The Didinium: An organic Roomba that seems to be randomly bouncing around the room but as soon as it comes into contact with any other organic, will proceed to consume it entirely.
"An organic Roomba" But what struck me in this video that the perception of these organisms as flat like a roomba is wrong. We tend to see the very short focus of microscopes as showing flat objects, but if you watch, the D is constantly rotating. It is much more like a very short, very fat torpedo than a like a roomba. And the idea of bouncing around the room is too simple as well. The critter is spiralling through three-dimensional space. Awsome.
I remember on my 8th week cell cycle, I wanted to impress the older Rotifers by staying up with them on my birthday. Naturally, we watched scary movies. Also naturally, we watched the scariest movie at the time, Didinium: The Silence of the Paramecium. I was so shaken to my cellular membrane that I ended up staying up for the entire rest of the night. By today's standards, it's a pretty silly cell of a movie, but back then, you wouldn't find my corona anywhere near that film. Simply cilia raising!
Rotifer, what you just wrote is one of the most insanely idiotic things I have ever read. At no point in your rambling, incoherent response, were you even close to anything that could be considered a rational thought. Everyone in this comment section is now dumber for having read it. I award you no points, and may God have mercy on your soul.
How do microbes know what is and isn't food? It's all organic stuff, and they're all decomposers, but at the same time, they definitely avoid certain things and seek out others, and some matter is gonna have less energy in it than other stuff. How do they know?
Well...its like have an inside-out nose tissue for skins, they smell Though they also taste with it so its more like a snake tongue than an inverted nostril
@@peculiarjack617 They have no noses and no tongues, so I doubt they could smell or taste anything, at least not in the sense of that we call smelling and tasting. My own guess as a non-expert is, that they can detect chemical signals from other organisms, maybe their surface proteins or trails of chemicals they leave behind and when those signals read "non edible" the microbes back off.
@@MysteriousAsteria and yet biologists discovered that a catfish's skin is covered in taste receptors making them basically tounge fish, so the same might apply to most, if not all, of the microfauna
I’m an amateur microscopist, and therefore know how much. skill, effort and time is needed to photograph these small motile creatures. Fantastic. 👏🏻👏🏻👏🏻👏🏻
I like how you allow such a fitting company to sponsor you. Seems like a great way for kids to get interested in science early on. The education system is failing. I even want some of those boxes hahaha.
When you said that inject something to paralyze the other organisms. How exactly that is working? Do you it stop the flagella or other areas of the cell? How you can difference between a cell that is paralyze to one that is death?
It depends on the genus. It's usually a protein delivered into the interior cytoplasm by a flexible, extending organelle called an extrusome. The toxin interferes with cellular metabolism, either temporarily or permanently. There will probably be a future episode on this topic, as it is a common form of both protection and predation, and comes in five different structures.
This is beautiful. Like a bloodsucking mole. Watching the microcosm reminds me o watching a finished machine learning A.I that has completed forming its strategy for completing a specific goal. The Didiniums goal is to effectively move and suck the insides of Parameciums. I wonder if over enough microcosmic evolutionary time and generations, Parameciums can come up with a survival strategy to avoid Didiniums.
Found this channel today. Utterly addicted. Learning near stuff. But does everyone else also freak out when some giant organism blasts through frame and also wanna know wtf they are?
I watched a microbe documentary on uk tv in the 90's that described Didinium as a "rogue jet engine" and I haven't been able to unsee that ever since lol
They´re talking about Didinium´s speed and then that Barry Allen organism flashes at 2:51. And at 4:27 that Paremecium just gives up, sort of "Ok, enough of this shit, just do it fast" situation.
The Paramecium are no exception to the food chain they are single celled and hunted by another single cell organism called the Didinium. Its interesting how moving rapidly in all directions increases its chance of finding food.
I don't know the answer, but it's not bacteria it's a unicellular animal; check out their episode about lacrimaria, that one did alternate between rest and predation
it just found and ate something bigger than itself in under 2 minutes real time. Imagine running around in the dark for a while, bumping into, say, a live full-grown sheep, and just devouring it...
I'd like to know what happens to the prey (e.g. paramecium) inside the didinium. How does it digest it? The internal structure of a unicellular organism is a mystery to me.
I’m shocked how much this looks like spore, I didn’t realize how realistic the cellular movement was. How do microbes know what is and isn't food? It's mostly organic stuff, and they're all decomposers, but at the same time, they definitely avoid certain things and seek out others, and some matter would have less energy than others. How do they know?
The existence of these microscopic organisms amazes me, but it also makes me wonder if as significant as we think we are if we are being sampled and studied by greater beings without our knowledge
Can we get a special release edition for election day tomorrow? We need the relief these videos provide! 💆♀️ Actually, on second thought, we probably need videos every day this week...
Hello, I will be glad if you answer what kind of microscope you have the light microscope by the way, I liked the video?👍I am türkish so I may have written messy
Me: "Ah, I bet Didinium pokes the Paramecium and sucks a little cytoplasm out." Dididium "I'm about to end this whole Paramecium's existence with *_THE BIG SUCC"_*
The micro world is as fascinating as the cosmos universe. And more enjoyable because humans can’t go into it and put their destructive boots on virgin worlds.
WTF is that thing between 2:52 and 2:53, it's only in like 10 frames, but it has claw like legs and looks very similar to a bug. Please tell me what that is, it was super fast.
It's like an intelligent HEAT round that fires off a load of paralyzing agent instead of a jet of molten copper which, thereafter, sucks the stew of the crew out including the entirety of the tank.
You know who else is a skilled hunter? The master of microscope, James, following the didinium at 630x magnification
My mom!
Impressive
Haha he really is a master!
Me watching thinking.
3d person view oh God damit fuck slow down yes no stop FUCK if I can hit you I would slow down damit 🤬🤯
And slowed down 500%
"When a _Didinium_ moves, it really moves."
**meanwhile, copepod zooms by and disappears out of frame in a split second**
*My goals are beyond your understanding*

Was hoping someone was gonna identify that. Every time it popped in was like a jump scare moment
Yall saw that daphnia that ran over a larcymaria?

