Summer is the season of outdoor activities, long hours spent on the beach and in the water... a wonderful life, which, however, may hide some dangers.
When we bathe in the sea, jellyfish become our summer enemy, because accidental contact with their tentacles will cause pain, itching, and burning.
The presence of jellyfish in the sea seems to be increasing by the day. This phenomenon appears to be the consequence of the depopulation of the Mediterranean Sea and the increase in sea water temperature, as well as overfishing. Fish are indeed the main predators of jellyfish.
