Someone cut off the first video about hydra, so two videos grew back in its place!
XD, Nice one.
Hail Hydra!
Those shots are so _detailed_, it's like I'm actually physically there, floating above the sample. It's awesome!
If you want italics to work with punctuation, you have to add the punctuation inside the underscores, like _this,_ not _this_.
I just got a 4k monitor last week and man I couldn't agree more. This whole channel is gorgeous
The Micro' in HD and bigger than ever, but so transparent we can see right through them !!?!?
yeah, this channel has the best microscope content I've seen TH-cam
@@johnjordan3552 I didn't know there were any others :)
Last time I was this early, we were still calling them animalcules
Lmao
Last time I was this early phlogiston powered my lighting system.
Those Kerona things are so adorable, my goodness.
and they are probably on your face
I made a balloon of this thing for an art class, was pretty fun.
*Hydra exist, devouring everything on it's path
Kerona pediculus : YAY A PLAYGROUND!!
Fantastic job, Deboki! Also to James- our boy is so excited about your 100x objective. He was practically drooling along side me watching those star-studded details!
Awwwwwww!
These videos get more detailed and fascinating!
I love the repeated "We don't know". This show does an EXCELLENT job of demonstrating the limits of our collective knowledge, but without dumbing things down or venturing into misleading clickbaity terrain. Amazing!
The Kerona and the Hydra is like a tiny version of the Clownfish and the Sea Anemone. A microcosm, if you will...
I thought the same. Can’t wait till we know the answer
Hydra, anemones, coral and jellies belong to the same phylum.
Only difference is that clown fish are known to be immune to those toxins.
@@johnanders8760 looks like the Kerina are as well. Perhaps they are not being "stung".. don't know didn't like the narrator
@@patldennis She said that they aren't.
Absolutely insane visuals in this one. This channel has always been visually great but this is on another level of beauty and detail. Just gobsmacked lol
Imagine the beauty and awe you would witness if you watched these vids while tripping nuts
HAIL HYDRA!!!
HYDRA DOMINATUS!
I'm happy you're back, Denoki!
Thanks for all of your writing, and your recent foray into hosting.
Youre getting more comfortable with the narration. 👍
"Not like the beer or the virus"
Even though corona is latin for crown and was adopted into the rest of the latin-based romance languages with the same meaning....
@Journey to the Microcosmos Hey, did you guys ever end up getting samples deep down from a drilling company? The reason I ask is I actually know a person that tests those samples from all depths for a Texas drilling company. During the process, he actually throws out the excess from the sample that isn't needed. If you still want specimens, I can ask him. He would also be able to label the specimens with what types of dirt/minerals are included, as that's what he does for his job.
I would be really interested in this
@@starlessstephtx I remember watching an episode on this channel where Hank said they were trying to get in touch with some drilling companies for deep down samples. The person I know actually labels samples with the depth they were collected and the mineral contents. It could be very interesting, indeed.
Geology and the Oil industry is such an awesome thing to learn about simply because of what can come from it! I wish I had thought of this!
They would only contain bacteria invisible to a microscope IMO
3:12 Mac wants the Flamethrower.
_Steve Rogers has left the chat_
Thank you for the video. The upgrade you guys did is the best thing that has happened to TH-cam in a long while.
Hail Hydra!
I had an infestation of hydra in an aquarium once. Getting overzealous with feeding live baby brine shrimp to fish is a top cause. But hydra are visible to the naked eye and positively fascinating! With a small (4x) magnifying glass, you can examine them more closely. They do no real harm to aquarium fish. Some say neocaridina shrimp are at risk, but my population of shrimp thrived.
7:44 "they'll kill the hydra and steal those nematocysts for themselves"...wow that's brutal.
What an awesome channel.i loved biology in school.i love it more watching it in such amazing details,in the comfort of my living room.ty so much...
Back in elementary school we had to hold a presentation on our favorite pet and I held one on hydras. Lol
Lol
everything is so bubbly.
Corona means Crown
Ty for the vid!
Interesting... reminds me a lot of animal relationships in marine/reef life.
Amazing video!
I wonder what Tremblay would have thought of carnivorous plants that can move...
I just got my Hydra T-shirt! Thankyou Microcosmos, and for those Shield fans, "Hail Hydra!" :)
That flatworm is out there playing monster hunter
Love love lov
love when Deboki guides us through the microcosmos! Of course I love hank, I've been a nerdfighter since that was a thing, but I love hearing her passion and she makes everything seem so interesting!
Absolutely excellent!! I LOVEEE this channel so much!!
Very beautiful
So cool.
I don't know exactly how Kerona managed to slip and slide all over the hydras tentacles. But it does make me think of something else with a similar behaviour. Clown fish living amongst sea anemone. Clown fish rub themselves up against the tentacles of the anemones to steal their mucus. The mucus stops the anemone from stinging itself. And voilà instant bodyguard. I noticed how Kerona slips and slides up and down those tentacles of the hydra. Perhaps it's doing something similar.
