From our vantage point, as relatively large organisms, it can be easy to overlook the microcosmos, because it’s simply too small to see. It floats in front of our eyes at all times, and yet we cannot make out details until we turn to other tools.

Anyone else find it really cute when the halteria at 3:30 balls up and then just sticks out a couple of cilia before unfurling like it’s testing the waters?
You do foo? 😮
*too 😣
Watching them spin is so cute
They spin right round, baby, right round
The hamster dance plays in my head watching them spin
Really do love these videos. They always help me wind down and sleep at the end of the day, or help me to start my day on a better note:) before this channel, the microcosmos was just... Algae and daphnia fish food:,) now I'm aware of what's actually living out of sight and what they look like and do! Its always so fun to learn about these little friends. Thank you
Hopefully thought-provoking:
Some More News and Second Thought are 2 TH-camrs famous for being Voices for the Worker-Class. Their videos about Work, Unions, and Capitalism, are amazing.
This is my 2nd video of this sort. Immediately my eyes and skin started itching and I think my asthma is kicking in.
I really think you should create a discord server.I really have a hard time identifying a species,but a large group of people can really make things easier!
They have one, but it's for Patrons only
_Halteria:_ The nervous cats of the microcosmos.
Wait are you guys able to do a video on fish fry and microorganisms??? Learning about how the baby fish digest their food when they're so much smaller than a grain of rice would be amazing!
I love to hear that voice!
Love your team!
... even if he is obviously in "recovery mode" after a cold or flu.
6:55 actinobolina seems like it's perfect for being there to get run into to catch prey
I've always wondered how exactly cilia (and flagella) work without muscles. I've looked into it before and there seems to be a lot of complicated biology going on with motorized proteins and weirdness like that. But unfortunately it was a bit over my head as it was from the source I consulted. Maybe I could find an easier source to understand if I try again. This video also got me wondering how a single celled organism can detect when something's touching it, and whether that something is dangerous or not so it can retract. These are complex behaviors we tend to associate with complex structures like nerves and ganglia. Not a single cell.
Yes! Like the ones with poisons get bumped into by other things all the time....but only certain ones being hunted trigger the sting/paralysis.....how does it "know"?
Some slow motion would have been VERY helpful in this instance.
@@samarnadra Everything you say is true but at least some slow motion would have been helpful. Prince Rupert's drop level slow motion is outrageously high frame rate. I'm sure they could slow it down about a hundred times. We might have seen some of the flagella moving or however they propel themselves. A jet maybe? Should have been possible with that level of light or close.
But, as you say, we get better and better at it over time and it gets cheaper and cheaper for average folks. Something to look forward to.
I have to remind myself that these things actually live in a three-dimensional world rather than the two-D world of the slide! When they dart around, they can be darting up and down as well as sideways.
I wonder, has anyone made high-speed (slow motion) movies of those Halteria moving around?
So happy to finally see Halteria on this channel!
Trying to find out what microbe you're looking at by google search can be a real challenge. Despite Halteria being one of the most common microorganisms to come by in the hobby, it still took me more than an hour of searching before figuring out what it was. There are so many sun-like, round things with pointy bits and no good holistic database to search through.
Wow! I thought I was the only one interested in cyclidium and their amazing speed! Almost no one notices and it’s hard to find info on them.
This channel is so delightful! It's inspired me to buy my own microscope. It's just a simple one, not much better than a toy, but it's a start. Thank you all for everything you do!
Hank you really put on a different persona and voice when you're narrating these videos! I hadn't realised up until now it was you - you've really captured a different style here!
Back after a few years, seeing this vid was posted 1 day ago made my night. 🤗
I follow you from Italy, I'm an environmental biologist, passionate about botany and microscopy and i'm in love with this channel! The scientific information is correct, the images magnificent and the narration engaging. Good job guys!
Amazing channel, every video is great.
I really love this videos, they help me relax and at the same time I learn. Thakn you James, Hank , Deboki and the other guy.
I was microscoping water the other day and I couldn't figure out, what two microorganisms were and thanks to this video I know now!!! It was halteria and vorticella! Thank you so much for making videos like these!
SciShow Space should title the JWST info, "journey into the Macrocosmos"...
edit: ohman, Strombidium video, when?
Video dubbing is excelent! Thank you!
Always informative, interesting.......and relaxing to watch. Thanx !!!
Thats odd cool though.
Can you do some extreme cells please like brine high ph or low ph water life .
I love to watch these videos before bed. You've created one of the few very relaxing educational shows. But I've noticed the narration and music to be speeding up a bit lately. Would you please think about slowing it back down? 🙏
I thought it was just me!
Going to the beach to collect samples soon, hopefully you will release another marine video soon
thank you
x
Everytime I see these videos it ways makes me jump up to go figure out why they do the things they do! Maybe I can finally figure out some of these mysteries! I have almost saved enough 💰to get a "good" microscope! Thanks so much for the video and helping to keep my curiosity alive ❤️
You only want to figure out how they get you high!!!
Do they produce cavitation ?
