In 2023, Joseph Dituri set a world record for the longest continuous stay underwater. And that 100 day stay had effects on both his body and mind. Scientists have been studying the effects of living underwater since the 1960s, but how close are they to answering just how long we could stay down there?

This video didn't really highlight/clarify it, but the notable thing about these stays is that they were done _at pressure,_ where the breathing gas in the habitat is the same as the surrounding water. This makes it quite different from submariners, who are in an atmosphere very similar to that on the surface and are just dealing with the cramped space and isolation considerations but not the physiological changes associated with breathing gas under pressure for long periods.
Helium, as weird as it sounds, is frequently used in gas mixes breathed at depth specifically because it has very low "narcotic potential". Commercial saturation divers get used to this and can converse regularly with each other despite the strange sound, and their operators/handlers can usually learn to understand them as well but communicating with other people is usually done with a pitch shifter to restore a more normal tone to the voice.
In addition to helium, hydrogen is sometimes mixed in for a similar purpose although this has additional risks/concerns due to its flammability, especially because oxygen is obviously also present in the breathing gas.
In terms of oxygen, while breathing regular air at depth means you're exposed to higher levels of oxygen which is potentially damaging long-term, it's also possible to provide a breathe a "hypoxic" gas mix that contains _less_ than the usual 21% oxygen. While this is unsafe to breathe at the surface, as long as the _partial pressure_ of oxygen meets or exceeds 0.21 atmospheres, it's just as effective at oxygenating your blood as normal air would be at the surface, so your tissues still get all the oxygen they need without being exposed to higher dangerous levels. Normally these mixes are only used at depths where the normal percentage of oxygen becomes acutely toxic (about 1.4-1.6 atmospheres of oxygen partial pressure, which occurs at 70-80m) but there's no reason you couldn't use the same trick to alleviate the risks of chronic high oxygen exposure at lower depths and partial pressures too.
The humidity consideration is interesting. If you wanted to have "moon pool" style easy access in an underwater facility, it would make sense to close that space off from the rest of the base with some kind of a door and dehumidify the rest of the working/living space to keep it at a more normal indoor humidity to prevent infections and issues.
Good addition. I wish they had clarified this better in the video itself.
Came here looking for this. Thank you for clarifying. I’m an SF writer and have been researching underwater habitats and submarines for a while now. Was puzzled because I know 9-10 month tours are common on nuclear submarines. Of course the pressure factor changes everything. Freedivers on submarines have the same problem as they are subject to high pressures where they leave the vessel.
I'd wondered whether they could've prevented or mitigated the increased risk of ear infections with regular antiseptic use, e.g. by putting a bit of hydrogen peroxide in each ear for a few minutes per day.
OTOH this video didn't discuss depth as a variable in as much, well, _depth_ than I would've liked: I've heard that longtime saturation divers (and former saturation divers) have to deal with physiological effects such as joint pain afterward.
I volunteer for a year minimum. If they're providing me food, entertainment, and a "to-do" list of tasks while I'm down there, I'd be completely content. No different than what I do now except I'm not currently surrounded by water.
Let me know how the tinder dates go.

Of course we do well with water. That's why we're called mammals. It's right in the name.

The most interesting thing from Dituri's work for me (from a radio interview I heard), was that he was naturally sleeping like 4-6 hours a night but in REM for the majority of it. He said he felt great because of it. I think about that when I can't sleep at night or wake up still tired!
It's surprising if true, because in REM, our brains are as active or more than when we're at rest. There's also too much eyeball movement in REM sleep iirc. That should leave you more tired.
@@prakash_77true it is more active during REM but that's our brain's defrag mode, the brain is busy cycling thru it's encounters and interactions from the day, deciding what to keep and the excess is dreamt away (all this while your aware self is unconscious, it's fascinating). I know this cause I wake up every 20-30 minutes and never achieve REM and never dream and I never feel rested and my brain feels overloaded before I even get out of the bed I laid in for 10 hours but only slept 2 of. Every great once in a while I'll get 4 hours straight and I'll dream vividly, those are the mornings I wake up feeling refreshed and ready for the day.
