Description:
North American comb jelly (Mnemiopsis
leidyi) was brought accidentally to the Caspian in
the ballast water of oil tankers. A voracious feeder on
zooplankton and fish larvae, it first arrived in the Black Sea
in the early 1980s where it changed the whole ecosystem
and contributed to the collapse of more than two dozen
major fishing grounds. From there the comb jelly also
invaded the Azov, Marmara and Aegean Seas and most
recently the Caspian.
