A little more than a year ago, while biologist Kei Jokura was in Woods Hole, Mass., he routinely walked down to the water, scanning for comb jellies. "They look like a jellyfish," he says, "but ...

The fusion of comb jellies into a single organism was unexpectedly swift, lead study author Kei Jokura said. Cut jellies' muscular contractions were independent of each other 50 to 60 minutes ...

For one species of comb jelly, survival from injury can come down to numbers.Two Mnemiopsis leidyi– aka the sea walnut–can fuse together and turn into one after an injury. These bioluminescent ...

The comb jelly seemed to have two rare-end lobes and two of a sensory structure called an apical organ, instead of the usual one. Scientists wondered if this unusual individual arose from the ...

In the 1930s, at the very same research station, marine biologist B. R. Coonfield performed experiments on comb jellies that would make Frankenstein author Mary Shelley shudder.

“We know that comb jellies (aka: ctenophores) are sentient in that they can sense their surroundings to find food and change the direction of their swimming if they bump into something,” study ...

Scientists have revealed that the comb jelly Mnemiopsis leidyi, also known as the sea walnut, can undergo reverse development ...

The sea walnut, a type of comb jelly that has become invasive in parts of Europe and Asia, can transform from a sexually mature adult back into its larval form when times are tough.

Scientists have spotted for the first time two deep-sea “jelly” creatures readily turn into one individual following an injury. The study, published in the journal Current Biology, may lead to ...

An Atlantic comb jelly known as the "sea walnut" has the ability to reverse its own aging process, a new study suggests. When food is scarce or the sea creature is injured, the gelatinous ...
