Injury-induced fusion leads to the formation of a singular organism among these peculiar marine creatures.
Time doesn't always mend all hurts. If you're an injured comb jellyfish, like the unusual species known as Mnemiopsis leidyi, or the warty comb jelly, you might just need a buddy of its kind to merge with. That's what researchers at the University of Chicago's Marine Biological Laboratory discovered.
These jellyfish, native to the western Atlantic, possess a bizarre ability to fuse together after suffering injuries, merging not only their outer tissues but also their nervous and digestive systems. The fascinating findings could spearhead significant advancements in human regeneration research.
The breakthrough was inspired by an unexpected observation. A day after collecting some comb jellyfish from the wild, the scientists noticed an unusual one. This particular specimen had two apical organs, a sensory organ commonly found in many invertebrates, instead of the usual one. It also had two aboral ends, meaning it had two butts – an oddity indeed.

The researchers hypothesized that the jellyfish had previously fused together as a means to survive injuries. To confirm their theory, they experimented by partially amputating lobes from other jellyfish and placing them together in a tank. As reported in Current Biology, in nine out of ten cases, the pairs of comb jellyfish combined into a single entity. The merged jellyfish survived for three full weeks in their holding tanks.
The fusion process was a rapid one. After just an hour, the movement of the grafted lobes became synchronized. One hour later, the overall movement of the combined creature's lobes were 95% synchronized. By the following night, the boundary between the combined jellyfish had become "continuous," with the outermost layers of tissue appearing "seamless." Even the nervous systems showed signs of joining forces. Poking a lobe on what had been one jellyfish caused a startled response in a lobe that belonged to the other.

The digestive system of the fused jellyfish worked as a united front. One side of a fused jellyfish, for example, could be seen digesting a brine shrimp that had been injected with a fluorescent substance. As the jellyfish began digesting it, fluorescent particles could be seen flowing into the lobe of its attached compatriot, which eventually released waste.
Despite the clear signs of fusion, the actual merging of the jellyfish may not extend to their excretory systems. The two jellyfish didn't poop out waste simultaneously, suggesting they might not truly become a single entity.

The discovery could go beyond describing a strange survival mechanism. Kei Jokura, a postdoctoral researcher who worked on the study, noted that the jellyfish appeared to lack a system for allorecognition – the ability to identify if cells belong to the self or others. Allorecognition is crucial to medical procedures like organ transplants, so understanding this unusual behavior in the jellyfish could pave the way for advancements in immune system and regeneration therapies.
In conclusion, further research is required to explore the impact of fusion on the nervous, digestive, and regenerative systems of injured Mnemiopsis leidyi jellyfish and how their unique survival mechanism might contribute to human medical advancements.
