Every experiment has to start somewhere. This one began with a container full of dying microbes, and the five cute, pink ciliates called blepharisma that James, our master of microscopes, accidentally turned into a group of cannibals.

Thank you guys so much for this channel!
A very cute tiny shade of pink ! :-)
"I need you all to agree that none of you would become giant cannibals."
Oh, I've learned not to promise that....
Turn into a cannibal they said, it'll be fun they said
Then comes the judging
James is really making the most of his new microscopes. The footage in this one is incredible.
aww thanks!
-James
what kind of microscope is it?
I'm absolutely devastated at the fact I didn't see any blepharisma actually eating each other :(
Same!!! I was looking for this comment 🥺
I have a cannibal like urge to devour more Journey to the Microcosmos content.
Best ASMR channel on youtube. No noises, just calm music and voice and good educational content
Blephorismas: ....
Scientists: Boooo, eat each other! Fight fight fight fight!
These videos have reignited a long lost passion from my childhood for all things microscopic. I cannot thank you enough for the hard work put into research, recording, writing, narration, and editing. Cheers!
I am absolutely fascinated by the astounding variety of species in the microcosmos, which was introduced to me by this brilliant channel...i would like to see microbes under my own microscope, but currently can not afford most of the expensive microscopes with high magnification. Is there any cheap alternative or microscope that will allow me to make observations of these mind blowing microorganisms?
What’s your budget?
Me too... I'm a teen so my parents absolutely doesn't want to spend money on "another of my stupid hobbies"
They did an episode last year on this very question!
@@codachara3256 do you think your parents would be more supportive if you told them it was educational? Microbiology is a science and If you really like it, you could eventually study it or have a career related to it. Microscopy skills would also look great on a resume for jobs like lab technician.
You don’t have to do any of those things, but if your parents are like mine, they might be more supportive of a hobby if they think it’s educational or beneficial in some way.
@@Lilbluepenguin yeah the thing is they saw how I have guitar, knitting and all that as my hobby and they don't really wanna provide me with any more stuff
What the... this is the FIRST video I have ever seen with multiple audio languages, is this a new feature or has no one used it yet??...
this new feature available for few youtube Channels as of now
It took me off guard hearing the spanish audio lmao
I'm a bit tired tonight as I watch this, and so the Whimsy slider in my brain is turned waaay up
So even as I listened to Hank's so-soothing narration
and watched these cute (but somewhat concerning!) critters scooting around
I had a running "background dialogue" in my imagination:
om-nom-nom noises like some slightly demented Muppet monster
the occasional high pitched "EEK" of some hapless smaller being getting caught
Bugs-Bunny-esque slapstick sound effects
escape!
and then back to quiet nom-nom-nom noises...
I know I'm weird and I'm okay with it, but it sure put another layer on the already great video, haha!
Thank you guys! This is wonderful! Footage, editing, and script is beautiful - and your back to the root, let's flaunt speaking skills, lovely Hank, is just amazing! 🥰
Thank you guys! ❤️ lots of love from Denmark 🤗
@Jakob Raahauge . Are you a boy?
@@eddie8096 too old to be a boy
Wow! I'm a fine artist learning medicine, and I must say that these make for very interesting subject matter due to the completely alien, and abstract look of these organisms. Great job in capturing the colors, and form of these creatures so clearly. Thank you.
I think part of it is that some species simply don't differentiate between their own species and other species when trying to find food at the microscopic level. So it might not even be that the larger ones are adapted to cannibalize, but to be able to feed on larger prey in general, which happens to also include smaller members of their own species.
Add a ‘giant pink cannibal’ patron tier to catch them before they eat anyone.
I put this on to listen to a nice, peaceful talk while I drove, and suddenly it's all GIANT PINK CANNIBALS gah!
whoa! audio in both, Spanish AND English! highly appreciated it.
Finally, so glad this is back.
It felt like way too long.
THE ONLY channel I refuse to watch in under 2160p.
I just love the words that accompany all these videos - not only are they informative but also philosophically sweet, on point, true to the nature of life
It's simply impossible to not click on "Giant Microscopic Cannibals". Fascinating as usual.
cheers from sunny Vienna, Scott
A beautiful and fascinating video. I assume that the lens is APO, but I would like to know the model of the microscope and the recording camera, what brand and model they are. My congratulations for the channel.
They did an episode last year on this very question!
As Manikarnika said. They have covered this question, however, I think James has upgraded his scope since then. He uses a Zeiss Axioscope with many different types of Objectives. I think he uses one or two apos, but also Fluorites and a Fuji XT-3, I think.
@@ArawnOfAnnwn, thank you for your answer.
All the best.
Hopefully these questions at the end inspire people looking for a topic for a study or thesis.
One of my biggest issues in school was just figuring out interesting topics for projects, so I'm glad this channel is giving people ideas.
