Jellicent, as well as its pre-evolution, also seem to draw heavy inspiration from Nurarihyon, a jellyfish yōkai that is either shown as a demonized jellyfish or as a jellyfish-like man who wears refined, sometimes regal, clothing. It is also possible that they were inspired by the Kurage no Hinotama, a sort of jellyfish-like will-o'-the-wisp.

Summary: Royal Ontario Museum announces the oldest swimming jellyfish in the fossil record with the newly named Burgessomedusa phasmiformis ...Conclusions and Perspectives. Jellyfish regeneration involves a combination of cellular processes underlying wound healing, blastema formation, and systemic patterning that require organ or body-level communications. The evolutionally conserved wound closure mechanisms necessitate epithelial tissue repair upon injury.The discovery of Burgessomedusa gives us a new baseline for calculating the timeline of jellyfish evolution. And it drives home the diversity of Cambrian marine ecosystems, which have the appearance of domination by hard-shelled creatures, as those are more readily preserved as fossils. Instead, they would have been rich and complex, with a ...Like other types of jellyfish, the T. dohrnii goes through a two-part life cycle, living on the sea floor during an asexual phase, where its chief role is to stay alive during times of food scarcity.

Because Anthozoa and Medusozoa are sister groups, two alternative evolutionary scenarios are possible: the jellyfish stage is a medusozoan-specific novelty or the jellyfish stage has been lost...Jellyfish Evolution and Species Jellyfish have a long and fascinating evolutionary history.