@@bradleymahurin5582 The glymphatic system, responsible for removing metabolites form the brain, is most active during deep sleep, not REM sleep
@@bradleymahurin5582 have you tried melatonin? Or 5htp? starring at the sun with your eyes closed for 30 seconds ish around 3-4pm can help your body make it at the right times!
Ummm vit b3 during the day to help with biom. Ummm yeah avoiding stimulants after 1pm including coffee, tea etc may also help! Hugs!
Let's be real though, the record for living underwater is probably some nuclear submarine crew that isn't allowed to talk about it.
There are SSBNs patrols that are known to be longer than 100 days - much longer. The odds that there's a stretch of time during those patrols where the sub is completely submerged for longer than 100 days is pretty damn high.
that is a fact friend.
But the interior of a submarine is maintained at one atmosphere pressure. IOW, the submariners are living and breathing exactly as they would on the surface, except for being more crowded. Same pressure, same air. The aquanauts in the video are living under pressure, sometimes a great deal of pressure, necessitating specialized breathing gasses. Oxygen becomes toxic and nitrogen becomes a narcotic at high pressures. And the lungs have to work harder to breathe gas that is more dense due to the pressure. Submariners have none of these issues.
The published world record for a submarine staying submerged is 111 days...so definitely.
@@mal2ksc
I don't think anybody's goal was or is to stay under water indefinitely. For some it's kind of an adventure/vacation. For others it's research on human physiology. The ones that stay at shallow depths (maybe 20 feet or less?) would not require any decompression. The deep ones would require a chamber, as you say, the same as deep-sea saturation divers.
submariner here. can't confirm. lol. but yeah, we go significantly deeper and longer than this. Sorry, @SciShow, but this is snoozenews.
I’ve been playing subnautica for the past 3 weeks and this video is perfectly timed
Eyyyyy I was looking for the Subnautica comments. 😁
I love this, it's cool to see humans pushing the limits of what's possible.
As long as it's not pushing for meaninglessly dangerous or unhealthy goals/behaviors to be accomplished "just for the sake of it". I could kinda understand people who just enjoy extreme things to a degree, but there being a social pressure to do things just to break records seems silly when it potentially hurts or kills people. In this case of this stuff though, I guess it's more about the research than the "accomplishment".
@@Aeduo though I 100% agree sometimes people have to make sacrifices to help the rest. Luckily over time I think we have figured out how to do this more safely, still you can only do so much.
But I agree, nobody should be forced into it and they should fully understand what they get themselves into before they do it.
@@DoubsGaming I think a lot of cases in history where people needed to be put to extreme circumstances to save the rest tended to be contrived situations, unnecessary and just and assertion of cruelty in some way or a situation which had been known to be getting so bad and nothing was being done about it.
The Subnautica experience
“Detecting multiple leviathan class lifeforms in the region. Are you certain whatever you're doing is worth it?”
Man just needed some time alone to chill and came up with this idea :D
Great job. One of your very best.
It's so weird to me that people talk about how hard it is mentally to live alone for periods measured in days. Like seriously? Give me years, I'll be happy the entire time.
I think it's more of an issue on a genetic/biological/species scale. Humans are social creatures by evolution and so maybe on a physical level and on a mental level you would be fine for a while you would still probably end up w negative effects due to isolation.
Some people just need more connections.
If it's 100% voluntary and you're in control of how much or how little you socially interact with others, that's very different from forced isolation like you have with solitary confinement.
Which I suppose is another way of saying, "A man chooses, a slave obeys."
Same. I think I could be quite happy that way as long as I could bring my cats. And as long as they were happy and healthy. And as long as I still had email and/or text. To be honest, I found the quarantine of the pandemic to be refreshing because there was less expectation for me to socialize. I think there is a big, big difference in how introverts and exteoverts would view the the isolation in some of these experiences.
