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.
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?
"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."
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.
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.... ?
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 .
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
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.
anyone gotta watch this for bio
yeah for biological anthropology turn up
Evolution class in the house
@@AurorasAura4417 same lol
Just hunger for culture
Let's take a shot everytime its says icefish
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

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
cool icefish stuff starts at 1:55

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
Some animals have blue blood due to hemocyanin.
he said vertebrates, to my knowledge animals w/ hemocyanin are invertebrates (ex. horseshoe crabs)
All science and biology students, sing the homework anthem!
A remarkable example of life, yet again, finding a way. Great science here. Well done.

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?
The fish each time they open its mouth 👁👄👁
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
8:20 drake passage
The Icefish is scaleless much like the Sterging and Catfish.
I remember watching this like. 4 years ago for a science class
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.... ?
Cool fish.
I see what you did there.
Im in the final of Bio. Wish me luck.
Good luck!
This is cool
Any Ice Fish Cavair?
My basic biotechnology subject brought me here. And find it interesting
Is the Ice Fish edible?
Amazing!!
Thanks!!
Bro Icejjfish looks crazy in this
How about the Horse Crab?
8:55
mutants
Brilliant
the creator of comedy sent me to this wonderful video
who else is watching for bio?
2:20 bro really went 😦
maybe this fish have some specail material will applied for man to execute long traveling between the cosmos,a guess
Life..uhh.. finds a way

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
Anyone else watching this for Bio?
dna 10:20
Don't tell CHINA of the LOCATION!
That scientist is a dead ringer for Kevin Spacey.
found this on google after watching a minute earth episode about antarctica
bio gang
Mr freeze must have a lab there finding cure for nora 😀

@@Lordmun445 An Epigenetic change perhaps?
Loss of function is not "evolution".It is Adaptation
No, it is evolution and adaptation.
Or a mutation
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...

Amazing, Allahu Akbar the Creator 😍
This is proof of evolution
idc
Mmmm ya this is so hot.
DRINK IT.
Wtf😂
Cancer fish
LAUGHABLE evolution FICTION