That is likely the reason they include those lines. Now we all want these answers.
But, our planet _is_ completely covered by just one organism.
Soylent Green here we come! 😁
You can look deeper into their genomes and gene expression using single-blepharisma DNA/DNASeq.
So glad you guys are back! Hope you enjoyed the break! Thanks so much!
Interesting video. You can make a separate and detailed video about your microscope. Thanks!
They did an episode last year on this very question!
BIG, SCARY, AND *PINK*
'Oral Groove' is my favorite single mom weekend acapella group.
I think the answer to the question at 8:07 can be hypothesized from 3:09. These organisms could have been forced to cannibalize due to lack of enough food. So natural selection could have forced some of the larger individuals into cannibalism making them even larger.
Ty for posting and updating the playlists 😀😀😊☺
Haa!
They're like the little pink piggys of the microscopic world.... Or maybe the scary pigs like in the Hannibal movie where they eat people but This is microscopic? 🤷♂️
😅👍
Absolutely fascinating, but the some of the descriptions took the edge off my appetite for the breakfast that I was eating...
These videos help me sleep (but in a good way). Very relaxing and calming. Like giving my brain a snack to chew on as I doze off.
Enjoyed your video and I gave it a Thumbs Up for support
Absolutely incredible! Thank you folks for putting this out on youtube.
The big Blepharisma just need some pink gel to make Peace Candles, is all.
The pink ones were so pretty!
This was wonderful and reminded me of the rap we once dropped about nematodes and nematology 🔥🔥🔥🔥❤❤❤❤
So fascinating as always
Just a suggestion, I was thinking it might be cool if you could make a video on micro organism intelligence. Many studies have actually found micro organisms with problem solving skills. It could be a fun topic to look into.
The blepharisma get to shine in another episode of their own
perfect watch before a stressful meeting :D
Perhaps it's simply Nature adhering to the ancient proverb 'Don't put all your eggs in one basket'. Whilst the flask might be an optimum environment for the ciliates concerned, they have no way of knowing that those conditions are going to last. If the populations of bacteria suddenly crash, then the bacteria eating ciliates will begin to starve, but if some of them have become cannibals, they have plenty of food and will continue to thrive. Then, when the population of bacteria increases once more, they can divide into smaller ones to take advantage of the renewed resource...
Perhaps this is too simplistic, and obvious, and doesn't really answer the question, but what I've learned through life is that, sometimes, certain matters don't get answers until long after the question gets asked... if they ever get answered at all!
i am astonished by hanks range, ive been watching the tiktoks for months and the pbs shows for YEARS, this channel since it debuted but only realized a month ago that this voice is hank.. and only because he plugged something in his pbs voice...
Thank you for your work, your channel is truly exceptional and one of a kind
The closeups make them look almost like they are wearing jersey knit "sweaters" 🙂
my favrite one right hear
Yet another particularly remarkable episode.
It's a pity you weren't able to catch some of those cannibal Blepharisma eating others (given they were indeed cannibals of course).
People, don't leave your socks around !!
They're simply gorgeous!
It almost feels like an adaptation for emergencies, food is extremely low? become huge and eat your relatives, then divide into many smaller ones, hopefully the conditions will be better by that point, better have a few very big ones survive so they can reproduce later, than having everyone die, kinda like owls eating their chicks. Fascinating!
They look like squishy pink knitted sweaters.
I'm fascinated watching microscopic organisms eating. Even cannibalism when presented. Thank-you so much for teaching us about these creatures.
Yeah I think this is a new favorite.. stentors were first for a while
8:22 my guess, it's an active adaptation to the size of typical food. If small food is plentiful, eating it directly is most efficient. If not, it's best to have some of the population adapt to eating larger food. And if small food is extra scarce, anything too small to eat the bigger food is a waste for the species, and best recycled into better-adapted larger organisms.
Size might also be good for efficiency. The smaller your surface area -> volume ratio, the less you can eat, sure, but also the less you need to deal with the outside. If there isn't much to eat regardless of size, getting an evolutionary edge means using what little food there is more efficiently. So the same amount of biomass might be better used as one large organism, than two smaller ones.
It might also be a way to consolidate the species's biomass onto a few more successful genomes - if a blepharisma manages to get big, it's probably been doing something right at every previous size, so putting its genome into the rest of the species' biomass makes sense. And the simplest way for biology to do that, is to eat less successful organisms and then divide. Importantly, this can still happen if the most successful genomes happened to just be lucky (rather than high quality), since they'll be the ones to spread across the species.
So many people say cannibals, but never hownibals, or whynibals.