@@rocketterrierSome people just don't care. I go weeks without seeing anyone, years if you don't count delivery people.
@1:50 She says they want to breath less because it is more exhausting to breathe dense air. But the more obvious cause is because there is three times more oxygen per breath, so they just don't need to breath as much, also explains the lower heartrate and BP, their oxygen saturation was probably consistently really high.
Great video. I have to admit, I thought you meant actually living in the water. That would be something. This seems more like living under pressure, and the water just happens to be there. Does depth matter for this record, or can the top of the structure be just a foot or so down? edit: Why doesn't the 111 day, longest submarine dive, hold this record?
I thought that at first, too. Like, how does he manage to eat while in a scuba suit under the sea? 😅 Good questions about the record(s) and deprh, too.
Exactly, being underwater is not relevant - it's just living in a pressurised environment. That's why this was a world record - not because he was underwater.
And also the physiological outcomes are totally irrelevent for a space mission - if anything a spacecraft to Mars would probably be kept at LESS than 1 atm pressure.
Submarines are kept at the same pressure and air mix as of you were on land. So, not the same conditions in terms of a record.
@@ketchup016 Understood. So what are the conditions? Can they just be a foot underwater, at that pressure? If this is really so cryptic, why didn't SciShow lay it out? They just said underwater.
I learned, rather painfully, while I was at space camp as a teen, that I cannot scuba dive. The pressure at just 10m down triggered the worst migraine I've ever had and I've dealt with them all my life, so that's saying something. Otherwise, I would love to try living under the sea like that. I'm already a fan/proponent of the tiny living movement, so the small space wouldn't be a problem for me at all as long as I had communication access. Perhaps if such a living container could be fitted with a decent and clear window, or perhaps a periscope, and anyone down there had at least 2 hours a day of access to stare out into the distance, perhaps in 30-minute intervals, that might mitigate the temporary vision issues? Or maybe VR?
Yes, it's better down where it's wetter, under the sea. Loved the reference!
Give a Twitch streamer the best gaming equipment, and they could live down there for years without a care in the world about where they are.

Why not Subnautica?
I hope you do a follow-up on this video when he's given his findings!
I cannot help but have Queen's "Under Pressure" stuck in my head now.
I'm glad this kind of research is ongoing. I don't think we need to have a real-world "city of Rapture," but even something as robust and roomy as the habitat in the film "The Abyss" would be AMAZING. That had open-to-the-water areas as well, if I recall...interesting to think about how damp everything would end up being. They could control some of that humidity with airlock-style doors between sections, perhaps, but it's still the kind of thing you might not immediately expect to encounter.
I would have also liked if y'all had mentioned the other professions that regularly spend an enormous amount of time living under water in pressurized capsules, like the incredibly brave people who handle diving for oil rigs - from what I gather, they stay down for a week at a time, that's one shift for them, and it takes two days to get down and another two to come back up due to the decompression thing. And they're at massive depths, we're talking "bottom of the Gulf of Mexico" depths, and having to watch over massive pieces of machinery.
There's lots of mentions of submarine crews - but I have to say, from what I heard from an uncle who was Navy, it's a bit of a misconception to say they stay down for six months straight? The ship does dive deep and stay down for hours, maybe even days, but not months. Now that could be different now, my uncle was in the service quite some decades ago, but if they still have to basically "refresh" their air supply on the regular, then they can only stay at depth for so long. I read someplace (can't cite a source, and if y'all can please correct me!) that the "scrubbers" only last 30 days, and changing them takes long enough that you wouldn't want to try doing it while still at depth.
