In an annual spectacle of nature that draws the attention of wildlife enthusiasts and adventurers from across the globe, Christmas Island is currently hosting its breathtaking red crab migration. This natural phenomenon, which is influenced by the lunar cycle, tides, and weather patterns, features tens of millions of red crabs as they embark on their epic journey from the island’s lush rainforests to its coastal shores.
Located 1,500 kilometres off the coast of the Australian mainland in the Indian Ocean Territories, Christmas Island is the stage for this extraordinary event. This year, the migration is particularly noteworthy due to the El Niño weather phenomenon, which has delayed the usual onset of the wet season and led to sporadic rainfall. Nonetheless, the island’s iconic red crabs have made their appearance, much to the delight of locals and visitors alike, who have eagerly awaited the event dubbed the “great scarlet curtain” by none other than Sir David Attenborough. Attenborough, a renowned naturalist, has famously included the migration in his top 10 television moments, captivated by the sight of red crabs navigating cliffs and rocks to reach the sea.
The migration’s timing is closely tied to the island’s climatic conditions, usually kicking off with the first rains of the wet season. This year, the crucial spawning event, during which each female red crab releases up to 100,000 eggs into the Indian Ocean, is expected around 4 February. Approximately one month later, the hatched baby crabs will make their way back to the island, continuing the cycle of life that has fascinated scientists and nature lovers for decades.
David Mulheron, Chair of the Christmas Island Tourism Association and owner of Freedive CI, expressed his enthusiasm for the migration, noting it as a testament to the island’s natural wonders. “The red crab migration not only showcases the unique wildlife of Christmas Island but also highlights the island as a prime destination for nature enthusiasts,” Mulheron said. He emphasised the island’s commitment to preserving this ecological marvel and extended a warm invitation to visitors worldwide to explore the island’s diverse natural attractions.
