@sarenbinkerd4162 I agree, it's a combination of hearing Hanks calm voice describing things and a moving color scape of things being described: overall a calming relaxing intake of information 🙂.
@@culwin it sure does. But that doesn't make their experience with Hank being in many videos they watch and that making them happy any less valid or enjoyable for them.
@@culwin did you know every single thing you watch is pre-recorded? Unless it’s a live stream I guess, but you can still watch those after they’re recorded 😂
I am always glad to play a few videos of Microcosmos when I have a migraine. Hank's voice tends to calm and center me,the background music is pleasant and the visuals are relaxing undulating colors. ( I can always go back again and actually watch/ listen). 5/29/23 Hank I hope you are fairing well this week 😊.
I will always have a soft spot for Hydra oligactis! I did my bachelor thesis on them and was lucky enough to publish it. Such cool and strange animals! A little annoying to keep in the lab though hehe
If your old friend @zefrank hasn't made a Hydra video he really should. Those spinning balls are amazing. How they rotate so fast and either stop or instantly change the spin is fun to watch
Lack of senescence is both a blessing (on an individual level) and a curse (for anything at the top of the food chain, like humans). Having just completed my 60th solar orbit and having led an active, event-filled life, I'm at this point full of shrapnel and many broken bones that have healed with varying degrees of success, plus ALL my joints have been sorely abused. If I'd known I would live so long, which I never desired and in fact attempted to prevent by my chosen professions, I'd have taken better care of myself. So yeah, I give props to the hydrae for not having to deal with the increasing insults of old age. But OTOH, there are already, what, 8 BILLION of us at last count? And everybody agrees that's way too many. On land at least, we have no natural predators apart from disease-causing microbes, so nothing but murder, accident, disease, and aging kills us. So do you really want to grant immorality to humanity as a whole? And if you do, then do you spay and neuter everybody then alive so that the population slowly declines due to accident and murder? Or do you just give immortality to the wealthy elite who have no qualifications to be god-kings other than being rich and seeking personal aggrandizement? IOW, Warhammer 40K made real? So, when I wake up with aches and pains, I envy the ageless hydrae. But when I actually think about it, I realize my aches and pains are honorable scars and I'm still here despite all life has thrown at me. Old age isn't for the weak. Not only because the weak died off earlier as Darwin dictates, but because it's the ultimate struggle. Which we're all going to lose, but we're only in that ring because we fought our way into it over decades, which is something of an accomplishment. But Father Time and Old Man Death are undefeated. So prepare to give them a good fight, maintain your dignity as long as you can, and then accept the inevitable outcome. All that said, I do NOT envy the hydrae at all for their self-hurting butt-mouth. Even if I had to rip my lips apart every time I wanted to poop or eat, I could tolerate that except that the poop would have to roll out over my taste buds. I hope hydrae have none of those, at least in their cul-de-sac of a digestive system :)
Sex in nature is WILD all parts of the world Because sex is the whole point of all organisms even us Our only reason we live is to have spread our genes and survive But the the human brian found a way to do more than that
I'd think the hydra dying when reproducing in a cold environment makes a lot of sense: not only is there a bigger challenge ahead, cold environments fundamentally have less energy/food, so clearing space for the newer generation might be required for there to be enough food.
It makes kind of sense to me. If the Hydra clones itself the offspring is equal to the parent because they share the same DNA. But if they sexually reproduce one of the offspring can be better adapted so it might make sense to focus more energy into producing offspring rather than surviving as an individual and possibly competing with your own offspring. But then again I guess there are plenty of species that die of old age without reproducing sexually.
Senescence helps prevent parents from competing with children. Perhaps this allows species to adopt new mutations and more quickly adapt to changes in environment.
You can ask the same immortality question of bacteria which only reproduce by binary fission. They've been dividing for a gazillion years... so, immortal? If we're talking about a SINGLE cell living WITHOUT renewing by division or whatnot... then the closest we can get are those bacteria found deep in the rocks of the crust, which may not divide for a MILLION YEARS.
Seems like a mix of evolution for survival, and random changes. It will be more interesting when we have colonies of hydras and other species living in space, and perhaps on the moons of Saturn along with Earth's moon.
oh also don't forget the aboral pore of hydra! it doesn't get mentioned much, and it's worth discussing the importance or innocuity of it for the sake of evolution and physiology.
Hi. Which microscope are you using? I am looking to buy one for home use and I am kind of confused which one to buy. Also I have noticed that most of your videos don't exceed 1000x. I am assuming that would be enough magnification to see what you see? Many thanks in advance.
Aging is like planned obsolescence, it's supposed break down to make room in the market for the newer models. I don't think there is a physical reason an organism must die, sure you have the telomeres and accumulated dna damage but there are systems that can keep these thing in check forever... but they don't, imo aging is an evolved survival strategy for a species, the reason? well the obvious one is making some space in the niche for the new generation, but i might have many more like to control parasites or predators populations or maybe it's a way to ensure a species puts enough energy into keeping their reproductive cycle evolving fast enough for their offspring to still be able to adapt to the changing environment. Imagine an impossible hypothetical world where there the surface is totally leveled and the is one inch of water, the only species are inmortal mangroves like trees and they completely block out the sun, the seeds fall sprout but seedling never fully develop because the lack of sunlight, slowly through milenia the water level rises, this has no effect on the trees because they are tall and strong but the seeds eventually can't anchor themselves in the mud because their spike isn't long enough to reach it. After a long long time something happens, a weather phenomenon or something, all the trees but a few lucky ones die and there is enough sunlight for the seedlings to develop, but they can't because the water level is to high for them to anchor themselves. The remaining trees keep living, maybe forever, they keep producing a ton of seeds but the niche for the life stage of the seedlings is gone and there isn't enough genetic variation in the length of the seeds for them to reach the mud and never again does a new tree ever reach maturity and produce new longer seeds. If the trees weren't biologically immortal the species as a whole would have been fine because their reproductive strategy would be constantly tested to adapt to the changing water levels. Water level is just an example, it could be salinity or temperature or whatever.
The problem with this idea is that evolution doesn't plan ahead or act in a manner as if it were thinking in global terms. Evolution only favors the next mutation in an organism that improves its fitness in its current environment, not in anticipation of any future eventualities or later mutations or changed environments. Evolution can't 'see' your hypothetical world and implement changes to prevent it, it only works on the world as is and the organism (not the species as a whole, just each member of it) as is.
@@ArawnOfAnnwn I think you missed my point entirely, which was to summarize... aging was evolved and it serves a purpose, in other words it's not a bug it's feature haha and it's in no way detrimental to a species. I never said it plans ahead, i know how natural selection works and that it's not a conscious process. A species WHOLE life cycle needs to evolve with the changing environment.
@@ArawnOfAnnwn There is always the energetic side. It would cost a great deal of energy to make a human immortal plus 405 of our energy is to do with maintaining our brain.. We are much more complex than hydra (as said: a Monostome; only 2 germ layers/diploblastic; no bilateral symmetry; no central nervous system; no 'animal body plans/Hox genes; internal organs etc.) Basically it takes less energy and organisation to indefinitely maintain a hydra. The same for it's relative the Immortal Jellyfish. However: can we call the 'germ line' immortal?
Variation according to an environment under varying conditions as a whole so on a quantumcosmic scale our evolutionary path established according to our very nature as living beings no matter what changes are being made going against the grain machines being a degenerate trade-off life keeping to its perfect rhythm to reach its destination is most hardy and cannot be compromised!
The aging is just a evolutionary feature, clearly the particular species has an annual lifecycle, most likely because it would not be likely to survive the winter conditions anyway, so it makes sense to put 100% of its resources available into sexual reproduction, resulting in more offspring produced; versus a perennial species that will never devote all its resources into reproduction thus produce fewer offspring. And when adverse enough condition occurs that will kill a large enough amount of adult individuals the annual species will always out compete the perennial ones.
Hahahaha luv it . Butts n poop make me insanely crazy and loose the plot every time 8 hear the words. Omgoshhhhh .hydra butts n poopa just saying! Hahaha
Up the temperature, fairyshrimp can probably survive much higher temp than hydra. Probably. In my experience hydra flops over and dies when it gets too hot.
imagine if we would also not age or age significantly slower like abraham in the bible or so idk if we would do infinite semen retention, but because no one does it we dont know
The reason for the decline can be agrued for the good of species as a whole. If the hydra nevers dies from old age, then how are the new babies supposed to grow up. They'll be competing for the same resources with the parents. Sexual reproduction is for change in the species because it's stressfull. Asexual reproduction is for stasis because there is no need for change.
EXCUSEEEEEEEEE MEEEE!!!! Again with mentioning in the title or description about butts THEN HAVE THE AUDACITY NOT TO SHOW ME A BUTT!!!! Hank your doing me a doosie I'll always keep watching although I'm getting quite annoyed at the lack of buttholes and pooping...

