So you're telling me this fish drowns .
I... hadn't thought of it that way. You might be right.
Technically humans (and all creatures with lungs) drown because we can't extract enough oxygen from water, not that we can't breath water. It's just too inefficient.
Sharks can drown and they are fish
@@webchimp Technically not, the issue is that the density of water makes it impossible to breath. That meaning, our lungs doesn't have the capacity to keep the fluid exchange as with air, hence, even if we could extract O2 from water, we couldn't renovate the fluid. That is one issue with the oxygenated fluids that are being around, works in small animals, not so much when you gulp litres of it.
@@Sfaegbe not all sharks though, just the ones that cant open and close their gills like fish can
"Man this water is filthy. I need some air...Man this air is polluted. I need some water...
And thus began the teeter totter life of the Arapaima.
You really know where's the gold of comedy is
Arapaima é o k7 esse é o Pirarucu seus peba
😆
@@JoaoPauloSSilva-dw1vz kk
Oh really fish starts breathing on carbon dioxide 🤔
Ive always dreamt of milking a fish
Yo come to Brazil, we have many abandoned drug dens for you to wreck here c:
Sip milk from the fish head nourish yourself
Tyrion Lannister: "Milk my eel"
You got weird dreams man
Of course you'd be here
All the best milks come from skull orifices.
Oh yeah ( ͡° ͜ʖ ͡°)
I've got no idea what you're talking about. Would love an explanation.
😂 Since when are you a biologist?
You...you good bro?
@@walangchahangyelingden8252 in the video, the fish produces milk from its skull orifices.
This fish: Stand aside Anacondas and Piranhas, there's a new sheriff in town.
Humans: Ah yes, dinner’s ready.
OnLy TeN dAyS frOM rEtieREmEnT
Dinner, as long as it dont jump at ya
Haven't arapaima been around much longer than both anacondas and piranhas?
@@steveno2760 yes i believe so
It taste like salmon, delicious. My uncle have a fishfarm of arapaima (pirarucu) in Minas Gerais
Real Science: *mentions arapaima*
Jeremy Wade: *PTSD intensifies*
I'm not the only one here!
pls tell me what happened
@@bababistril big man Jimmy here was in a lake or something with a bunch of local doods netting in some pampams when the fishy fishy go fly fly because they can and since the milker water dweller is the size of my mom one birdwannabe just rammed straight into Wadey boi's chest and he cannot breath normally since
@@UncleRJ can you read me bedtime stories in this style ? I can't stop laughing xD
One of the first fish Jeremy caught on the show.
Fish that make milk is a sentence that not many have never heard before.
And I just found the cows of the seas lol
when I did read it I was like:
I hope nobody will try milking that fish
Yeah me neither.
if we consider tetrapods (including humans) as fish then it wouldn't surprise us as much
Have you ever heard the tragedy of a fish that make milk ? I thought you not. It's not a story a farmer would tell you.
An interesting (and sad) fact: the range of the species used to be much bigger. Today, it's possible to find small populations in the Tocantins-Araguaia basin, hundreds of kilometers away from the Amazon basin. A few decades ago, it was quite common to spot them even in some smaller Araguaia river tributaries. My grandfather, who spent most of his youth as a poor farmer in the state of Goiás, tells stories about how they used to catch the Pirarucu (this is how we call the Arapaima in most regions of Brazil) only to use its fat as traditional medicine.
Wow, pirarucu down in Goiás? Such a sad state of affairs to see what we did to our nature...
PIRARUCU!!!!
Tem pirarucu em minas, mas é introduzido. As vezes os de Goiás também eram
@@ramon-theyseemerollintheyh1982 pode ser
There must've been hundreds of thousands of these fish killed since he was young though. By the time you're a grandpa, they'll be extinct
Loved the fact of how the researchers managed to make a solution that benefits natives, tourists, and the large fish and there offspring.. without a negative drawback for all parties involved.
Wow. I'm brazilian and I've never listened something about this of this fish. Here, this fish is very famous for its size, but sadly no one knows more about it
Brasileiros comem este peixe?
Pirarucu
@@bri1085 Eu como com açai.
@@bri1085 sim
@@bi7m Não sei o que é açai, Eu vivo longe do Brasil. Só sei as frutas basicas, maçãs, laranjas, bananas.
Loved the episode. Also ty for putting more emphasive how humans are able to help the fish, not just how they are doing bad for the fish. They often do that in documenteries and gives a depressing after taste. Your way of talking about the subject makes you more hopefull and gives insight on how you can help the fish and river
Nice opinion 😘
Yes let's keep it positive like a fantasy , pesky reality is so annoying every time you think you can pat yourself on the back . You find out your species is a feral pest destroying everything in sight , but their is always hope , the remedy of wishful thinking .
