Invazie de meduze uriașe în Marea Neagră / Fenomen natural ce marchează finalul verii

Giant jellyfish appear in the Black Sea during late summer, but they pose no danger to swimmers. Biologists state that while they may cause mild skin irritation, they are not toxic. The species identified is Rhizostoma pulmo, commonly found in warm waters. Their presence is linked to high water temperatures and strong currents that bring them closer to shore.
