To test whether this comb jelly was actually two individuals who had fused together, the scientists tested individual ctenophores collected at different sites on separate dates. After cutting off ...

A recent study has revealed the extraordinary capacity for reverse development in the ctenophore, or comb jelly, specifically in the species Mnemiopsis leidyi. Comb jellies seem to use the strategy of ...

Yet a pair of recent studies about comb jellies raise provocative questions about Descartes’ maxim. The first is a study from the journal Current Biology found that ctenophores, a phlyum of ...

Researchers at the University of Bergen in Norway realized they had a de-aging specimen in their lab when they found a larval ctenophore in a tank where a mature comb jellyfish was supposed to be.

Scientists have discovered a marine animal that can reverse its aging process. The comb jelly, a jellyfish-like creature, can revert to a younger state when stressed. This discovery challenges ...

Among them, the 'immortal jellyfish' (Turritopsis dohrnii) has long been recognised for its ability to revert to an earlier stage of life. Now, researchers at the University of Bergen in Norway have ...

Reverse development, where some animals can turn back to earlier life stages instead of aging normally, has now been documented in the Atlantic comb jelly, Mnemiopsis leidyi, often known as the ...

The latest report also mentions another species, Mnemiopsis leidyi, commonly known as the comb jellyfish, which appears to resist ageing. Researchers from Norway’s University of Bergen observed ...
