Extremophiles: Organisms That Live in Extremely Cold, Hot, Acidic, or Salty Environments | GEO GIRL

[@sharksuperiority9736]

Its interesting that the maximum temperature organisms can tolerate is significantly more extreme than the minimum, compared to >100 Celsius,

Goldfish are facultative anaerobes. They, along with some other carp, can switch to anaerobic metabolisms. In the winter when the surface of their pond freezes to a solid sheet of ice, the ice can block oxygen from entering the water. Other fish will die when the water runs out of dissolved oxygen. But the goldfish switch to anaerobic metabolism, which also creates alcohol as a waste product in their bodies, to the level they would be over the blood alcohol limit to be able to legally drive. Be glad that goldfish don't have cars.

Loved this video !!! Extremophiles are such an amazing group of organisms. I'm glad you took the time to shed some light on them because in the end, we all likely evolved from an ancient ancestor of today's extremophiles, either near a anoxic deep ocean hydrothermal vent or a halophillic shallow ocean pool.

[@GEOGIRL]

Thanks, I am so glad you liked it! I agree, I think it is such a neglected yet amazing topic! ;D

[@vomeronasal]

I was "the anaerobe guy" in a regional reference microbiology lab. Oh, the smells!

[@GEOGIRL]

Oh yes the smells are something else! 😂

Impressive summary of extremophiles, GG :) I keep reading on these and get fascinated by enzymes that these extremophiles might harbor. I recently read about EAMs, or electroactive microbes. They exhibit extracellular electron transport with minerals/metal surfaces to drive their energy requirements. I would love if you would make a video on them since they also have been found in extreme conditions :)

[@GEOGIRL]

What a great topic idea! And actually pretty relevent for my research! I will certainly make a future video on this :D

This was radical.

Interesting to see archaea mentioned for once They always talk about bacteria when it comes to microbial life in either the present or the past and archaea pretty much get neglected For example, they always talk about how cyanobacteria spewed out all this oxygen that caused the GOE, but how are we so sure it were cyanobacteria or cyanobacteria alone? Have halobacteria never played a role in this? I mean they emit oxygen as well, right?

[@TheRexisFern]

Ah, the joys of such studies! Welcome to the Fart Lab!

[@GEOGIRL]

Haha I know right 🤣🤣

[@Smilo-the-Sabertooth]

Wow, how remarkable that some organisms can survive in such environments. Just goes to show how resilient life can be. Another interesting topic and educational video Rachel. You never let me down with your absolutely incredible videos. I hope you’re having a Happy Easter my friend. 😊❤😉👍

[@GEOGIRL]

Well for them, we are the extremophiles, for them those environments are 'comfortable'! haha Happy Happy Easter my friend!!

@@GEOGIRL Thank you my friend, you’re amazing. ❤ And I apologize for commenting so late. Just know that I still watched and enjoyed your video as always.

[@GEOGIRL]

@@Smilo-the-Sabertooth Never a need to apologize for being late, just the fact that you watch and comment at all makes my day! ;)

@@GEOGIRL And that’s one of the reasons why you’re my favorite teacher, being late is no big deal to you. You really are the best Rachel. ❤😉 You and your videos always make my day.

This video needs some love and since I ❤️ GEO GIRL I’ll watch it.

[@GEOGIRL]

Thanks Joe :)

nice cat I've spot her at the beginning of video when she's bumping wall with head (yeah I know there is some bowl but it looks like). personally I so understand her :) it's not boring but I fell a sleep while listening of some your old videos

[@GEOGIRL]

Haha, trust me I know some of these topics can be boring sometimes! I only would listen if I really need to learn it, but I am also grateful there are people out there that like to watch them even as non-students ! ;D

[@YuriyKuzin]

@@GEOGIRL but some topics really interesting even for someone who used to be student long time ago from absolutely another area :)

That cat is chopped liver compared to me.

You said it gets 110 down here where you live where is that? Just curious I’m up in Illinois the winters here suck

[@GEOGIRL]

At this time I was in Texas, but I am not in South Carolina (both of which get to 110 haha) But I am not good with cold so I am sure I'd have an even harder time in Illinois ;)

[@ericlewis9472]

@@GEOGIRL yeah Illinois is cold I want to eventually move away but I am originally from Augusta Georgia lived there until I was 24 that’s why when you said down here I was curious where?Lol

Hi GeoGirl, where is my clay minrallssss😃😃🙃

[@GEOGIRL]

It's coming, but I had to put video requests on hold for a while because I am substituting for one of my professor's historical geology class for the next few weeks and have been making those into videos since I don't have time to make multiple lectures. The sed/strat clay minerals video I am planning isn't going to be able to happen until after the end of the semester, at least a couple months, I am sorry :/ I also just don't have a lot of references on clay minerals, so I am having to do more research for that video ;)
