They really look like dragons, hope we could record a "dragonborn" tardigrade with them one day.
"Dragonborn" tardigrades are a thing?
Sorkabeth believe, believe, the Dragonborn comes.
Dovahkiin...
If that day comes, observing them in the lab would be nearly impossible. They'll FUS RO DAH themselves out of any slides they're put in...
ayyy
When Hank said how the cilia on the Gastrotrich's head were sensitive to the motion of the slide, I suddenly remembered that the camera was not panning over the environment, but that the environment was moving according to the slide. It really reminds you how perspective changes everything.
I didn't even think about that. I actually thought they managed to make the scope itself move
I don't understand
Can u please explain
@@shashwatchamoli7221 When you use a microscope you have to put the microorganisms or cells on a thing called a 'slide' and that slide gets put on the stage of the microscope. The lens is what you look through but you don't move the lens to look all over the slide, you move the stage or the slide.
Check out this crazy lady ua-cam.com/video/Osjp3W7cgT4/v-deo.html
@@anteconfig5391 Actually i know about the basic usage(lens,slide)but what is confusing me is that we actually don't love the lens and won't moving the slide create some disturbances which will affect the movement of these sensitive microbes.
Thank you for replying btw....
@@shashwatchamoli7221 sorry, I mean to reply yesterday but I guess I forgot.
Yea, you're right moving the slide would do that but at the same time we're talking microns of motion so the liquid they're in shouldn't move very much. I guess that's why those hairy grandmas can sense this motion.
I think that if they managed to move the lens instead that the microorganism wouldn't be able to feel the motion.
I think I prefer to translate Gastrotrichs not as "hairy stomachs," but as "fuzzy tummies."
WulfgarOpenthroat 🙌🏻💯💯💯
:3
Yes
WulfgarOpenthroat stomachs are the baggy sacks inside you that breakdown the food chunks you eat, a hairy one would tickle you from the inside
@@captainretro373 Well we have lots of nerves in our digestive system and we don't feel our half digested food sliding along, so hopefully that particular stimuli isn't consciously felt.
Moral guardians in the 80's: "Babies having babies!"
Gastrotrichs: "Why are they waiting so long? Do they think they'll live forever?!"
If ever you guys do a behind the scenes episode or the like, I’d love to hear more about the music. It’s pretty unique amongst these kind of “nature-y” videos what with the bass heavy tones
Speaking of the music, if you're into anime, the music has similar vibe or effect of those used in Mushishi. This channel actually reminds me of that anime. In Mushishi they explore the world of usually unseen "things" that affects the human world. And those things looks like these microscopic life. Its kinda similar how Greek mythologies try to explain everyday things using anthropomorphic gods but in Mushishi the things that causes maladies and stuff are these microbe-like things that are usually invisible to normal human.
To anyone interested, it's a relaxing anime that covers mature and a bit of dark content.
It's made by a really cool artist named Andrew Huang if you want to check out his channel: ua-cam.com/users/andrewhuang
But I agree it would be cool to hear him talk about making music for JttM.
+1
Andrew huang listen to us! And make a video about the creative process that goes on to make such compelling music
Andrew Huang's soundtrack was available as a Project For Awesome perk a week or so ago but I think the P4A site has closed now.
@@avariceseven9443 Mushishi is an AMAZING series and I recommend it even if you aren't a fan of anime. It's mellow and fascinating. And the soundtrack really is beautiful.
*Gastrotrich Grannies make the best cookies. My favorite are the activated sludge flavored ones.*
Those are so damn good, i like when they're covered in Ribosome chips
Help me how do i get back to ryans toy review
Why you bold letters rotifer?
I like rotifer meat (yum)
Are you going to add any content on you channel or what?
I just wanna take a moment to appreciate Andrew huang's music
Gels soooo good with the video❤️
"This one's Neil" Perfection.
Made me choke on my hit 😂
is it bad if my mind autocompletes "Neil" to "Neil Kinnock"?
Is that like Neil from the "Young Ones" ? Dig that music too...
