Scientists have unraveled the biological mechanisms behind what they describe as the extraordinary “superpower” ability of jellyfish to regenerate body parts.
Jellyfish are primitive animals which evolved in the oceans around 600 million years ago. Part of the reason for their evolutionary success is that some species are able to grow back tissue that has been lost—a trait that is rare in the animal kingdom.
To learn more about this poorly understood ability, a team of researchers from Tohoku University in Japan investigated the biology of a jellyfish species known as Cladonema pacificum—which has tentacles that spread out like tree branches—for a study published in the journal PeerJ.
