A species of poisonous Mediterranean jellyfish has appeared in the Black Sea as a result of the global warming.

This was announced Friday in Bulgaria’s Black Sea city of Varna by Vangelis Papatanasiu, a coordinator of the European project SESAME, as cited by BGNES.

Under the SESAME project European scientists receive funding for researching the changes in the eco-systems of the Mediterranean and the Black Sea over the last 50 years, and to come up with solutions for their preservations. A total of 68 scientific institutes from 23 states are involved.

The poisonous jellyfish species in question has already spread along the Turkish Black Sea coast. The scientists are unable to predict if and when it might populate the Bulgarian Black Sea coast. They have also discovered that a typical Black Sea jellyfish species has also spread to the Mediterranean.

“Even though the two seas are very different, there are already similarities between them,” said Snezhana Momcheva, who is the coordinator of the project in Bulgaria.

In her words, thanks to the global warming, the Black Sea is becoming more like the Mediterranean, which in turn is becoming more like the tropical seas.

The scientists said there was already a tropic fish species in the Mediterranean which became toxic after reaching a body length of 10cm.
