CORRECTION: The clip that starts at 1:15 of a green hydra riding a snail is actually 40x, not 400x

[@primus4cameron]

But where is a handy scale bar that's screen size independent... please please please

[@aparadoxicalone]

I'll second the request for a screen-size-independent scale bar, since otherwise I'm forced to conclude all the organisms in your lab get ~5x bigger when I move from watching the video on my phone to on my pc.

[@jonathanlehmann2059]

Yes. Thirded. If future videos had both a scale bar and a magnification number, then the viewer could also imagine the scale bar in past videos with the same magnifications.

[@redmadhatter03]

Wound-mouth is probably the worst way to describe it

[@animorph17]

Back in my day there was this huge spiraling debacle about answering "what is the driest climate" on a biology test. The answer the school demanded to keep in accordance with texas regulations was a desert. The answer I gave, the correct one with (then recent) sources to back me up on it, was Taundra. Imagine a 7 year old bringing college level biology books to school so he can argue with the principle. I love the fact this merry tradition of old teachers getting blown away by new developments is still maintained. As research continues ever onward and information is far more widely available. In the age of information, ignorance is a choice.

[@djinnisequoia]

The cells being ripped apart into a blend of separate cells and then reforming into a hydra is 😱🤯!!

[@psychicrenegade]

They have some amazing DNA!

[@IceclawFirebolt]

Ripped apart is a bit harsh, we actually dissolve the cell-cell contacts and then gently tap the tissue apart, so the cells don't get damaged :) But yes, we can even combine several different polyps this way, who will then form chimeric hydra. And as they regrow, they often form several heads and stalks, so they may temporarily be "real" hydra. After a while they will fall apart into different polyps though.

Have they tried blending cells of two hydras to see if they fuse or if they reform separately?

How would you tell which cells came from which hydra? Maybe use two different species?

[@ottoia9126]

@@TheFinktron oh, simple: two hydras go in and if one comes out, they do indeed fuse and we just created a stronger double hydra

[@TheMnimatt]

woah!

[@ValekHalfHeart]

​@@TheFinktron There are several ways you could tell. For example, you could genetically engineer one hydra to express green florescent protein (GFP) and see if any of the cells in the reformed hydra glow. Or give one of them food containing radioisotopes that would then be anabolized into its cells, making them radio-labeled. If a chimera was successfully produced, you'd expect to see some labeled cells, but a lower proportion than in the un-blended labeled hydra.

Who needs other forms of ASMR when you can just listen to Hank gently describing microscopic creatures

[@opposumness3107]

Can't stand ASMR or the hurried and snappy nature of Hanks previous narrations. I, However, think that these narrations with these musical arrangements, is pure, auditive nectar of the gods ❤️

[@blueisnotgreen7258]

I think they’re terrible. And I love the content so much I just can’t watch this without it being on mute. Especially when they have the water sound effects added arbitrarily to the footage. I’m not a negative person by nature but I have misophonia so the sound is painful. Even if it wasn’t its arbitrary and while I think it cosmetically seems to “belong” with the imagery It’s just way too much. I love learning about this stuff But I could play instrumental trap music along with the narration myself If I wanted. It would be much better By itself. In the Microcosmos, sound Has a very interesting role. Things don’t hear other things nearby. All sounds indicate giant environmental changes. And they are Interpreted as physical vibrations. Artistically maybe this is Pretty but if you don’t like that kind of music you’re screwed. Its a documentary And it doesn’t really belong. Then Again ASMR makes me want to tear my head off of my shoulders. My condition basically makes it so sound Feels like it’s touching my bones. I don’t know how else to describe it.

Besides my general interest in, well, everything in nature, I think that examination of the microcosm is extremely important even to help us along our journey of understanding life and the universe. Specifically with respect to the hydra and immortality, the discussion naturally begs the question of "what is life" and "does life as we define it need to be carbon based" and other similar questions. Also, in my biologically-layman's perspective, I think the microcosm arena is the best one to instigate discussion of "the why" nature works. Humans tend to anthropomorphize everything, ask questions such as "how does it know to flap its celia?" etc.... These video make me think more deeply about such questions....

Reminded me of the comic book hero Wolverine, whose hand rips apart and heals every time he extends and retracts his claws.

WOW...the video images are astounding!

[@anosmianAcrimony]

So what are the woodlouse-lookin' things crawling on them?

[@zddxddyddw]

Ciliates.

[@AssistantCoreAQI]

Hypotrich Cilliates.

[@danielnewhouse7033]

I wondered about that too

[@isahellepain5002]

Do a video about nematodes or some other kind of worm?

[@a.b.8606]

That was AWSOME!

Great vid! As a tropical fish breeder who feeds lots of baby brine shrimp to my fish fry, hydra explosions are a regular occurrence. Fortunately I’m also a biology teacher. Kids love hydra!when I’m done showing them off, a little dog dewormer takes care of all of the hydra. 😉 Cheers, Chris

Wait, are those patrons listed at the end for just this channel alone? 😲 Didn't this channel just start a couple of months ago? 🤨 That this channel gained that many patrons from it's still meager 222K subs in just a couple of months is a real testament to this channel's magnificence. 👍 (There's got to be some sort of record there. 🤔)

Predictive programming. He's owned. Funny you would say all that on a hydra video.

[@vivianeb90]

Another amazing video. Please, make one of stuff you found on a human eye!

[@marquepoolejewer9427]

What a great explanation, Thank you

There was once a hydra outbreak in my aquarium which is where I keep all my shrimps in, it is viewable without a microscope and there were tons of them , they are especially good at killing shrimps and I had to use anti dog parasite drugs to treat the tank

That time when you realize that the pictures you saw in your science book, when you were a kid, were made by excellent artists!

[@danielnewhouse7033]

It's probably a dumb question but could you explain what causes the movement in these guys

[@bennyapostol4231]

I love Hank's cadence here, so appropriate and enticing to listen to just like in crash courses! :)