I feel this in my soul
So true...I fell asleep in the middle of this one...now it's early morning and am curious so I'll just start over.
Nothing like some educational asmr.
Man, when I eat a big meal I ain't doing shit afterwards. This little guy chomps down a critter bigger than itself and just motors right on
Well sometimes he explodes lol
To be fair, about half of that paramecium was sprayed all over the place. Still a hungry critter though.

Did this thing inspire the sucking mouthpart in Spore? I can just hear that slurping straw noise in my head.
Yea its called the same thing
Yeah, just thinking about how much this video looks like spore...
Yeah, playing spore, do you remember those guys with 4 pairs of jets with the probuscus killing everyone in its way
ye, but they dont look too much like actual unicellular proboscises (they are varied), more like a mosquito's
@@CrimeVaultUK i think thats called a nosey
You should have a live wallpaper of a slide, would be cool just to watch the small stuff tumble around

Phenomenal camera work, James coming in REAL clutch
It's a good thing all these micro things are micro
2:52 Holy crap, spaceship casually passing by like an alien saucer while the commentator speaks about the weird movement of his organism.
Incredible ! I very much enjoyed the micro and the commercial. Thank for both.
Found this channel today. Utterly addicted. Learning near stuff. But does everyone else also freak out when some giant organism blasts through frame and also wanna know wtf they are?
*It is very worrying to know these ciliates exist.*
Hmm
2:18 that Paramecium will never know how close death came to it
5:27 what is the fascinating twirling organism crossing the left of the screen from top to bottom??
Speaking of Lachrymaria: Didinium will occasionally attack and consume them. That is a big meal.
I watched a microbe documentary on uk tv in the 90's that described Didinium as a "rogue jet engine" and I haven't been able to unsee that ever since lol
That's a perfect way to describe them!
"Exploding from eating too much...", you say! I think I have found my spirit animal.
Hey man, awesome!
Very refreshing content. much needed in these times.
You should do an episode covering how protists coordinate movements of different parts of themselves and respond to stimuli without nervous systems
What is this green microbe that appears in 7:05 in right upper corner?
The perfect video to come back to after a long evening in the lab 😊
They´re talking about Didinium´s speed and then that Barry Allen organism flashes at 2:51.
And at 4:27 that Paremecium just gives up, sort of "Ok, enough of this shit, just do it fast" situation.
Didinium: If I eat another bite I'll explode!
Paramecium: But I'm waffer thin...
Those little corkscrew things at 7:30 are pretty interesting. I wonder what those are.
Oh thank you, I've been trying to remember the name of these little guys for ages!
What are theses ciliate made of and how do they move? Chemically speaking.
Thanks in advance
The Paramecium are no exception to the food chain they are single celled and hunted by another single cell organism called the Didinium. Its interesting how moving rapidly in all directions increases its chance of finding food.
Your critters are the coolest mr James
I think its time for hank and james to make the pinnacle of youtube microcosmos video, the comparison video!
10 fastest microcosmos!
Did you see it check out the long critter at 2:56 to see if it was food?
Weird question, do bacteria sleep? Like after it eats that HUGE cell, does it need some "sleep" or some stasis state to digest it?
I don't know the answer, but it's not bacteria it's a unicellular animal; check out their episode about lacrimaria, that one did alternate between rest and predation
3:49 now that is some impressive camera work
Journey to the Microcosmos
-AWESOME

The fast and the fluidous.
Me: "I'm so stuffed, I could explode lol"
Didineum: "Hold my beer."
5:27 who is that fish? it suddenly came from the top corner of the screen
it just found and ate something bigger than itself in under 2 minutes real time. Imagine running around in the dark for a while, bumping into, say, a live full-grown sheep, and just devouring it...

Are those bubble/droplet looking things inside these cells the organelles?
Wait what is the jelly-like substance that the cell is swimming in?
Are there any plans for an episode on oomycota?
are there any archaea that you guys can take videos off?
Pretty sure most archaea are super small like bacteria, can be hard to see
Didinium is what you get when you mix a humming bird with a honey badger, blazing fast, specialized diet, excelent hunter. Terrifying
So where are they swimming 🤔🤔
even though my teacher plays this in class, i still love these videos
Fantastic! Been since 10th grade… man!

Damn, you can see the Paramecium's membrane rupture as it's being compressed into the Didinium. It would be quite horrifying if it was a human.
which microscopy techniques were used?
They look like wee little echidnas!😍
Somehow the Didinium reminds me of an aquatic Echidna.
So these blind things just exist as long as possible or propel themselves around hoping they'll eventually bump into food?
What kind of microscope is used to record this video?
when he find food he politely backs up and move on? is that what they do?
