Secret Lives of Jellyfish: Robots, Genetics, and World Domination

The rhopoema nomadica, or nomadic jellyfish, is native to the Indian Ocean but in the eighties, they started turning up in the eastern Mediterranean, presumably through the Suez Canal. Now this jellyfish forms massive plumes, kilometers wide, along the coast of the eastern Mediterranean and Israel. For the first time, recently, a huge plume formed off Egypt's coast, and off Turkey and Lebanon. When it blooms intensely, it can get sucked into the watering systems that power plants use to cool machinery. Jellyfish are gooey, like a sink stopper, and clog the intake systems, so they have to shut down power plants until they can clear the bloom away.
