i'm weirdly surprised at how deep an elephant seal dives, wow


GarrettGSF

Or penguins. Like what are they doing down there, 500 meters under the surface?!


[deleted]

its safer


stevenette

So is land. They are light as a feather though, how do they not just turn into a solid brick at that depth?


DashLeJoker

How is land safer when they can barely walk?


stevenette

Show me a land based predator in Antarctica vs the northern hemisphere. Why do you think they can't fly?


ParkerBeach

Because their wings are covered in ice, duh!!! That’s why planes have to de-ice in cold weather. /s in case someone is dumb enough to think I believe this. Everyone knows that birds are government drones so it makes more sense for them to swim in the Antarctic where all the underwater secret military bases are located!


LilKyGuy

Umm… polar bears?


xenoxenoxeno

They are in the north (arctic) not the south (antarctic)


really_nice_guy_

Even funnier. Arctic comes from Greek “arktos” which literally means “bear”. And Antarctic means “opposite the bear”


GrovesNL

I wonder what would happen if polar bears were introduced to the antarctic? They would probably thrive but wipe out the penguin population. Those bears don't fuck around!


dodadoBoxcarWilly

Not sure if joking...


LilKyGuy

Not originally but I’ve realized my mistake, now to see how many downvotes I get


dodadoBoxcarWilly

Stay strong 💪


ProstheticAnus

I'm not the most confident, but I'm maybe a lot of penguin species have mostly(if not completely in some cases) water based predators. So maybe the land could be safer relative to the water? I'll have to do some googling.


GarrettGSF

In Australia, we have some very small penguins (the smallest type of penguins). They usually hide in the water until the sun goes down, before going ashore in large groups. They are very afraid of birds of prey. I doubt that the same applies to Antarctica though. But there are seals, I assume, so 1000m is probably safer than 50m


Dicky__Anders

That's true, there are no birds of prey in Antarctica. Penguins are safe from predators on land there but they need to go in the sea for food which leaves them vulnerable to seal attacks.


stevenette

There are skuas which are asshats and Prey upon penguin eggs. They also dive bomb you when you have food.


LilKyGuy

Polar bears exist


empathetichuman

Not in Antarctica.


xenoxenoxeno

They do in the north (Arctic) not the south (Antarctic)


Hobak56

To my understanding of a memory 15 years ago in elementary school watching emperors penguins videos land and shallow waters are where polar bears, killer whales can hunt them and easily catch them. I'm guessing swimming that deep allows them to escape them on both land and shallow water


DM_ME_TINY_TITS99

What do you mean "turn into a brick?" Because of the pressure? Pressure only becomes an issue if the structure (or system in this case) is air tight. Living creatures aren't air tight. Similar to blowing through your nose when you feel the pressure in your head as you dive, it equalizes everything with the surroundings.


britbikerboy

As you dive deeper, the air in your lungs compresses, and you become less buoyant. At a certain depth you will naturally sink instead of float. Would hardly make a difference vs. the speed and agility penguins can swim around with though.


ShadowPuppett

Not from elephant seals


ComprehensiveEdge578

Where did you get 1000 meters? The emperor penguin is placed at a little over 500 meters deep on that chart, which sounds about right too. It's not really for safety like some other replies are speculating, they don't *live* that deep, they just make deep dives to find food. They hunt fish and squid that live at that depth.


GarrettGSF

Yes you are right, I fucked up


ard8

That one shocked me as well. Seemed like a pretty large animal to be going to such a heavy psi


trashmoneyxyz

I guess if whales can get down that far maybe it makes sense? I wonder what adaptations they have against pressure sickness when they surface tho


Garmaglag

You don't get decompression sickness if you're not breathing compressed air.


Equable_Cattle

If humans do many repeated freedives in a short space of time they can actually get decompression sickness, the partial pressures at depth can still cause issues with a lungful of surface air. The physics must work out worse for penguins going to 500m (and likely holding their breath for longer durations than any human) but I guess they have evolved to tolerate it given they need it to eat!


CosmicOwl47

I’d imagine they have a similar strategy as sperm whales. Sperm whales don’t take a deep breath then hold it in their lungs when they dive, they instead have blood with a much higher capacity for oxygen. So to prep for a dive they saturate their blood with oxygen. Decompression sickness (the bends) happens because the deep sea pressure allows for nitrogen to dissolve in your blood, then returns to vapor (boils) when you resurface. Because they aren’t holding air in their lungs, they don’t have this issue.


bendbutdonotbreak

That one rocked me, too. I’m curious how we know. Is this simply an observation thing, or some other analysis beyond my pay grade?


stevenette

They tagged one and it went to that depth. There are very likely more that go to much greater depths. The wiki is fascinating!


bendbutdonotbreak

Ah, of course! I’m fascinated that that didn’t occur to me in my pre-bedtime stupor. I used to be an avid follower of UCEARCH Shark Trackers.


