I love to imagine the rotifers planning to leave the colony like with little conversations and tearful goodbyes.
Goodbye my friends! Im going to test my luck on the next puddle!
Aight im boutta head out
Now I do too. Thank you for sharing 💝
Imagine if they actaully had some type of emotion, even if very simplistic. That would be very unique
what's sadder is that they'd probably die immediately afterwards
Microscopic vacuum cleaner: surviving dehydration.
Biologists: “sleeping beauty!”
Those who came up with this channel's approach and production are to be deeply commended. The fantastic microscopy. The gentle, comfortable audio. The flowing casual-yet-educational scripts. Some folks Didn'tFTBA. Great work. Thank you.
listen to "the Anthropocene reviewed" podcast for John green's gentle audio, which was where hank got the idea to do something with gentle audio, and we all got lucky that he found this to try it on.
Jam’s Germs, Andrew Huang and Hank Green, respectively, are owed thanks. 3 paragons of RUclips
FTBA?
@@EggBastion DFTBA = Don't Forget To Be Awesome, and is an ackronym used by the vlogbrothers (who are John and Hank Green) community. I'm referencing that.
_Awww, crubdumps._ To be fair I shoulda given Google Hank's name as well as just the letters - although by that point my brain might have started working by itself. Might've...
Hank sounds like he is trying to either seduce the Rotifers or doesn't want to wake up the lil ones.
I'm picturing him bent over a petri dish, murmuring little lullabies to tiny little creatures.
I didn’t realize it was Hank Green, I hate that guy, even though I liked the narration on this one. Hmm...
In places, it gives me a zfrank vibe.
@@danfg7215 I don't /hate/ the guy, but he narrates way too hard. I wish he'd just speak a little more naturally
@@yaj126 yeah, I don't hate him personally or whatever, just his style in most videos, sometimes I just close the tab when it's a scishow video and he pops up.
A little correction: the rotifers' "jaws" are called the mastax, trophi are each one of the many pieces that, together, form those "jaws".
Continue on your journey of knowledge, great man, I'm sure that the channel will appreciate your kind correction.
You forgot to say... Actually... and push up your glasses. 😁
You also need to consider the audience. Like me, for instance, a total dumb ass on small wriggling goopy things. Human jaws are the maxilla and mandible - but we don't refer to them separately. I think just saying "jaws" in this context is okay as well.
MattExzy he was making a distinction because the video stated that the jaws of rotifers are called trophi, which is incorrect, as trophi are the parts of the mastax, which would be the better equivalent to jaws.
@@MattExzy well you say you're a total dumbass, but then you say you think it's okay
has it occured to you that your opinion might be wrong
I was hoping you’d have footage of the predatory synchaeta rotifers. They’re much more badass looking, with some of their cilia fused into curved spike-like structures, and their little trophi look like piranha jaws!
So they're microscopic langoliers?
Looked them up, really cool critters!
They seem to look like the one at the beginning of the video.
remliqa, the one in the beginning looks like a loricate rotifer, which also wasn’t really discussed. They have a hard shell, often with spikes, that makes them less tasty to other critters. Synchaeta have some of their corona on the side like tiny water wings.
how did I read structures* as strawberry
*corrected spelling
"imagine this Rotifer..." sorry Hank, I can only imagine it in its hungry hungry hippo mode
Rotifers are the one microorganism I’ve been able to keep in a petri dish for years... you forgot to mention the nifty horizontal gene replication some species are capable of.
They are making clones?
The ones I got a hold of were bdelloids. They are know to reproduce asexually through parthenogenesis but they also do horizontal gene replication which prevents full on clones. They take ‘you are what you eat’ to a whole new level, stealing bits of DNA from those cells.
@@elizaalmabuena Okay, you just blew my mind. I thought you meant they ate other rotifer cells and incorporate the genes in those cells into their own genome, sort of like bacteria transfer genes with plasmids, which would already be weird but I'm reading this paper that says they found bacteria, fungi and plant genes in rotifers and some of those genes were actually functional. So they literally gain genes from whatever they eat, which is wild. Also, I love that they are called 'ancient asexuals' because they have reproduced asexually for the last 25 million years. Thank you for getting me a new obsession!
I wonder if we can make a rotifer that is invincible if we feed it the right genes...
@@Blucario90 Wouldn't it just be a tardigrade, then? ;)
I'm a retired nurse. I've been enchanted with microscopic life since I was a 7th grader and got my first peek into a microscope to see the marvelous little wiggly bits. Rotifers, tardigrades, and paramecium have been my favorites. Thank you for this wonderful program!
