How do the layers of the ocean mix together? The energy put in by the winds and tides is less than what’s required for the amount of mixing, so what else is bringing the mixing energy? Turns out, it might be very active anchovy reproduction.

I would argue that krill would still cause biomixing because of how many other creatures feed on them
"It’s not the size of the boat, it’s the motion of the ocean"
~ the Anchovies
That was funny, good one.
Hank saying "anchovy sex" right as I took my first bite of a Caesar Salad was perfect.
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 was eating chocolate chip waffles 😂
In front of your salad!?!
It's even funnier if you know that Ceasar dressing has anchovies in it... so I was literally eating them while watching this episode.
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!
Calling anchovies "macro-sized" is hyperbole on your side. But they're definitely macro in flavor.
@@LuisAldamiz They're not microscopic, was what I meant, haha. I don't think I've ever eaten them.
@@Beryllahawk Have you ever had a Caesar salad?
@@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.
Somewhere I read approx " the most exciting sound in science is not 'Eureka' but 'that's weird?' "
pretty you all just proved that.
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.
I've never seen an anchovy, i thought it was a weird vegetable people don't like on pizza. I didn't know it was a silvery European fish!
Check out the Cloudy with a chance of Meatballs movie lol there's a famous anchovy
But people *do* like it on pizza. We're just scared to say so in public because the haters are so militant.
@@tinkergnomad You haven't seen the futurama episode, have you?
I grew up watching spongebob and Futurama, so of course I know what anchovies are 😂
Wait till you see iceberg lettuce, it's gonna blow your mind. Spoiler * it's nothing to do with ice. 🤯
Hee hee, Instead of a butterfly-effect, it is the Fish-bone effect
Hee hee 😂
Michael?? Is that you Michael??
Blink twice if you need help
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.
Spanish researchers: Do you smell it? That smell. The kind of smelly smell. The kind of smelly smell that smells... smelly…
ANCHOVIES
Took too much scrolling to find this tbh
Spongebob reference? 👍🏻👍🏻👍🏻👍🏻
Call them anchoas, call them boquerones, all them will fall for the taste (they don't smell that much but the taste is very intense).
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!
Lol me too!
''K'nuckles! You're drinking the entire ocean! Stop it, don't you know what fishies do in there?!''

Season 0 was fun and necessary for factual accuracy reasons, but im glad were back to regular Bizarre Beasts, the production is pristine
I'm new to this channel. What's this mean?

It's either him or Simon whistler 😂 I'm not mad though!
My bad, I have bad form when swimming

That is some epically bad form their, my friend!
Yo mama so fat she dove in the ocean and now the layers are mixing
@@kurocknotabi 10/10 :D
"The physics of the ocean is about to get freaky"
Some Anchovies probably
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
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.
Not where the data was collected. Geothermal vents are in the mid-Atlantic Ocean ridge, i.e. between Iceland and Azores, not so close to the coasts.
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.
thats incredible. would never have thought such a small fish could have such a big impact
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.
My brain always thinks of green olives when i read anchovies
things were said in this video that kept having me thinking "well I didnt expect to hear that today... or ever"
Animals unintentionally maintaining their environment.

The opposite to humans
This is hilarious and indeed bizarre and you've significantly contributed to my mood. Thank you so much for that!
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.
I did not expect that reveal. I had to sit down from giggling too much
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!
Not at those locations.
I believe there are underwater currents too. And icebergs .
Step aside, Butterfly Effect. It's the Anchovy Effect's time to shine.
Poseidon, of course
Though his anchovies, of course.
@@thekaxmax Olympus works in mysterious ways
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 🤦🏽
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.
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” 😂
1:09 to 1:11 we all agree it’s so good
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.
I learn more from Hank Green than my Oceanography professors
Still the best video series on the internet. And the best day of the month. I truly love you guys.
The brine shrimp time lapse looks like a Van Gogh
We love you, Hank. We love you
Anything Hang Green - Never a disapointment. :)
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!
I subscribed to the pin club last month especially for the hyrax and i got the rare one with pink sparkles! i love hyraxes!!
As a commercial fisherman, all the fish in the ocean, stir the ocean just by swimming
I had this on my watch later playlist before you changed the title and thumbnail, so I had the question raised and answered before even watching it
Ruling out heat from below is a wild move. Especially with the extreme sea temp spike that can't be explained by greenhouse or solar activity.
Instant classic fish video 😄 right up there with the deep sea anglerfish
Just keep swimming... just keep swimming...
Or the ocean dies.
I'm watching this while eating a fish sandwich.
What a time to be alive.
I still love Hank's new hair - I know it came at a great cost but it rocks ❤
Thank you, anchovies. Keep mixing ... work and pleasure.
People will never look at pizza the same way again.
in the ocean streaight up "doing it." by "It" lets just say. My Chovies
Mixing it up and getting it on
The fish in your deepdish makes the motion in the ocean.
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

0:52 i almost choked on my food
Once again petitioning for an episode on flying squirrels!
So love really does make the -world- oceans go around.
WHOA, I was not expecting that right out of the gate! 😮
that was not in my mind when I opened my RUclips for tea today, but well...
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
This has serious ramifications for the Futurama universe.
This is a literal case of the butterfly effect
The anchovy effect
Its not. Butterfly effect is a different idea entirerly.
So... Zoidburg's people making them go Extinct would have messed up the oceans?
Now I'm going to feel guilty when I open a tin of anchovies for lunch.
5:10 the team had a what...
I'll see myself out
"It was a joke guys"
*Munk*
Anchovy paste adds depth of flavor to food.
Here is my comment for support
I feel like Hanks vibe is different in this video. I like it. Might be the curls.
At first the 'anchovy sex' was a bit funny..
Then after reading comments it was quite funny :D
Then i realized im currently eating fishsticks.
love that the anchovy pin doubles as a poly pin 😂
Uh-oh, guess no more anchovy pizzas, LOL! Seriously, that's totally cool!
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 agree
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
losing my mind at the image of a dead salmon in an mri
Anchovies? More like sea buffalo.
Then the Decapodians come and the anchovy mysteriously vanishes 👻
Ah humans... We ruin everything.
"We are the virus" mfs when a well executed prescribed burn walks into the room:
Hey Hank, as you mentioned SciShow: Eight days without new videos, what's up over there (or isn't)?
Love makes the world go around, for now at least.
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?
My favorite snack!
mmmmm......anchovies.......haughlaughlaughl
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
You guys should team up with strangest thing I learned this week.
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!"
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)
Fascinating. Anchovies are God... or at least Neptune. Let's not overfish them, OK?
Whoops, sorry about that. Accidentally sunk a boat full of immersion blenders

Me: Internet flashbacks ptsd
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
*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.
But, praphrasing Adams, "the Ocean is big very big, mindbogglingly big"...
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.
They're not. Watch again and try a little harder with the comprehension.
@@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
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
You should ask how are we fixing the dead zones fishing ships have made
Lantern fish tho. They ascend and descend every day. And they're so abundant that they initially altered ocean floor readings.
Anchovies! Meep. Meep.
So what Hank is trying to say, it’s not the size of the animal. It’s the motion of the ocean.
The vortex has entered the chat
talk about the butterfly effect! I’ll never see anchovies the same again.
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?
Things like whale fall surely contribute, but not compared to this lol 💙
