Mnemiopsis is a carnivore that consumes zooplankton including crustaceans,[3] other comb jellies, and eggs and larvae of fish. In 1982, it was discovered in the Black Sea, where it was transported by ballast water. [17] The position of Ctenophora and Porifera is currently being actively debated.[18][19].
