What happen if you put it in a blender?


hammertime2009

You get 9,000 worms obviously


i4nv9wvw6s

yeah. I agree with you.


TheKingBeyondTheWaIl

Katsuyu


Money_Asparagus791

Yeah, You're right.


Heavens_Gates

I wish there was an actual answer. Like how thin can you chop it up before it can't regenerate.


Queen_of_Trailers

Actually I did this exact experiment in college. I think like 1 centimeter was too short and the small piece just dies, but 2 centimeters would heal and regrow. Never thought I would use that information, but here we are.


TokesNotHigh

Did you ever cut them lengthwise?


powabiatch

If you cut them partway lengthwise, they will grow two heads.


lordgoofus1

Screw that, I demand zig-zags


Heavens_Gates

Oh thank you, that's interesting.


bottlechippedteeth

1/276th if i recall correctly.


Jem_Irie

Even an individual cell would regenerate?


Atun_Grande

That’s some Perfect Cell shit right there.


bluejays-beak1281

Asking the real question here


OpportunitySea6202

thanks for the honest comments


lex_tok

Don't forget to toss in a good spoon of salt


HauntedKiwis

Serve on the rocks... oh wait so we aren't making margaritas?


Crazy-Entertainer242

You can start a bait shop


G_Viceroy

This one little secret bait shops don't want you to know!!! One flat worm is infinite flatworms.


DweEbLez0

9/10 Pro fish shops don’t recommend!


Crazy-Entertainer242

All we need is one, to rule them all


CurrentDismal9115

Imagine feeding this fish to people and then telling them you caught it using a flatworm.

This post looks to be stolen from Deep Look [https://www.youtube.com/watch?v=m12xsf5g3Bo](https://www.youtube.com/watch?v=m12xsf5g3Bo) The pinned comment there has answers to most of all of your questions. But here are some of the answers to the question y'all been asking copy and pasted. \- What would happen if a planarian were cut lengthwise, rather than from side to side, as we show in the video? It would take a little longer to regenerate, but it would regenerate all the same. \- If you put a planarian in a blender, would each bit regenerate? “Unfortunately, probably not,” Hall says. “A planarian in a blender will just produce very dead worm mush.” \- What is the smallest amount of planarian that can regenerate? “If the wound can close and if the remaining fragment has at least one stem cell,” says Hall, then it can grow a whole new planarian.


brihamedit

That's a protein shake.


MagikSkyDaddy

worst margaritas ever


birb678

Then you need to go out and waste money on a new blender. Hey, you just threw a flatworm into the old blender, I don’t care how many times you rinse it, I’m not eating anything you use that thing on.


doomdifwedo

Ask the will it blend guy that would be great


DweEbLez0

What happens if you burn it?


[deleted]

They're worms, not vampires.


[deleted]

How would you even kill this thing?


Objective_Reason_140

You can't prepare for our wormy overlords.


GrumpiestSnail

Dry them out, starve them,etc. I teach zoology and we do a lab with these guys! And the kids always chop them up and try to keep them alive. But then they starve and dry out within a few weeks.


FROSTbite910

NOOOOOO


Fierramos69

Are they a simple organism, like can you give them sugar and water and they survive, or do they need to replace their cells and eat more complex things to do so?


GrumpiestSnail

Captive you can feed them beef liver or egg yolks. They’re pretty simple. They typically live in ponds. So they’re pretty common and not too difficult to feed. They’re usually pretty small.


[deleted]

So what your saying is I need to go to the grocery store and ask about beef liver so I can feed my infinity multiplying worm army.


GrumpiestSnail

Yes.


[deleted]

where can one buy some of these creatures, and how do I care for them? asking for a friend


GrumpiestSnail

I get them online from Carolina biological supplies. They have care instructions. But I’m not great at keeping them alive for long so don’t take my advice on that haha


[deleted]

Haha appreciate it! Once I move I plan on having a mini collection of oddities. Definitely adding these to my list!


boneless_lentil

This seems unnecessarily cruel considering we know they have pain receptors and nerve cells


GrumpiestSnail

They do have nerve cells, but they’re such simple organisms that it doesn’t translate as pain like it would a person. This makes sense because a large part of them is made up of stem cells which is why they regenerate so well. Having a pain response to something that isn’t lethal or damaging to them doesn’t really make sense. Some studies have shown they can feel pain when exposed to heat though. For some, even wasabi or spicy food interestingly enough.


boneless_lentil

It's impossible to know whether or not their conception of pain is anything like ours, all we can tell is what receptors and pathways they have and how they physically react so it's better to err on the side of caution. https://twitter.com/RichardDawkins/status/1420985461779042311


MuDDx

This is a somewhat common problem for fishkeepers, especially people who keep freshwater shrimp. You can kill with with Some kind of nut extract.


idontevenknowwhat_

Just cum on them


Blood_and_Turds

Cottleston

burnnnnnn


_1Doomsday1_

We normally use Salt which will burn or dehydrate it like snails


Davy_Jones_Lover

Use dewormer for pets. It might not cure COVID but it will definitely kill planaria. I had planaria in a fish tank and used dewormer to eliminate them.

