- The crocodile icefish has clear blood, a genetic mutation that should have meant GAME OVER, but it didn't. It just happened in the right place at the right time.

So I wanted to see more footage from "Henry Kaiser" in the artic ocean, and I looked up "Henry Kaiser" and a bunch of guitar videos popped up. I thought "This must be the wrong Henry Kaiser." Turn out no, he's a guitarist AND he does artic diving. Cool guy.
sounds like something Henry Kaiser himself would say, Mr. KrazyKAISER 🧐
Please tell me the username is just a coincidence....
Great comment.
Nice shirt!😍
Hell yeah, he shreds and treads (arctic water)
I'm a big fan of Hank's shirt and this strange fish
My thoughts exactly 😁
Evolution is real > all races are equal.
@@ElectricalExistence what
@@Prophet_Isaiah think about it normie.
Electrical Existence English please
But so wait, does it still have erythrocytes or is it missing those too?
Edit: googled it, they sometimes (but rarely) have erythrocytes (aka red blood cells, but they're not actually red in this case), but they basically don't do anything. And some also don't have myoglobin, or at least not in all of their muscles, which is also crazy
lmfao
‘How are you still alive?’
‘I honestly don’t know’
Thank you for the knowledge sharing.
Sincerely,
Too lazy to Google
they would taste really weird.
@@officersoulknight6321 I mean the line between not alive and alive is fuzzy enough at the viral end of the debate. I'm sure it applies just as much to complex life missing what should be essential to maintaining life.
I feel bad that I’m too broke to get the pins but I love the content that you guys make! I really needed a shot of curiosity to get me away from... **gestures broadly**

Broadly?
lmaoa so true love the gesture
@@xploration1437 yes, gestures broadly at everything in their vicinity, and then some.
Essentially, Calgon take me away, escapism.
Ah bummers, so rising ocean temps will definitely affect these very unique critters very negatively.
f in the chat for the icefish
On a small up side, the coastal areas will become colder and snowier, helping to restore the range of moose on the east coast because more moss will grow in the spring.
😞
It is not going to be happening that fast. They are still in one of the coldest places in the planet so they probably would be able to adapt.
@@andresmarrero8666 Unlikely, even if the waters warm up just high enough to melt the ice it'll put them in competition with more red blooded fish and also would render their lack of hemoglobin a huge disadvantage in warmer waters.
In my intro college biology class, we learned that the icefish had the advantage of lower blood viscosity because it lacked hemoglobin.
Is that an advantage? Seems like it wouldn’t clot very easily. But does it need to be more slippery in order to squeeze whatever efficiency it can out of the oxygen inside it?
@@emilysmith2965A lower blood viscosity makes it easier for the heart to pump. This increases blood flow(at least in humans)
Maybe they don't have -platelets- thrombocytes, either? In their niche, it's be alive or be lunch, with not much in between.
They would require less iron as well.
Because of this adaptation if an icefish found itself in warmer waters, it would literally drown, not being able to extract enough oxygen from the water around it.
Are you sure the lack of haemoglobin isn't an advantage? The elimination of the need to produce red blood cells could have saved them a lot of energy and nutrients that could be used elsewhere.
It probably evens out since they need 4x more blood
@@devinnall2284 blood without haemoglobin is probably not much more than water, and it's a fish...
Presumably they wouldn't have ended up with "super low metabolic rates" (which I assume implies it's lower than the average for antarctic fish) if forgoing haemoglobin was a net energy gain.
@@asdu4412 forgoing the production of hemoglobin might be a way to reduce metabolism even more.
@@quitlife9279 even if makinv it is easier the energy required move 4× times the volume of blood aka heart beat and stroke volume would consume energy. So in the end i think ig maybe a bad adaptation or at least neutral.
Clear blood? Oh now that is cool!
one of the PBS Eons I think, had a video about the evolution of blood and brought up other things with non-red blood, I think one was even like a fuschia color or purplish.
Invisiblood
I will have to watch this again. I was just staring at Hank's shirt the whole time... So good (both the shirt and the video).
Two questions this doesn't answer:
-Why does it swim with it's tail bent sideways?
-Isn't it an obvious advantage to not require so much iron/hemoglobin? Iron is hard to get, for humans it may be what pushes us to eat meat, harder to catch than just eating plants. An maybe lack of iron allows lower metabolism?
I'm just guessing, but it seems like the discussion in the video isn't addressing these obvious questions.
I also wondered about the tail. As an aquarium keeper it's common knowledge that that exact look means the "fishkeeper" who took the photo in captivity had poor water quality with too high of nitrates over an extended portion of the fish's life and the chemical led to a deformation of the spine.
Hi, thats what I suspect as well. Iron is very rare in the southern ocean, as iron usually comes from terrestrial sources and there are just less landmasses in the southern hemisphere. In the Atlantic a lot of Iron gets blown in with winds from the Sahara. I now that a lot of species of Phytoplankton in the Antartic have very intersting adaptations to low Iron concentrations. As Iron is an essential part of hemoglobin, it would surly save a lot of Iron not toproduce it
So what you’re saying is it has ghost blood
That's gonna be the name of my band
@@troublewakingup I'll take 1% royalties for the idea :P
It's a Water/Ghost type Pokemon.