Thanks. Now I have the earworm. LOL. The Abyss is one of my favorite movies. I read a lot about Tektite ii when it was active, there were several articles in National Geographic magazine but I can't remember if the Habitat was open to the sea like the Abyss. Makes sense since they live at the same pressure as outside. My understanding of Nuclear submarines is that they can stay down until they run out of food as long as they have power. They have machinery to provide air and water. Better than the Apollo 13 scrubbers. Since the Kitty Hawk (Aircraft Carrier) was decommissioned in 2009 all US subs and carriers are nuclear. According to Google 😁
As a fan of Sealab 2020 and SeaQuest DSV, this seems to be a good idea if done properly
@shaider1982
Play the video game Subnautica, you'll love it.
It is cool! it's inspiring to watch humanity pushing the boundaries of what's possible!
I mean… submarines are a thing
they aren't a residence, they're a vehicle. You don't live in it, you serve in it.
They don't go that deep
Except they surface roughly every 2 weeks
@@josephgermany7446 nukes don't when on some types of mission.
Even nuclear subs tend to come up fairly regularly though. So while you may be on the sub for months at a time, up to 6 or more, you aren't under water anywhere close to that entire time. Coming up to the surface pretty regularly.
Kudos to the script writer for all the puns. Thoroughly enjoyable.
Are you sure 100 days is a record. Some of the surveillance subs like the Nautilus stay submerged for very lengthy tours.
Subs are kept at near sea level pressure.

He missed his daughter's graduation for this. Now whether or not that was not okay to do it depends on every family situation and individual relationships.
But that being said I would love to see a video on the personal cost of scientific breakthroughs that pioneers have had to go through in the past?
I did my masters working under someone that’s probably going to be considered a pioneer in neuroscience. Anecdotally I would say that at this level, most investigators are both extremely cemented in habit, such that their lives are built around it, and if those they interact with are not involved in that habit they have some sort of glaring deficit in their social function
I watched my daughter's graduation on zoom. Since we were at the opposite ends of the country an neither of us felt it was a big thing like a wedding.
My cousins don't think graduations ceremonies are a big thing and have skipped their own after high school. I like to see them graduate but I am not in charge.
He could have chosen any time to do his experiment, but he chose a time that he knew would make him miss the graduation. I have a really hard time calling this a "personal cost of scientific breakthrough" when it was completely avoidable (and not terribly scientific). My daughter's not even in kindergarten yet and I can't imagine intentionally missing such an important event.
This is one of the few times I was woefully underwhelmed by a SciShow episode. Maybe establishing the difference between an “Aquanaut” and a “Submariner” as a baseline might have made it seem more interesting, but Boomers go out to sea and stay under for Six months straight. Tens of thousands of Sailors have done that.
Submariners are living at 1 ATM pressure, just like on the surface. The aquanauts in the video are living under pressure, sometime extreme pressure. This has enormous effects on the body, both from the pressure itself (it's harder to breathe when the air is more dense) and from the need to breathe special mixed gasses due to the fact that oxygen is a nerve gas at high pressure and nitrogen becomes an intoxicant.
@@danielschechter8130 Would've been nice if they explained that in the video. Hell, thanks to the pictures they used for the first few minutes I thought they were IN the water for 100 days. Even when they said "thick air" I thought that was a euphemism for water.
The quality has been going down since the budget cuts that axed scishow space, scishow psych, and some of the presenters.
Honestly I am kinda surprised people didn't pick up on that fact. If you were too dense to miss the whole "living under pressure" thing, you would question why this video even exists. It should be obvious if you thought about it for more than a second.
@@mal2ksc
There are definitely limits to time spent under pressure. Deep-sea divers experience a wide range of health issues, which is one reason they are paid so highly. I imagine that deep-sea research habitats would use the same system that deep-sea divers use: The habitat is at ambient pressure at depth, and at the end of their stay they are probably brought up in a chamber that allows them to decompress gradually on the ship, in a dry environment.
i wanna play subnautica again
You should. It's great
It depends enormously what biome you're in and what mods you're running
Well, Sebastian already told us that it's better down where it's wetter.
