Istanbul is witnessing a rise in the number of jellyfish on its shores, especially in the Bosphorus Strait, which connects the Aegean Sea to the Marmara Sea, due to strong winds drawing ocean currents.
"There is a high concentration of jellyfish off Arnavutköy and Sarayburnu," said Melek İşinibilir Okyar, an academic from Istanbul University.
Local fish population has been declining in the Mediterranean Sea, while tropical species migrating from the Suez Canal and the Indian Ocean have been on the rise, according to a Turkish marine scientist.
The migration continues rapidly, and global warming is one of the reasons triggering the migration movements, said Mehmet Gökoğlu from Akdeniz University.
Highly venomous jellyfish have stung more than 3,000 people on Australia's northeastern shores in just a few days, authorities said Jan. 7, forcing the closure of several beaches.
Jellyfish and other sea life were spotted inside a historic mosque in Istanbul after recent heavy rain caused flash flooding, Doğan News Agency reported on March 7.
