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.

Sort of like humans, but we turn into children again and die. Can't say we don't try tho.

functionally immortal

Biologically immortal is the term you were looking for

I came here to say this... that shit is insane.

Then they'll be unfunctionally immortal.

They will be aerodynamically immortal.

[–] Amanduh@lemm.ee 2 points 1 day ago (1 children)
[–] fsxylo@sh.itjust.works 3 points 1 day ago (1 children)

Then they will be comfortably immortal.

What if they are fans of Evanescence?

[–] fsxylo@sh.itjust.works 1 points 17 hours ago

Then they're My Immortal.

[–] NoSpiritAnimal@lemmy.world 2 points 1 day ago

This is what I mean by functionally.

The proud moment in every jellyfish's life when the buds come in.

[–] TheTechnician27@lemmy.world 122 points 2 days ago* (last edited 2 days ago) (1 children)

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.

Not all words are accepted by society

[–] conartistpanda@lemmy.world 1 points 23 hours ago

Hi, society here. I accept those words.

[–] jaggedrobotpubes@lemmy.world 20 points 2 days ago

Jellyfish are a subcagetorum of cthulonic phteven

[–] Klear@sh.itjust.works 11 points 2 days ago

You neved heard phylum before? You phylustine!

[–] Pothetato@lemmy.world 53 points 2 days ago (3 children)

This graphic is going counterclockwise and I didn't enjoy that. On the other hand, neat.

[–] pyre@lemmy.world 17 points 2 days ago (1 children)

I disagree, time should flow left to right and by the nature of the egg it starts with top-to-bottom. so you have to start on the left, go to the bottom, keep going right, then the jellyfish rises so go back to top and then complete the circle

[–] Redfox8@mander.xyz 5 points 2 days ago (3 children)

But what came first? The jellyfish or the egg??!!

[–] Tattorack@lemmy.world 5 points 2 days ago

The answer is always the egg.

[–] prole@lemmy.blahaj.zone 4 points 2 days ago

Always the egg.

Do you think jellyfish grow in trees?

[–] mc900ftJesus@lemy.lol 29 points 2 days ago (1 children)

Ahh immortality, I’m jelly.

Do you think you just fell out of the jellyfish tree?

They also track sunlight so you can predict where they will be at certain times in areas with shade. Example: more likely to be closer to eastern shores in the mornings, further out at night.

In stasis, it bends but won't break us
Aurelia, majestic as a lion's roar embodies her
Terranean, threaten and shield us
Endanger, recoil and rewind the tapes
She's born again
[...]
Medusa, a haunting allure
Elusive ectoplasmic residue
She'll dance for you
Inducing hydro-cosmic dreams in you
Of eternal blue

I've never read this, and I don't know if it's even a song or a poem or what... and yet somehow, I get the feeling that they're lyrics to a TOOL song.

[–] Entropywins@lemmy.world 5 points 2 days ago (1 children)

Haken - sempiternal beings I had to look it up cause I was 100% with you on thinking TOOL.

[–] prole@lemmy.blahaj.zone 1 points 1 day ago* (last edited 1 day ago)

It's very Maynard-coded

[–] AmosBurton_ThatGuy@lemmy.ca 8 points 2 days ago (3 children)

Jellyfish are creepy and gross, they're like living sea mushrooms.

[–] Agent641@lemmy.world 23 points 2 days ago (4 children)

Mushrooms are creepy and gross too, when you get to know them.

[–] Swedneck@discuss.tchncs.de 10 points 2 days ago (3 children)

fungi are conceptually lovecraftian horrors but in practice they're basically just strange plants, and i find that neat.
