This Worm's Gut Has No Way In or Out
Вставка
- Опубліковано 6 бер 2020
- There are plenty of creatures out there with only one opening to handle both taking in food and getting rid of waste. But there’s at least one animal out there that doesn’t have a gut opening… at all. How does that even work?!

"A giant mouthless, buttless worm" sounds like a Cards Against Humanity answer.
procrastinator99 yea it does
Or rather "a worm with a butt on both ends"
Or a Joking Hazard (the card game based on the _Cyanide & Happiness_ comic strip).
"Buttless Worms" I knew before I clicked it was Hank presenting it.
I was ready to be a bit disappointed if he hadn't!! 😄
U got that right.
Only Hank handles these weird ones
You could have thought those were plants. No eyes, no mouth, but plenty of blood nontheless: the colour didn't lie. Under the ocean we found a dreadful garden made of flesh and poison.
Welcome... to Nightvale.
Ah yes, the good ol' mouthless, buttless, bacteria filled, bloody, deep sea tube boys
The tubiest of boys.
tube worms: 11/10. best in show🧡
TUBE BOIIII GANG GANG
😍😍😍
.
Forget the worm. Can you imagine being the guy who landed a sub on top of these things? "Uh, sir. There's blood gushing everywhere. I can explain."
omegasavant Actually no, at that point they couldn’t explain yet, so it’s even more awkward.
:O
ALVIIIIN!!
"Blood. An ocean of blood. I wondered how many blood drops of blood there are in this blood ocean. I wondered how much is in... in a drop. I wondered, how I - let's just say there are possibly..." -- _Metalocalypse,_ s1e19
I remember when this discovery was made, when we saw the films... it was beautiful and triggered such curiosity in me...
"I have no mouth, and I must scream."
"I wake to horror from a dream."
*Francois Lacombe:* Well played.
"I have no butt, and I must fart"
@@VvissiaA: That definitely sounds like an *LGR* (Lazy Game Reviews) reference if ever I've heard one.
^^^ literally my first thought ^^^
"almost looks like a lipstick"... not MY first thought but okay
Willium_Bob_Cole “almost looks like a dog’s penis” yeah hank okay hank thanks hank 👍
My first thought was a cigarette.
I was looking for this comment lol
@@AuntBibby yeah same
Honestly I think they kinda look like the snake from Beetlejuice
That's actually really interesting. It brings up a question... how large can a creature become and still work like this worm? From what I understand these worms aren't exactly small. Could there be MASSIVE creatures on other planets that like this worm only exist because of the bacteria inside of it?
The possibility of extraterrestrial life that works via some form of chemistry (up to and including non-carbon-based life) that is outside the norm is a major point of interest for exo- and xenobiologists. The discovery of these guys and other organisms, both micro and macro, were some of the first hard evidence that maybe things could evolve, live, and thrive outside of the cycles we think of.
@@scaper8
And a funky thought is that these hydrothermal worms are still animals, meaning that they are actually quite close to us on the tree of life (relatively speaking).
We probably share approximately 70+% of our DNA with these worms, just imagine how weird alien life could be!
There might be some likeness between earh life and alien life, because physics applies equally on everything, but one of the challenges with picturing alien life is that it might be too weird for us to imagine, given our limited reference frame!
well actually i was wondering if the worms simply exist as a place for the bacteria to live instead of them being "worms with bacteria inside".
No, there will be a size limit to the organism with this kind of functionality. Because, the amount of resources that the worm needs is proportional to it's volume. So if you increase the size of the worm by 3 times then the the amount of resources it will need will increase by 27 times. The resource requirements will change like the cube of the scale. But, the resource intake occurs at the surface of the worm, which will change as the square of the length scale. So the (resource intake/resource requirement ratio) will be inversely proportional to the length scale of the worm and it will become really small for large sizes. That's why we have multicellular organisms instead of giant cells.
The problem with these sorts of lifeforms is that there had to be a lifeform that came from less hostile environment and adapted to the new habitat. Need somewhere stable, like the ocean, to play around with chemicals to get the concept of life started while not at risk.
when your bacterial infection keeps you alive, say no to antibiotics.
Time for yogurt
People: Live fast, eat ass!
Tube worms: :(
Hahahaha!!!
well, at least they got 1 out of 4!
To the bacteria in the worm's gut: You may ask yourself, how did I get here?
