- See clear blood run through the veins of the icefish, a demonstration of the process of natural selection. This video uses the Antarctic icefish as an excellent case study for genetic evolution and is perfect for all science classes.
See how these amazing fish avoid freezing in the icy ocean. Genetic changes enable icefish to thrive without hemoglobin and red blood cells. Natural selection has resulted in the “birth” of new genes and the “death” of old ones.

anyone gotta watch this for bio
yeah for biological anthropology turn up
Evolution class in the house
@@aurorasaura5907 same lol
Just hunger for culture
Let's take a shot everytime its says icefish
cool icefish stuff starts at 1:55
4:27
*stabs cod with a needle
Cod: :O
This made me laugh while getting ready to do schoolwork
"We all bleed red."
Icefish: hold my beer
Some bleed blue due to hemocyanin
@@SouravBagchigoogleplus Vertebrates?
When your parents say "we all bleed the same colour blood" Nah, not the Icefish
All science and biology students, sing the homework anthem!
The fish each time they open its mouth 👁👄👁
Some animals have blue blood due to hemocyanin.
4:15 "Except for the Icefish, all of the vertebrates on earth... have red blood coursing through their veins."
Not entirely true. Though most vertebrates have red blood, there are species from a group of skink lizards, like the Monkey-tailed Skink, that have green blood. Look it up.
Regardless, this video was interesting and very well done.
It's a weird broken down form of hemoglobin.
Horseshoe crabs also. They all have copper based blood instead of iron based.
And there is a type of simple life that has purple blood because they have a broken down version of the protein in normal blood
@@Dixitkushagra175 They are not vertebrates.
Horseshoe crabs have blue blood
I remember watching this like. 4 years ago for a science class
1. Describe the appearance of the "crocodile" fish / icefish.
2. What is the relationship between blood fluidity and temperature? What is the reason for it?
3. How does the "antifreeze" work in the icefish?
4. What is the proposed explanation for the appearance of the antifreeze gene in the fish around Antarctica?
5. How do the changes in the globin gene tie into a) where the icefish live? b) other parts of their phenotype? c) why the icefish still have the gene?
do your homework
I know this is well late, but the video literally explains all of this. I hope you got your assignment in after watching this. haha
This is cool
A remarkable example of life, yet again, finding a way. Great science here. Well done.
"In the past, their scaleless skin had been widely thought to help absorb oxygen. However, current analysis has shown that the amount of oxygen absorbed by the skin is much less than that absorbed through the gills.[19] The little extra oxygen absorbed by the skin may play a part in supplementing the oxygen supply to the heart"
So this video had errors in it. Did you catch them? Nope. Slap something with "science", you buy it hook line and sinker! "gReAt sCiEnCe hErE."
Also, several species in this family do indeed have some hemoglobin, but it is low % and non-functional. So many errors in this video.
wow. Can I use this in my Biology paper?
Brilliant
Bro Icejjfish looks crazy in this
Cool fish.
I see what you did there.
The Icefish is scaleless much like the Sterging and Catfish.
8:20 drake passage
My basic biotechnology subject brought me here. And find it interesting
Amazing!!
Thanks!!
I have to, with all this genetic manipulation going on.... can it be possible for this gene to be use in humans inorder to be able to go into more extreme environments.... ?
Im in the final of Bio. Wish me luck.
Good luck!
Life..uhh.. finds a way
Is the Ice Fish edible?
who else is watching for bio?
Any Ice Fish Cavair?
the creator of comedy sent me to this wonderful video
maybe this fish have some specail material will applied for man to execute long traveling between the cosmos,a guess
Does anyone know how/why the icefish got rid of their scales and gained the ability to breathe through their skin before they lost their hemoglobin?
I figured it out so, I'll answer this for anyone else confused: They just happened to be able to get enough oxygen through their skin before they long their hemoglobin. It helps that oxygen is more water soluble in colder temperatures.
Its the weed maaaaan
How about the Horse Crab?
Anyone else watching this for Bio?

mutants
bio gang
The Potential of this Amazing, isn't it? Increasing the Chances of Life on Cold Planets. Think if we can extract this DNA (X-Men) Mutation Trait and add it to combination Human/Mechanical Beings . This opens up the idea that we can change and adapt for colonization of planets that are there but too cold for the Red Blooded .
found this on google after watching a minute earth episode about antarctica
That scientist is a dead ringer for Kevin Spacey.
Don't tell CHINA of the LOCATION!
Mr freeze must have a lab there finding cure for nora 😀
What would happen if see threw blood was injected in to humans what would happen mutation or get a sick person healther
nothing would happen
what of say. none of mutation in human nore better
dna 10:20
Is it possible for ' aliens ' to take 1 fish specie from their homeplanet and dump it here in order for that specie to survive ? Im just thinking....It has no colour in blood.. A possible alien? (ice fish) more like Alien fish.
No, it is in no way a alien, it just doesn’t have haemoglobin because it’s too cold, but the water is extremely oxygenated, so it’s saturated in oxygen
@@Lordmun445 An Epigenetic change perhaps?
Loss of function is not "evolution".It is Adaptation
No, it is evolution and adaptation.
Or a mutation
idc
Mmmm ya this is so hot.
DRINK IT.
Wtf😂
I could only watch until about 4 1/2 minutes when they said that all other life has red blood, that’s like so inaccurate LOL
Vertebrates...
The Antarctic blackfin icefish is the only known vertebrate animal that lacks red blood cells containing hemoglobin. But the use of hemoglobin to transport oxygen through the body is actually a rarity among invertebrates, which rely on a variety of other pigments in their versions of blood.
Amazing, Allahu Akbar the Creator 😍
This is proof of evolution
Cancer fish
LAUGHABLE evolution FICTION
