Imagine if giraffes actually behaved like Lacrymaria. You're visiting the savanna, there are pieces of animal gore everywhere and suddenly a Giraffe whips it's neck between trees, bushes and rocks to eat a hippo or lion alive by swallowing it whole, it's neck stretching like a sock around the animal as it struggles to escape. I'd like to see Junji Ito make a story about that.
That was very low-brow and unscientific terminology that I found to be superfluous and offensive. I will be reporting this video and this thread to Facebook.

Hey james, thanks for your amazing work! Quick question: In this footage they seem to not attack and try to eat each other, is this an actual thing in their behaviour or this "sociality" is just random luck because they're not able to actually see/sense each other?
James you really should be proud of yourself man, you're spreading love and wonder for science far and wide with the proliferation of all the gorgeous imagery you produce.
imagine a macro-sized animal using lacrymaria's hunting method though a long tounge or tentacle that probes the forest floor looking for prey to ensare and drag back to the main nody of the aninal
I mean about as close as I can think is an anteater, and to a lesser extent chameleons. And in a way I guess you could say snakes? So I'd say if you take the long tongue hunting method of an anteater but made the tongue a 10 foot long snake that could eat it's prey whole, as lacrymaria and snakes can do, then you'd have it!
@@netsch20 The first thing I thought about seeing the lacrymaria was a cone snail. They also use a tube shaped protrusion, and use it to inject venom from it after finding a target. Maybe not a vertebrate, but it's definitely a macro sized animal with a very similar method of predation (and defense).
Lately, I've been contemplating the idea of a D&D campaign set underwater, with all amphibious player characters. Watching this video, it occurs to me that populating the oceans with giant bacteria - macro-micro-organisms, if you will - would be an interesting way to add variety to the campaign. As well as danger. A Lacrymaria the size of a horse would be a frightening thing to face. Its "neck" extending and coiling around corners up to 100 feet away. Probing coral reefs, sargassum clumps, or the halls of some sunken dungeon. Its attacking poisoning and grappling PCs, and trying to drag them back to be enveloped and digested.
You could also think about shrinking the characters. An adventure in a drip of water with playable water bears and rotifers and "giant" plankton bosses would also be interesting. Or do both ^^
I seem to remember an old Dragon Magazine article that had stats for a few of the microscopic beauties in a larger form. Can't remember what issue though.
And this thing is unicellular, meaning not only does it not have any muscles to move around and attack prey, but also no nerve cells to coordinate the motion.
Great example of how evolution rarely invents new things. Most things an animal cell can do are just specializations of something microbes already figured out.
@@LimeyLassen Don't forget the unicellular stage lasted 2.5 billion years, multicellular appeared 1.5 Billion years ago. The basic of life were well established when the first animal appeared.
Hank, I know it's too late, but I didn't know this channel existed until you mentioned it shutting down in your latest video. I'm enthralled, and will be making my way back through these videos. How fascinating and beautiful. I hope the videos stay up, and maybe sometime in the future, it will be the right time to reinvest in this idea.
What amazes me most about microbes is how they're able to move and hunt for food with no brain and relatively simple bodies. This Lacrymaria with no brain is able to randomly hunt for food, has a sense of time and knows when to rest and when to hunt.
Indeed, and I am very happy that something like that doesn’t exist in the world I walk around in daily. Imagine some sort of terrestrial Bobbit wormof 25 m long...
This channel is actually helping me study my Introduction to Cell Biology course. Seriously, keep it up! My GPA depends on it (JK, but it does help). Also, it's such a soothing channel, when I'm not being pulled into the drama of the microcosmos, which I love. Definitely one of my favourite channels on TH-cam!
I cannot imagine anything more terrifying than the concept at 4:37 - a predatory megafauna with no prey selection, no persistence but high efficiency; where no matter how quickly you move, how little noise you make, you stand just as much chance as any other living thing around you at any given moment of a gigantic neck whipping out from god knows where, taking a bite out of somewhere, anywhere, on your body, and then just leaving you, bleeding and helpless, for scavenger species to finish off. Absolute nightmare fuel. But, probably also driving a healthy ecosystem.