This should be a kid's pop up book. "Hey, let's go explore the deep ocean vents with Mr. Lovecraft. "
So Alvin's crew saw a vent and decided to set down and just immediately crushed a colony of these worms. That's both sad and hilarious because I cannot imagine the crew's reaction to sitting down and suddenly being covered in blood.
If only nautilus had found them instead. Then we'd have video!
Michael: "It's a hole-less donut!"
Or is it really a donut?
Haha
Technically it's topologically neither a donut or a tube with a hole in it. It has a void that has no opening anywhere, but also would be topologically different if this bacterial void didn't exist at all.
What would we call a shape with an internal void or cavity?
A geode? Uh... Well actually I couldn't find an answer (within 4 minutes)z but I did find this which basically says mathematicians specifically topologists might not know or at least they don't agree.
That "this" is here: blogs.scientificamerican.com/roots-of-unity/what-we-talk-about-when-we-talk-about-holes/
The donuthole in the donut actually has a hole of its own!
Ahh, "I have no butt and I must poop," Classic Lovecraftian horror.
Me, horribly depressed, getting the notification for this video: /sigh/ sure tell me about buttless worms, scishow
Oh that's a mood
damn
Big mood.
Why are you depressed?
@@danielboone8256 it's a pointless question, that's not how most depressions work.
My 8th grade teacher tried to tell me I was wrong when I corrected her that not ALL life got it's energy from the sun. She had never heard of tube worms even though supposedly she went to college for biology
Biology is a fast-growing field. What you learn now in high school may not even be existent in textbooks twenty years ago. If it makes your biology teacher feel better, I had a teacher who didn't believe that Greece was (still) a country.
@@herrschmidt5477 The only reason I remembered that was because said teacher made a Greek girl point it out on a world map.
"It's like having.. your kitchen.. in your body.." lol I cracked up so hard with how worried you sounded saying that.
I love Scishow because it always manages to bring cool, down to Earth science without click bait titles or simplifying too much. Love yall
somehow, when i saw the thumbnail 'buttless worms', i knew hank was gonna be the one hosting.
As Jeff Goldblum said in Jurassic Park: "Life will not be contained. Life breaks free and extends to new territories... ... Life.. uh finds a way"
Puts the expression "no if, and or butts" into a whole new level
So this worm actually made convergent evolution into a some kind of plant.
nobody knows for sure but it could just be an offshoot of other tube worms like the christmas tree worm, who use their little feather duster faces to filter out food, only the buttless worms got some bacteria to filter out chemicals and then feed them energy in return rather than just filtering food out directly. Alot of early simple animals do seem alot like plants, sponges even use algea to photosynthesis and sponges act alot like trees with their big "trunks" and all. It's more like tube worms and sponges are an early form of life from when plants and animals first diverged, and they just never really changed too much since simple doesnt always mean worse.
Finally! A SciShow video about not butts.
SciShow video idea brainstorming sessions must be wild...
Hearing what these worms live on reminds me of the Coen brothers' "Raising Arizona," Nick Cage listens as an eldery cell-mate describe his hard-luck childhood: "When there was no fowl, we ate crawdad. And when there no crawdad to be found... we ate sand." Taken aback, Cage asks,"You ate WHAT?" As if sufficient, comes the reply "We ate sand." lol!
This is one of the coolest videos I've seen in a long time!!
YES. BUTTLESS WORMS.
JUST WHAT I WANTED TO SEE ON MY SUB FEED
God , ive hated jellyfish ever since ive been stung and ever since ive tasted them as a seemingly unnatural delicacy , but somehow i appreciate that you have made me hate those stupid fake squids even more .
This goes to prove that we are still learning massive amounts about the world around us and we still have more to learn on a scale that dwarfs us.
(2:26) "It's like having a kitchen in your body." For those who fondly remember the sitcom, _Home Improvement,_ the analogy would be like having a butcher in your refrigerator (the Man's Kitchen from s3e21).
thought the thumbnail just said "butt worms"
🤢 That's a video you won't want to view.
My cat had butt worms
Politicians also get along with having one opening for air in and crap out.
how scared must the ppl in the submarine have been when blood start gushing around them
No one:
Scishow: gut worms!
Butt-less Worms!
Not gut worms... Worm's guts actually
I have no mouth and I must scream.
"Buttholes should only be for entertaining guests" -My brain at 3am when I should be asleep.
Is it safe to assume that this worm also has no legs?
(Because, butt is legs.)
