Why are jellyfish washed ashore?

it is generally a sign of change. The temperature and pressure on the seabed are rising, and the marine pollution is serious. The recent warm weather and global warming have enabled plankton, the main food source of jellyfish, to thrive. With more food, jellyfish will naturally increase. Moreover, jellyfish can't swim. They drift passively and are carried by ocean currents. When stormy weather comes, they will be washed ashore by the Gulf Stream. And as long as the intensity of tides and waves increases slightly, these jellyfish will be difficult to fight.