I too curl up into a ball when I lack water. It’s a problem.
Woaw make much funny so laughing
Sounds like you have a crippling dependence on water. Please seek therapy.
*Finally I get the respect I deserve!*
Hrn
Rotifer you do you bro dont let those micropredators get you down
F for rotifers respect!
Bro i love you bro please dont give up youre beautiful
You're so mysterious😂
Could you guys do and episode on Microscopic archaeology. How does that even work? Do they have to take thin slivers of rock or something? Or do they like look like in ice cores or crystal inclusions?
Try asking PBS Eons
One of my professor who is a paleobotanist said we have techniques using acid to keep just the fossil pollen from a rock. I assume there are similar techniques for other microstuff
Up
This is my favorite channel of yours by far. There are really no other channels dedicated to the microbial world with such production.
Hi MICO. I love your channel. Can I make a small request. Could you include a small micrometer scale, along with your posted magnification level. It would be very helpful in judging the size of these little creatures. Thanks.
Me: *about to go to bed*
This channel: We'll see about that.
Me right now in Pacific Time lol
LOL.......zzzzzzzactly!
I feel so comprehended and share your situation 😂
I can second this at 1am
it is now 2:30 am in chicago....maybe some of us have succeeded?
YES OH MY GOD I LOVE ROTIFERS I DIDNT KNOW WE DIDNT KNOW ABOUT THESE LITTLE GUYS!!!!! OH MY GOD THEYRE SO CUTE WE FOUND ONE IN OUR LAKE WATER THE OTHER DAY YESSSSSS I LOVE THEM!!!!!!!! PLEASE KEEP UP THE GOOD WORK!!!!!!!!!!
I've never related to something so hard in my whole life...
Stuck to a place sucking food into your mouth and occasionally rolling up in a ball because of "bad conditions"? Same... 😐
Did anyone else feel bad for the rotifer stuck in the purple sulfer bacteria
Yeah, it's something we can all relate to
I felt bad for those tiny critters spinning around and around by the spinny jaws-of-death. Either they got ate, or VERY dizzy. 7:06 especially
No because they do not have a soul
@@michaeldebidart Why not? Where's the cut-off? I agree that some animals are "more" or "less" than others in that department, but from even a tiny little rotifer, we're separated by *degree* rather than by *type*.
A great, great degree. But still not entirely separate.
I have seen remarkably intelligent displays by chimpanzees, gorillas, dolphins, orcas, parrots, ravens, dogs and cats. If I'm required to believe *every* human has a soul - even the absolute dingbats among us who are stupider than a lot of people's dogs - then why can't other intelligent animals have souls? And what hard cutoff separates them from other animals?
It seems more likely to me, that tiny animals with tiny brains have commensurately tiny brains and/or souls. But in the end, they're not so different from us. That's where we - where all animal life began, evolving to this point step by step.
I think no episode left me as mesmerized as this one. Shots like 3:25 are so incredible, how they sense their environment and _switch on_ like a vacuum cleaner. And the little "organs" you can see inside, wow.
Could we get a video on endangered micro lifeforms? How could we even tell if one is endangered?
Just wait for it get close enough to another lifeform, then it will be endangered.
We're all endangered by climate change, overuse of pesticides herbicides antibiotics hormones heavy metals plastics... these guys will either go first or outlive us.
@@marksminis Either they die before us or they die after us. Wow that's deep.
Nature has the general rule; the bigger you are, the more susceptible you are for extinction.
Small animals tend to survive extinction events, especially micro lifeforms.
There is strength in numbers.
@1234 Although you might think that with more generations there'd be more genetic change, that's untrue. Keep in mind that a majority of microorganisms asexually reproduce, so there's not as much mixing of genes. Some of them can transfer genes to eachother, but that's not done with intent or precision, and it's only some of them. With a shorter lifespan, there is also less time for mutations to occur. Quantum physics behaves at the same rate regardless of the overall size of the organism. Much of the microbiome exists in aqueous environments, which is very effective at reducing ionizing radiation, one of the bigger drivers of mutation.
That quote gave me chills, something about the acceptance of the unknown in order to appreciate and acknowledge the beauty of this stunningly bizarre creature for a moment is such a beautiful thing. Not often humans will accept they don’t know things while still respecting and loving it. Thank you for giving the rotifers the spotlight!
I studied bdelloid rotifers for my MSc - I put them in a Mars simulation chamber and they survived it like a champ. Glad to see rotifers getting their own episode!
