When I look a deep sea animals today, it makes me think of what kind of deep sea creatures existed back in different time periods of earth’s history, it could be stuff we have never even imagined being possible

[@TheIronTemplar93]

Unfortunately, it's incredibly likely deep sea animals won't fossilize. The low energy lifestyle most of them follow has reduced their bodies to almost gelatinous in structure. Add to that that any amount of sediment needed to bury a specimen is not likely to exist in the low flow of the deep sea floor. In addition, if anything in that environment dies, it's practically guaranteed that everything in the immediate area is going to take as much advantage from it as possible. Finally, tectonic forces would be necessary for the fossil to actually be moved somewhere where it can be discovered, which could take millions of years

[@Sparky579]

what if some never went extinct, in the first place?

[@TheLA384]

I think it depends on how much the environment down there has changed over the years. It's possible that it's mostly the same as millions of years ago, then there would be no reason for species to go extinct or mutate.

In my humble opinion, the freakiest deep sea animal has to be the barreleye. Even without knowing that they can rotate their eyes like that (I learned something new today!), it's just the weirdest that they have their eyes inside of their head. It upends our intuition about what eyes are and how they work in a way that no other animal does. That's why, to me at least, there's not even a competition about which animal is the freakiest.

[@Brambrew]

It's not "survival of the fittest" as much as "survival of whatever works well enough," leading to a multitude of strange adaptations and mysterious animals in our planet's deep oceans.

[@alexhooijschuur5131]

This is a sentiment that definitely needs to be more common for the public to adequately understand natural selection. That being said, Fitness in biology refers to an organisms ability to successfully reproduce in it’s environment. Survival of the Fittest therefore describes the propensity that organisms which reproduce most successfully in their environment pass on their genes at higher rates, thus the traits which aided their reproduction will also propagate. The keyword is “most successful”; there is indeed no such thing as perfectly adapted: the world is in constant flux, and genetic changes themselves are mostly random and only refined by the process of natural selection. “Fitness” in biology does not mean what it does in normal contexts. It’s a classic case of the public confusing a scientific meaning with a similar colloquial one.

[@Axios-Lux]

"Well enough" is fitness, relative to your environment. Fitness relative to your competition in that environment is where that term came from and it's accurate more than not. If you're at good enough and they're at amazing, you're likely not going to make it long.

[@FlyingDwarfman]

Sort of. "Fitness" in evolutionary biology means, very specifically, "what works well enough [to contribute to the next generation's gene pool]". The misconception is less that we should use a different term and more in what that term means in everyday, colloquial use versus a specific academic field.

[@gwyndolinstentacle4785]

It all seems so pointless though,isn't it?Like why are they drifting in the ocean floor like that just to catch prey occasionally and repeat this process over and over again?

[@richt7525]

​@@FlyingDwarfman Was headed here to point out what you did pretty well. Overall, though, there seems to be an assumption that evolution is *solely* driven by beneficial behaviors and/or mutations that better suit the organisms in question, but this is not always the case. And that's why koalas and pandas are a thing lol. Then there's the human factor- sure we're *great* at pushing species to the brink of extinction and beyond with our own behavior, but then we turn around and try to save others with almost no environmental impact, such as the aforementioned panda. This means that you could argue that we are the primary force driving their current and future evolution. The human factor overall is likely sparking adaptations that don't necessarily amount to the alteration of some species' environment. Evolutionary theory is long overdue for an overhaul and fresh coat of paint. I'm with Ian Malcolm on this one.

@@JanKoci nice paper (I saw it in Molecular Ecology). Do you work in academia or in private industry?

[@JanKoci]

@@----.__ sex as in "meiosis and recombination" 😂 in case of the fish the asexuals are all female (typical in biology) and they actually do mate with males of related sexual species. But the gametes (egg and sperm) never merge, instead only DNA of mother is used to produce offspring while the male contribution is effectively wasted (the science term is gynogenesis). Since the asexual females are stealing sperm that could make sexual fish, they act as so-called sexual parasites as they decrease the fitness of the sexual species they invade. In some species it even leads to arms races in recognition and "intelligence", pretty interesting... 😁

We know very little about the behavior of deep-sea animals. This can make them seem even more mysterious and even creepy. For example, some deep-sea fish have been known to emit bioluminescent flashes of light. The purpose of this behavior is unknown, but it has led to speculation that these fish may use their light to communicate with each other or to attract prey.

[@nobodyspecial6267]

You answered your own question, what else could it be for?

[@richt7525]

@@nobodyspecial6267 so many reasons, actually. Examples of complex bioluminescence in marine animals range anywhere from distractionary escape tactics to reproductive attraction and prey luring. There's a lot of other functions in the middle, as well. More research is needed, and we're finally getting the opportunity due to AUV technology.

[@billc.4584]

Or to advertise to potential mates that they're open for business or possibly as a defensive technique to startle potential predators. The bio luminescent may serve several purposes simultaneously. It certainly serves some important purpose(s) due to its commonality. My money would be on it benefiting reproduction somehow whether through identifying partners; making them uber-attractive to the opposite sex; or enabling them to not become something else's diner.

What's extremely interesting is to see and understand how scientists are able to capture these creatures and analyse their light-making abilities. Thanks to that, we were able to understand the three reasons why these creatures use bioluminescence.

Octopus Lady made a great video on this, but to get a 40ft squid fully in frame, the ROV would have had to be incredibly far away and thus its current wouldn't affect it. Plus, the squid was retracting its filaments which isn't something we've seen in confirmed video of ROVs interfering with magnapinna.

