На острові рождества щороку відбувається велика міграція десятків мільйонів краб

Christmas Island is home to an estimated 40-50 million red crabs. These crustaceans have become famous as a result of their "great migration." Once a year, tens of millions of crabs will leave the forest and migrate towards the ocean, swarming roads, sidewalks, and buildings in the process. The island actually shuts down the roads to protect them while they migrate! Once they arrive at the beach, males and females will then mate, and the females will release eggs into the ocean. 🦀 🌊
