No. Look at extreme examples. Finding out there's a lottery vs winning the lottery. Making home made cookies that taste odd vs making the perfect batch.
Gotta say, I was definitely not expecting to hear "ANCHOVY SEX" this early in my morning.... and I also think it's absolutely wild that anchovy eggs develop in SIXTY HOURS?!??! Talk about life on the fast track??? I didn't think any macro-sized organisms could develop that fast!
@@SaruCharmed Nope! I've seen the American version, which doesn't involve any fish, but I do know of the "actual" version, and also the Nicoise salad. Just never tried them. I might go look for anchovy filets soon though!
@@Beryllahawk Even in America, the dressing is made with anchovies. I think most people who have them don't even realize they're eating fish. It doesn't taste fishy, just salty.
Fun Fact: When Hank said that the early relatives of the anchovies had saber tooth, he referred to the Saber-Toothed Salmon, which was quite large, **and yes, everything in the Ice Age had to have huge teeth and ivories totally not to dig up stuff or use em as knifes :]**
Since i have consorted with sabre tooth kitties of up to 30 million years of age, may i suggest that your presumption of ivory tickling's limited existential span, similarly to pretensions of many youtube commenters on music, may be woefully limited.
Unless spelled out: Seizure Salad? or Seize Your Salad? Quite different outcomes among the illiterati. Spelled out, we DO retain some difficulty in discerning whether Dog Whisperer, or some "I et, too, Brute" composed or consumed salad.
I actually shouted "What?!" when the Bizarre Beast's name was revealed - I was not expecting that all! A very good video about a bizarre scientific theory that I would have never guessed in a million years!
The thought that this is how the ocean mixes makes makes the implications of overfishing and habitat loss even more terrifying than usual. And here I was hoping it was geothermal or hydrothermal vents 🤦🏽
This IS going to be one of the best pins you've ever made. It will have such a place of honor on my ocean pin banner, amongst the sharks and kelp pins, and of course, my favorite of all time -- the Bizarre Beasts hagfish pin.
The fact that ice floats means there's convection even when the heat source is from above. The temperature cannot stratify when the coldest part is forced on top.
Let's not forget that there IS a significant source of heat energy at the bottom of the ocean - geothermal vents. I'm going to give the benefit of the doubt and assume that this was taken into account in modeling because it seems too obvious to miss.
There are plenty of people taking thermal vents into account, but iirc they're not a significant source of mixing globally (I would guess just because there aren't enough of them, not quite my area). It's actually been proven since Sandström that you don't need the heat source to be below the cooling to achieve convection anyway
@@LuisAldamiz Google "map of geothermal undersea vents for the fastest proof of how wrong you are. Not to be a tool, but that was just very wrong. They are literally everywhere there is a fault line at sea, which is all around the world, and MANY of them are quite close to shore.
@@WrenStuart-y9h There are over 500 KNOWN vent fields, each with many many vents spread over hundreds of miles. But they absolutely ARE a significant convection source anywhere they are. Most of them were discovered because of the large plume of warm water they sent toward the surface. Can you cite a source that says they are not a significant source of mixing? Not my field either, but that is truly counterintuitive. If you've ever seen one in action in person, just one vent in a field can be sending tens of thousands of gallons a minute from the floor to the surface...... but that's less significant than fish swimming up and down a few meters at a time?
@@backpacker3421 - I did search for those maps (Startpage rather than Google, I've been trying to de-Googleize for very long now) and they totally confirm my previous beliefs: hydrothermal vents are along the mid-Atlantic ridge (the "wound" as Afro-Eurasia and America(s) pull apart from each other) and NOT near the coasts.
nothing - and i mean NOTHING - prepared me for the reveal at 0:49 Hank really said "anchovy sex" with such strong, consummate professionalism i had to pause and let it echo in my brain
It seems to me that every creature in the ocean would help to do the mixing, with some doing more work than others. The ocean has a lot of thermal vents that create the convection from the bottom that helps to mix things. The salt content may also be a factor for mixing things, different densities different movement. All in all I think its the entire biodiversity of the ocean along with tectonic shifts under it and of course the tides that gives us our beautiful oceans instead of giant lakes of stagnant water. And that, my friends, is a very good thing!
