Mnemiopsis (Mnemiopsis leidyi) known as warty comb jelly or sea walnut, originally native to the western Atlantic coastal waters, may not be dangerous to humans but it greatly affects ecosystem of the Adriatic Sea. 

After being spotted in northern part of the Adriatic Sea, mnemiopsis was also seen in Ploče, Dubrovnik Neretva County.

This invasive species is deadly for the fish fund as it feeds with sardines and anchovies, diet of local blue fish. In the Black Sea, the sea walnut caused billion-euro damages.

'The ships probably brought the predator in ballast waters,' Davor Lučić from the Institute for Marine and Costal Research explains.
