According to scientists, this “invasion” may be due to the effects of wind and changes in sea temperature. “We are seeing a warming of the sea and the increase in jellyfish may be partly due to this,” Valentina Tirelli, a researcher at the National Institute of Oceanography and Experimental Geophysics, told the newspaper La Repubblica.

“Small temperature fluctuations that are not relevant to us are important for these invertebrates, and whether they start reproducing three weeks or a month earlier is of great importance,” says Tirelli. According to the expert, another cause could be the Bora, a northeasterly wind that often blows strongly over Trieste and the Gulf of Trieste. It can cause water to rise from the depths and carry the jellyfish to the shore.
Jellyfish are unpopular with bathers. In the case of skin burns caused by jellyfish, the wound should be cleaned with sea water – never with fresh water – and cooled with ice. In some people, nettle threads can cause dizziness, nausea, and headaches.