But she did mention all of the positives that have been happening though. She even outlined the different ways the communities are undertaking to increase the population of Arapaima.
@ytkhunter Indeed. Always good to highlight the positives humans can and are doing to solve problems, especially to solve the problems humans themselves created. Without that, we end up with people like @romanbrandle319 who struggle to see beyond all the negatives to recognise the positive changes.
What an amazing and unusual species, and an extremely well done video!
ARRIVAL , I also like that movie
I have ate one the fish's or speces of it it is found in India west bengal and bangladesh
Meant to be going to bed and I’m learning about fish milk
Wait, is nobody going to talk about how fishes can breath air in, and fart it out.
Hahaha
It is really impressive.
Betta fish also have the adaptation to breath air as a complementary way to get oxygen
Burp it out*
Not only this big boy can.
Once my koi fart out a big bubble my arowana suddenly swallow that fart in
Once whilst dating a Chinese girl her family came to visit here in Australia, we all went to the Aquarium together, as we walked around the aquarium looking at all the beautiful and rare fish, her father, a successful importer/exporter from Singapore, kept excitedly going 'I've eaten that one, and that one, oh and that one there too!'
You could sell nail clippings and pass them off as pengolin powder 😂

Everytime I learn about an amazing animal, I also learn that they're endangered
Technically, they aren’t endangered. TECHNICALLY they are listed as “Data Deficient” by the Red List. This status hasn’t been undated in over 20 years! How lovely and amazing!
Yeah. I’m mad about this.
There is an amazing animal who's far for being endangered: human
@@BorisKOUKAHumans are anything but amazing.
Fish in the genus Symphysodon, commonly known as discus fish and also originating from the Amazon region, exhibit very similar brood care with releasing a milk-like liquid for their fry. Unlike in the case of Arapaima, the 'milk' of Symphysodon does seem to provide the young with nutrition.
Wow they’re almost mammals
"Most fish simply lay their eggs and then bounce."
This is Sparta?
...?
Arapaima Milk - coming to a "health" food store near you
Yeah can't be endangered if we farm the milk
It's really upsetting that we could be the end of an awesome fish like that.
23 million years...
we have a knack for doing that lol. maybe in the future we can use DNA samples to bring back some of the ice age mega fauna we helped drive to extinction long ago.
@@kevinmathewson4272 I don't think bringing mega fauna is a good idea, we don't have many places where they can live naturally but we can take care of what we have and not drive more creature to extinction
@@alexalfonso100 yeah that's probably the mature view. the kid in me just wants to see a giant sloth
@@kevinmathewson4272 ok fine then, but only one...and we can take turns riding it...
they're invasive in other areas so they definitely aren't going extinct everywhere. they have taken over in Bolivia.
Good episode. The narration is perfect- not anxious, too fast... and it doesn’t tell me how AMAZING and INCREDIBLE they are. I’m able to draw that conclusion myself. I mean, it is a fish with milk.
You choose good topics. Keep letting them do the work :)
There's one video clip here in the Philippines about a pet owner and his only pet, which, of course, is an arapaima; that he took care of his whole life in his backyard-turned-fishpond, but sadly passed away.
Someone volunteered to preserve the fish's remains and the owner agreed, to be made as a display piece (a big one) but I don't know what came of it.
Needless to say, that's a big pet he's proud of.
this feels like a transitional species to another group of fish moving to the land and tbh i think thatd be so cool
But can we milk them?
I’ve loved arapaimas since the elementary days. Never knew they produced milk though!
They don't say mooo thought....
Arapaima... But my friends call me Pirarucu 🇧🇷
❤️
These are cool fish and I'm stoked to see someone making shows to spread awareness about them
There are a few freshwater fishes larger than arripima, such as the pariba, an Amazonian catfish that can grow upwards of 3 meteres (google says 3.6 meters), or sturgons, I believe the white sturgon can grow near 16 feet, and the beluga sturgeon are even larger. Alligator gar can grow around 3 meteres as well.
Sturgeon live a good part of their lives in the ocean, arapaimas live their whole life in fresh wather, bout you are right, beluga sturgeon get a lot bigger then arapaima
Thank you for using the metric system!