I haven’t heard thee expression for “It” as “doing it” for a very long time. That was a clean way to say “it” back-in the day and everyone knew what you meant. I said it quite often . Thanks for letting know I can still use it for “It” 😂
I thought anchovies were vegetables when I was a kid. I know they're not, but my brain always autocorrects when I hear the word. So vegetables mixing the ocean.
Gotta remember, different species spawn at different times of the year and different locations, so even if the anchovies alone dont explain how it works globally, it's a new route to look for.
Shout out to anchovies. I love anchovies, sardines, and all types of canned seafood. A lot of people think they’re gross but that just means more for me!
Pls, do one about the sea bunny. 🙏 I know you did one about the leaf sea sheep, but it is sooo cute and "fuzzy". ❤❤❤🐰 I think people would also love it.
I'm doing phd at the place where the study was conducted (very unrelated topic) and I had no idea this happened! I´m gonna have to go pester some people at the institute
It'd be nice to quantify how much energy is needed to make for mixing in the ocean. Upwelling and under volcanoes should be bigger contributors to mixing?
my theory on chins is just our teeth being so sunken into our face but the rest of the face did not keep up, sort of like our nose is part of a muzzle that did not get shorter in length and just had to curve along being pulled by our jaws inwards, there is no reason to really evolve away a chin so it stays there its also as a expressive and acts as more protection for our teeth it takes the hit, it also makes beards look bigger due to the curved surface angle
Out of curiosity, wouldn't "...energy was lost as heat before moving much water" contribute to convection currents? I know it takes a considerable amount of energy to warm up water, but could even those small amounts meaningfully contribute?
They had ONE fang back in the day?!? I need to know more about this! *runs to internet* Asymmetrical animals are so fun. You should look up huia birds (well you can’t since they’re extinct, but very cool flappers)
I'm surprised we didn't talk about like... the rotation of the earth, or the constant movement of the tectonic plates. It seems to me that new materual coming up out of a fault is Quite Hot and shock cooled upon contact. The substrait beneath the water itself is constantly edging along microns at a time. I imagine that's gotta send some energy into the water that causes churn. I'm not saying the anchoveys don't help, I'm just surprised that in looking for the cause of motion for a large mass of water, we don't look at the proverbial container its sitting in and what forces its contributing from below. Like... idk, the kinetic energy from the entire mass of the planet spinning?
Fish are efficient swimmers, they don't want to affect the water much, they want to use as little energy as possible to move through it. Look up "salt oscillator". Quite a lot of mixing is due to salt, which is very important as Greenland melts and makes the water more fresh, it's messing with the mixing. Also marine snow might drive some convection
But they can't help it: water is a very dense material which has to be displaced (as efficiently as possible but still needs displacement) as you (or your pet anchovy) swims.
When i first heard about this problem, my immediate reaction was "well, animals exist, surely that should play some part in mixing". Was not expecting specifically mating to be the answer xD
My question is, ocean predating complex life on earth, was the ocean still then or having more distinct layers ? And is it necessary in this case to have relatively still oceans to see life develop in a meaningful way?
It sould be due to the daily migration of tiny creatures coming up from the deep at night and returning to the deep in the morning. Oh, you cover that ((Diel Vertical Migration). The collective effect on ocean mixing of all sea life practiing the DVM is reminiscent of humans' collective effect on the world climate as a result of our daily actions, especially those involving fossil fuels.
*Why do scientists insist on narrowing things down to just one cause for everything? Reality is rarely that simple.* To me, what makes the most sense would be just the fact that there are SO MANY living things in the ocean, with their own cyclical routes that they travel. I think it’s safe to assume that would mix things up pretty good.
They haven't. They're pointing at what makes the difference between calculation and observed effect, and anchovies are just the biggest effect of fish movement.
