I don't know if I'd want to be a baby again, but I'd settle for the locust thing of dipping out for a 20 year nap and seeing where we're at then.

From memory - The longest scientists have kept an immortal jellyfish alive in captivity is 5 weeks.
Their physiology requires ocean pressure and movement
Turns into a polyp that divides into new individuals, thereby dying in the process.
Wouldn’t this be bad for the species in many ways?, can’t understand the evolutionary pressure to allow this
Yeah, the whole point of classic sex is that it allows for a LOAD more exchange of genetic material than you have with the usual creeping, genetic mutations, compared to lifeforms that self-reproduce.
So there's not an 'evolutionary pressure' here as I understand it, but more like a niche being exploited. We must remember that ~99% of lifeforms on Earth are extinct, and that there are no guarantees of any kind upon sustainable survivability.
For example, with ocean acidification growing pH changes, a range of species (like this one) might suddenly quickly vamoose as a species, with no chance to adapt. That's the 'choice' they made... to live inside a certain niche of sustainability.
Until the lights go out for them... which countless species have experienced before.
Btw, what's that red blob with a cross?
That signifies that the jellyfish is about to do a cleaving attack that you have to dodge. If it were yellow then you would be able to parry or block.
This might help. I don't know anything about this specific species.

if there's any word, prefix, or suffix added to 'immortal', i dont want it. 'biologically immortal', 'functionally immortal', 'spiritually immortal'. if you have to put an extra qualifier in there, meaning it's immortal-ish, then that ain't immortality