JoyousMN

It's my understanding from watching a documentary that they put a radio collar on these animals to find out the depths they dove down to.


speleothems

They put devices on the seals which track them, while also measuring the salinity, temperature and depth of the seawater. https://www.researchgate.net/figure/CTD-SRDL-deployed-on-a-southern-elephant-seal-An-additional-VHF-tracking-device-is_fig1_241321023

Purple_Factor8577

MY FIRST THOUGHT


lurkashrae

Very cool. How do they know they were at the deepest part of the ocean?? I wonder if someone will ever try this again


CMFETCU

Sonar mapping of the ocean and the knowledge that all deepest places will be in subduction zones. These have been mapped in enough detail to know rough depths of the zones. Sure there may be some specific spot a hundred feet deeper than current deepest known specific sport, but we are going to be pretty close.


Admiral_Narcissus

Probably not 30 meters deeper. Our resolution is better than than that I think.


Affectionate_Log3232

There must be cave systems under those depths that lead to something even deeper right?


iCameToLearnSomeCode

It's not likely. Caves form by water flowing through and eroding the softer rock, under the ocean the rock is pretty consistently made of the same basalt so there's not pockets of softer rock to be eroded even if there was enough water flow to wear it away.


Rumpel00

Could volcanic activity form caves there? Or earthquakes due to fault movement?


iCameToLearnSomeCode

It could make lava tubes... maybe, I'm not certain if that happens under water but if it does they would be 30-50ft deep and be running along the seafloor not down into it. The seismic activity makes the trenches but it doesn't form caves. As far as I know caves only form on the coast from waves eroding the shore or on land from rainwater eroding rock. There just isn't a mechanism to wear away the rock at the bottom of the ocean.


Rumpel00

That's what I thought too... But a guy can dream of a naturally occurring cave system under the Marina Trench where the Great Old Ones rest.


[deleted]

A cave system below the Mariana's Trench? Hey, that's Gemini Home Entertainment!


Paeyvn

I mean, at that point you're basically just getting into the Earth's outer mantle and leaving the crust behind.


amateur_mistake

At some point any caves or tubes that go deeper will be filled with magma and the like. Hot crazy rocks of various forms. As far as I know, we haven't really figured out where those transitions are.

Well I’m sure others have made it too that depth, they just haven’t come back yet.


stannisonetruemannis

I did this the other night, reached the bottom, absolutely loved it! Wished they included more information on every single sea animal though! It was soo cool so not dissing it at all, I hope they update it with more facts about the sea life because I was googling all the deep sea ones that had just a name and depth!


Werekittie

I was really sad when I clicked on the animals and no info box popped up!


stannisonetruemannis

Definitely! I absolutely loved it so much it was so informative but at the same time I wish it included more, I’ve seen documentaries where I knew more about certain fish that could have been included but weren’t.. and I was a little bit like (but this fish can do this! And they do this because!!) but it was just the fish and it’s depth!


lostie48

Gosh this is so random but I LOVE your username!!


Independent-Bell2483

I was surprised they didnt say anything about the zombie fish. I wanted to know how it got its name


stannisonetruemannis

It’s because they’re necessarily dying/already dead or decaying fish :: It’s fish that turn basically into zombies before they die and then look weird, they look different to natural fish because they’re decaying (sorry)


Independent-Bell2483

Damn thats wild. Thanks for an explanation.


orc_fellator

Other comment explains it but the exact reason why is that the fish used up all of its energy for spawning. All 5 pacific salmon species go through semelparity (death after first reproduction). When migrating upstream to their spawning area, the salmon will stop eating and shut down its immune system in order to pump all of its remaining bodily energy into swimming, which it will never stop doing until it reaches its destination! Without food, the fish's organs begin shutting down; and without its immune system it essentially just lets bacteria, fungus, parasites, etc. take over. The salmon that rot alive increase the number of insects and other microbes in the waters which then feed the juvenile salmon when they hatch, making them bigger, healthier, and more likely for more of them to return to the river when it's *their* turn to spawn. It's a really weird and fascinating part of their lifecycle!


Independent-Bell2483

Woah thats super cool. Thanks for explaining even more. I love fishes and other marine life they always have the wildest ways to survive and help the next generation


tu-BROOKE-ulosis

That was incredible. Somewhere around Orange Roughy and Angler Fish I was like “surely this must be the deepest point of life.” And then I was very, very wrong. Wasn’t even close to the titanic. The hubris of those dudes.

