How can an immortal jellyfish, "Turritopsis Dohrnii" help to extend human life?
Bacteria are immortal. The reason for that is bacteria transfer their DNA to their descendants. And that means bacteria are full copies of their parent cells. Immortality in higher animals than single-cell bacteria is not a very usual thing. But there is one biologically immortal jellyfish.
"Turritopsis Dohrnii" is a small, biologically immortal jellyfish. This small jellyfish has a great role in the research of aging. That jellyfish can take back its polyps form. And some insects have the same ability. During that process "Turritopsis Dohrnii" removes things like zombie cells from its body. Removing zombie cells from the body helps slow aging and denies cancer.
" If the T. Dohrnii jellyfish is exposed to environmental stress, physical assault, or is sick or old, it can revert to the polyp stage, forming a new polyp colony It does this through the cell development process of transdifferentiation, which alters the differentiated state of the cells and transforms them into new types of cells." (Wikipedia/Turritopsis dohrnii)
"Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although in practice individuals can still die. In nature, most Turritopsis Dohrnii are likely to succumb to predation or disease in the medusa stage without reverting to the polyp form. (Wikipedia/Turritopsis dohrnii).

Lifecycle of "Turritopsis Dohrnii" (https://www.scienceabc.com/Why Is Turritopsis Dohrnii Called The Immortal Jellyfish?)
The question is, what denies the DNA damage in that jellyfish? Immortality requires that the DNA will not damaged. And taking the polyp form back doesn't fix the DNA in that jellyfish.
There is a process that makes Turritopsis Dohrnii able to keep its DNA in the condition that the jellyfish doesn't age as other animals. Things that normally cause DNA destruction are chemical and radiological stress that makes DNA oscillate, and that means the descendant cells will not get the same DNA as their parent cells. And only just-born human has complete DNA.
The thing is that seawater protects sea animals from radioactive radiation like the sun's UV radiation. The problem is that Turritopsis Dohrnii is not the only animal that lives in seas. Other animals are aging. But the thing that makes this jellyfish interesting is that it's translucent.
That means the structure of that animal doesn't absorb UV radiation more or less than other jellyfish that are mortal. The mechanism that keeps the DNA young is the thing that makes this jellyfish interesting. That mechanism can someday make it possible. That the human DNA will not turn older or be damaged.
The process means that this jellyfish can create new cells. There is always the same DNA. The problem in human aging is that the human DNA is damaging. And if there is something that denies the damages in DNA that thing can open a new chapter in human history. There is a possibility that Turritopsis Dohrnii jellyfish has the DNA that is inside some kind of capsule that denies damage in that molecule. The thing is how this jellyfish denies DNA damage is interesting. And if we want to make humans immortal we must secure the DNA. And deny its damages in all situations.
