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.

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.
@@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.
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
@@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.
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?
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.
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.
@@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.
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.
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
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.
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
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.
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"
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 !
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...
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.
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. 😋
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.
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.
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.
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
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
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.
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?
Good question. If I had to guess, that one fish was probably in some kind of distress. They get stiff when in distress. They are very anxious in general.....In some of the other footage you can see their mouthes stuck wide open. That's the same kind of stress reaction.
Quite a few fish curl like that to make themselves "wider" and harder to swallow for a predator (or to put particularly pointy fins as pointy as possible in all directions), so yeah, it's a defensive posture!
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?
When you have a low metabolism already and have to sometimes survive extreme scarcity, not needing to produce haemoglobin would probably be a net benefit. Especially in the Antarctic where bio-available iron is very limited.
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.
Hemoglobin or the genes needed to create it also affects the shape of blood cells. I wouldn't be surprised to find out that the shape of heme-less blood cells are ideal for their cold environment.
3:22 I think the mutation is deliberate instead of random because of the environment. Also preys tend to stay in areas where there are less to no predators.

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.

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.
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

Why does their tail curl like that when they swim?