Today my daughter and I were looking at some standing water we took from a flower pot in our yard and we mostly saw these. They weren't listed in the booklet of microorganisms we were looking at, so I came to this channel to see if I could find what they are. This is so cool!
That's amazing! I came here from DDOI, and I think I'll stick around. You are a fantastic creator, and those microscopic creatures are amazing! It makes me wish I had the resources to make a little tank and just watch what slithers, slides, glides and swings by.
This is on of the most fascinating content I've seen lately. Please dont stop making videos, I was always interested of the Microcosmos and you're fulfilling my childhood dreams. Thank you.
Ah, another microorganism I had no idea existed, but now I do and it’s SO cool and interesting! Just more to learn. Watching this is better than the nap I was going to take.
This is the second video I watch after finding your channel... I'm fascinated by this new world I'm getting to know in a different way, and looking forward to watch the rest of this beautiful channel
first of all WOW! one of the best episodes; wish we could zoom in even further on that first eating scene, and even play it slower so we could see the other organism merge with that of the Lacrymaria. Thank you.
Impressive shots of an impressive organizm!!! 2:00 I love how we can see the spiral texture on its surface, probably it twists in order to elongate or shorten itself.
You guys (and your new microscope) are amazing. These videos are entertaining as well as educative. Devoki, thankyou for your awesome choice of words and expression.
we take movement like the lachrymaria's for granted among animals, but how the heck is it changing its cell size & dimensions with such rapidity and repeatability? Is it actually building & destroying microtubules? Using some sort of muscle analogue?
I think a game where you take part in this micro ecosystem would be fun. Like people trying to grow and survive as a Tardigrade and multiple other creatures.
I was watching an amoeba eat a paramecium almost as large as itself in biology class in college when I noticed the paramecium developing cracks in its outer membrane. Shortly thereafter the amoeba stopped moving and began to rupture and release grainy fluids. When I was sure they were both dead I asked the instructor what was going on. He asked how long I'd been looking at the same slisde and I said ten or fifteen minutes. He said "When they do that, it means they're done." As in "The food is done." The slide got so hot under the lamp that it cooked them both.
If what I'm seeing, less guppy like and more corkscrew/syphillis like (just looks side to side because flat) Don't know what kind of thing it actually is though, seems too big to be bacteria
Despite all that, I am still more amazed and taken aback by the slow, gigantic, mindbogglingly well structured rows of algae floating by, oblivious to everything.
That music change at about 2 minutes in was BRILLIANT!!! And these critters are pretty dang interesting indeed :D I do agree though, if giraffes had necks like THAT - and left a wake of dismembered victims - well let's just say I don't think even poachers would risk a safari anymore!!!
This is amazing to watch. Seeing predatory behavior like this with a single-celled organism is incredible. It makes me think of every bit of water as a micro version of the African savannah, as it's compared to in the video. So much action in places I used to consider boring.
What is so odd to me is that these microbes have ”parts”, like not just organelles, but it has a clear ”head and neck” that doesnt just disolve into the main ”body”. How the heck does it work? More plz.
A noteworthy fact about Lacrymaria. It has no nervous system. It certainly appears to exhibit pretty complex behaviors, searching, hunting, eating, responsive movements, sensing, etc. But, no nervous system, no brain. In my mind this brings into question the dogmatic belief that BRAINS AND ONLY BRAINS can generate consciousness. If Lacrymaria interests you, check out the work of Michael Levin of Tufts University. His 2018 NeurIPS talk, (on youtube), "What Bodies Think About; Bioelectric Computation Outside the Nervous System," is fascinating.
It's not dogmatic at all, it's just ignorant and dumb people tend to assume that they are one of a kind special and by extension that everything else is inferior. Of course you don't need brain cells, you only need any kind of mechanism whatsoever that operates by some defined set of rules - with the right set of rules it will produce intelligence.