Human: "Rotifers are often mysterious and bizarre animals"
*Alien: "Humans are often mysterious and bizarre animals"*
*ENERGY BEING: "BIOLOGICALS ARE OFTEN =BURST OF RADIO PULSES="*
fuck we dont even know what we are
Rotifers: "You're both bizarre. And ugly."
Alien Commander: DEPLOY THE TRIPODS!
Rotifers: "Aliens are often mysterious and bizarre animals."
Just remembered Terry Pratchett:
Ankh Morpork Bar customer: "What's in your beer"
Barman: "Rotifers mostly"
I love to come back to this video every so often. The way he narrates is just so soothing and interesting, and the rotifers themselves are so strangely cute, like adorable tiny and mysterious aliens.
That quote at the end made me really emotional and existential, holy hell
yea man. i had a moment, wanted to engrave that quote in my brain
Literally my first thoughts when I saw that. "what is that"
Apparently, that's also what rotifer experts think. They somehow don't know the animal's lineage beyond invertebrate?
What ever they are, they're the Wheel Deal
funni
Oh wheel, it could've been worst.
Wow...🙄 y'all are wheel punny🙄
That's a nice a spin on it.
So clever!
Am I seeing a beating heart?
This is an amazing channel. I wish I had had the smarts to study this but I was always told I wasn't smart enough. I got my first microscope when I was eight. I loved it.! Everything went under my microscope! I was not allowed to go to the pond for specimens so I looked at leaves, pollen, etc. This channel feeds my sense of wonder.
no those are its jaws, chomping away.
My favorite rotifers are the ones that hang out in the leaf lobes of Frullania liverworts. They're so cute.
Oh yes, living creatures from the micro cosmos are so cute 🥰. Also, the microcosmos seems like a terrifying place; thank god we are from the bigger picture
@@airpolygon2714 How do we know that we are not something elses microcosmos?
@@Kiwi_Tea Oh we certainly don't know! I think we might be. It's crazy to think how life could be like in an even bigger picture. Although, you know, physics has all this laws that could demonstrate otherwise if they are right. like the speed of light as a limit to movement velocity
Maybe that explains alien abductions. Lol
God I love this channel, I love how you narrate and share information, I adore the footage and the soothing music. This channel has been blowing my mind and makes me wanna look up more information and find out more about this big little world. Always looking forward to more, and love rewatching to catch the stuff my mind glosses over when I get distracted by wonder and awe.
You are one of the best channel on RUclips. Thank You for showing us the microcosmos.
"The wheel animal in its several postures" is possibly the best figure title i've ever seen
Hank and friend... where do they come from? All these forms of life... you put chlorinated water in a Pool, the desinfectant evaporates and suddenly they appear, airborn? Would love to hear how they get there! Love this Channeo, Sebastián.
>rotifer opens mouth to feed
anything nearby: SPEEEEEN
Vinny No-
I see you're a person of culture as well.
oh no
Microcosmos is my favorite channel, I look forward to their videos the most. I've been watching Hanks stuff for a while, and I absolutely love this shit oh my god
I appreciate your videos and this channel so much. It not only teaches me new stuff I hardly knew about, but it also somehow always manages to make me forget a rough day (at work) etc. and makes me relax. So thanks for that :)
I love that so many people in the comments of these videos have genuine interest and knowledge about this subject ... An someone who has not got a background in the area, I often enjoy reading the moments on these videos as much as watching the videos ... This channel is a lovely pace
Rotifers have become my favourite microscopic animal. They’re just so eccentric and bizarre.
The laid back narration, the beautiful video, and the awesome music...it’s so good.
I really LOVE these videos!
On RUclips there is a ton of videos about animals, but those about microorganisms are relatively rare.
I wish there was more videos like this.
Thank you for your awesome work!
Beautiful little life things. Thanks for letting me get to know the Rotifer. It really cheered up my day
What an great video. Thank you. Thanks, too, to Andrew Wang for these awesome soundtracks!
Thank you Hank, James, and team for this beautiful work of art.
I really want to say that I truly appreciate your Channel! I'm just a simple Carpenter, but still have an appreciation for science. And now with the encyclopedia value of RUclips. I learn about so much more stuff that I never knew I was interested in so thank you. And will on little rotifer!
Beautifully written, fascinating images! This is a real joy :)
Love the new video and the hard work of the microcosmos team. Great work!
This channel is awesome, love the visuals and the narration. Great team.
awesome and fascinating as always!
This channel is everything I wanted to learn and see, without even knowing it. Thank you so much for your consideration for undercover life forms.