Another great video by journey to the microcosm. Thank you.
Amazing! Thank you! Not only great footage, but great production overall, I especially love the soundtrack.
My fav channel ❤️
3:59
What? Trembley saw a hydra capture a millipede? !!!! The insect, millipede ? !!
Another fantastic video, thank you all who worked on it
Can we get a photo or poster of the Galaxy hydra at 4:54? It looks like a little galaxy in there!
This is cool .
Beautiful footage as always, I feel transported to another scale of being.
One of the coolest things I EVER saw was a video of a hydra (Hail Hydra) that got grounded up into must, literally... Then, over the course of a few days, the cells of hydra reorganized themselves back into a living, functioning, full hydra. You think of life as being so fragile, however, this animal was ground down into paste, but was able to put itself back together, literally, and go on living a normal life, as if nothing happened. Truly incredible. No wonder scientists are so obsessed with stem-cells.
Mindblown on how detailed these video is!
I don't mind people other than Hank voicing the videos... but you gotta read the script like you would a bedtime story to a child whose sibling is already asleep in the bunk-bed overhead.
Slow down, lean back, chill out - those micro-creatures aren't going anywhere.
Literally my exact thought
Beautifully done
Surreal
I really hate to say this but I can only ever enjoy these videos with Hanks voice....
Important
Wow...the crisp and clear, beautiful images...im continuously amazed by how good this channel is =D
Wow
Themselves can regenerate there entire body
Wonderful work
Hey that’s me!
Amazing! Thank you :) Looking forward to finding some Hydra with my own scope eventually.
Dude this s is just really cool
Complexly amazing
Wow that was amazing
The Kerona appear to be grooming the Hydra in a symbiotic relation .
Stunning photomicrography!
Thanks Deboki for this awesome script and narration!
This new video on Hydras is so detailed! Congratulations James! And Deboki narrated it very well 😊
thanks for the amazing hydra footage (and for telling me more fun trembley facts!)
Enjoyed your video and I gave it a Thumbs Up
It keeps the kerona around for a rainy day snack
Give me hank back please.. where is hank? My boy..
Hi new narrator, good job, very easy on the ear and clearly spoken thanks :)
If I may... She is actually the writer for this channel and occasionally the narrator.
Check out other two videos where she did the narration: "How diatoms build their beautiful shells" and "The diversity of shapes in microcosmos". 😊
@@mimiteas oh okay thanks for the info.
You know what would be a cool a video on the pond tank and it's inhabitants
I’m in college biology and I hate it but I love your channel weird
These videos are amazing! It's like going to another planet and looking at alien life.
Music by Andrew Huang nice!
There are also sea slugs that eat sea anenome tentacles and incorporate some of the un-activated nematocysts into their own body’s defences.
Kerona pediculus crawling on hydra fingers: "Yubi yubi!"
ah i see, you''re a man of culture as well
this is so beautiful
New hydra hype
Cut of one head two more shall take it’s….wait wrong one, but also not wrong
Amazing
Deboki... You have such a provocative voice! I mean that in the best way. You make me want to listen - and learn! Please do more of these.
This channel is incredible.
I remember learning about these little guys in high school.
The famous hydralisk
So awesome 😍
Anyone else mentally repeating the narration in their head but with Hank's voice? No offence meant to the lovely voice of the new host... but, having been listening to Hank's soothing tones since the start, I kind miss how calming and comforting he is.
this channel is amazing
Hydras or very similar Cnidarians have been around for 650 million years, surviving ALL the major extinction events.........doing something right, I guess.
You didnt say anything about their ability to reform themselves after being blended like a sauce. Yes its Imortal.
That's crazy that it was left out.
They talked about it on a video about hydras two years ago :D
I can't believe how incredibly beautiful this microscopic world is! Thank you so much for bringing it to life for the public!
It's hank who's speaking
_very_ nice!
Great photography here!
Who's the new narrator? The credits still show Hank.
The writer, Deboki Chakravarti, who has done one or two previously as well, lightening Hank's load, but seems to be doing fewer than he does.
5:39 That sounds like an insult she could use when considering who to date.
When will the guy be back?
What if the Beauty were the Beast?
I really enjoyed Finding Nemo, Microcosmos Edition!
I didn't realize that hydra were related to jellyfish, that is interesting. Very interesting that hydra differentiate between prey and predator so well. For something so small, it is easy to think that means they are not intelligent, but that is just my cognitive bias based on being in the macroworld.
where the other narrator. please bring him back. please
I Love the new Improve detail to the Image! from the info, I’ve gather your colleagues so happen to stumble upon this more detailed technique using oil? (Fascinating)
We will appreciate an update regarding the microscope
I took fresh water from the lake and caught some kind of polyp. It doesn't look like a hydra at all. It looks like some kind of round bush, if you shake the water, it curls up into a ball. It preys on copepods. I've been trying all day to find what it is but I can't. On the Internet it is written only about the hydra. Can you suggest something?
where is hank?
Man i love seeing the monster plaguing my aquarium