You mean book, right? He doesn't make music.
@@mh6276I suggest you google Hank Green music
Reading the title incorrectly as “butt sex, immortality” gives a wildly different impression of what the video was about 😂
Someone once said, that a dirty mind is a joy forever.
At first glance I read "immorality". Been arguing with too many fire and brimstone bigot right wingers online I guess!
Jajajajaja literal... I read: sex, butt & immorality (not immortality)
If your old friend @zefrank hasn't made a Hydra video he really should. Those spinning balls are amazing. How they rotate so fast and either stop or instantly change the spin is fun to watch
_Hydra_ are some of the most awesome denizens of the tiny world. Good to see them getting more rep here.
"How was your date?"
"Ugh... he was all hands., and into butt-stuff."
3:24 They are their own entities. Otherwise there has been only one in history, as the one it separated from would be part of the original also.

Hank Green is like if Willy Wonka was a scientist mixed with the calm of a Bob Ross painting tutorial.
I think this might be the best description I've ever seen of Hank! 😍
*Wolverine:* _punctures a millimeter of skin_ "Hurts every time." 😤
*Hydra:* _tears face/butthole open_
"Sex, Butts, and Immortality" sounds like the title of an avante-garde music album
I have head that in some studys it was found out that hydras in fact age over time.
They regenerate slower and slower and can die of old age too.
There is something called genetic entropy which means that there will be eventual degeneration and extinction
Nice to hear Hank's voice 😊
Best comment section on TH-cam
Hydra sex is way more wild than I expected.
It literally is.
Sex in nature is WILD all parts of the world
Because sex is the whole point of all organisms even us
Our only reason we live is to have spread our genes and survive

❤ Hank...this is the channel I fell in love with you!
I have a bunch of Hydra viridissima on my windowsill aquarium right now. Love them
Fantastic job here, Microcosmos team!
1:35 the automatic subtitles say "fatalistic" and that fits as well, haha

Senescence helps prevent parents from competing with children. Perhaps this allows species to adopt new mutations and more quickly adapt to changes in environment.

Hydra on cold water "oh the water is too cold I'm too depressed to eat let's just sex and die" 😂

I've always been fascinated with hydra, they seem like they have so much potential for scifi creatures
Butts. The gateway towards interest in science.
Three of my favorite subjects.

So what I’m hearing is I need to come back as a hydra if I’m gonna be gay.
Anyone else hear Markiplier's voice "Have you heard of the ship of Theseus?"
When the hydra tears it's mouth/anus open to eat or excrete, how does it keep from getting infected?
Hank, you are talking quickly in this one.