I appreciate the comments Mi and Osmosis. I will admit though, that I had a much different train of thought in mind than what your responses hint at. Mi, I want to point out that I make a big distinction between consciousness and intelligence. Also, I'm not quite sure what you are alluding to with, "you only need any kind of mechanism whatsoever that operates by some defined set of rules," maybe you can unpack that statement a bit. Osmosis, I agree with you absolutely, the brain is not a computer, even if we might be able to make some strong comparisons to the functioning of computers, and the the functioning of neural systems. It is an interesting idea to think of individual neurons as computers themselves, (you may want to check what Dan Dennett has to say on this, it reminds me of some of his arguments.) However, I don't think the brain is a computer, and I don't think neurons or any biological cells are computers either. From my positions, life and biology, are in a different category from human imagined and designed systems. I don't believe that humans can inject the "right stuff" into any system which will render it truly alive or conscious. Well, ignoring the obvious example of human reproduction itself. I'd appreciate hearing both of your responses if you're willing to take the time to respond.
@@S.G.Wallner Human intelligence and consciousness comes from billions of neurons operating by simple rules, and it's the specific rules and specific arrangement what makes it produce intelligence - not the number and especially not them being neurons specifically. Anything that exactly replicates neurons can exactly replicate human brain, it could be something as simple as molecular engine operating on individual compounds, or it could be analog or digital logic circuit. Moreover, it doesn't need to replicate human neurons specifically, it could be any abstract set of rules (e.g. Convay's Game of Life produces pretty interesting effects out of just 2 basic rules) it just needs to happen to be the right kind of rules to produce intelligence. Us humans have this exact set of rules embedded in DNA because every specimen that didn't, died off - only the good samples made it to this day, i.e. the evolution specifically selected for these rules out of trillions of random possible combinations, and as you can see in the video the same happened in a single-celled organism, to the extent that it was useful and/or feasible to accomplish. If you put artificial neural networks in a simulation with selective pressure for intelligent behaviors, they eventually become intelligent. Now, to go from scratch to human intelligence will require billions of years worth of simulation and simulating billions of neurons isn't exactly speedy operation, so nobody's doing that kind of sand sifting to find the kind of artificial rules that can create artificial intelligence - but we might eventually, just for kicks. It's currently pretty obvious that just a big enough natural language model can effectively be an artificial intelligence with human-like capabilities, we don't actually need to have the real deal because we've figured out how to make fake work just as good.
This goes a long way to illustrate the universal "Principle of Correspondence" which means that what happens on a large scale happens on a small scale and vice versa. Just like animals have to feed, rest, multiply and they have special organs for each of these, so do these small single-cell "organisms", just at a smaller scale.
@@tammcd What an anti intellectual way of dismissing a point you don't like 🤣 You don't know anything about science or Medicine so stop trying to sound so smart. Science and medicine doesn't disprove intelligent design, it does the opposite actually.
The r/atheism user woke up groggy next to his 6 pack of empty Mountain Dew cans. He lifted his 400 pound frame off his bed wondering how many women he’d be able to harass on Xbox Live today when just then he remembered: today was the day. Today was the day he would finally get a chance to debate Christian sheep and slay their god in heaven. Excitedly, he got on his disability scooter and then into his 2007 Toyota Corolla. He drove to the hospital, scoffing every time he saw a crucifix bumper sticker and made sure to situate his fedora before he got out, parking in between two disability slots. When he entered, he got his camera ready, and going up to the third floor he thought “Reddit, the last enlightened place on Earth, will finally give me the attention I deserve and recognize me for my intelligence.” He entered into the room where his grandmother was lying and drawing her last breaths. A priest was standing next to her along with her children and grandchildren, anointing her and hearing her last confessions. “This is it,” he thought, “this is where I own those religiotards and achieve victory for atheism.” He boldly walked right next to his grandmother’s side and just as the priest said “may God bless your soul,” he bravely rebutted with “but there is no god to meet you in heaven. None of it is real. Your sky daddy won’t save you this time.” His grandmother looked on him in shock, opening her mouth. But then she slouched and a long beep was heard and her mouth remained wide open. “Yet another victory for atheism,” he said, looking at his family members who were stricken with faces of horror. “I’m sure they’ve finally realized their God is dead.” He opened Reddit, excited by the prospect of the karma he was going to get by posting the video he took on r/atheism.
There’s something about the way these ones move that I find really unsettling. It’d be an excellent monster in a movie, crashing around a city and thrashing about its horrible neck thing.

