- It seems obvious that animals need oxygen to live, but deep in the Mediterranean Sea there is a very small animal that might be doing just fine without any oxygen at all.

Hey scishow! I've heard in some circles that the carbon from "rolling coal" in a diesel truck is too dense and ends up falling back down to the earth before getting into the atmosphere. Could you guys do an episode about that?
Did you know you can type ' ‽ ' and use it instead of '?!' 😀
@@mishinegluposti1466: How? I must know your secrets, oh wise keeper of the interrobang!
@@sdfkjgh I'm not aware of a specific key for PC, but on android you can long press the question mark button, and you get "‽" !
I don't need oxygen, I can quit any time I want.
No Jack Rhyder, we need you
Lol
You could for the rest of your Life
these are just choices
I don't think so. It's very addictive
Theyre *_breathtaking_*
NO YOU ARE BREATHTAKING
Youre all breathtaking!
Oml yyyyyyy 😂😂😂
ALL OF YOU ARE BREATHTAKING
That sketch looks like something out of the Alien universe
If a chemistry student is too stupid to learn about Oxygen,
does that make him an oxymoron?
No it would make him a bad joke. Just like this one :*

"The mitochondria is the powerhouse of the cell!"
Unless they use hydrogenosomes.
I might have said this in another comment section, but it won't hurt to say it again: Olivia, your presentation skills have improved greatly. Thanks for all your hard work!
She gotten way hotter, also.
I am a human biologist and bacteria are also fascinating for my field of research! We have about 3 times more microbial cells than human cells in our body. And they possess important functions but need to be controlled. For example, we are just starting to understand the role of the microbiome in the development of certain diseases. Acne of course can be provoked by bacteria but amazingly we also start to find links between certain bacteria and the development of anxiety disorders or depression. I am planning to make a video about this in the nearer future!
have you ever heard of a product called th-cam.com/video/P-ozTocLaag/w-d-xo.html somehow supposedly using the 3rd form of life known on this planet Archaeota? I may need to go back to college for some refresher courses in general biology though with all the new changes to Scientific nomenclature and such i learned well over 20yrs ago now... ?
Life Lab Learner I got a question, how do scientists make money, like they don’t sell anything
CL Melonshark hmmm,funding by who,the government?, and if so, how much do they get paid
@@firstname4304 In the modern day scientists are usually funded by grants, often from governments or non profits. Many scientists also work for private companies (like medical research for pharmaceutical companies or geological research for mining companies) and are drawing a salary from the company. There are other ways of getting funding but these three cover most of them.
As for pay, it varies significantly depending on industry and whether it is working for a private company, a private lab or within a university. The best paying positions can be well over $100,000 a year, especially in the private sector. In non-profit sector, $40,000-70,000 is a good estimation at most labs. These estimates are within the United States and I can't stress enough that there is a huge range of salaries depending on field, region of the US, how the lab is funded and how long one has been working in the field.
AdmiralPaco oh ok,thank you very much for explaining it,have a good day ser/mam
This is really exciting if you think about the possibility of extraterrestrial life on other planets and moons (think Io, Europa etc). Oxygen is not the only possible way for chemical energy conversion. We kinda knew about this but still super cool to see.
@@hellfire66683 I appreciate the recognition of Io the main problem with Io is it doesn't have "ice" at least anymore it probably did at one point billions of years ago but the extreme internal volcanism has long since volatilized away ices and other light volatile elements/compounds instead the worlds surface is constantly overturning itself in thick basaltic lava flows and pyroclastic outbursts of tidally induced volcanism. Effectively any ices the world once had have long since erupted or sublimated away a process that has probably continued over much of the history of the solar system and continues to this day as sulfur dioxide, sodium and the likes in volcanic plumes escape the moon and are funneled into Jupiter's Van Allen belts and powering the absurd auroral activity that constantly rages the planet. Perhaps if some hypothetical magma dwelling silicate based life could exist on Io but the environment could not support water based life as Io lost its water billions of years ago.