Reminds me of some soviet era romance I read. With researchers at the bottom of the sea, and I think they had to evacuate to the surface because there would be a tornado that would ruin connection lines and deliveries etc. I don't remember exactly, that was a long time ago. Science fiction, probably.
Thanks 👍
Amazing informations 👏
Y'all ever read the book Riptide? Pretty good book about a group of family's that live and farm underwater after ocean levels rose massively. They lived in homes modelled after deep sea animals so they wouldn't be crushed and whenever they had to go out they'd breathe in this special liquid that would supply them oxygen for a certain amount of time and once they breathed in air it would dissolve and they'd cough it up.
For a larger habitat it may be possible to have several internal airlocks to successively lower pressure (and more strongly built) sections. So for example, it might be possible to go further in for a drier and lower pressure sleeping area.
If you change the pressure much you have to decompress. Drier would probably be more restful but these are marine scientists. The air near the ocean and on boats is damp a lot of the time.
"We call out to the beasts of the sea to come forth and join us

LOL'ing in a Qualified Submariner
perhaps i intuited a signal in the collective subconscious, ultimately eliciting my seemingly random regurgitation of the lyrics for "Astronaut in the Ocean" the morning before the night of this video's upload.
Funny that I happen to be in the middle of my first playthrough of SOMA when this video gets published. :P
Where do I sign up?
what i want to know is that if reducing the percentage of oxygen to offset the density difference, could see habitats become a possible extension of housing in the future? i mean it's would be A LOT like those "steel houses" they we're making back in the 60's but with improvements to technology along with an accompanying rail way for travel it could become an interesting concept.
I think I'd have trouble with two things: the idea of it possibly leaking, especially when I'm sleeping (assuming it would be pretty deep underwater), and having to work harder to breathe. Maybe you get used to breathing like that, but it would be really easy to feel like you weren't getting enough and to panic.
I'm not buying the "work harder" to breathe thing. If the pressure is higher than the gas exchange in the lungs should be easier, resulting in normal 02 levels in the blood with less effort. I think it would be easier or the same to breathe under pressure, excluding breathing from a tank while surrounded by water.
The success of an all female crew of scientists and one engineer: Ann Hartline, Sylvia Earle, Renate True, Alina Szmant, and Peggy Lucas Bond spending 14 days in Tektite II gave NASA data to help it decide women fared as well (and sometimes better) in difficult conditions. This contributed to the choosing of female astronauts in the US.
If the documentary series Sealab 2021 has taught me anything, it's that living underwater for long periods of time make people go crazy, and also more prone to exploding.
"Blueprint acquired."
Back on the ssn723 we spent WAY more than that, only surfacing for reloading food every 4 months.

Looks like the looking glass station from LOST but without a moon pool
The Helium is used as an inert gas that doesn't affect the body. Under pressure, if there is too much nitrogen, you can get the bends, if there is too much oxygen, it's toxic as well (recreational divers can't go above 1.4 Partial Pressure O2, so if you use Nitrox, that is a mix with more O2 than normal and less nitrogen to avoid the bends, you can't dive as deep), so what they do to reduce the oxygen and nitrogen is to introduce an inert gas, like Helium.
the bends is only a problem in decompression, excess nitrogen causes narcosis below 40m deep 120ft
@@bernhardjordan9200 Yes, but if you're going to stay deep for a long time, you want the gas you're breathing to contain the minimum nitrogen possible, so you can get quicker to the surface later. I'm not sure the pressure those aquanauts were withstanding though.
@@javiTests 6m, 20ft, is not that much, like a diving swimming pool.
I don't know if you can run to the surface but for sure it won't take a couple of hours to decompress
Long decompression time is found in deep diving like in the petroleum industry but those guys go more than 300m 1000ft deep
@@javiTests helium is not used for being noble but because it's light and fast it doesn't causes narcosis and scraps easier from the blood
If what you want is a noble gas argon is way cheaper then helium
@@bernhardjordan9200 I'm not sure what your point is. I saw they were surprised they used helium and I explained why it's quite common to use helium under pressure to reduce the amount of oxygen and nitrogen at the same time, since both are bad when the body is under pressure, that's it.