@@sitarnut That would be very heavy, man! Boomshanka!
I was thinking "Is Neil very technically proficient on drums?"
I look at cute kittens on other channels, a cute husky here, a cute cosplayer there. And then there's this channel. The microbes, well, ~~ But the narration is cute!
I dig this channel
Seriously? I see you everywhere!
Yea I'm addicted to this channel. I absolutely hate the way he talks when he narrates but I always find what he's talking about extremely interesting.
"it's 1:24 am i should probably go to bed"
*sees new microcosmos video*
*sigh* "fine"
So true lol
I usually watch these if I can't sleep.
I put a playlist on my phone and listen to it
*Sees title*
“Brother pitted against brother. Babies havin’ babies”
- Strong Bad, 2004
Ah yes i love to go to my subscriptions and see a big thumbnail that says "hairy grandmas"
*Calling Tardigrades "cute?" Am I a joke to you mortals?!*
yes
Rotifer you sure are
@@blumac9801 a lie
Ye be wise not ta draw from that well what be tha endless malign intent of tha rotifer... Laddie.
What's your beef with the poor Moss Piglet, Mr. Rotifer?
It's amazing how with a small change of focus the already-magnified water suddenly comes alive with swarms of bacteria
This reminds me a lot of “true facts” but on the microscale and more informative
Qwertyuoip 123, “that’s how gastrotrichs dyoo”
@@evilsharkey8954 They dig a little hidey hole where they lay their eggs, which later hatches to become little gastrotrich bebbes.
I love your videos. The soft background music, the mellifluous voice of the narrator, and the beautiful visuals. It's like a dream world. Thank you very much.
Ohhhh, a microorganism i’ve never heard of before! Fascinating! And cute... and kinda hairy. Perfect watching before bedtime.
Amazing pictures. James really is a master of microscopes.
I want this series to never end... : (
3:40 This one looks like it has a number on it, in almost perfectly proportioned sans-serif font..
haha it does. 88, 99, or 66? I can't tell.
28 or 29 :?
29
CL Melonshark nice
Looks like 88 to me.
One of my cats sat transfixed watching most of this video. Friggin' adorable.
Ah, okay, when Hank said "hairy stomach" I was imagining the organ, stomach, being hairy, either internally or externally, and couldn't figure out what the function of that would be. I was on the edge of my seat waiting to find out! Turns out it's a hairy belly, not a hairy stomach. I am outraged.* False advertising, Hank. False. Advertising.
*I am not outraged.
Same, I was so confused at first
Hairy creatures that are ready to give birth once born. They're tiny tribbles.
There are more extreme cases. There are creatures that are not only born pregnant, if conditions are wrong for giving birth for an extra day, the baby inside can become pregnant.
hamjudo What are those creatures called?
the best protozoology education content ever
I love gastrotrichs! I did a mini lecture on them in my first year at uni! I saw one by accident down the microscope during a practical session and I loved the look of them, so alien, so I asked to present them in a section of a lecture
Having a ruler next to the magnification level to indicate the size of a millimeter for example would be incredibly useful for understanding the size of these animals. 400x means nothing but 0.06-2mm is understandable.
agreed. I suspect there is some sort of traditional reason around indicating the level of magnification, but sense of scale would also be helpful.
8:32 what are those spiral snake like things??
Spirochetes, a bacterial phylum that's pretty recognizable by this shape and motility pattern. Some examples: Treponema pallidum (causative agent of syphilis), or Borellia burgdorferi (causative agent of Lyme disease).
Are you sure those aren't sperm cells?
@@cockthesheep3051 Sperm cells are divided into ovoid body and a flagella tail. Spirochetes have undivided corkscrew shaped bodies like the ones in the video, without flagellum.
@@jonclarke8397 was about to ask about that. thanks for clarifying. and also, i had studied this some days ago in class and found it interesting to see on the video these types of creatures.
@@jonclarke8397 are these spirochetes all either S twist or Z twist?
Another wonderful installment. One of my cats continues to go out of his way to watch these with me.
