- Pardon my French but Merlin's smelly pants, what a scene! And it's in real-time!!!
.
Didinium is a vicious hunter, it has a arrow-head like cell mouth where it attaches itself onto the prey, releases toxins to immobilize it and opens its mouth wide enough to swallow the whole organism.
.
You can see in the first clip that there are needle-like structures appearing after Didinium touches the Paramecium, those are actually coming out from the Paramecium, they are called the trichocysts and they work as a defense mechanism for the paramecia. Paramecium usually able to repel the attacks with them, the trichocysts ejected from the cell membrane so fast it pushes the attacker away, don't let the predators to get good hold on the prey. Fascinating isn’t it?
.
This is just a single example of prey and predator interaction out of millions you can find in the microworld. I hope you get my fascination about all those things better now? - Наука та технологія
My head has invented the noise that a Didinium makes when it vacuums up its victim and it was very unsettling 😳😳 Amazing video!!!
Like slurping spaghetti huh.
I thought of a vacuum twisting the wrong way and sucking in your pants making you trip and fall.
So weird I get that with insects all the time
I heard it like this
Didium: (spinning in circles) WHEEEE WHEEEE
Paramecium: doo-dee-doo doo going about my day.
Didium: hey cool - lunch
Paramecium: augh! Bro, wtf! Get away from me!
Didium *vacuum noises*
Didium (again spinning around quickly) WHEEEE WHEEEE WHEEE.
Yo those spore mods are really impressive holy shit
I like how it does victory laps after the successful hunt
It looked to me like it had Paramecium rests on his mouth, which he couldn't eat up and therefore tried to wipe his mouth on stuff to get rid of the food
Bro emoted
I know this is literally what happens but it's so unbelievable that single cells can do such (seemingly?) complex tasks.
step one to wondering whether "you" is a "single" organism or a "colony" of multiple organisms working together, like those creatures in sci-fi
Don't you hate when you've swallowed a paramecium too fast and get the hiccups?
If you think about the fact that we might went from single celled life, to multi celled life in a situation like this its even more mind blowing.
That's not a fact. It's a theory. And an obviously wrong one too.
@@vickymarinou6271 bruh he said, “the fact that we MIGHT went from…”
"the fact that we might went from..."
That moment when atheists cringe under a gigantic face palm😄
@@Rick-the-Swift Supporting the theory of the evolution of species does not imply being an atheist.
@@philosophiaentis5612 True, but even so I bet atheists cringe and facepalm more then non-atheists when evolutionists start their sentences with, "the fact that we might went from..." 😆
Damn these little dudes *GO HARD.*
You realize how connected we all are.. With each movement this thing makes as it prays and digests, the plasma all around it reacts - even in the smallest of ways throughout all corners
Are you suggesting this thing is religious? Hadn't thought about a tiny being like this praying, but you know what? Maybe it actually helped it get some food. 😊
@@confused_gaymer1868 Ah. So you both mean prey, instead of pray.. Gotcha☺
@@Rick-the-Swift yep, why not.
Cellls swallowing other cells created more complex cells, for example mitochondria were swallowed by rudimentary cells and did not die but reproduced in those predatory cells. Which lead to an evolutionary advantage. There are about 1000 to 2000 mitochondria in human cells so every cell division they were shared. I guess it could happen that one cell didn't get any but that would have lead to death.
Thats what i was thinking, evolution is wild dude.
I love how its body goes conical from behind as it eats, it allows it to easily back up and then swim forwards to stuff that paramecium in its guts, very economic
fascinating
thanks for uploading this
I love the bodyparts it uses to move - they look like little insect wings. How furiously they flap when it latches onto its prey. I can almost hear buzzing in my imagination (it's the one thing microworld seems to lack - sound)
Technically, they don't lack sound. There is vibration in water, so there is sound energy. We can calculate that amount of energy, but I doubt we can put a microphone sensitive enough to listen to it. What we can do is from the image, analyse the 'flaping' frequency and reproduce that same sound. We can even adjust for the water being denser than air to get the proper sound.
@@alexandrevaliquette3883 what would the "sound" even mean here... we associate the concept of "sound" with subjective impressions produced by the nervous systems + hearing apparatus of creatures with a hearing sense, not just the existence of physical sound waves. The "sound" produced through means you describe would be a "sound" no creature ever heard or, more importantly, will ever hear. It seems like it would just be a purely artificial construct, because the sound waves coming from the speakers would be fundamentally different.
@@Medytacjusz It doesn't matter if this sound was ever heard or not. (maybe some microorganism can feel it?).
I think we can shine a laser and record it's reflection with a sensor. This will get a very accurate record of theses vibrations. Then, you play them back.
