In Florida, USA, there is a real invasion of crabs. They they even climb walls, which looks scary.
The message about the crustacean crowds appeared in social networks. Users post videos in which you can see a huge number of crawling crabs. Animals are sent through urban quarters to the ocean. They crawl, including into the yards, climb onto walls. Crabs are harmless to humans – they can pinch a maximum with a claw, if they feel threatened. But in such numbers on the streets they interfere, for example, with drivers.
Experts believe that the crab invasion is associated with seasonal by migration. Although it usually occurs in autumn, climate change could provoke an earlier movement of animals.
