This is kentrophoros, a ciliate that James-our master of microscopes-had been searching for, receiving samples from all over the world in the hopes of finding it gliding around. When you first look at it, it doesn’t seem particularly special. But there are two things that the kentrophoros is famous for. The first is its lack of a mouth. The second is its coat of bacteria.

[@Periwinkleaccount]

You know, the phrase “carbon footprint” was created by an oil company, apparently. Also, it’s mainly companies that make the carbon emissions, and also force people to use products that also produce carbon dioxide. We should be more concerned.

CORRECTION: At 7:00 we misspelled Tom Fenchel's name.

[@AccidentalNinja]

It makes sense to me; it's like domestication. Some of you might get eaten, but you're also enlisting the help of another species to take care of you. So long as it still exists, so will you.

[@Pufflizard]

Some of you may die, but that is a sacrifice I'm willing to make - Kentrophoros

[@alienworm1999]

domestication wasn't really optional for the species we domesticated, though

[@keithyinger3326]

Especially if I was a bacteria that was genetically and pretty much identical to every one of my kin. Go ahead and eat the couple hundred of me. There's still thousands out there. We're all the exact same anyways. It's hard to think about that concept as a human being where each person is their own unique and individual personality. We are all basically the same, but we're all very different from each other.

@@alienworm1999 nor they benefited too much from us

[@randompheidoleminor3011]

@@alienworm1999 our livestock consists of 65% of all mammal biomass on Earth, humans 32, amd the remaining 3 are wild mammals - from the smallest mouse to the largest whale. Many of our farm animals may live miserable unethical lives on the roughly 38% of all habitable land on Earth set aside for them, but from an ecological perspective they have absolutely come to dominate.

[@osmia]

Changed my mind from the last episode. This time I choose to be the gardener!

[@Banzybanz]

Like small vendors supplying to a large business that is interested in vertical expansion.

[@stax6092]

Cool.

[@adrianpintea9675]

Perhaps there is a priority in the consumption, like culling the sick, old.

[@trapsquad593]

The mitochondria is the powerhouse of a cell

[@johnnesbit2371]

Considering that we ourselves are--and normally!--very considerable biomes with perhaps dozens, or more, of different micros enjoying their lives in our innards, we should not look on the Kentrophores as anything bizarre. Except perhaps for the fact that they like to "dress themselves" with the bacterias.

[@jendragon42]

Anybody else getting trypophobic heebie jeebies from the bacteria clusters? {shudders}

[@amberwalsh5767]

Enjoy listening to you Hank but you don't seem as excited about this as Scishow

[@bigbrady2244]

Oh no, bringing up the nonsense of evolution again. How sad to hear that stuff included with science.

[@JamsGerms]

I cannot express how much I love Kentrophoros! They are fascinating but so delicate which makes them quite hard to record! -James

[@luisaparodi8571]

Congratulations for finding and masterfully recorded this tini microbe bus!!

[@TheRogueWolf]

The one at 7:03 looks like it wasn't having a good day, if that seeming trail of cytoplasm is any indication.

[@exploremicroscopy]

You've done a magnificent job of recording them though. You're microscopy is superb!

[@st1220]

hai james ourmasterofmicroscopes

[@jrivera2240]

You should make a series on wastewater organisms. Work at a wastewater treatment plant and it would be great to have one made on them!

[@sudalie7914]

this channel is so comforting. idk why watching microorganisms is so relaxing for me

[@joppy232]

Me too! I love watching right before bed

[@selfworm]

His voice is super relaxing

[@DekkarJr]

same dude - its very calming lol XD

[@soranuareane]

One of my favorite words in biology: phagocytosis. The microbe equivalent of "om nom nom".

[@alexio1942]

to the bacteria the celliate is its whole world like the earth is to ours, some of us thrive, some of us die and become consumed by the earth. theres really not much difference when you break it down

[@fernbedek6302]

Humans have settled on volcanoes all the time, due to fertile land. Even if it sometimes opens up and spews forth destruction. Seems similar enough.

[@UniDocs_Mahapushpa_Cyavana]

Truth. ✅

[@StrikeWyvern]

This makes me think about how Mitochondria formed. Anyone think a relationship like this could be a precursor to becoming an organelle?

[@dweebteambuilderjones7627]

The closest relatives of mitochondria are intracellular parasites, so they would've evolved from parasitic bacteria that an archaeon swallowed but failed to release so they could damage it.

[@gvasilyev84]

I don't think multicellular organisms can create new organelles. Bacteria should infiltrate reproductive cells, which in any multicellular organism do not need to worry about food

[@JoseValencia-fr8wh]

8:17 that image is so clear 😮

[@el_spaghetto]

This is by far the earliest I've ever been to a video about this particular subject.