@@briannelson3830 Ice/Dragon - check out some of those names. Cryodraco Antarticus? Christ, what glorious nerd named that one?
Always a good day when one discovers *another* Hank Green channel!
Now we need a list of all the Hank Green channels so we can find and watch all of them, though I do quite like the surprise of unexpectedly and spontaneously coming across Hank Green on a new channel every now and then
@@Manj_J it's like finding another subreddit for cats.
When you find out Hank says “nit-ches” instead of “neesh-es”.
Well, nobody's perfect xD
reminds me of the incident with his presentation on the facade of buildings 😂
Although in this instance I think both "nit-ches" and "neesh-es" are considered correct whereas the same cannot be said for "fak-aad" and "fuh-saad"
@@emmao6578 I think in the US “nitches” is a common pronunciation
@@emmao6578 it's still saad 😆
Like it matters
I like the physical background. It feels much more "authentic" than the greenscreen
Imagine how a lamprey or hagfish would react if it attached to a clear-blooded fish.
What do you mean?
@@jesusdiedforyouproofjohn3.16 are you asking yourself?
evolution is just nature saying "I CAN BE WEIRDER THAN YOU!"

Guess I shouldn't complain that my blood made my face red due to the nip in the air on the way to get the mail this morning.
Rosy cheeks is a sign of good health, which is why rouge makeup exists.
I love that it combines two things I love - fish and ice. I just wish it had a cooler name... nvmnd, thought to look up the latin names of specific genera. Cryodraco is there.
They're just built different 🌟💕🧚♀️✨❤🌌
There is a great book, "The Making of the Fittest" by Sean B. Carrol, that has a chapter on the ice fish. If highly recommend it.
Why does their tail curl like that when they swim?
Funny how questions that you have turn out to have answers you haven't thought of the questions to. I knew ice fish could stand the cold because of the anti-freeze elements in their blood but I never knew that their clear blood held the secret to their success. Once again you have blown my mind and given me a renewed sense of wonder at evolution's ingenuity. You do this all the time and I can't thank you enough.
Amazing video as always, I'm always looking forward to these every month ! A true treat! Ii was talking to my partner all week about my guesses for this week's topic ! Of course I was wrong but you can't win if you don't play ;)
PS: Hank, I love your shirt !
This just kept blowing my mind every time you stated a new fact.
I've heard of red blood, and I was stumped by blue blood, and I NEVER EVER heard of different colors of blood. There's always something to learn.
Once upon a time,
It was the end of Eons,
A great link happened,
And now I am here.