It's around 20Hz, many vibrating 'hair' at the same time. So, basically, a very very low pitch white noise.
@@alexandrevaliquette3883we can transform all sorts of data into audible sounds - but what for? it is pointless because it doesn't tell us anything. It's like that video that was going viral some time ago about "the sound of stars".
@@Medytacjusz There is a difference between pointless and false.
I have not watch that video about "The sound of stars", but I will guess that they alter the frequence to adjust to the human ears. It's a little misleading, I agree, but some folks like the artistic stuff. So, not totally pointless, but not a true reproduction either.
On my side, the sound of ciliate/microbe can be reproduced, without too much transformation at the same frequence of the real thing.
After calculation, I realise that it won't be a high pitch sound, but a very low pitch sound around 20Hz. Like a thousand very large and slow fan + very low pitch white noise. I think it's quite fun to figure that out isn't?
The real frequency can be precisely mesure analogically with a laser and a light sensor. An easier way, but less precise would be computer image analysis.
Note that I only consider the hairs flapping in water for the generation of sound waves. I don't pretend a motionless bacteria is emitting sound for example.
My background: analytical instrumentation.
Great video !!
I'm gona name my dog Didinium
It's like a proboscis from the Spore Cell Stage
Really great video❤️
Beautiful
absolutely fascinating, can I just get a microscope and witness this awesome action myself? I'm fascinated by this and want to learn and explore more!
Sure, you just need some pond water and patience
And a microscope 🤔
Awesome 😎
it's a one-germ eating contest. & he's still looking for more!!
Where and when do you get these samples?!? There are so much things to see!
What a nasty realm we exist it. Everyone eats another one
Yes! Mmmmmm!
It could be nice to reproduce the sound they emit in water.
There is vibration in water, so there is sound energy. We can calculate that amount of energy, but I doubt we can put a microphone sensitive enough to listen to it. What we can do is from the image, analyse the 'flaping frequency' and reproduce that same sound. We can even adjust for the water being denser than air to get the proper sound.
🎤🔬I just put the video in 0.25x and calculate roughly 20 Hz (20 flap/second). This is the lowest frequency that humans can hear. If you play that sound in very large speakers, it will mainly be a chest vibration more than a sound.
Maybe during the 'victory dance' at the end, the speed is a tiny bit faster and we can hear that extreme bass solo!🎸
To replicate the sound, take a regular 52 playing card deck, and flip it in 2 seconds. You will get 25 Hz, if you go a little slower, you will get the sound of an happy Didinium!
Hey I would like to ask what type of microscope do you have to view this and how to u find these micro preditors
Excelente!!!👏👏👏👏👏👏
Невероятно! Совсем как тигр, поедающий добычу.
This looks so much like the straw thing in spore
Problem is it isn't green.
With all that junky detritus floating around, I thought for sure there would be a Pacman critter gobbling it up.
ohhh wow how crazy cool to see! scary lol but incredible!!! 🔥🔥🔥🔥
*They both have souls.*
Paramecium soul just got rekt
What sort of water is this and what microscope are you using.
where do you find these microorganism?
What a swing
lol its like HRR HRRRR HRRRRRRRRR HRRRRRRRRRRRRR GET IN MY BELLAY
also thanks for posting exclusive content here before hank gets his hands on it with less editing, just awesome raw footage :D
What a savage. Forcing its victim into itself by violently swimming around like that.
This is absolutely brutal. That thing is a nightmare of the microscope world. Imagine living in a pool with a monster 10 times faster than you and can devour your entire body with a minute or two. 😮
Wow!
the darkening around 38seconds in, what could this be?
Now this… is epic
Any algae with that, sir?
The new spore looks sick
amongus
Poor little guy
it’s trying to force the contents of the cell down it’s tiny gut through movement
Thats like being able to open up your whole head to stuff an entire cow in there at once? The cell membrane must be super stretchy.
Would nano filaments inside of cells be a good topic for Microcosmos?
Yes
That was gruesome
That was just dinner, why is it gruesome?
@@cee8mee joke
Rip
hi, I was wondering what is the price range of a microscope that I should buy to be able to observe organism, or a telescope recommendation
anywhere from nearly free to more than the house you are living in ;) but if you can find a used 1 from someone who just upgraded, you can get them cheap sometimes
Ebay !
@@yesihavereadit been selling on ebay since i was 13 years old! goodwill is a wonderful place to find a cheap micro or telescope
Didiniums are cool
eat it, just eat it...
cool
Interesting, i saw Tartigrade in a microscope.
belly full head empty
Life is harsh
Are we certain about whom ate whom?
The predator couldn't even eat it up. So sad when poor Paramecium guy started to lose its hair.