This video had me hooked. Your voice is so soothing to listen to I love it

[@ChronoMune]

Watching this made me think about how there are so many different worlds in the universe of all different sizes, separated from each other in ways but all connected. Not only in terms of anything beyond earth and how we’re actually so tiny in our whole planet, but even something like the microscopic world of germs and how in the same idea as this video, there are entire “creatures” within that world unknown to us (unless you study those things of course lol). Yet they have their own world they live and thrive in. The entirety of existence is so far beyond our limited knowledge.

[@Herio7]

If deep ocean is home for such weird yet amazing creatures imagine what astonishing animals could have evolved if we had more of such extreme environments.

[@Morgoth__Bauglir]

Nice pfp btw

[@BubbleBunnyy]

Tbh we have lots of weird creatures up here it’s not not weird because we are used to them, and dinosaurs used to exist like that’s crazy. Look at giraffes those are some weird animals when you think about it

[@connorjohnson4402]

10:40 the comparison is to a proud human who never look down haha. Most of humans have more than 100 degree vision down to up

[@danirfan5452]

Yeh humans have a verticle fov of 200 degrees I’m not sure what was meant by that

[@euph0r1k61]

I saw the diagram and I was like, something’s missing here haha. Glad I’m not the only one who noticed

[@KhushiSharma-rl3ly]

imagine being a squid who got lost and went a bit lower than it’s supposed to and the scientists said this guy is one of its kind. the only one found under 6000 meters.

[@johnnychopping3655]

Gets even scarier when you realise there are Colossal Squid down there too, and nobody even knows how big they truly are...

[@c.w.8200]

I read a magazine story about these as a child and I've been obsessed with the deep sea ever since, I fall asleep every night by imagining I sink to the bottom of the Mariana trench.

[@SilveniumTheDrifter]

Me, too. I wear a CPAP and always pretend that it's part of a "magical" diving suit in that the gas mixture stays constant at what I need it to be to survive, it's pressurised enough to keep me alive but be able to move relatively easily, and have "limitless" air. It helps to take away any "legitimate" death scenarios in my head that would rouse me from going or getting to sleep.

[@connorjohnson4402]

You mustt be sinking pretty fast in you imagination then cause it really would take almost your entire nights sleep to actually sink down to the bottom in reality lol. They also live stream deep sea ROV dives on youtube if you weren't aware look up the Schmidt ocean institute, Nautilius, and the oceans explorer, its just about getting to dive season so could be in the water soon

[@livenandlove1980]

This channel is both fascinating and soothing.

[@beyondfossil]

That "barrel eye" fish at 9:45 is an amazing feat of bio-engineering and evolution. Seems like an overly complicated solution though just to see directly upwards. Why didn't it evolve the behavior to float upright if viewing upwards was so important? So much more simpler. 🤔

[@ssrs8091]

could be to not spook its prey, or to save energy

@9:38 I thought I was looking at some computer rendering where the head was made transparent for the viewer to see the internal organs better. Nope, that's literally how it looks.

Fascinating video, and lovely footage! I remember that when I was very young, I had a nice colorful catalogue of sea life. It was in foreign language (arabian) so all I could get of it were the pictures (actually, very detailed drawings), which were really nice and interesting. There was an example of anglerfish and it was one of my faourite pages of this book - the anglerfish looked so unreal and scary, yet it was drawn in extremely realistic way. Since there was no size comparison shown (probably it was just described), I was absolutely sure that such a terrifying creature must be really huge - like a whale or so. I remember how shocked I was, when 20 years later I happened to see some BBC documentary and discovered that these creatures are quite small 😂 Thanks for this video, have a fantastic day! ♥

[@reda29100]

12:45 I have to disagree with commentator. I don't know if they see the camera and lights shun on them, but their look and them seemingly stopping observing whatever recording equipment they are curious about, spells cute and beautiful to me

[@Matthew-Anthony]

You should do a video on what animals do and how they reacted to massive sunken ships. I already know that aircraft carriers can be sunken to become reefs. However, there are a lot of other ships at the bottom of the ocean too.

[@jongeduard]

What I find great is that due to that submersible crash and the entire world getting crazilly obsessed with that, at least a lot more people seem to have more attention to the deep sea, finally. Would be great if more people started respecting the oceans of our planet. Because so much needs to change in our behaviour.

Truly mesmerizing! The ocean, and any body of water for that matter, both entrances and frightens me. For such life to exist and yet we know so little about it…the more I think of this, the more I come to believe that we humans are the “aliens” and we’ve just been visiting this body of rock and water; we’re hurtling through the universe at an unfathomable speed which isn’t even the size of an atom compared to the inconceivable size of the universe.

"Why humans get weirder the more surface they are?"

[@k.l.manring2083]

WOW!!! Thank you so much! I actually didn't know about many of these animals. Subscribed!

[@k29king1]

I kind if knew the minute the sub was reported missing that it imploded, while cautiously and optimistically hoping I was wrong. Then it was reported debris was found, but they were still talking about how much oxygen they had left, and that it was possible to find them. But I knew then that it imploded. Going down to that depth is like the trash compacter from Star Wars and doing so in a tin can pressurized from the inside. The pressure would always win out, especially in a highly improvised submersible. It was like a car crusher, crushing a stuffed animal. The only positive about the event was that all five aboard were completely unaware they were dying as it all happened so fast their brains hadn’t even computed what was going on. They were instantly snapped out of existence. If there is ever a way to go, this was it, painlessly and obliviously.

I read a comment online that said they would have heard the carbon fiber starting to crack and fail. This is why they were ascending at the time of the implosion

does this mean the deeper you go, the more politicians you'll see?