RUclips does not like this channel. I have notifications on, and still didn't get a notice for this.
Having antifreeze in your blood sounds like a cool superpower.
You had me at "naked" 😂😂😂
Hey Hank, good to see you on yet another pbs digital studios show! Blake at PBS EONS told me to check this out and say "EONS sent me" but im pretty sure you already knew that...
(TBH, and i have no idea why, for like 2 months since i started watching EONS I thought you were John Green........)
Great video, this was super interesting! The case of the icefish seems perfect for exploring the nuances of evolution, this video does a really good job at doing just that.
Thanks for the tiktok blurb. I now have another neat sciencey channel go binge
Amazing videos ! Love it ! I am always excited for new monthly videos .
I really love these videos so much! Very interesting indeed!
Joining my compatriots in the desire to let Hank know that I LOVE YOUR AWESOME SHIRT, MAN!!! the fish is cool too
Rewatching this... And still got fascinated
this was fascinating but also reminded me that im viscerally terrified of being underwater
Very interesting to see why red blood is so prominent in animals.
Here from Eons, loving this channel already. 💖 The fisherman in me, wants to go there and fish for these strange fish. However, that's far too cold for this hemoglobin rich human. 😋
Leave animals alone
I hope y’all still do this when I graduate college and have salary so I can get things like bizarre beast pins (nearly done)
Thanks for the neat video!
LOVE the pins!
I didn't know I needed this channel in my life.
We need some Hank-inspired merch, I WANT THAT SHIRT!
These fish are built for these conditions. Thank you Hank, and amazing shirt! Thank you for the great video!
I love this channel.
This is such a great channel from a narrative writing standpoint. I can already imagine a race of aliens with these properties and knowing why this fish is this way just immediately gives me ideas of how they might function work and what their drive would be. Really cool channel. Hard to believe how alien life on our own planet already is just from slight differences in mutations and environment.
Must have been "ugly shirt day" at the office !!
Someone tell that fish he is not swimming right.
They have clear blood, who are you to tell them they're "swimming wrong"?
This is the first vid I’ve seen of this channel and the moment I saw Hank I subbed
omg i learned about this in biology gonna send this to my teacher
informative and well presented.
Evolution is all about being “good enough” and working with whatever is at hand.
"They have really big hearts for fish their size" *casual footage of a vivisection* I wasn't entirely ready for that lmao
Hey this is awesome! Thank you for such a cool channel!
This is such a weird fish, I love this channel!!
Do we have an idea how climate change is going to affect this species?
These fish delicately fit into very specific ocean conditions. The warming water, drop in dissolved oxygen, and ocean acidification caused by Climate Change will likely be devastating for these fish.
Do you guys know much about the siphonophore? It seems like an interesting creature to talk about
Great channel. So many new things to learn. 👍👍👍👍👍🇨🇦
Jeez man, does this channel have an unlimited shirt budget or something? That is yet again a very cool shirt
You should do Sea Spiders in a video! Just learned about them in my bio lecture and those little guys are very funky
Hi, isnt the southern ocean also very depleted in iron? Maybe getting rid of hemoglobin is an advantage for the fish, as the production of hemoglobin uses a lot of that precious iron
frenetic as always, Hank. Please calm down.
I love this episode! I hope they make a video about why there are different colors of blood
I think there's one over on SciShow or PBS Eons about how blood has evolved several different times.
I click on an interesting-looking vid from a new channel and...
Hank is here, too. Dude--do you sleep?
Thanks for the talk. Does the genome of the ICE fish show some kind of globin or hémoglobin pseudogene ?
Thank you for teaching me about an animal I’d never heard of. Super weird fish!
I’m so happy to have clicked the video and BOOM Hank Green!
I need that shirt. Love ❤️ the new channel!!
Amazing shirt, Hank!
Would eliminating hemoglobin and reducing the number of erythrocytes in their blood make more room in their blood for the antifreeze proteins they use? Those antifreeze proteins help them survive in cold water, do to the oxygen rich nature of the water, could reducing hyboglobin to make room for more antifreeze be a good trade off?
Another fascinating creature! It gives me all sorts of imagination feels for alien life forms on ice worlds. A being of clear blood in oxygen saturated freezing water, what civilization could this become? I also loved the shirt, but I could not shake the feeling I was supposed to be finding Waldo somewhere in that pattern.
Anyone else love Hank so much? 😭
All these science videos are interesting in general but when he's the host i just get so haply lmao
Ah, that's why cold soda keeps its fizz longer.
How many channels will I continue to stumble upon just to be shaken by this familiar voice?!
Pretty late to this video but regarding that cold water holding oxygen better fact, is that why hot water from the tap in a cup looks cloudy for a minute from tiny air bubbles whereas cold water from the tap in a cup is almost immediately clear?
So, educator with a question: have you guys ever considered making any sort of companion to these videos, like a Kahoot, Quizzez, etc?I was considering making my own, to draw a bit more of it out of my students, but I figured I would ask.
another fantastic hank green channel yes please thanks eons
You just sent fishing vessels from Japan
Funny that so much of the *Ice*fish is white or clear, even the blood.
Still waiting on my pin for this one, but this is pretty damn cool.
I prefer when you do the videos, Hank! I know you’re busy though so no pressure.
I'm totally the other way. I find Suta absolutely intriguing.
Eons sent me and now I’m subscribed to another wonderful channel! 😋
Do ice fish swim around thinking, damn I'm cold?
Please do a pin on the mantis shrimp and just how crazy it is with punches that have the same force as a .22 bullet. Its crazy eyes and dress code, as well as its can do attitude
Wait wait wait.... I watch every SciShow and I somehow had no idea about this channel?!
this pbs youtube empire, j'adore
Funny how Hank did this one as well as the history of Blood as well on PBS Eons.
Interesting fish. Almost has Pike or Pickerel features, or maybe the other way around. Neat little artic predator :O
DUDEEE U SHOULD HAVE A PODCAST TALKING ABOUT THIS THINGS
Wow, that eye on the pin is not exaggerated at all
Freaky blood, cool (heh heh) fish! I just got my pin today! ❤ Good timing too, because last night I discovered what lovecraftian horrors scallops look to be, and I needed something to get my mind off their brain bending bizzareness.
I dissociated while watching this and came back to something totally different but equally interesting ☺️
Looks like a shocked and amazed albino pike.
This one has almost identical head to pike, now wonder it is such a cold blooded fish.
I’m trying to wait patiently for my mailman so I can get my pin.
A living anti-freeze bottle.
That ice fish pin looks like a Monster Hunter design, I really like it.
I love Hank so much! I think he gets his shirts from Amazon.