I was expecting for you to say that the arapaima can weigh up to 200 lbs
finally
Finally
Metric system
I actually didn't know it was also called Arapaima. I'm Brazilian, but I've always known it as "Pirarucu", which in Tupi means "red fish". Great video btw! 👏🏻
Yeah for some reason the rest of the world calls it Arapaima, which is barely used in Brazil as I understand. It’s weird
Just found your channel and after watching several of your videos I felt I had to say thank you to you and your team for the quality content. Each piece I have seen is exceptionally fascinating and provides an incredible resource for their respective topics. The information feels thoroughly researched and the passion you have for each subject really comes through in your script and narration. The stock of footage and accompanying diagrams is exceptional as well, making for a truly delightful viewing experience. I also very much appreciate the detail of supplementary information explored in each video concerning how and why certain traits may have formed, and what significance they have compared to the broader spectrum of evolution, or how such adaptations can have applications in human endeavors. I know an enormous amount of work must go into making each of these videos, so thank you again so much for the effort put into spreading the knowledge and awareness of these and other incredible creatures, and the passion in which you do so.
Great channel. I am so happy I found you. I will add this to my marine science curriculum
Not necessarily most fish spawn and dump, many fish are incredible parents, like most of the Cichlid family. Also, fish like the Uaru and discus produce milk for their young.
Really liked this one! Thanks for sharing
This was a very good and informative video. Really amazed to know about this fish 🐟
Fantastic video! It really warmed my heart to know that with regulations on fishing, the populations bounced back massively.
One thing I should add though is that Arapaima are not the largest freshwater fish. They make top 10, maybe top 5, but the number 1 spot goes to the Beluga sturgeon.
So is it evolving into a mammal.
No, I get the reason why you say it but that's not gonna that big of an indication that they are.
The fact that I rooted for the fish at the near ends really tells something about me
Arapaima: "I am the milkman, my milk is delicious!"
Loving the episode,Thank you
If there's a Malaysian watching this, there's a couple of Arapaima in one of the lakes in FRIM. It's difficult to see them properly since it's a murky lake but when they come up to breathe you can see enough to make them out.
I've actually learned something new. Thanks a lot
Arapaima actually became pets in Southeast Asia especially Malaysia Singapore....... A fish symbolic "Luck" and it could sell at a crazy high price over USD10K if the colour and shape are "right"......
Interestingly, the teleost swim bladder did in fact evolve from the primitive lung, so the two are in fact analogous. The lineage that went on to become tetrapods developed it to be a much more efficient lung, whereas in the ancestors of bony fish it turned into a buoyancy control organ. Those fish that still use their swim bladders to absorb oxygen are amongst some of the most primitive surviving lineages of modern fish. They have retained this ability from their ancestors, rather than evolve it as a new adaptation, whereas most species of fish have lost it.
12:15 Holy shit that was like watching a cow do show jumping. Wtffff
10/10 video. Well written, researched, edited, narrated, and full of interesting tidbits of information! *subscribes to Real Science*
That thumbnail is a true gem.

Why fishes eye have that same pic on your profile?
Thank you. For this video. It was. Very interesting. And well made.
Thank you! Great information and study!
Amazing job with the videos! They are unique, informative and well done!
A magnificent channel, continue sharing such a informative content.👍🇩🇿🇩🇿🇩🇿
Amazing content I`ve been binge watching episodes
you put together a brilliant platform for education and jaw dropping facts
I`m looking forward to more videos in 2022
Have a great New Year !
I believe (though I may be wrong) that aripima are farmed for the commercialy and that fishing for wild arripima for the market is illegal in some parts of brazil.
If I make a stew with this fish, the stew essentially becomes cereal?
depends
This was a truly mesmerizing piece of new knowledge. Now on to fix my car.
The ones that aren't catadromous are small fish . The arapaima are one of at least 7 species of fish whose introduction could allow the processing plant to open back up. Plus their introduction would increase the sporting opportunities for fishing tourism.
Great source of knowledge...thank you
A certain shark would like some of that milk.
I loved them already but now, wow! I love them more ❤️
Thanks for all the awesome information 🥰🇦🇺
Your channel is so necessary.
There so nice animals in the World,lots of perplex dont know. This Video was structured so well.
Excellent video ! Very well done .
OK, I think I have my new favorite fish!!
Very well made video an very informative. I do hope they succeed in creating a wildlife sanctuary there, it's a steap in the right direction. The world's waters fresh/salt *need* all the help it can get.
Thay was a really interesting video, well done
12:16 jesus that dude almost took a 200 lb missle straight to the dome
These are not the largest freshwater fish in the world, multiple species of sturgeon, paddlefish, and maybe even catfish are larger. They're on the list, but not the top
I mad similar comment, pariba are larger and live in the same river, and the beluga sturgeon of Russia can grow up to 20 feet long.
