True I just wanted to mention these fascinating creatures because they are the closest we have to revival from death.

they can reproduce (they expel gas clouds on death that can eventually create new stars)

I wouldn’t consider being eaten by a pregnant predator who then gives birth to be a form of reproduction even if I supplied resources to the born creature.

they can grow and change size over their lifespan

So can oceans but I don’t think it should count as growing.

I’m not aware of anything already considered living that will die and reanimate.

Tardigrades? They can cease any metabolic activity and then wake up years later as if nothing happened.

Ironic, considering the name

In my experience, the best way to ask about unpopular (here, on Lemmy) stuff is to make a post in a generic community. Discoverability sucks here and not many people are on here too so niche communities are often deserted.

So, if you make a post on popular lemmies like this one, you have better chances to receive a helpful response. I’m not sure how the situation with writing communities is, maybe they are active enough to be of use for you!