Which medium to you look at? Like what kind of fluid is it and where did you collect it?
Most likely a petri dish , but then again , I don't think petri dishes have plant life
Most of his samples are from pond water.
@@rustyshackleford9888 Thank you, I kinda guessed, but it looked so more viscous than regular water, that's what made me doubt
@@petrescuework-difficultcas6581 water behaves differently for life at the microscopic level. Life that small has a much harder time overcoming the cohesive properties of water, compared to large, macroscopic things like us that easily displace water. This is why it appears more viscous, even though it's not.
@@rustyshackleford9888 Thank you for the explanation. I only looked at things like bacteria, funghi and body cells at University. We never had microorganisms to look at irl, just on pictures.
this is brutal omg
How often do they need to eat a meal like that?
If they can find a meal, they eat every 20-30 minutes or so!
Do you use stain for watching them ?
I believe this is just DIC microscopy without any stains. He also does the microscopy for Journey to the Microcosmos with Hank Green, and they have a video from ~2 years ago talking about their setup when they got their new DIC microscope.
People named Jam : ...
That first part looks a lot like me trying to suck a fresh milkshake through a straw.
💯
That is kind of unsetteling
Circle of life
will he be ok?
yeah, it's just nerve gas
Can cells get pregnant
go grandpa
The dirt really had to censor it 🤦🤦
HE EAT HIM!
Lo que parecia un casa de vidrio rodando era una diatomea
With no brains, his do they hunt? Hunting takes intelligence, decision making, right? Maybe we just don't understand yet?
Quisiera saber horrible 😩
🎵🎤🎧To replicate the sound (about 20 flap/sec), take a regular 52 playing card deck, and flip it in 2 seconds. You will get 25 Hz, if you go a little slower, you will get the sound of an happy Didinium!
To be more accurate, you will need to mix it many time to get hundred of layers (to mimic all the vibrating hair).
Basically, a white noise at a very very ultimately low pitch. Niagara Fall for a deaf person.
Forgive my ignorance ... but does this take place in human/animal body's ?!
It’s my understanding that what we’re looking at is pond water under a microscope.
@@christopherjohnson2422 thank you
@@555tracy both of these ciliates (Didinium and Paramecium) are free-living in primarily freshwater environments. There are no known infections/diseases caused by them. If you were to accidentally swallow some will swimming in a pond, they would just die in your stomach.
@@rustyshackleford9888 so....... the predator can become prey to a bigger predator? wonder how they taste
@@rustyshackleford9888 I'd like to correct you , Paramecuim causes malaria in humans . , it's often transported to our bodies through mosquitoes
pls do something big
I stopped at 30 seconds because it's kinda gross. The human equivalent is a 500lb man eating a supersized McDonalds meal lol
We are watching life how it was 3,5 billions years ago.Do you realize that ?
this little organism has been breeding and evolving just as long as you have, it is far FAR more advanced than related species 3.5b years ago or gigayears if you will
@@frogz I know they 've been evolving ever since,i was trying to say that this is a glimpse of life on earth when it began and the first predators appeared,single cells eating other single cells.
@@valevisa8429 the ciliate lineage likely split from other eukaryotes ~1 billion years ago give or take a few hundred million years, with the oldest identifiable ciliate fossils found being ~700 million years old. So they definitely don't reflect what the earliest cellular life from 3.5 billion years ago looked like, which was likely bacteria-like. And most modern ciliates evolved within the last few hundred million years, and are now a diverse group of eukaryotes. For example, the Didiniidae family that Didinium species (one shown here) and related Monodinium species belong to, likely diverged from other ciliates ~400-500 million years, about the time when the first fish began appearing in the fossil record during the Cambrian explosion.
@@rustyshackleford9888 OK :)
Nom
Está acontecendo dentro da pele ou dentro do intestino? 😳 Uau
They should call this cell the x wife
Greedy pirate！！！！

now wtf
F
Imagine if they could see all this when they were writing the Bible.
Have you never Read Genesis ?
God made Everything if you Read it , whether you Believe it is your Choice , we all have to Decide.
There has to be an Intelligent Creator , Nature is Too Perfect
To me if you believe in Evolution then you are not in Tune with Reality.
We Only learned about a Hundred years ago that the Male Rib is the only Bone in the Body that can Regenerate itself !!!!
So how did the Bible know that from thousands of years ago , it's Impossible
What a glutton!! Even the microscopic world is cruel and selfish. When I think of innocent cows and steers being slaughtered unnecessarily to feed the appetites of some humans, I wonder if we have evolved at all. (Amazing video, though-thank you!)
this is what my ex wife did to me