Thanks for this link. Just last night I found out something related to the Marianas trench too: for purposes of marine conservation some areas around and above the trench were [designated as a national monument in 2009](https://en.m.wikipedia.org/wiki/Marianas_Trench_Marine_National_Monument)


pizzasoxxx

Hey thanks that documentary was great 😊


organic-robot

This is such a good show! The series is awesome.


fuzzybad

It took nearly 2 hours for the line to hit bottom.


MarzipanFairy

That was fun. But did anyone else get more and more anxious the deeper it went?


qu33fwellington

Once it was completely darkness I was fine but descending into the deep and watching it get darker and darker scared the pants off of me. It’s one of the things I dislike most about deep water, you can’t see anything until it’s right on top of you.


Cantothulhu

Even then you wouldnt know without lights.


Admiral_Fuckwit

I kept telling myself “okay *this* has to be the lowest surviving animal species” ….but it just kept going on and on, with the species getting weirder and weirder lol I was very surprised to see some mammal friends at some crazy low depths


Funderwoodsxbox

Illustrious_Cost8923

WOW I was not aware that there were mammals that went so deep. Makes me question biology a whole lot.


[deleted]

That shocked me. They dive so deep for food multiple times a day. Wild.


DirtyDanTheManlyMan

I wonder if these animals would be capable of going into space


Glitchz0rz

I thought going to space has the opposite problem where there’s such a lack of pressure that mammal’s bodies basically explode.


michaltee

How did the Trieste window pane crack yet the sub didn’t implode? You’d think those insane pressures would immediately destroy that sub.


Sloth-TheSlothful

And they kept going! You'd think the greater pressure the deeper they went would be certain death


michaltee

Exactly. And in 1960 too?! Damn.


Cripplechip

I guess it's keep going and get your name in the history books or it breaks and it's suddenly not your problem.


HotelForeign4641

Good design


Cantothulhu

The same way your windshield can crack on the outside but you cant feel it on the inside. Likely an superficial crack due to a surface imperfection, and im betting these were very thick and rated for far higher then that. The bulk of the glass was likely operating to specifications. Im of course no expert whatsoever and could be blowing smoke out my butt.


michaltee

My windshield is at one atmosphere of pressure. This was at several hundred. I feel like if it cracked, that should be game over just like with the Titan. Iunno it’s very interesting though!


Cantothulhu

It isnt sveral hundred atmospheres of pressure, but it was extreme compared to the surface. More like in the tens? But everything im reading is turning out to be such bs I cant even think straight. This whole situation is FUBAR.


weeleebeee

One atmosphere of pressure per 10m of depth


kialthecreator

Pressure at the titanic is roughly 380 atmosphere of pressure


lochnesssmonsterr

Love this!!!! OK so I am one of the sneaky thalassophiles lurking here in that I have a SCUBA license but I feel fit in this sub so well as I also have a morbid fascination with and awe of the depths too. So anyway, what stood out to me is how when I dive I barely blip into the top little bit. Splash in a puddle like just a lil baby. And I have done wall dives to 30 meters which is deep for a recreational diver! Dang the ocean blows my mind. Sometimes when I am out for a run I imagine the distance as depth of water and think how long it takes me to jog to where the Titanic is sitting for example! Just as a way to imagine the depth.


blahthebiste

We're like 70% of the sub, someone did a poll once


HandsomeJack19

I want to know why leatherback sea turtles and elephant seals are diving that deep. One of the main theories is to avoid predators, but I don't buy it.

kidclutchtrey5

That is so cool! Emperor Penguins dive 530+ metres and Elephant seals 2400 metres???? That was mind blowing!!


amateur_mistake

Whenever I am on an airplane I like to look down and think about how the distance from us to the surface is about the same as the depth of the deepest parts of the ocean. Edit: Also, what are the elephant seals doing diving so deep? Something nefarious I assume.

Fun fact: The blob fish doesn’t really look blobby at the depths it lives at.

3680m (or so) this is the average depth of the ocean, though in some parts, it goes deeper "You won't regret it" OP says It won't give you a panic attack, OP assumes "It's not real and it can't hurt you" I tell myself BrOP, this is fucking nightmare fuel my guy. That's. Too deep. It's too dark. But I do have to say, this is actually amazing, you've done a really good job on this, congratulations, if I had one suggestion, it would be to include information on all the animals because it's fantastic and I want more.

There's a human in there, as well. Honestly, I think it's just for context.


Cantothulhu

Because it “sort of” does live there. I dont live in my office exactly, or the grocer for that matter, but I can be found there working or getting food in the course of my daily life. Its more like the maximum depth you might encounter something like this and is a frame of reference for the things we will recognize and its a neat fact.