Brainstorm just wait for electrical aliens
@@hellfire66683 I'm with you! Io is an interesting moon to consider. But Io doesn't have any Ice at all (least amount of H20 of any astronomical object in the solar system), Europa has the ice sheets. Cheers
@@rgerber Haha yeah wouldn't that be fun and scary at the same time?
@@hellfire66683 Not far fetched indeed. It could be possible. Might be interesting to see new data over the next decade. But afaik currently IO has no ice.
Humans: We need oxygen
Loriciferans: Hold my oxygen
most comments: THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL
Powerhouse of the eukaryotic cell.
are*
I was about to comment this
Oxygen? We ain't got no oxygen! _We don't need no stinkin’ oxygen!_
I have an oxygen addiction
I tried to quit, but after a few minutes I was feeling blue.
Ok I am leaving
I approve of the dad jokes.
I can see a budding stand up comic Ken
0:45 But, sulfate and nitrate both contain oxygen.
I believe the "need for oxygen" is referred to as O2 gas.
Yeah i doubt the oxygen atom gets split from the molecule. It just shuttles electrons, right?
As shocking as it may sound, the oxygen molecule is a great oxidizer. That's what makes it the most important part of the electron chain that powers the mitochondria, it recieves those electrons to fuse into carbon dioxide. Sulfate and nitrate can't do that, the oxidizing power of their oxygen has been spent bonding to their respective elements.
So there is no oxygen whatsoever? Come on something
The Mitochondria is the pOwEr HoUsE of the cell
Edit: Thx i didnt notice and you were correct. I havent found the way to turn auto correct off.
Well I guess autocorrect nuked that meme reference
Yes but let's take a moment to remember that mitochondria is the powerhouse of the cell
😂👌😂👌😂👌😂👌😂👌😂👌
Hi... *AGAIN*
@@dontwatchmyvideosyouwillre6997 wtf we're like everywhere
Lol
I had a sealed terrarium once that was store in my closet by mistake so all the plants died, it was in there for about 18 months and when I took it out there were still moving insects in there, Definitely not springtails, but some other type of detrivores. Also, for the record, it was sealed with a cork tightly and sealed again with epoxy, I do not think oxygen could have leaked in.
Did you find any tardigrades? They have been found very much alive after being exposed to deep space.
I don't _need_ oxygen either.
I willfully choose to inhale it with every conscious breath, as I voluntarily choose to continue living.
In a truly free society death is a choice
Mitochondria: *Exist*
Anaerobic life forms: I'm gonna end this man's whole career.
Did you know that the mitochondria are the powerhouse of the cell?
Not these ones
Where were you guys a few months back when I was trying to research into this phylum?? 😜
Great video, guys... Appreciated it. 😁👍🏻👍🏻
Animals that don’t breathe oxygen: exist*
Oxygen: am I a joke to you?
Animals that don't breath oxygen: yes.
To be fair it seems Eukaryotes are descended from the newly discovered Asgardarchaeota, anaerobic microbes which seem to have most of the complex machinery and organelles Eukaryotes do except without the mitochondria and bacterial DNA, that billions of years ago managed to engulf an aerobic bacteria and make it work for them allowing them to not only survive the oxygen revolution but thrive. Our cells even retain forms of anoxic resperation used as an emergency back up in the case of absence or deficiency in oxygen it is just in most animals that isn't enough to maintain function and leads to damage. If you have ever run at speed and had that burning in your legs as you become out of breath you have experienced this anaerobic respiration. It hurts because the byproducts are toxic to us.
I just shared this video with a friend of mine who does basic research on mitochondria using CRISPR-CAS9 to knock out genes and see how those organelles react. She is kind of an expert on the functions mitochondria serve other than producing ATP, like how they help cells divide.
0:13 MITOCHONDRIA IS THE POWERHOUSE OF THE CELL!!!
anaerobia: absence of oxygen
anaerobic animals: living things that dont need oxygen
oxygen: " *UHHHHHHHHHH WHAT????* "
Not all the anaerobic living beings are animals, some of them are just single cells
I have studied this and what is happening is that these creatures are able to produce oxygen inside their bodies just like certain fish can produce light and make themselves glow. These organisms produce their own oxygen within them therefore they do not need it outside of them but they still need oxygen to survive
Great video!