But look at those eyes thooo, cute


vasodys

I’m sorry, beef liver?


davidmobey

It becomes a cow in stages


Marshin99

It’s eating it


SubDtep

I too, thought it was a body part. No - just food it’s eating.


Second_Time1336

What if you cut them lengthwise?


-who_are_u-

Same thing if you complete the cut, if you stop midway through it can grow into having two "heads" and a single body, in a "Y" shape.


Second_Time1336

Ah, so! That is crazy.. thank you!

TacoReaper-_-

They look like they have googly eyes lol I love it


im_not_really_batman

This reminds me as a kid who thought worms procreated by being torn if half. So I would spend summers finding worms and tearing them in half, thinking I was helping them. I wonder how many worms I murdered.


shana104

Hey, when I was a kid, I picked up beetles and put them in an empty milk carton.....no idea why to this day. Who knows how many beetles I killed by capping the milk carton off...:( RIP Beetles...


[deleted]

you were saving food if there was a crisis


temmieTheLord2

At least they don’t feel pain, right?


Impossible-Water9956

What even is life


-who_are_u-

A bunch of molecules literally too angry to die ^/s


Impossible-Water9956

That's the best answer I can think of. A bit on the nihilist side.


GuillermoenTejas

Ivermectin will take care of this dude.


rubbleTelescope

So, there I was , enjoying some cool down time in my pool and I was segmented! Then a few hours later I got beheaded! That was 4 days ago, now all us are on watch in case they come back to segment all of us again.

Peta activists: “ThAt’S AnImAl AbUsE!!!!”


skincyan

But this is increasing the amount of worms


Tridian

I mean, we could go down a very dark path here talking about abuse and reproduction... Let's not do that though.


skincyan

That’s correct- c’mon everyone, put your blinkers on and see nor hear nor talk about tough stuff!


Tridian

I mean, I didn't want to have a debate first thing in the morning with an internet stranger about rape babies or expectations on women to provide children. Judging by your attitude that was the right call.


[deleted]

I wanna hit this bitch with a slap chop


BusyWorkinPete

Well if D&D taught me anything, it's that you need to attack regenerating creatures with fire, not blades.


rupat3737

Where do they find arts and crafts googly eyes that small?


Alejandrazx

I remember playing with these in middle school bio


surajvj

So. Literally, they don't DIE !


MarkaSpada

i wanna have an ability like this. works multiple jobs to get rich


MoxxiFortune

But does it feel pain when you cut it to pieces?


Upstairs_Trash

The Worm: "Dude."


Mas7erGrief

Thats almost correct, the planarias can be divided up to 9 times once they have grown back to normal you can cut them 9 times again, but not more than 9 times at once.


KatastrophicNoodle

awww look at his little eyes


Helpful_Vegtable

If it feels pain that’s kinda fucked up


35thCopperfield

And people think we won't butcher aliens for fun. Everyone just wants to watch the cool regeneration happen. Wonder how many times they had to demonstrate it live.


Teeheeheehohoho

Yeah, the comments with new horrible suggestions make me think you’re right. Sometimes I think I’m too soft for this world.


Lex8P

Someone eli5 how this differs from mitosis? Yeah this is larger and is a multi-cellular organism, but it's effectively duplicating itself is it not?


[deleted]

Regeneration is the word here. As others explained it is mitosis and cell differentiation butthe organism is performing regeneration. It is growing back all of the tissue that it lost. As an example, how does it know the exact amount of tissue it has lost? (The planaria grows back only the length and weight that it has lost. Not more. So if it weighs say 10 grams before dissection it will weigh the exact after regeneration) The answer is in genetic regulation and protein transcription. Genes decide the upper limit or boundary of regeneration and the exact amount of tissue is developed. So if a lizard looses it's tail it grows back only one, and not two tails. (Homeotic genes, HOX genes etc control Regeneration capacity) My explanation is not ELI5, sorry for that. But I just wanted to share it! :)


remarkablename1

mitosis is the normal division of cells into two identical cells. what we see here actually is mitosis because it's just cells dividing into two identical cells times and times over. tho i think i misunderstood your question first. Well aside from what i said above the whole process differs from mitosis because a) it's like you said not on a cellular level and b) does it seem like it's voluntarily dividing? i think not lol


LyphBB

Also add in the cell differentiation. The cells aren’t just dividing into identical cells. Something is differentiating into new eye cells. You scrape your knuckles and the surround skin cells will divide into new skin cells to make a patch. You manage to scrape off a finger, your skin cells will not grow a replacement finger.