@@thekaxmax Pretty much, but more that anchovies are a far bigger effect than they expected rather than the biggest effect. In turbulent mixing, you can calculate something called the "mixing efficiency", which tells you what percentage of energy expended goes into mixing water up vs. how much is dissipated by viscous friction. The reason that biomixing has largely been discounted up until now is that the mixing efficiency for fish is usually very low, we're talking below 1%. Compare this to the the ~20% efficiency typical for pure physical processes like wave breaking and you can see why biomixing was largely ignored up until now. What was so surprising about the anchovies was that the way they were swimming had unexpectedly high efficiency, which has brought the question back to the forefront of science.
@@Lolibeth or maybe you could try your comment again, but with a little more empathy. I wrote my comment at the start of the video, when the introduction was giving me the impression that this would be **yet another** science “mystery” video that seems to be seeking a single solution to a clearly multi-faceted problem. I could go back & either edit or delete it, now that I’ve seen the whole thing, but I’d rather leave everything intact so that others can see how rude & mean-spirited you are
"Lost as heat..." so even if the motion of swimming is diminished, they are still warming the water around them, warmth that can help convection. Just saying, it's not usually just one thing, but a combination of things.
I mean, I would also assume that the constant movement of the animals in the ocean as well as things like thermal vents... anchovy sex wasn't what I had in mind, but it will now be a permanent scar on my psyche
Munk has had a taste of what Schrodinger’s cat went through, though his intention was humor as opposed to Schrodinger‘s mockery of what he’d thought to be a ridiculous concept
For those who may never havr swam (swum, i believe is the correct participle, or whatever, but i've never heard anyone use it) just above thermoclines, especially wearing fins, biomixing can become very clear - just pass again over areas you have disturbed, and shiver at the no longer warm changes . When one sees a relatively nearby giant whale breaching half its body from the water, you also get a sense of concentrated biomixing, if isolated. Due to the immensity of human destruction in US waters, and certainly the crazed tropical overfishing, you may also have never experienced the vast, racing, exploding shoals of small fish followed by cetaceans and other large predatory species, with attendant clouds of birds so thick, tht you cannot see brightly colored sails of fellow windsurfers only a few hundred yards away. While i have difficulty controlling my nausea at human and freeway densities, whether favelas or unrelieved buildings from a local elevated viewpoint, such truly rich sights as i described are awe-inspiring. I recommend your support for legal birth control. You also might just learn to prefer diverse biomixing, rather than COVID.
interesting... so our over fishing is (jsut fishing in general IMO) is an energy drain in ALL ways. .. great(/s) how do we get more people to change their world views. to get a better, earth based paradigm? i'll even concede that an earth based paradigm is discriminatory to the our solar system, and other solar systems and ultimately the universe and any other universes... because if we can't even care about one planet i dont see the general public being concerned with damaging the fabric of space time with warp fields . ( sci-fi, but the fact that we have thought of these stories already, as analogy for burning fuels... is a huge concern in reality. it is the forward thinking we really need )

I recommend your support for legal birth control. You also might just learn to prefer diverse biomixing, rather than COVID.
Lantern fish tho. They ascend and descend every day. And they're so abundant that they initially altered ocean floor readings.
No matter what we breed we’re still made of seed.
What is the difference between anchovies and sardines? I always mix the two
Would heat vents and such not help contribute at all?
How about under water volcanoes of witch number in the thousands?
Not in those locations. Know your planet, Earthling.
Only thousands-- they are a tiny part of the sea bottom. And were included in the study
underwater volcanoes pale in comparison to how big the oceans are
People will never look at pizza the same way again.
New pick-up line for the sexy science nerds: "honey, our love making will be worthy of the anchovies: powerful enough to stirr up the oceans!"
interesting... so our over fishing is (jsut fishing in general IMO) is an energy drain in ALL ways. .. great(/s)
how do we get more people to change their world views. to get a better, earth based paradigm? i'll even concede that an earth based paradigm is discriminatory to the our solar system, and other solar systems and ultimately the universe and any other universes... because if we can't even care about one planet i dont see the general public being concerned with damaging the fabric of space time with warp fields .
( sci-fi, but the fact that we have thought of these stories already, as analogy for burning fuels... is a huge concern in reality. it is the forward thinking we really need )
