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

[-] NoSpiritAnimal@lemmy.world 56 points 1 day ago* (last edited 5 hours ago)

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.

[-] LovableSidekick@lemmy.world 3 points 17 hours ago* (last edited 17 hours ago)

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

[-] prole 9 points 1 day ago

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

[-] fsxylo@sh.itjust.works 26 points 1 day ago

Then they'll be unfunctionally immortal.

They will be aerodynamically immortal.

[-] Amanduh@lemm.ee 1 points 22 hours ago
[-] fsxylo@sh.itjust.works 2 points 18 hours ago

Then they will be comfortably immortal.

[-] NoSpiritAnimal@lemmy.world 3 points 1 day ago

This is what I mean by functionally.

[-] finitebanjo@lemmy.world 5 points 1 day ago

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.

[-] TheTechnician27@lemmy.world 115 points 1 day ago* (last edited 1 day ago)

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.

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

[-] pyre@lemmy.world 16 points 1 day ago

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 1 day ago

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

[-] prole 4 points 1 day ago

Always the egg.

[-] pyre@lemmy.world 1 points 1 day ago

don't listen to the other comments they obviously don't know about the primordial jellyfish

[-] somethingp@lemmy.world 8 points 1 day ago

If you change your orientation, this could still be clockwise

[-] Benjaben@lemmy.world 19 points 1 day ago

Yep if I look at the back of my phone, instead of this, it is indeed!

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

[-] Agent641@lemmy.world 23 points 1 day ago

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

[-] Swedneck@discuss.tchncs.de 9 points 1 day ago

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

[-] nomous@lemmy.world 3 points 1 day ago

they're basically just strange plants

Actually they're closer to strange animals, which just reinforces just how neat they are!

[-] Swedneck@discuss.tchncs.de 2 points 1 day ago* (last edited 1 day ago)

i know.
The dichotomy is between the knowledge that they're closer to animals than anything else, yet they don't behave anything like animals and they permeate basically every part of the earth.

[-] nomous@lemmy.world 2 points 1 day ago

Permeate basically every part of the earth.

And perhaps beyond!

[-] AmosBurton_ThatGuy@lemmy.ca 4 points 1 day ago

I hate mushrooms with a passion tbh, not just the way they taste, but even seeing them growing in the wild grosses me out. Disgusting things, I'd eat bugs before resorting to eating mushrooms.

[-] meowMix2525@lemm.ee 12 points 1 day ago

Hard disagree on all points.

[-] PlexSheep@infosec.pub 6 points 1 day ago

They are creepy and I don't like the taste too, but just know that they are an important part of nature for reasons someone else can explain better

[-] jaggedrobotpubes@lemmy.world 6 points 1 day ago

Nooo they're so cool. I could watch them all day.

[-] AmosBurton_ThatGuy@lemmy.ca 3 points 1 day ago

Fair enough, they just creep me out for some reason lol.

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

[-] prole 3 points 1 day ago

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 4 points 1 day ago

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

[-] prole 1 points 7 hours ago* (last edited 7 hours ago)

It's very Maynard-coded

[-] marcos@lemmy.world 7 points 1 day ago

Well, it's wild, but there's not a lot of fuck in it.

[-] Annoyed_Crabby@monyet.cc 3 points 1 day ago

Kinda fit, they have no fuck to give too.

[-] subtext@lemmy.world 5 points 1 day ago

I don’t believe any single part of this, it just can’t be true

[-] Swedneck@discuss.tchncs.de 8 points 1 day ago

the more you learn about how different species work the more your current worldview absolutely crumbles into dust and you see reality for the lawless mess that it is.

Barnacles are crustaceans, if you slice one in half you see that it's a fucked up deformed crayfish sitting inside the shell.

One species is immortal, and just does this cycle again when it gets old.