[@NewMessage]

Well, we've all thought about eating our roommates now and then. What?

[@ethanbanks198]

It would be so cool to see fungi spores and mycelium!!

[@tyshalley6130]

Love how you're moderating your voice for this. With maybe a touch of cadence from Carl Sagan, or perhaps Jacques Cousteau. With that and the excellent audioscape it does feel very much like a journey. Keep up the great work team!

[@JoseValencia-fr8wh]

This channel is my escape from nuclear bs

[@benroberts3677]

I FORGOT IT WAS MONDAY!!! THANK YOU ALL SO MUCH

[@saucevc8353]

Hello! Do you know any good places to find microbe samples, say, in the backyard? I have a microscope but haven't seen very many exciting microbes sadly and really want to see these awesome creatures for myself!

[@marilynwasserman3273]

Well, long ago as a Freshman college student we learned to make "hay injusions". Fancy name for pulling up a bit of grass and letting it sit in water at room temp overnight. Doubt you'll find anything exotic but it is a fascinating little world. Paramecia, amoebae and others you've seen on this channel.

[@smooth_sundaes5172]

Yey! More Microcos'.

[@UniDocs_Mahapushpa_Cyavana]

If the bacteria 🦠 is single soul, they would extremely chill about being eaten, like humans 👥👥👥👥 a chill about their dead skin cells falling off.

[@Yezpahr]

So it has come to this... Time to send this to all the Kent's we know, people. Hurry and scurry!

[@EldiumCraftwerks]

Rather than gardening, it made me think of raising chickens. Farmer provides feed, chickens produce eggs, and ever so often there are chicken noodles on the menu.

[@williamchamberlain2263]

Acne that you can eat

[@gabrielrivera8131]

These videos are so interesting! Super high quality! When I want to watch the video I always learn something. But when I don't do that, I also tend to use it as background noise and fall asleep to it. Like reading a book before bed!

[@smooth_sundaes5172]

If we could ramp up the sound of the microbe world I think we'd all be deafened

[@Dth091]

Mmm, Phagocytoast..

[@Beryllahawk]

Phagocy-TOAST I see what you did there Fascinating creature, and situation! Another wonderful video, thank you!!!

[@MovielikeCinema]

Wow! Audio track in other languages!

[@ray1956]

It’s like Humans fatty storage 🤷🏿🧑🏿‍💻👨🏿‍⚕️👨🏿‍⚕️

[@Dr.Reason]

OK wait, I just have to ask, regarding your Wren add, how does paying some random guy offset your carbon emissions? Doesn’t it really just ease your silly feelings of guilt rather than actually have an effect on the universe? And if wren gives you the calculated as well as takes your money calculated, I’m smelling a financial scam. I’m just asking.

[@redofthewolves]

Love the little nod to the angler fish near the end

[@madisonrolig855]

I’ve taken to watching y’all’s videos at any chance I get. Even to sleep. So soothing! So educational! So beautiful!

[@scottsmith4204]

Everything dies eventually so that just makes both choices wrong.

[@benjistokman]

Ah yes, I love calculating "my" carbon emissions when I'm not given a choice to emit...

[@REgamesplayer]

Author, do not get jealous of bacteria's way of life. You are human, not a bacteria!

[@desperatelyseekingrealnews]

Shame on you for promoting the carbon scam unsubbed😅

[@melodyszadkowski5256]

The benefits to an individual and benefits to a species often differ.

[@McStealy]

Organisms living on a surface that can shift and consume us sure sounds like the human experience.

[@dante7228]

Perhaps the bacteria get eaten because they are at the end of their life cycle and it makes sense to feed the host that still builds the home of theirs offsprings...

[@danielscottjzx100]

Great video, I enjoy your voice it almost reminds me of the gman from the half life games

[@orgeuillealkali]

It’s Snack Braff in micro-monster factory

[@fuckgoogle9581]

i wouuld gldly sent samples from the uk

[@freehat2722]

Was perfect until you sold out in the end with carbon bs.

[@KendrixTermina]

I guess it pays for the bacteria so long as they're not all eaten at once

[@Ratciclefan]

Oh wow

[@deathsnitemaresinfullust2269]

Haa! Really neat how some of this footage looks like it could be mistaken for deep sea ROV footage or something like that when in reality some people can't even comprehend just how small this is. 😄👍

[@dembro27]

Eh, we're in a more similar boat than we might think. We're all hitching a ride on the giant vehicle known as Earth, and though it isn't a living organism, it can still open up and swallow us whole.

[@See_Jay_Play]

PhagocyTOAST, amirite?!

[@anahigajardo7200]

is it bodsible for you to talk about the B12 generating bacteries that are so important for us?