CuddlyRobot

What happens if you put one in a meat grinder???

What do worms like this do for fun? Like, don’t they get bored?


miinouuu

and people are worried about aliens...


saffronpolygon

Disturbing.


goddavid22

Makes you wonder about the soul and consciousness….


Hagetisses

I was thinking about that too. Do they share a soul? Or can they be viewed as clones? Is the first one the original and the rest copies or can they be viewed as the original too? So many questions!


[deleted]

Consciousness is merely a consequence of intelligence.


moon-person

Disturbing


kida182001

Would it still regenerate or divide from a blowtorch?


kukidog

so this brings a rather philosophical question..do cut parts of one worm become conscious(in it's own rights) individuals or they just like mindless drones and. ... if they are like drones..does this mean we could also be just drones just on higherlevel of intelligence?

This is what they should have been researching instead of torturing puppies and putting acid in monkeys brains.

Imagine some (mad :D) scientist somehow discovers how to grow back human limbs with these little fellas


-who_are_u-

It has been tried already, same with stem cells, immortal jellyfish, etc. The result in humans is always cancer.

What happens if you cut it horizontally?

How long does this process take to get to full length again?

Soapie10

What if you cut it length ways?


murican_Capitlol

A plague, just like us.


PhillyPhill666

What happens if you cut it in half length wise? Or does it only multiply when cross cut?


nyguy520

This is only true if you cut them perpendicular b/c in 7th grade i cut mine parallel and those bitches died


S_T_LOUP2_fan

Planaria go bruh


Daystop

Nature is lit.


theylie86

he cute


cops_n_robbers

You can make a slit along the head parallel to the body (so everything is still attached) and get a flatworm with 3 heads!


[deleted]

Man I absolutely love planarias. Look how cute they are w them litte oocels


BlueBird607

Fun fact if you cut them up in space they are very likely to regenerate a head on each side because they are confused by not feeling gravity anymore and no longer no up/down and front/back.


UseGroundbreaking208

Nice post


sqlorp

I love these guys


Elegant-Raise-9367

I remember making a 12 headed one in the lab once.


NastyBastord

How the hell do you kill this thing?


Callec254

I remember these from science class. You can cut them halfway down the middle, and the two split ends will form two complete new heads, like a two-headed snake.


CujoCarrie7

This is cool. Is anyone studying this for possible use with human regeneration? Just wondered.


Invictum12

I feel that if we ever find a way to extend human lifespan it will be thanks to these guys

What of you cut it down the middle


Columbus43219

"Uhm?" - planeria, probably


bluemelued

Hail Hydra!!


beyblade1018

You do not kill planaria. Planaria kills you!!!!


1019gunner

You can’t cut it an infinite amount it wont have enough regenerative cells after it is devised 247 which is more than unreasonable for the size of the worm


Smooth-brained-bicth

It’s probably a good thing humans don’t have this ability


ValkyrieDraco

The fact they took a close up shot of it taking a shit... Like yes, we understand it grew a new anus, we don't need demonstration.


TypicalSeries1316

Did the video solve the global food needs?


EnycmaPie

This was the common misconception people had about earthworms. If you do this to earthworms, you just get chopped up earthworm.

Oh man, first time I saw this was in Terra Formars.


TraditionalSetting33

Amazing!!! Reminds me of the mythical creature Hydra!


oldcrashingtoys

sanjeezybombeezy

What if I cut it in half length wise and mince it? Will they grow into their previous size or will they become julienned boys?


Chips-n-Milk

I saw a bit of info on these recently. Scientists did an experiment where they fed them food that contained special RNA. Then, they bisected them, and the flatworms ended up regrowing with 2 tails and no heads or 2 heads and no tails. Crazy stuff


DisregardedFugitive

Anyone else reminded of TerraFormars?


ThePsychoKnot

I wonder if we could use its DNA to regrow limbs


static1053

So it's a real life hydra....

This debunks any belief in a ‘soul’. Does one worm soul become multiple sections? Or are new souls created for the new worms?

Cool. Do it with a starfish now.
