Mnemiopsis leidyi was first collected in the Black Sea in 1982 (Zaika V.E. and N.G.Sergeeva. 1990.)

Before the introduction of Mnemiopsis leidyi into the Black Sea, there was only a single species of ctenophore - Pleurobrachia pileus. (Mordukhai-Boltovskoi F.D. Ed., 1969. Determination of the Fauna of the Black and Azov Seas [in Russian]. Volumes 1-3. Kievskaya Knijnaya Fabrika, Kiev, Russia.
