It seems obvious that animals need oxygen to live, but deep in the Mediterranean Sea there is a very small animal that might be doing just fine without any oxygen at all.

I was hoping it was a picture of Congress with a title like this!

no such thing as convincx or not

This video is pretty stupid, making look like all animal life need oxygen by default.
In the early earth there was not oxygen, it was a magma ball and when at last oceans form that water was mostly sulfuric water without dissolved oxygen on it and there bacteria live happily for many hundred of millions of years without any fuss then a kind of bacteria start defecating OXYGEN(oxygen was literally poisonous for early bacteria) then when the oxygen levels on water increase and bacteria start dying some bacteria develop resistance and start feed on it THEN is when life on earth start using oxygen to live than result in a faster way to get energy.


That is why nowadays animals need oxygen because it is more efficient and animals than feed in other chemicals are no rival for oxygen eaters.

Haha, my brain broke a little when you *didn't* say "the powerhouse of the cell" after "mitochondria." XD

I thought that bottom of Black see has some creatures that don't need Oxygen as well...

ill never understand why ppl are so dead set on it having to be oxygen breathing aliens. if they are aliens they probably dont breath the same air.

0:45 you literally have shown how sulfate and nitrate has also oxygen in it...

Life uh... finds a way

Though it's great info, the one we need more are jellyfish, they're the harbingers of the sea should there be a dead zone in the ocean.

The bacteria that cause gangrene is a STRICT anaerobe and gas gangrene spreads SCARY fast in the human body, so fast that you can actually see it spreading if you watch it. The it was an absolute killer of troops in WWl and previous wars but they discovered in WWl that the best (and only) way to kill it was amputation and oxygen immersion and saturation, that's where oxygen tents were created and in some situations are still used in hyperbaric oxygen treatment today.

I just shared this video with a friend of mine who does basic research on mitochondria using CRISPR-CAS9 to knock out genes and see how those organelles react. She is kind of an expert on the functions mitochondria serve other than producing ATP, like how they help cells divide.

Me: Watch me breathe with no oxygen needed
Also me: i dont no helmet i got a plastic bag

Not sure if ''These Animals'' seen in the title is the right words.

The First Extinction of 2019 Has Already These Animals Don’t Need 5 months ago   05:51

On New Year's day, we said goodbye to George the Snail, marking the first extinction of 2019, and the way things are looking, it won't be the last.