@@epauletshark3793 sturgeons aren’t completely freshwater though
me watching: *Terraria war flashback*
Very Interesting. Thank you!
The fishing tours are like “pay us to let you traumatise these fish we’re keeping safe”
Nice to hear something about the Arapaima, fascinating fellas...
Other fact
In Indonesia, this fish are introduced as an Aquarium fish, but they are released to the wild, and Arapaima Gigas are listed in 152 banned fish species in Indonesia
5:00 did they just call caiman "amazonian alligator"?
RITVIK MENON i know, that’s what i’m saying. It’s like calling jaguar “amazonian leopard” frankly i find their word choice on this a bit weird
I think I remember the Aquarium of the Americas in NOLA having one of these in the 90’s. I had misremembered it as an Arrowana.
Protect all ecosystems that include deserts and forests, wetlands and in-between
desertification is literally a big problem. Deserts should be smaller than they are
@@carlosandleon natural deserts needs to be protected, and man made ones needs to be restored to what it was before. I know that you mean well, by informing people about land degradation, but that doesn’t mean deserts isn’t worth protecting (it still play a role in the biosphere). I fear that some people might take this literally and start reforesting a native desert (with no prior knowledge of ecology), and destroy local biodiversity. Cause i’ve seen people trying to help nature by placing invasive earthworms in temperate forest, not realizing that they are altering the soil makeup and put the whole ecosystem in danger.
@@anonymouswhite7957 the natural deserts are expanding. Deserts have their place, but not to this extent.
I've heard some humans (depending on whether they carry a gene variant) produce two types of milk, first a milk called colostrum that is similar to the milk of these fish that contains immune compounds, and then the regular type of milk that is mostly nutritional content.
Jip it's sticky.
Arapaima is such a cool looking fish in general, they also have really pretty colors.
I love these creative protection ways
Arapaima: *makes milk
Milk fish (has milk colored meat): "Am I a joke to you?"
"Arapaima"
*proceeds to have hardmode jungle flashbacks*
Thanks for reminding me to watch my CuriosityStream videos... gettin' old and forgetful. It's only $15-ish/yr and comes with Nebula.
The vid she talks about at the end, "Amazon River Islands; The Floating Forest" is a part of the "Wildest Islands" series. It's also available to Amazon Prime members (altho they recently added damn commercials, grrrrr!).
I would love to see video of them feeding their young!!
Quality content right here gents!
"the fish's skin, called leather..."
ok
I had to rewind just to make sure I heard that sentence correctly. 🙃
Animal Crossing didn't teach me about this...
It's called "Pirarucu" here in Brazil
Here in Brazil we call them pirarucu,which means red fish in some indigenous language that I don't know the name
And sorry for the bad English lol
Yup it taste so good too!
Let's not forget that discus fish and some other south american cichlids can produce this so called "milk". As a colombian guy, I feel so lucky to have them locally. Peace!
Parallel evolution but the discus species of ciclids also provide skin milk to their fry. I've not kept discuss, they are supposed to be fussy in their required care but now I'm curious about whether they surface for air too.
Thank you Real Science for highlighting this amazing fish.
I liked the explanation about the different types of swim bladders and the structure of the scales.
A few mistakes were made though :
0:20 Arapaima gigas is not the largest freshwater fish in the world. The title belongs to the Beluga Sturgeon (Huso huso) which can exceed 6m.
0:23 Arapaima doesn't generally grow to be 3m long. In fact, they rarely exceed 2.6m (the record was 3.07m).
5:07 Amazonian alligators are called Caimans. Yes they're part of the Alligatoridae family but they're still called caimans, not gators.
Mammals: we are the only animals that produce milk!
Arapaima: hold my beer.
*hold my non-mammalian milk
Pigeons and flamingos also make "milk".
@@skippy9214 non-milk
Flamingos and pigeons too
Mammals were defined by the ability to produce milk
I'm sorry, what?
Outstanding video! Brava!
Curiosity stream + Nebula, NICE!
Infact there are other fishes that make milk. Such as discus fish. Not like mammalians of course, it is secretion of mucus from skin full of proteins and antibodies.
What about discus fish, which come from the same region? It’s well-known among aquarium hobbyists that if you breed them you have to leave the fry with them for some time because they feed on the parents’ mucus.
I used to watch these fish at the Sheds Aquarium in Chicago.
They sure are smart to get all those adaptations. Totally doable