I'm surprised there weren't mentions of submarines. Google says they can stay up to 3 months underwater with their standard food supplies.
I know this sounds like an obvious question, but why can't we have an airlock system that keeps the interior at atmospheric pressure? that would avoid some of the problems with air density.
A possible answer could be cost. I imagine that it may be cheaper to pressurize the whole vessel than to have to add additional structure to deal with the ocean pressing down on the hab. After that is taken care of you would then have to design the airlock system. Water is dense, about every 10 meters is another atmosphere of pressure.

My only initial thought is that half of these people wanted to see if they could suddenly breathe underwater after enough time there..
Conduits are a thing, and they allow people who are near to them to breathe underwater, making oxygen tanks redundant, no wonder why the person who has spent the most time underwater without resurfacing just so happened to have lived near a conduit the whole time.
@@candyneige6609 in my world a conduit holds bunches of wires? What does it mean in yours?
@@mcspikesky The word "conduit" actually has 2 definitions, the first definition is what you've just said, something that holds bunches of wires, but the second definition is of course a device that allows anyone near it to breathe underwater pretty much forever, and believe it or not, both definitions are applicable to both of our worlds because they're both actually the same world, the real world, so with a conduit, you can either hold bunches of wires or breathe underwater, but it's this second definition that we're interested, and actually, conduits of the second definition are often called "underwater conduits" to avoid any possible confusion, so if we want to breathe underwater, we have to be near an underwater conduit.
This is almost purely a PRESSURE test with low living area.
These experiments are done with high pressure that is needed to stay within surrounding water pressure. That is not needed, but for easier control for the environment and having more structurally stable housing units. Also having an open port to the sea you'll need high air pressure.
If you make a huge underwater habitat, you may make the pressure lower than surrounding sea. Staying under water should not mean just staying under higher pressure that causes problems.
You may compare this to space missions, where the pressure is much higher than almost 0 in the space. It would be pretty short timeperiod that the astronauts would be alive in equal pressure that their surroundings are.
6:17 "so maybe it really is better down where its wetter" 😂
As long as I'm left alone, it sounds good to me. I'd worry about the internet, food, and such (would DoorDash deliver? LOL). Zoom and/or Facebook would keep me connected with people. With all those aspects smooth, I'd prefer to have an underwater habitation. The air would be cleaner (expectantly), and no noise. Seems a healthy way to go.
honestly, I have joint damage. Spending a lot of time in the water would probably let my muscles strengthen, and my joints recover.
I think Warsprite was underwater for 111 days on one mission.
sounds fun. I volunteer to stay longer in the underwater habitat than the longest time spent in space.

This person is my absolute favorite presenter and I don't even know their name.
Also, I thought folks on subs went down for a long time.
it's always in the description
Thank you, I see it now! I'm also glad that I defaulted to they/them pronouns because it looks like those are appropriate.
octonauts theme song plays
How is it different than pandemic life? Psychologically, if you’re isolated and distracted by media and tasks, doesn’t really matter if your on your couch or an underwater lab.
Could the eyesight thing be counteracted with VR?
As someone who has a consistent desktop computer habit, no. No it cannot.
I mean the eye doctors have a machine that auto corrects to your vision so you can see that house in the distance. Unless I have no idea how those machines. They seem promising for the vr screens
@@thomasrogers8239 What does that have to do with VR? I think all that is needed is to exercise the eye muscles by focusing on a point in the distance. Since we can't literally look at the window we will need to create an image to focus on somehow.
VR only mimic distance with stereo vision, they don't mimic distance associated with focus
The longest time a nuclear submarine has been submerged is about 400 days. The Soviet Navy's K-222 set the record for the longest submerged deployment of a submarine in history when it stayed underwater for about 400 days December 1969.
