More than 50 million red crabs migrate in Australia. What happened? From the end of 10 to the beginning of 10 every year, it is the rainy season of Christmas Island in Australia and the best time for red crabs to migrate. At this time of year, thousands of red crabs run from the rainforest plateau to the beaches of the Indian Ocean, and the migration distance exceeds 10 km. At this time, on the highway near the coast, you can always see the mighty army of red crabs, and the scene is very spectacular.
During the migration of more than ten kilometers, they often have to go through many hardships. They will die from lack of and extreme sunlight, and some will be run over by passing cars when passing through roads or tracks. It is understood that about 6.5438 million red crabs are run over by cars every year during migration. In response, the local government has formulated a series of measures to protect the migrating red crabs, such as closing roads and setting up red crab spots. Dedicated channel? To reduce the casualties of red crabs. In addition, there is a clear stipulation in Australia that fish, shrimps and crabs in inland rivers cannot be caught. This series aims to protect red crab species and reduce their innocent deaths caused by migration or man-made.
Why do these red crabs have to act together? The red crab living on Christmas Island is actually a terrestrial crab. Adult individuals may drown if they receive too much water, so they usually live mainly in the forests on the island. Red crabs will dig their own caves one by one, which can prevent the direct sunlight from causing excessive temperature, otherwise the red crabs will die because of excessive water loss. In order to avoid the scorching sun, red crabs often leave their nests at night and start foraging. On weekdays, red crabs live in a narrow range and hardly leave their nests. But in 10- 12, what will the adult red crab be? Genes? Drive to the sea, mate with the opposite sex, and lay eggs. From home to the seaside, it takes an average of 7 days for each red crab, which is one of the highest mortality stages. Of course, in order to protect the red crabs, the residents on the island will close the road or open the road for them to migrate during the migration.