Came here looking for this comment. Not disappointed
Dude, where have you seen ANY worm with legs?
ua-cam.com/video/RHKGWLml_mg/v-deo.html
Tube worms are one of my absolute favorite animals. I first learned about them from the show Blue Planet, and they completely blew my mind.
brb, swallowing the bacteria that they use to make yogurt & cheese so i never have to go to the bathroom ever again
Maybe you should try the yeast they use for liquor.
That way you wouldn't care if you went to the bathroom, or where.
@@lordgarion514 autobrewery syndrome
Insert catchy Butt Is Legs meme joke here
Riftia Pachyptila be like: *I have no butt and I must poop*
i was going to say that. well i was going to say fart
So...they're giant kidneys
Damn nature... you weird!
The strange little parasites that live in the roots of our eyelashes apparently don't have excretory organs, They eat tiny flakes of skin that we shed, but they don't live long enough to need to expel any waste. I think the same is true of some species of butterflies - they don't live long to have to poop.
Exactly the kind of science video that is he willing to watch even if I’m unhappy
Quality video as usual, keep up the good work
Makes you think of the kind of creatures you could see if there is a planet that is just one big hydrothermal vent
This is an amazing video! This captured my interest the moment I read the title! Awesome! Thanks SciShow! You're the best!
As a larvae the tube worms live roughly 38 days while moving using currents and tides. just like plants they shoot out their offspring and hoped it lands near another hydrothermal vent giving it nutrients and food. ( my take on how they move from vent to vent)
Sub lands on a worm...
Operator: "AALLLVIIIINNNN!"
You know the internet has thoroughly ruined you when your first thought is "I bet these have shown up in R34..."
Everyone Poops was a lie? The foundation of my reality is crumbling.
"I have no mouth (or butt) and I must scream (and poop)"
"You giant mouthless buttless worm" is a great insult
I love SciShow, always great videos😍
This has gotta be the weirdest life-on-Earth story yet, and that's saying something.
If butt is legs, do worms with butts actually have legs?
As a wise man once said 'you go little red rocket'
Yay! One more for the butt series!
"buttless worm...not the weirdest thing I've heard today."
Butt how does it fart?!
6+ guttless worms disliked this video.
I love that the first thing humans do in a new habitat is to kill somehthing
When I grow up I want to be a spaceship with no butt.
i learnt new things today; i thank you
OK Google, why am I getting ads for Argentinian laundry detergent?
Another fast fact, one of the researchers that discovered the tube worms, Robert Ballard, would later discover the wreck of the Titanic!
I am a simple man . . . I see a worm without a butt and I click.
And here I thought having a butt-mouth united us. Oh the hubris of the butt-mouth!
Tube worms are a buttless wonder. Who knew?
But, does it have legs?
Well. That's something.
If these worms have no gut inside them, why does my gut have worms inside it.
Inaccurate headline. Butt is legs. Therefore they are not buttless, they are legless.
0:51 So many meat scepters LOL
i think i just had a lovecraftian moment
Yeah, that's awesome, but what do they taste like?
He said the bacteria work by chemosynthesis, but didn't explain how the chemicals get into the worm's gut in the first place.
Feather dusters! My dad used to have these in his aquarium!
basically my brain when trying to receive intelligence
I think most people would think that this fact is sort of meaningless in everyday life but think about all the creationists out there whose argument goes: "How could humans live without a heart, lungs, liver etc?". We didn't, but our ancestors did!
I swear you're stalking me. This is like the fifth time you've uploaded a video on something I've just learned.
Great, now we gotta equip our submarines with flamethrowers, to eradicate every last trace of this thing ever existing.
A worm without abutt? Thats a click
Red rocket Red rocket red rocket
Animals like these that survivin high heat, high pressure, and Sulfur make me wonder if of the two closest planets have we been looking in the wrong place for exobiology. Is it possible that early in the suns life when it was cooler there was life on Venus and as it started to turn into a furnace the life moved to the relatively cool and chemically rich clouds?
No lips, hands, or butts.
In this episode of storage wars...
that is just strange.
Plot twist: *there is no plot twist*
But, is Butt is Legs?
No gut?! Where do they set their beer?
If only we could all be buttless, what a wonderful world it would be...
Yeah... Lipstick.... Thats what it looks like..... 😂
Awesome 😊
Are we gonna ignore that Hank said the worms got absolutely REKT? Let’s bow our heads in a moment of silence. RIP 😭🤣😭
Maybe there's a superior civilization living underneath the earth crust has long been inspecting humans and waiting for us to get matured enough for a peaceful communication without panickedly end up into confrontation.
Maybe they have legs?
So the first thing we did upon first contact is killing them... Yikes.