Money is like oxygen, you can’t live without it.
Except these animals.
Zachary Laid Finding Freedom you can live without money...
@@Jackson-sr7ms not possible
THE WORLD OVER HEAVAN please explain
I am no scientist, but how do you get sulphate (4 oxygen atoms) or nitrate (3 oxygen atoms) that don't contain oxygen? 0:45 . If all the oxygen disappeared, surely all that would be left is sulphur and nitrogen and these organisms would die also
It just means if free oxygen O2 molecules disappeared
This is sk cool .. eek !
Im so excited for this. .
I hop was theyre researcb comes through :)
I love it how history is chock full of people going "Yeah, there's absolutely no way life could exist in THAT place", and then a few years later they find life in that place. Volcanoes, sealed underground caves full of acid, undersea salt basins... inside solid flipping rock...
The more we learn about life on Earth the more we can understand about life in outer space 😃
As soon as I hear Olivia's voice I get so excited! She should totally have her own show!
Its funny because people use to hate her. I wasn't a huge fan myself. She has legit gotten so much better at this though over the past couple years. She should really be proud as she found a way to improve despite some down right mean 'feedback'.
0:45 you literally have shown how sulfate and nitrate has also oxygen in it...
Another great SciShow video! There have been many eukaryotic organisms that have "lost" their mitochondria while adapting to unusual niches, e.g., many intracellular parasites have done this, e.g., Giardia. (These species were initially thought to be an evolutionary link between prokaryotes and eukaryotes, dubbed "Archaezoa", but DNA analysis revealed their true history.) Many of these also use hydrogenosomes.
Look mom no air!
FYI, for the outer shell of the lociferan, the word loricaI is pronounced with a short I sound, not a long I sound. The accent is on the first syllable. LOR-ih-kuh. It means body armor, like lorica segmentata worn by the Romans in ancient times.
Thanks for delivering us news from 2010
Me: Hears the word *MITOCHONDRIA*
Me: *TRIGGERED*
In the future, we could probably genetically modify an animal that can live on anything besides oxygen.
Not everything is down to genetics
Loricifera are extremely closely related to Arthropods, Nematodes, and Priapulids, so that's also interesting!
Literally looked and researched this. Sediment that they consume or absorb have saline in the sediment
1:49 H.P. Lovecraft would crap all over himself if he saw that. Of course, he would imagine them being 4 meters tall, not 1 mm tall.
And never mind tardigrades...
when it comes to extraterrestrial species it's foolish to think that oxygen is the only way to survive
1:53 looks like a beautiful alien flower pot
it might be in real life the super animal we don't know it
This Is something Very Important for me. For a long time, I have faith for a multicellular organism to exist that don't require Oxygen ........ but now I have some study that can finally change faith to Fact... But anyhow we need more research in the field..... This study might be important for our (Human Species) future survival.
This video wins the contest of having the most big words in it.
Wasn't that only one animal, not animals?
So, they don't need O2, but they do need molecules that contain oxygen (SO4 and NO3)
I feel low on oxygen when im around you .
Olivia
Lorficiferan looks awfully like the elder thing...
Related topic of interest: paradoxical anaerobism (not using oxygen despite its availability) in Devil's Hole pupfish.
I was today years old when I found out that one of the speakers on this channel is worth $12million
Those loriciferans are the monsters from At The Mountains of Madness O_O
0:15 ⚡Powerhouse Of The Cell⚡
It’s nice to hear someone pronounce “processes” like a human.
Living in hydrogen in Oxygen Not Included
0:47 sulfate and nitrate, are contain oxygen inside their molecule compound, do they count as instead of oxygen?
Life allways finds a way
The boarders of the habitable zone have widen.
so does this mean finding lifeforms out there in space more likely? wow!
Haha, my brain broke a little when you *didn't* say "the powerhouse of the cell" after "mitochondria." XD
Title: these living things don't need oxygen and we're saying that like it's totally crazy!
