A barrel jellyfish (Rhizostoma pulmo), one of the most common jellyfish species in our coast.
Because of the rising temperature of the Mediterranean sea resulting of global warming, every time there are more jellyfish. In the last 3 years, the number of jellyfish in our coast has reached an all-time high. Because of the higher water temperature, jellyfish reproduce more, more species go to the northern parts of the sea, and they approach the coast for many months when they used to only do so for 2 weeks to 2 months. Overfishing has also increased the number of jellyfish, because it has decreased the population of many of its natural predators such as sea turtles.
