The Reality Reports

Nature's Most Spectacular Journey: Deep in the Indian Ocean, Christmas Island becomes the stage for one of Earth's most remarkable wildlife events. Each year, between October and January, an estimated 40 to 50 million bright red crabs emerge from the island's forests and begin a synchronized march toward the coast.  This mass migration transforms the entire landscape into a moving carpet of crimson as the crustaceans travel several miles to reach the ocean. The phenomenon depends heavily on rainfall, with the crabs typically beginning their journey at the start of the wet season when humidity is high enough to prevent them from drying out during the trek.
