – the rush to the beach of the Christmas Island crabs.
The crabs, which usually complete just 10 minutes of daily exercise, travel for up to 12 hours a day, to mating grounds near the sea.
British researchers have now discovered that the incredible journey is only possible because the six inch crabs rely on sugar reserves stored in their bodies, which they convert into energy when a hormone kicks in.
