  • Yellow Crazy Ants Kill Red Crab | Planet Earth II | BBC EarthIntroduction:In the vast expanse of the Indian Ocean lies Christmas Island, a remote speck of land that has been dominated by a unique creature for millions of years - the crab. What once were sea-dwelling creatures, the crabs have now adapted to a life on land, coexisting harmoniously in their tiny crab utopia. However, there is one event that disrupts their peaceful existence - the March of the Red Crabs.The March of the Red Crabs is a natural spectacle of epic proportions, drawing global attention to this otherwise isolated island. Every year, an estimated 50 million red crabs must make their way back to the sea to breed, creating a mesmerizing sight for both locals and visitors. It is a crucial event for the survival and perpetuation of the species.But in recent years, the fate of the red crabs has been threatened by an invader, an intruder that has established a stronghold on the island - the yellow crazy ants. These ants, which escaped from visiting ships, have thrived in the absence of natural predators, forming massive supercolonies in the island's forests.When the migrating red crabs cross into the territory of the yellow crazy ants, they face a brutal and relentless attack. The ants squirt acid into the crabs' eyes and mouths, leaving them defenseless and ultimately causing their demise. This lethal assault is not only a tragedy for the crabs but also a consequence of human actions. Humans inadvertently brought these invasive ants to the island, and now must take responsibility for controlling them.Christmas Island, like many other isolated communities, has evolved over millions of years in relative peace. However, when faced with new challenges and introduced species, these unique ecosystems can struggle to adapt and survive. In fact, of all the species that have gone extinct in recent years, a staggering 80% have been inhabitants of islands.This video from Planet Earth II explores the tragic battle between the red crabs and the yellow crazy ants, shedding light on the interplay between human actions, invasive species, and the delicate balance of island ecosystems. It serves as a reminder of the consequences of our actions and the responsibility we have to protect and preserve the natural world.
