Jellyfish simply go with the flow. They drift on ocean currents, waving their tentacles to draw food to their mouth. It’s an uncluttered life.
And it’s working for them. Jellyfish are multiplying.
This is in part because they do well in regions of the ocean that we humans have rendered inhospitable to fish and other marine animals. From the Sea of Japan to the Black Sea in Europe, jellies today are thriving as many other species are being eliminated by overfishing, dead zones and other human impacts.

“It’s time to take jellyfish seriously,” he said.