Another amazing creature beautifully portrayed. I’m not from the US but I find it great that you are referring to videos that explain people how to vote. In many countries voting isn’t mandatory and so there is the chance that many citizens don’t have the chance or the information to make their voices heard. Participating in the vote is taking active part in the government of your country. Don’t forget a lot of good men and women have given their life in the past so each of us can now make our voice heard. Vote, it’s your right.
It's an interesting strategy. For a single celled organism. If it takes too much energy to be fast. Make part of yourself fast, and connect it to yourself with a tube. So that it doesn't get lost, and it can pass food to you.

THANK YOU HANK FOR THE PLUG AT THE END! HAPPY TO KNOW YOU CARE ABOUT THIS COUNTRY'S WELL-BEING!
Superb clips, super music, and super narration.
Love your amazing videos! :D
The microscope puts up better quality than vertically-filmed videos on the internet.
I've been wondering what these necky weirdoes are in my slides for a while! Thank you so much for this video!!!
What is that creature spinning around at 2:14 ? It looks like it has chloroplasts in it but I've never seen that before
Its like a microscopic Elasmosaurus with the attitude of a tiger who hasn't eaten in a couple months.
This is the wildest one yet. So glad there are no macro-Lacrymaria.
Where's Mr. Rotifer? :(
I suspect he's being hospitalized from being assaulted by one of them.
Interesting creature. Bravo for broadcasting voting info.
this account is so relaxing. great content.
A noteworthy fact about Lacrymaria. It has no nervous system. It certainly appears to exhibit pretty complex behaviors, searching, hunting, eating, responsive movements, sensing, etc. But, no nervous system, no brain. In my mind this brings into question the dogmatic belief that BRAINS AND ONLY BRAINS can generate consciousness. If Lacrymaria interests you, check out the work of Michael Levin of Tufts University. His 2018 NeurIPS talk, (on youtube), "What Bodies Think About; Bioelectric Computation Outside the Nervous System," is fascinating.
It's not dogmatic at all, it's just ignorant and dumb people tend to assume that they are one of a kind special and by extension that everything else is inferior. Of course you don't need brain cells, you only need any kind of mechanism whatsoever that operates by some defined set of rules - with the right set of rules it will produce intelligence.
I appreciate the comments Mi and Osmosis. I will admit though, that I had a much different train of thought in mind than what your responses hint at. Mi, I want to point out that I make a big distinction between consciousness and intelligence. Also, I'm not quite sure what you are alluding to with, "you only need any kind of mechanism whatsoever that operates by some defined set of rules," maybe you can unpack that statement a bit. Osmosis, I agree with you absolutely, the brain is not a computer, even if we might be able to make some strong comparisons to the functioning of computers, and the the functioning of neural systems. It is an interesting idea to think of individual neurons as computers themselves, (you may want to check what Dan Dennett has to say on this, it reminds me of some of his arguments.) However, I don't think the brain is a computer, and I don't think neurons or any biological cells are computers either. From my positions, life and biology, are in a different category from human imagined and designed systems. I don't believe that humans can inject the "right stuff" into any system which will render it truly alive or conscious. Well, ignoring the obvious example of human reproduction itself. I'd appreciate hearing both of your responses if you're willing to take the time to respond.
@@S.G.Wallner Human intelligence and consciousness comes from billions of neurons operating by simple rules, and it's the specific rules and specific arrangement what makes it produce intelligence - not the number and especially not them being neurons specifically. Anything that exactly replicates neurons can exactly replicate human brain, it could be something as simple as molecular engine operating on individual compounds, or it could be analog or digital logic circuit. Moreover, it doesn't need to replicate human neurons specifically, it could be any abstract set of rules (e.g. Convay's Game of Life produces pretty interesting effects out of just 2 basic rules) it just needs to happen to be the right kind of rules to produce intelligence. Us humans have this exact set of rules embedded in DNA because every specimen that didn't, died off - only the good samples made it to this day, i.e. the evolution specifically selected for these rules out of trillions of random possible combinations, and as you can see in the video the same happened in a single-celled organism, to the extent that it was useful and/or feasible to accomplish. If you put artificial neural networks in a simulation with selective pressure for intelligent behaviors, they eventually become intelligent. Now, to go from scratch to human intelligence will require billions of years worth of simulation and simulating billions of neurons isn't exactly speedy operation, so nobody's doing that kind of sand sifting to find the kind of artificial rules that can create artificial intelligence - but we might eventually, just for kicks. It's currently pretty obvious that just a big enough natural language model can effectively be an artificial intelligence with human-like capabilities, we don't actually need to have the real deal because we've figured out how to make fake work just as good.
