There is a species of jellyfish which is functionally immortal. When they get too old they simply turn into children again and re-age.
Edit: I’m not saying it’s not biologically immortal, I’m saying functionally immortal because I’m indicating that it can still be killed.
Saying something doesn’t experience aging is not the same as insisting it cannot die.
2+2=4 is not less correct because 2x2 also equals 4.
functionally immortal
Biologically immortal is the term you were looking for
No, I meant functionally. As in practically. For all intents and purposes. As in under normal conditions.
It’s like if I said “You meant ‘searching for’ and not ‘looking for’”, when looking indicates visual searching.
In other words it’s a meaningless distinction in the usage and I would look like a real dickhead pedant if I insisted you use another word.
No, it’s “biologically.”
No, my point with “functionally” is that it can be killed.
Biological immortality is a very specific concept indicating an absence of aging and the absence of an increase in expected mortality along with age.
I just mean that something can still eat it. This is an easy concept to understand if you’re not focused on correcting people needlessly.
Biological immortality is the term for what you were describing. The fact that I politely pointed it out and linked a relevant Wikipedia article of the topic doesn’t warrant you to get insulted and call me a dickhead
There is a functional difference between being pedantic about the word “functionally” and supplying relevant information.
My comment indicates that the animal can still die, your comment indicates it doesn’t age.
Do you see the meaningless distinction?

Jellyfish are cnidarians, a phylum which also includes corals and sea anemones. Jellyfish are a specific lifecycle stage of medusozoans (their own subphylum), while corals and sea anemones are anthozoans (another subphylum of Cnidaria).
So yup, they are polyps before sexual maturity. And you’ll find they’re more closely related to corals than they are to members of any other phylum.
Edit: I highly recommend that anyone who wants to get lost in the world of marine invertebrates check out WoRMS and then follow along in parallel on Wikipedia as you navigate the tree.
You just made up all those words.
This graphic is going counterclockwise and I didn’t enjoy that. On the other hand, neat.