Me: thinks of literally every plant ever
Actually these compounds have oxygen that they use so it kinda doesn't count as non oxygen breathing.
Well we read it in school
But if sulfate and nitrate have oxygen molecules, isn't it like saying we don't need oxygen cause we manage with just air??
I thought that bottom of Black see has some creatures that don't need Oxygen as well...
So my question is can we redesign humans to not need oxygen and to reduce the amount of energy we need in the first place? While maintaining our intelligence.
You would have a far easier time just creating an entirely new life form. You'd first have to make us ectothermic like reptiles, and that alone may preclude intelligence. In essence, you'd have to redesign nearly every single facet of our biochemistry to make it work. But it's still fascinating to imagine possible alien biologies.
@@patrickmccurry1563 There's no reason a reptile can't be intelligent.
This isn't the first time I've thought about rebuilding humans from the ground up. We could do a lot of things, like fix our eyes, if we can figure out how some animals avoid cancer that'd be a good add. Radiation resistance and longer (or indefinite) lifespans would also be nifty.
interesting-- HOW do you think they'd handle in a closed off mason jar?
Not a biologist so I don't really know much about this, but I always wondered why we only look for other life on planets that nearly match ours, who's to say aliens need our atmospheric conditions.
why do they always assume life needs water and oxygen? just because we do doesn't mean all life does.
By golly. If Araki known about these and those bear bug things, Battle Tendency would've ended differently
Speaking of the lack of oxygen, the scene from the recent Godzilla II movie has been bugging me. If they released an anti oxygen bomb in the middle of the sea, won't that also extract all the oxygen in the water, leaving the hydrogen behind, turning it into a hydrogen bomb? Which wasn't the case. No significant amount of water was lost in that process.
Won't the amount of water displaced then cause a world wide tsunami as well? Which didn't occur in the film too.
Lastly, won't the drop in pressure in the area be so large that everything that is airborne be sucked into the vortex, including the craft the protagonist was in?
Can someone explain to me what should have happened?
I dont need it either. Ive been holding my breath for 10 years waiting for mechwarrior 5 to come out.
Animal life in the vacuum of space?!
Maybe they create their own electrolysis separating the oxygen from the hydrogen
Can we send em to mars ? In NASA's 2020 mars mission ?
Reads title..
Ya I love fish
Before you go get the bat I’m not IQ deficient. I do realize water has oxygen in it I just found it funny.
Life, uh, finds a way.
I was hoping it was a picture of Congress with a title like this!
I never understood why, when searching for life on other planets, we apparently always look for an 'earth like' planet with water & oxygen and such.
So it's means multicellular evolve 4 times independently ?
creatures that live without oxygen? perhaps truly keys to the abyss; cataclysmic potential be damned- let's go airless!
I don't need it, I dont need it, I dont need it, *sweat drops* I neeeeeed Ittt!
Me: Watch me breathe with no oxygen needed
Also me: i dont no helmet i got a plastic bag
What did she just say? Mitochondria is not the PowerHouse of the cell?
Wouldn't the fish and stuff falling to the bottom have some O2 in 'em?
How has no one mentioned Captain Olimar yet?
Oooohhh hydrosomes, what if that's what we had when we were living in the puddles of microbial stew, and the introduction of mitochondria got us enough energy to get out?
¿”Swiped Genes”? Is that horizontal gene transfer? Would love to see a video explaining that.
Found it.. duh. th-cam.com/video/tCZhkxpzxDY/w-d-xo.html
I don't know why, but this woman is pretty darn good looking oh yes sir she is *imitates cartoony dog howl*.
fair enough, got me with the clickbait.
*H. salminicola has entered the chat*
The water bear better be here
Tardigrades need oxygen, just like all pan arthropods, and their survival skills are kindve specific and really overblown.
This seems like it's a very big deal. I'll wait until an update video time actually State this finding as fact. Animals using hydrogen in place of oxygen is pretty amazing if true.
There are some people who don't need oxygen..
Life uh... finds a way
The mitochondria the PowerHouse of the cell
