A huge accumulation of jellyfish in the Mediterranean Sea occupied not only a large area on the surface, but also went hundreds of meters deep .
Israeli scientists using drones were able to capture thousands of nomadic jellyfish in the Haifa Bay. These “white dots” occupy a vast territory of the sea and go deep into several hundred meters. Scientists believe that such a large concentration of jellyfish in the area is due to human activities, as well as climate change, according to Live Science.
Nomad jellyfish are currently the most common species of jellyfish in the waters near the city of Haifa, Israel. These jellyfish are an invasive species in this region of the Mediterranean Sea, as their main habitat is the Indian and Pacific Oceans.
By the way, as Focus already wrote, Polish scientists called cats invasive view for Europe and explained why they think so.
Scientists believe nomadic jellyfish entered the Mediterranean through the Suez Canal in Egypt. A surge in the number of jellyfish off the coast of Israel could be disastrous for the local ecosystem and could also affect tourism. This is due to the fact that people are afraid to relax and swim where they can be bitten by jellyfish.
Such a high concentration of these sea creatures in one place is called a “bloom” of jellyfish. And scientists believe that human activity, as well as climate change, played a negative role in this process.
One of the possible reasons for the “bloom” of jellyfish is the pollution of the ocean with waste, from which the jellyfish are trying to escape. Also, the cause may be overfishing and a decrease in the population of marine animals, which are either competitors with jellyfish in the food chain, or they prey on these jellyfish.
“Due to the fact that in recent years the number of jellyfish has increased dramatically in coastal waters, everyone suffers. Both the ecosystem and tourism, and this causes economic damage,” says environmentalist Ruti Yahel.
Environmentalist Dror Enzhel believes that climate change is also affecting the increase in the number of jellyfish off the coast of Israel .
“Last winter was very rainy and at times cold. This may have affected the intensity of flowering and the life cycle of jellyfish. If it rains a lot of nutrients are concentrated in the sea. So there is more algae, plankton and, accordingly, more food for jellyfish,” says Angel.
As Focus already wrote, scientists have discovered an amazing sea creature in the Pacific Ocean that somewhat resembles a jellyfish. This creature has tentacles, as well as a long thin body in the form of a stem.
We remind you that scientists have learned to read the thoughts of jellyfish by placing their nervous system under a microscope.