Thank you-very informative well narrated and put together video.✌
Yess
I've often found it miraculous that any simple organism doesn't at least try to eat its own. All organisms are made of food. I know there are surface receptors that can help even unicellular organisms figure out what's in their mouths, but as they diversify and speciate, the receptors and the molecules they recognize are never going to mutate concurrently in lock step. It therefore doesn't make sense to whitelist your own kind; that would be too fragile. But it also doesn't make sense to commit to particular target surface molecules that you don't have because then you are fragile to your prey's mutations and can't expand into new or changing environments that might not have exactly what you're looking for. Isn't the most sensible strategy, then, to at least try to eat everything that's made of food, i.e. every organism including your own species?
I'm _not_ underestimating the complexity of microorganisms. I know the wealth of information inside any cell in depth. But recognizing, say, a feature of an external cell bigger than a few proteins would be not only extraordinarily complicated involving a huge network of messenger molecules, but also highly brittle to mutation of either the predator or prey.
Reducing food supply is a good way to see changes in behaviour. Now I want James to take 15 of them and start 3 new flasks with 5 in each. One is the control flask, it gets the same mix as the original. One is a flask with half the food of the original. And the third gets one quarter of the original. Please let me know the results!
My guess would be that with an exponentially growing population, even with seeming abundance, resources start to be used up. And as you said, when the cute pink cells divide, they create smaller versions of themselves. Smaller ones that can then be eaten.
"reducing food supply is a good way to see changes in behavior" - my mom using food denial to improve my grades and compliance: 👍😏👍
A Study in Pink
The name of this Sherlock episode came to mind while watching this.
Oral Groove was my nickname in college
Some of your descriptions, well let's just say they brought back memories. Wonderful videos and commentary. I will say though I'm jolly glad my wife was not so prolific. Or me come to think of it.
describing 5 microorganisms as a "handful" is funny to me. All 150 million would also be "just a handful"
Are there any experiments where cannibal microorganisms show a preference for or aversion to their own kind? I can imagine that as it's driven by food being scarce, that if given the choice of a smaller Blepharisma and another microorganism that it can eat, it should on average eat the other microorganism first. That does make me wonder, how do microorganisms tell each other apart? Intuitively it has to do with chemical receptors? But if it's known, I'd love a presentation of literature.
Woah dude. I wonder how many replicated, ate their clone, then split again.. That's some crazy reincarnation.
I don't want to offend you but You have a nice voice, that make me fall asleep 😂
do these microorganisms just move randomly? How do they know to distinguish between prey and something they don't want to eat? they don't have a nervous system right, so no eyes, no sense of smell or anything else? or thought for that matter...
Possibly a way to reintroduce genes and such.
occasionally they have a cannibal phase, and then split.. I am not a pro, just wonder alot!
Hank channeling Welcome to Night Vale in that outro....
As they reproduce through cell division, this sometimes cannibalism almost seems like a cancer.
"But cannibalism... demands more."
*How can I make my own environment with microorganisms for observation? Or find it?*
Get a small sterilized container and put some kitchen jelly that you previusly melted down in it, let it cool down and then just put you fingers on the jelly and close the container. The bacterias you had on you finger should grow and form mould-like structures
Fue tan extraño entrar al vídeo y escuchar que estaba en español... Me confundió tanto que revisé si era el canal original jajajaja
Iso (buddi)
Not so different than us. As history has evidenced; We all need to feed. I’m gonna start with my cats; Then, damned be Prionism.
Welcome back.
So.... no one's gonna talk about how the Blepharisma in this video look like lava lamps...?
Wow awesome video!
That... was somewhat gruesome, but I guess nature really doesn't play around.
different languajes? how long has that been a thing?!
I didn't know andrew huang made the music???!
"But those grains were not there to feed the blepharisma.
They were there to feed the other hidden residents of the flask, the bacteria, expanding their numbers to create a buffet for the blepharisma to eat."
Those grains were there to feed the blepharisma.
Kirby is that you?
There are probably planets that disappeared because the life there learned to eat minerals alone.
this was amazing!!
Do they even know they are eating a brother? Could they know?!
Science used to say that smaller brains equates to less intelligence, but I noticed, while playing the video on mute, at 00:40 to 00:50, one of the Blepharisma actively seek out, and find, a partner to joint it in a dance. If that's not a display of intelligence, I don't know what is. See for your selves.
8:35
Literally "biopoetry"
Let’s see what this one is about
There's a sci-fi horror story in this...
Tnx for spanish audio track!!!
@7:02 on the right bottom corner theres totally a face on the screen.
No entendía lo de la voz y pensé que me había confundido de canal 🤣🤣🤣🤣
So this is how a Kirby infestation ends, huh?
Humans have an oral groove too, as a whole ours are located in our face.
How do you make your blepharisma soo pink?
La pista de audio en español me tomó por sorpresa 😁
hmmmmmmmmmmmmmmmmmmmmmmmmmmmm.........
interestin.....how nutritious is blepharisma enriched water
They are cute though.