"We name individuals all the time - this one's Neil -"
Idk why, but I found that incredibly adorable. Hi, Neil!
Sometimes I wish I was a naturalist in the 1800’s, so I could name something really cool and wild, like “vampire squid from Hell”.
help me ive been trying to get back to ryans toy review and i just keep getting more videos of big words and oozy caterpillars and it makes me want to do bad things
Is there any practical limitation that prevents mounting a microscope upside-down to enable views from below? I can't think of one myself.
i guess they would have to have a special microscope ordered, as they cant hold it upside down (cause of the slight movements affecting the creatures) and maybe they dont want to damage the microscope by nailing it to a table or something.
This channel is soooo peaceful. Thanks to all who made these beautiful videos.
“Oh boy, I’m having a normal day. I hope nothing strange happe-“
*“HAIRY GRANDMA”*
Thank you as always, A Wonder to behold. Thank you Hank, Jam, Andrew and the whole crew. This really is the only thing on you tube that is always simply 100% interesting, amusing and delightful. I could happily watch these films all day long.
Is there any way to buy the music Andrew made for these videos? really love it.
What are those spinning spirals ? If anyone knows please let me know :)
Their waxing bill must be huge.
It's like a cross between a rotifer, and a nematode...
This channel keeps getting better and better. The footage in the past couple videos has been jaw dropping.
he looks like the "Thing that drifted ashore" from Junji Ito.
What a fantastic channel, I am binge watching all of your episodes.
So awesome. I wish I could find cool things like this more often. I love the reference to Shakespeare.
Being a “Gastrochic” I am deeply offended. But I am almost out of time and now my life is about over. Thank You
Right now a group of gargantuan trans-dimensional star beings have taken our Universe, squashed it into 4 dimensions between two unfathomably large pieces of glass and are peering down at us through an immense macro-microscope and they're saying: "Look at the little Human Being, or Hairy Head, as is their common name. It only lives for a brief 80-90 years, but after just 28 years, it is already about to give birth."
The most amazing and fascinating thing to me is knowing that each moment of every day on this planet there is this tiny unseen world that is thriving and living all without majority of us ever seeing them. Thank you for this channel on youtube you have created, I love anything related to biology so micro biology is no different to me ^_^ . Wish things like this would have been done in my school curriculum when I was growing up but no it didn't happen, keep on going guys continue this wonderous work :).
Hairy stomachs never looked so good :D Everything on this channel is so fascinating.
Good video✌
ive been thinking of buying a PC microscope cheapest 2mp $25 to $500
be cool sitting here watching everything so small & recording it all .
And I would like to say thank you to Niel. You missed them in your acknowledgements!
8:17 Now that you've said it, I'll bet one of your viewers will now spend a week tracking and filming a singular gastrotrich through it's whole lifespan, hoping beyond hope that there are no predators in the sample or at least none within range of eating the subject and getting that precious information
It would be funny if Earth had been visited by similarly intelligent aliens, but they were microscopic, and we've simply never interacted.
This channel is only thing I watch on ytb now. I love the way you take us into microcosmos 👏👌
*Journey to the Microcosmos is just awesome!*
Veganism defeats carnist nonsense every single time 👍
@@ichomann2 LOL.......you found me!
Imagine aliens that live millions of years observing humans reproduce within "days" after birth and day a few days later.
The only "Hairy Grandmas" videos acceptable to watch.
This Channel makes me love science even more. An impressive feat for someone so jaded as I am with modern stimuli
Nice to meet you, Neal.
Glory be to Allah 🙏🤲🏻❤️❤️❤️❤️❤️❤️❤️ Creator of everything
Talks about gastrotrich but shows footage of microplankton ,🤔
I kind of want a dog sized one of these as a pet.
As long as their lifespan was scaled up as well! I already can't handle how short-lived dogs are
@@Skittenmeow You would get a new one every day!