Thank you for this wonderful video. Rotifers are amazing. They can even incorporate outside DNA into their own.
Amazing video, the narration alone had me hooked. Thank you for the information!
Colonial rotifers are so cool and so much fun to watch, kind of comical in a way, some of the ones I find have eyespots which lend them a cute 'sock puppet' look. They are cool creatures. They are definitely all over the place, the most common microscopic animal I find in dried moss. Such an amazing video, rotifers are amazing!
Pretty impressive to watch !
Sick beats and the mouth bit looks so weird! They seem to have done really well if there are that many species.
your channel makes me very happy, even if for the length of your videos, it's more than enough. thank you
Wonderful video! I really enjoyed this.
What a joy to discover this channel! Remembering my only conscious contact with this world as a student, trying to draw an amoeba for biology class! This information is fascinating!
Do the lashes on the tip rotate on a fixed point like fanblades, or are they just going back and forth really fast?
Probably back and forth. When going in one direction they are rigid and on the other they flex, so they move water on one direction. At least that is what happens in other similar cases
My brother used to own a Keeshond dog named Rotifer. He chose that name because when he was in biology class, one girl (having misplaced her microscopic sample) was jokingly wandering around the room, looking around, calling out "Here rotifer! Here rotifer!"
I have a rotifer named Kees! Spiders are all Herbert. Ewe's are Stientje.
This channel is the best thing ever, I had no idea I would find this so interesting and mesmerizing. Damn.
I absolutely love the beat of this episode!
Outstanding . This information was key in tying mold spores to my observations over the past six months.
I love this site! So fascinating and keeps getting better all the time, I wish I were much younger as I would enjoy learning and studying these lovely microorganisms !
Beautiful quote at the end. Great video!
Constantly in awe of everything this channel puts out
Oh, thank you! I love rotifers!
Rotifers are so cool, and I love them!
Thank you for making these videos
Wow. Awesome soundtrack in the opening!
Enjoyed this little vacation. Thank you.
I love this channel. These videos are fascinating.
thank you for the captions!!!
Absolute best part of my week!
Nicely done. One of my favorite animals and great nutrient cyclers.
It was awesome learning that these creatures were discovered in the 18th century. Would you folks consider making a historical episode? Covering the early history of microbiology, early microscopes, and showing hi Def footage of the first microscopic cells and animals that were recorded being observed? I think it'd be a unique, insightful, and weirdly humbling concept for a video.
Absolutely fascinating!!
I can usually take or leave most videos with this narrator, but this one was definitely enjoyable. I hope he keeps it up!
Lovely, as always.
awesome! really great footage too
Beautiful videos full of info !!!
When he said 'corona' I really just died a little
so innocent he was, in 2019
I LOVE this channel!
These vids are some of the best things around.
Channels like this make RUclips the great tool that it is.
A particularly charming and visually stunning view of these enigmatic animals. I was looking at all the algae washing past their cilia, thinking how inefficient that seemed, but then noticed that their pharynx, or what ever the analogous structure is called, was full of algae waiting to be processed by the trophi. Hmm not so inefficient after all! I guess disturbing the water to put it in a slide makes it resource-rich in respect of filter feeders. Lovely.
Love the channel keep it up
Thanks for the beautiful and fascinating videos.
The music and visuals on this channel are so symbiotically zen.
Thank you so much for this channel. I've been a microbiological observer for most of my life, and I have found it extremely difficult to get others interested in the activity. Your videos should do the trick.
Fascinating creatures. Love your microcosm series. Would you consider doing a video on the amoeba, one of my favorite protists?
Thanks for explaining this bizarre little beast. It was the second most peculiar, and second fastest, thing my daughter and I saw in our first drop of pond water the other day. In this particular drop the rotifer seemed to be kicking ass. (The first most peculiar and fastest thing, if you must know, was a "giant" shrimp/flea something or other that zipped in and out of the field of view.)
6:10 damn only 40x magnification, that could probably seen as a tiny speck with the naked eye
This channel is a wonderful alternative to apps such as Calm or Insight Timer!
AWESOME, just awesome!! Thank you very much, I've learned something! Beautiful creature, splendid!!
Wow, amazing!
These videos are Awesome!
Beautiful!
It is so weird and cool that there are animals the size of single-celled creatures.
It is also weird and cool that there are single-celled creatures the size of animals.
MFW When I realized they're called rotifers because they have rotary jaws.. 😱
My roommate: "I'm so glad that these cannot grow to be the size of bears.."
