How did jellyfish evolve https://singularityhub.com/2022/03/03/looks-brains-personality-how-will-humans-change-in-the-next-10000-years/ ...It was then that a sort of schism of evolution happened: on one side, the decentralized nervous systems of cnidarians like sea anemones, coral, and jellyfish, and on the other, essentially everything else, with a few exceptions. The lack of a complex centralized brain, however, has not seemed to hinder jellyfish evolutionarily.Jellyfish from Papua3 and Papua15 displayed the oceanic ecotype as defined by Dawson and Hamner (2005) (terminal club length > 0.5 times bell diameter, spots and blue pigmentation). Jellyfish from Papua4 2016–2017 clearly showed the derived ecotype (loss of spots and pigmentation, terminal club length < 0.2 times bell diameter).

The species T. dohrnii was first described by scientists in 1883. It was 100 years later, in the 1980s, that their immortality was accidentally discovered.

Located on their tentacles, jellyfish's stinging cells are called cnidocytes. They are small compartments that house a mini needle-like stinger. When an outside force triggers a stinger, the cell opens, letting ocean water rush in. This causes the stinger to shoot out into what triggered the action; once it’s there, venom is released. published 28 June 2021.
