What is the collective suicide of "sail jellyfish"?

For weeks in April last year, thousands of mysterious floating objects appeared on the beaches of the West Coast of the United States. Their bodies are transparent, blue-purple umbrella-shaped, and they look slimy. It is estimated that the total number of plankton is more than a billion, and they are densely packed on the beach, most of which are dead and the rest are dying.

What are these mysterious planktons? Why did they go ashore en masse to commit suicide?

——The Truth——

Caused by increased inshore sea temperatures

After investigation, some experts believe that the reason for the collective suicide of "sail jellyfish" is the rise in the temperature of the coastal sea.

When the temperature of the nearby sea rises, the warm "sail jellyfish" will come from the surface of the deep sea, they take their wives and children, call on their grandfathers and mothers, and happily gather in the coastal seas to forage for food. To their surprise, the wind direction suddenly changed.

In general, the temperature in the offshore area in early spring is lower than on the surface of the sea, and the wind generally blows from land to the sea. But in recent times, due to the abnormal increase in offshore temperatures, the wind has taken a one hundred and eighty degree turn at this time - blowing from the ocean to the land. Under the attack of this unexpected wind, the "sail jellyfish" was completely confused, blown around the body, and lost the ability to control the direction.

At sea, they can also sink deep into the seabed to escape the storm, but they cannot escape the wind and waves in the offshore sea, and can only be blown to the beach. Once ashore, their crystal-clear bodies dried up, crumpled into a piece of plastic, and died quickly.

So what is the reason for the sudden increase in inshore water temperature? According to the analysis, this is because under the influence of the global warming environment, the local spring temperature has risen rapidly this year, and the spring cold has rarely occurred; coupled with the rapid recovery of land temperature, the temperature of the river discharged into the coastal water is also higher, which has led to an abnormal increase in the temperature of the coastal water.
