The Bizarre Beast with Clear Blood

[@KrazyKaiser]

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.

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.

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.

[@syos1979]

@@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.

[@quitlife9279]

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.

[@devinnall2284]

It probably evens out since they need 4x more blood

[@quitlife9279]

@@devinnall2284 blood without haemoglobin is probably not much more than water, and it's a fish...

[@asdu4412]

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.

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

[@VyvienneEaux]

In my intro college biology class, we learned that the icefish had the advantage of lower blood viscosity because it lacked hemoglobin.

[@emilysmith2965]

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?

[@anonomooose]

@@emilysmith2965A lower blood viscosity makes it easier for the heart to pump. This increases blood flow(at least in humans)

[@AnnoyingNewsletters]

Maybe they don't have -platelets- thrombocytes, either? In their niche, it's be alive or be lunch, with not much in between.

[@DJFracus]

They would require less iron as well.

[@ruslbicycle6006]

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.

[@xEricC1001x]

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.

[@janjanzen1218]

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