Um...No.
ua-cam.com/video/UHPbTuSOKaA/v-deo.html
@@Skibbityboo0580 I've got a puppy who has just finished teething, don't want to think about experiencing the gastrotrich equivalent each day 😉
@@kendrickkelly2336 omg wrote my comment on gastrotrichs teething before I saw your comment and clicked the link. Very appropriate!
3:41 gastrotrich number 29
what are you talking about?
"What they use the sperm for though, is a mystery."
Really? Well I can make some assumptions.
yeah, it just hasn't been observed.
Another species in which it is a mystery if the males make any real difference in the scope of its entire species
wow I read about small phylums like gastrotrich and chaetognatha since high schools but this is the first time ever I see their live video, satisfied my curiosity so much
酥饼, I wonder if James will ever find chaetognaths. They’re pretty badass looking for micro critters but probably a bit larger than he’s interested in.
Wouldn't it be awesome if they went to Greenland and found Limnognathia maerski !
It's the only species in it's phylum !
@@evilsharkey8954 probably too hard to cultivate them anyway, it looks like James only does freshwater meiofauna and microfauna
This is genuinely a insanely great channel. I’ve not even got a clue why I’m watching this but it’s absolutley mental. Top marks
I watch this and daily dose of internet on my lunch breaks. They both calm me down and astound me.
This channel has easily become one of my favourites!
0:11 & 8:32 What does "Slowed down 500%" mean? Do you mean you're playing it backwards at quadruple speed? Or do you really mean "Slowed down 80%"?
It means 5x the frames. You don't slow down videos by making frames longer, you add more frames. While this video has a certain amount of frames per second, the camera footage had more of them, so by adding or subtracting frames you can make it slower or faster compared to the refresh rate of this video, thus allowing five seconds of video represent one second of real time.
@@Niinkai I get that. But if you do that, you are slowing it down by 80%, not 500%.
@@RadicalCaveman it is notated either using frame multiplier (500%) or multiplier of original speed (x0.2)
@@Niinkai This could lead to ambiguities. "Slowed down 50%" could be either frame multiplier x 1.5 or half the original speed.
At 1:22 does anyone know what those little creatures are on the hydra? Love these videos & am very grateful for the opportunity to learn about the nearly invisible to the naked eye micro universe right in front of me that I’d otherwise only have access to through a costly lab (most likely at a university that requires you to be a student taking a specific class).
kerona
You’ve probably eaten these before.
Ive found my new spotify password.
It's hard to believe these are closely related to ostriches
I like that shot that starts at about 8:08 where the microscope is out of focus and we can just make out the spines on its back. In the other shots you can see the side spines but in that one you get a much better view of how they are actually arranged.
can you do one on nematodes and flatworms
i named my eldegoss in pokemon sword “HairyGrandma”
i'm in love! can any of you pay for my school? i'm so sick of being a wage slave!
jk though, i'll get there eventually.
Huh! I'm surprised no one's invented a microscope that films from the bottom, up.
Keet Randling, most microscopic organisms don’t orient themselves by gravity. You can see most of them orient themselves by their surroundings.
Hello, I have a request. Can you make a video featuring thiomargarita namibiensis?
Vengeful Camel, he’d probably have to order them, if they’re available. They’re not something you just find in pond water and hay infusions.
Evil Sharkey
Yeah, they’re pretty restricted when it comes to distribution. And also, despite being bacteria, you really don’t need a microscope to see them
I had a few hairy grandmas onced !!!
This Gastrotrich is the "Kiwi bird" of the microcosmos.
The last time i was this early the microcosmos was all there was!
Do other species perceive time at the same speed as us?
Dude. I kinda wanna scream "FALCORE!" while watching these little wingless pooping dragons.
Interesting how do you identify all of those creatures? For example if I will buy microscope and catch one of those guys, how can identify what is it?
Coffee in my left hand. Pizza with some microorganisms in the right hand. Biology book in front of me. Now lets learn about Gastrotrichs.
At 3:40-ish in the video basically what the host is saying is, these hairyback and their meiofauna kin ... they poop. So now you know kids. Everything. Poops.