This goes a long way to illustrate the universal "Principle of Correspondence" which means that what happens on a large scale happens on a small scale and vice versa. Just like animals have to feed, rest, multiply and they have special organs for each of these, so do these small single-cell "organisms", just at a smaller scale.
you're doing great work.
"Intelligent design" is a lucrative myth, but that extensible protoplasm idea verges on ingenious.
The universe and planets and life is literally in perfect order to function. How can you say intelligent design is a myth? Ignorant.
@Georgies51 Only those utterly ignorant of science and medicine can believe in "perfect" order. Go away, ninny.
@@tammcd What an anti intellectual way of dismissing a point you don't like 🤣 You don't know anything about science or Medicine so stop trying to sound so smart. Science and medicine doesn't disprove intelligent design, it does the opposite actually.
The r/atheism user woke up groggy next to his 6 pack of empty Mountain Dew cans. He lifted his 400 pound frame off his bed wondering how many women he’d be able to harass on Xbox Live today when just then he remembered: today was the day. Today was the day he would finally get a chance to debate Christian sheep and slay their god in heaven. Excitedly, he got on his disability scooter and then into his 2007 Toyota Corolla. He drove to the hospital, scoffing every time he saw a crucifix bumper sticker and made sure to situate his fedora before he got out, parking in between two disability slots. When he entered, he got his camera ready, and going up to the third floor he thought “Reddit, the last enlightened place on Earth, will finally give me the attention I deserve and recognize me for my intelligence.” He entered into the room where his grandmother was lying and drawing her last breaths. A priest was standing next to her along with her children and grandchildren, anointing her and hearing her last confessions. “This is it,” he thought, “this is where I own those religiotards and achieve victory for atheism.” He boldly walked right next to his grandmother’s side and just as the priest said “may God bless your soul,” he bravely rebutted with “but there is no god to meet you in heaven. None of it is real. Your sky daddy won’t save you this time.” His grandmother looked on him in shock, opening her mouth. But then she slouched and a long beep was heard and her mouth remained wide open. “Yet another victory for atheism,” he said, looking at his family members who were stricken with faces of horror. “I’m sure they’ve finally realized their God is dead.” He opened Reddit, excited by the prospect of the karma he was going to get by posting the video he took on r/atheism.
@@ausore9832 Brilliant 🤣🤣🤣🤣
There’s something about the way these ones move that I find really unsettling. It’d be an excellent monster in a movie, crashing around a city and thrashing about its horrible neck thing.
Wow I love these journeys!
Would you like to do a video about phytoplankton? I am currently breeding Nannochloropsis salina for my marine aquarium. Isochrysis, Chlorella,Zooxanthellae or Noctiluca scintillans would be very interesting to see
Another amazing creature beautifully portrayed. I’m not from the US but I find it great that you are referring to videos that explain people how to vote. In many countries voting isn’t mandatory and so there is the chance that many citizens don’t have the chance or the information to make their voices heard. Participating in the vote is taking active part in the government of your country. Don’t forget a lot of good men and women have given their life in the past so each of us can now make our voice heard. Vote, it’s your right.
Excellent work James👍
It's an interesting strategy. For a single celled organism. If it takes too much energy to be fast. Make part of yourself fast, and connect it to yourself with a tube. So that it doesn't get lost, and it can pass food to you.
Wow, Andrew Huang upped his game for this one.
I love this channel... thank you
This is so sick! It's incredible how everything is moving down there, a total rush of life!
Hank I hope you appreciate that you made science ASMR
@5:24 I know the lacrymaria is the star of this show but what are those little little (compared to the lacrymaria their little) worm like things in the bottom left corner, they move a little bit.
So I'm just curious what are those?
This is an amazing channel ❤️
