Comb-jelly (Mnemiopsis leidyi) spreading through the Caspian Sea (invasive species)
Philippe Rekacewicz, UNEP/GRID-Arendal
The comb jelly (Mnemiopsis leidyi) is well adapted to the habitat (salinity, temperature, and food range) and reproduces faster than endemic species. As it eats the same food as them, it has had a drastic effect on their numbers, upsetting the entire food chain. The jelly is an invasive species, brought from North America by ships.