3:13 MEIO fauna, Meio translates to "middle" in portuguese
and it's pronnounced
Meh-yu
5:40 gastrotrich: * touches tiny organism *
tiny organism : RUN, RUn, THE WORLD IS ABOUT TO END * teleports out of the world *
I always get sleepy watching these videos, and this is not a negative critic, the background music, his soft voice, everything calms me down
So you have a phylum for every animal with a backbone
You have a phylum for 3.7 million species
And you have a phylum for hairy microscopic baby grandma things
Neil, the hairy grandma
23 seconds ago. That's weird
I vote we change the names from hairy stomach to fluffy tummy
kitplaysstuff, I’d prefer “swimming cactus”.
As a general microcosmos comment, I found this article published in 2014:[Genomic Encyclopedia of Bacteria and Archaea] www.ncbi.nlm.nih.gov/pmc/articles/PMC4122341/ . Some of the numbers are interesting - 11,000 validly named type strains which have been cultivated for research. And this seems to represent less than 15% of the of the known prokaryotic diversity. So, when we look at a drop of water through James's microscope, is it a fairly safe bet that many of the little critters that we see along with those under discussion are yet to be named by anybody? Or have I misinterpreted the numbers? Do we know how far GEBA has progressed?
[Camera backs out, a yellow name badge labeled "Hank" is pinned to a friendly man already engaging nearby tables in engrossing discussion.]
"And through that lens, we see a meal that is both entirely new, and unknowably ancient. And as we look, still in the earliest days of charting this menu, of cataloging strange condiments choices that defy or blur the classifications of breakfast or lunch…."
[A manager speaking with her new assistant, who is unfamiliar with this Sunday morning phenomenon, unobtrusively observe from a nearby corner:]
"… Then we tried putting him on drive-through, but cars would park circled around the ordering speaker and drive-thru window until his family finally finished eating."
"…We see, among those myriad, mysterious egg dishes--those bejeweled hash browns and sizzling proteins that make up our initial glimpses of the Grand Slam: --an ensemble of pancakes or waffles: large compared to many of the other entrees we see, their breaded bodies adorned in chunks of butter and immersed in maple syrup…"
[Wondering where he got a classic 60's diner-style white paper hat, and thinking it an odd choice to go with the neatly tied apron worn under his formal coat, the assistant asks:]
"But if he backs up crowd on Sundays, why don't we just schedule him different shifts?"
It's that bright color that will end up identifying it, not just by sight, but by name: orange juice, for the herald of bittersweet intense flavors encountered and whose grainy pulp, as ingested, is said to carry the nutrients of fifty grapes…
[The manager stifles a warm laugh:]
"I forget your new, I thought he worked here too when I first got hired as well… Oh.."
"Oh no, he's getting his guitar out. Someone must have asked about the Moons Over My Hammy. This is going to take a while, we need to get everyone back to work, now!"
[Camera pans slowly out and out. As a guitar, then accompanied by slow bluesy singing, begin to play it becomes silently apparent that the managers efforts are completely in vein.
Before the scene fades to black... the managers are seen joining the circle formed by their cooks and waitstaff, so they too, can enjoy what's left of the 8 to 12 minute show, provided to them every week, out of sheer kindness, of some awesome people's hearts.]
Great video except...please dont put titles, words, and numbers right in front of your filmed subject matter...you think 40000 was big enough?...suggest to put the words upper left corner under the magnification information..Thank you for these videos.
Gastrotrichs are the OG middlemen (psst.. Wanna buy a watch?). CAN YOU PAY THESE MONIES?!
One day in microorganism school:
Teacher - Okay class, share your name with the class so we can all hear it.
Tardigrade - My name translates to Slow Stepper.
Hydra - I got named after the Greek monster Hydra.
Teacher - And how about you Gastrotrich?
Gastrotrich - Um... Hi. My name is Hairy Stomach. Nice to meet you all.
Right when I thought "what are those squiggly lines? Nematodes?", you said "over 40,000 species of nematodes" lol.
Those with the black backgrounds are simply beautifull.
Anyways, their behaviour reminds me of mice.
