|A warty comb jelly (Mnemiopsis leidyi). The species has numerous other common names.|
|M. leidyi in the Black Sea|
Management of the warty comb jelly is difficult, and may in fact prove to be impossible. However, there has been some success following the introduction of a biological control in the form of a natural predator: another ctenophore (Beroe ovata). Though the introduction was accidental (ironically, through ballast water as well), this new species is though to be the only viable way to control the warty comb jelly.
This is another organism from the 100 World's Worst Invasives list, where it sits at #57.