This is significantly longer than the stated time periods in this video.
Wow
Would you kindly, demonstrate the helium effect.
lol
So ya saying it's way more peaceful to live under water? Sign me up! I'ma bioshock nut and I love a mix theme of steampunk and nautical environment. Yey! ^^
me sitting here with a nasty thriat infection and the idea of staying several weeks underwater in a cramped amd damp environment just gives me serious anxiety
I'm little confused now because I was pretty sure that submarines stay submerged by couple of weeks or even months and much much deeper than 60 meters. So I don't see significant differences between submarine's crew and 'aquanauts' (in living conditions, exposure etc). Meybe I'm wrong about the time that submarines spend submerged...
As stated in other comments, submarines are at atmospheric pressure, and not directly exposed to open water for frequent dives
As an introvert with debilitating social anxiety, I would happily live where I can never be bothered.
oh no... I've played BioShock. you're not getting me with this one
I couldn't go that long without internet.
Good news you can get internet with the right equipment underwater.
Why is the habitat named after the giant jumping one-eyed bugs in Zelda games?
Some of us have done this for a career living in cramped spaces underwater for months on end, it’s called serving in a submarine
Does the high pressure oxygen increase the saturation of haemoglobin at all? That would account for reduced respiratory and heart rate
A good thought, but no. For a normal healthy person their haemoglobin is already near-saturated with standard air and pressure. You can see this if you google "oxygen-haemoglobin dissociation curve". You can *slightly* increase the amount of dissolved oxygen in blood by increasing the partial pressure, but as noted by others, this is quickly limited by oxygen's toxicity.
Wow really
Jacques Cousteau though people could live permanently under the sea. The catch was he wanted them all to replace one lung with an oxygen tank and a machine to diffuse it directly into the blood.
I imagine James Cameron would love to make a movie about this-oh wait he kinda already did. The Abyss. Honestly not a bad movie in my opinion but not his best. Though in THAT movie he really pushed the limits of "underwater science-fiction" with stuff like breathable liquid and defusing a nuclear warhead at the bottom of the Marianas Trench.
100 days is nothing. I'd easily volunteer to do far longer than that without any contact at all. It would be peaceful, and the time would pass quickly. I'd love living underwater, it would be amazing. Though, the humidity would get old fast.
Can you sign up for this?
I read this title super fast while scrolling. I thought it said "How long can you live in your underwear". Lol.
can i go with him to keep him company???
If this was a fiction movie, he would totally grow fins after that long, but nope, his eyes just became worse.
Maybe his eyes were preparing themselves for direct contact with seawater by growing an extra layer of almost transparent skin. The fins come later, after the eyes have transformed.
send me back to the sea, where I belong, fish brain says this is the only way to happiness now
What about submarines? Don't people often stay submerged in them for considerably longer?
what about submarine crews?
I know his fingers were crazy pruney 😂
Huh aquanaut I think I learned a new word today. I’m guessing it’s inspired by astronaut. Oh turns out aeronaut is a thing too with like planes. There’s a tv show called “Octonauts” they have a submarine and a song about the creature reports. *What are some other ocean themed shows?* There’s “The Deep” they also have a submarine different vibes though. There’s “H2O Just Add Water” they sometimes swim in the ocean because they’re mermaids. There’s “Zak Storm” he’s kinda like a pirate and his ship floats across the ocean in the Bermuda Triangle. There’s “SpongeBob” I’m guessing most people have heard of that one. And there’s “Bubble Guppies” they’re mermaids too and go to school and whatever. Btw the ones I thought of are mostly kids shows and most of them are cartoons. Plus there’s lots of other’s as well.
Y’all can have that. I’m good
"Moscow" ship will live there for eternity with all its crew onboard :D russians say it was planned so it's seems working just as intended
Bioshock flashbacks ensue
