The native habitats of the ctenophore, Mnemiopsis, are temperate to subtropical estuaries along the Atlantic coast of North and South America, where it is found in an extremely wide range of environmental conditions (winter low and summer high temperatures of 2 and 32 °C, respectively, and salinities of <2–38). In the early 1980s, it was accidentally introduced to the Black Sea, where it flourished and expanded into the Azov, Marmara, Mediterranean and Caspian Seas. We compile data showing that… 

Transitions of Mnemiopsis leidyi (Ctenophora: Lobata) from a native to an exotic species: a review

The foundations of the ctenophore’s invasive success, which include the source-sink dynamics that characterize Mnemiopsis populations in temperate coastal waters, are reviewed, and the variables most likely to determine whether introduction of Mnemiops to a novel community results in an inconspicuous addition or a disruptive invasion are reviewed.

Aggregations of the invasive ctenophore Mnemiopsis leidyi in a hypersaline environment, the Mar Menor lagoon (NW Mediterranean)

The ctenophore Mnemiopsis leidyi, a species native to estuaries and coastal regions of the western Atlantic Ocean, was first introduced into the Black Sea in the early 1980s and is of great concern given its negative impacts in previously invaded habitats.

Distribution and biology of Mnemiopsis leidyi in the Northern Aegean Sea, and comparison with the indigenous Bolinopsis vitrea

A regulation of the ctenophore populations in the oligotrophic waters of the Aegean Sea is suggested, possibly due to introduction with ballast water.

Shifting abundance of the ctenophore Mnemiopsis leidyi and the implications for larval bivalve mortality

Application of daily ingestion rates to zooplankton abundance indicates that, at its highest densities M. leidyi can remove an overall average of 20–89% per day of bivalve veligers and other zoopLankton taxa, including adult copepods, nauplii, and tintinnids.

Blooms of the invasive ctenophore, Mnemiopsis leidyi, span the Mediterranean Sea in 2009

It is concluded that the spread of M. leidyi in the Mediterranean probably resulted from re-introductions by ballast water transport and subsequent distribution by currents, and the near-simultaneous blooms in opposite ends of both the Mediterranean basins indicate that M. Leidyi is resident around the Mediterranean.

Distribution of the alien ctenophore Mnemiopsisleidyi in the Caspian Sea in August 2001

In this study, spatial and vertical distributions of the invasive ctenophore Mnemiopsisleidyi in the Caspian Sea were evaluated by using data collected at 41 stations during the August 2001 cruise, revealing that M. leidyi were generally confined to surface waters.

Understanding winter distribution and transport pathways of the invasive ctenophore Mnemiopsis leidyi in the North Sea: coupling habitat and dispersal modelling approaches

This study provides the first estimates of the overwinter areas of this invasive species over the cold winters in the North Sea and concludes that M. leidyi has become established along south-eastern coasts of the North sea where the environment conditions allows overwintering and it can be retained for later blooms.

Aquatic invasions in the Black, Caspian, and Mediterranean seas: the ctenophores Mnemiopsis leidyi and Beroe in the Ponto-Caspian and other aquatic invasions

Support for the position that a deliberate introduction of Beroe cf ovata to the Caspian Sea will control the local population of Mnemiopsis leidyi is found, and range extensions of Ponto-Caspian aquatic invertebrates in Continental Europe are studied.



Distribution and abundance of ctenophores and their zooplankton food in the Black Sea. II. Mnemiopsis leidyi

Smaller M. leidyi (1.5 to 2 cm) were present in the winter, and individuals reached maximum size in the summer, and microscopic analysis of stomach contents showed that copepods and molluscs form their main diet.

Invasion of the Black Sea by the ctenophore Mnemiopsis leidyi and recent changes in pelagic community structure

There has been an increase in abundance and diversity of fish eggs, fish larvae, and zooplankton, which together with an increased catch of planktivorous fish indicates that there has been a recovery of the ecosystem.

Mnemiopsis Leidyi Abundance in the Black Sea and Its Impact on the Pelagic Community

This study is an attempt to give a short synthesis of the present knowledge of the development of the ctenophore Mnemiopsis leidyi invader in the Black Sea and a brief review in other seas of the

Timing and size of blooms of the ctenophore Mnemiopsis leidyi in relation to temperature in Narragansett Bay, RI

The ctenophore Mnemiopsis leidyi is at the northern extreme of its geographic range in Narragansett Bay, an estuary on the northeast coast of the United States. Blooms have typically been observed in


Evidence is presented which indicates that all three of these forms are casual visitors to the inland coastal waterways of New Jersey, and the three ctenophores are shown to be able to withstand salinities in the bays which are considerably below those of the ocean lanes from which the animals came.

Notes on the biology of the sea nettle, Chrysaora quinquecirrha , in Chesapeake Bay

The growth of medusae was rapid, and their feeding appeared opportunistic and frequent, and the geographic range of the polyp stage in Chesapeake Bay is partially delineated with respect to depth and salinity.