I really doubt it since they are squishy, but this is an awesome question! This might be a good use for the slow mo everyone is mentioning. It would be neat to see how their shape conforms to the pressure gradient they cause with their rapid movement and see how much faster they would need to go before a cavitation could occur.
Imma need a tiktok with videos of halteria with the helicopter helicopter sound
Cool! Love this new video! Really interesting stuff 🥰🙌
The Halteria is like me driving 90 mph trying to do my hr and a half commute, and zooming about on my workday, and then wanting to pretty much do nothing when I'm off.
Thank you for this lesson! I witnessed one of these in a microscope while looking at some aquarium water many years ago. Neither I or the lab instructor could workout the exact identity. At high magnification, it was moving so fast to different locations that I kept questioning my own sight. I understood how tremendous of a feat it was for something to move such a relatively large distance in such a short amount of time, and kept thinking, “is this thing warping space time around it, and sort of teleporting?” Of course, the microscope that this channel uses is tremendously more powerful and resolute, and so now, I can see the ciliate’s full movement. Either way, this episode is awesome!
Well information. Good show. Well information.
Great video! It can't be easy to keep track of these zippy little dudes!!
Could you make a video about giant Bursaria ? Stentor is longer than Bursaria but Bursaria is larger. I think the Bursaria actually appear in this channel too in the Jul 30, 2019 tardigrade video at 10.15 as it try to eat the tardigrade.
I had forgotten how fascinateing ciliates were since studying them in A.P. Biology many years ago. Thanks for reminding me!!
Oh wow... This is dope!
All right, somebody notify the slo-mo guys about their new challenge.
Fantastic
Hank just might be my favorite orator
Enjoyed your video and I gave it a Thumbs Up
3:00 Halteria go Weeeee
Awesome!
I wonder how these super fast images would look with a high framerate camera. Say, show it down to micro seconds and such.
Rotifer would have loved this snack commercial.
Man.. they don't even need a morning coffee to do that. Pops, G.
600 feet per second is a bit over 400 mph. think of the G's.
How did you culture them? If you put the videos on how to collect and culture them it will be amazing😉
Must take up a lot of energy
This bacteria effortlessly travel at the speed of sound without any apparent means of doing so. Imagine if we could build such means of transportation underwater.
Cool.
What's a decent telescope to start off with?
i dont understand why not more people watch this
increíble video, muchas gracias!!!! pero usen el sistema métrico no sean herejes....
3:35
Awsome
Wow, cool views
How do you guys get so much detail on fly legs and such? When I want to look at an object I have to hold a flashlight up above the slide instead of the microscopes light so it reflects into my lens or else it’s just a black silhouette of the object
I think the microscope he uses has a ring light with a difuser around the lens.
how often do they hit something though? maybe the actinobolena is getting too much credit and just evolved to eat the squishy dots that keep teleporting onto its spikes
With my old old eyes I miss a lot of things. My wife claims I can still spot a fly honey from miles away. But I assume that is just an excuse for her to get mad. Rightfully so...that honey was indeed a fly one.
Cyclidium appears to have a circular structure at one end that looks like a tiny heartbeat. What is that?
Contractile vacuole, used to pump water out of the cell.
I always wonder if these little guys can think or feel 🤔
Science may so nah but in the grand scheme of it we are as minute as them
I guess if they can sense danger they must have some form of intellect
They move like UFO's do.
New mic ? new host? have I lost my mind?
Can I use your song please I’m gonna make microscopic vid too
👋
Hm I thought this channel would get more views. That Fredrick guy gets heaps
So, Halteria is like Elon's satellite constellation.
Imagine if scientists figured out what makes Halteria move so fast. Through biomimicry we could make our boats and spaceships move faster to. Or a diving suit. You'd zip through the water like Aquaman. Come to think of it they kinda remind me of little UFOs you seen the videos a ball of light seems to just zip off out of sight.
we need a collab. with slowmoguys
What is the beautiful creature at 4:15 ?
If you look very closely, it tried to bite our main character!
A rotifer.
@@samarnadra I think you might be right.
Looks like Daphnia or some other "water flea". You should check out this channel's video about them
@@samarnadra There are two Daphnia. The first is partially trapped in that bubble at 4:15. I think that's the one TheSphongleface is referring to. When the first daphnia moves one of its antenna at 4:17, the little guy runs smack dab into the second daphnia centerished at 4:19
That jump shouldn’t be possible! Wtf?
WHAT!? How could you have such a short vid on such an interesting topic!? How tf does it move so fast? You cant follow that up with, 'we just dont know'!!!!
Wait you use nano meter an such and then say feet, that’s weird.
FIFTH
first
I was devastated to learn that Hank doesn't like pineapple on pizza. Unsubscribing
So disappointing to see the pseudoscience of evolution added to your work. You do some really good stuff without the nonsense.
Evolution isn't pseudoscience.
... bruh this is a science channel. Not a religion fantasy channel. Evolution is science. What do you think is happening here?
Proven things aren't "pseudo-", that prefix means the opposite. Not only is proof of evolution well documented, but researchers have even observed it happening in surprisingly short order. Suggesting reality isn't real, or hiding from it, does oneself a disservice unfortunately and inhibits interacting and growing and participating in the world effectively.
