Me: "Time to go to sleep" Journey to the Microcosmos: "Crustacean dong" Me: "Ok, i'm listening"

My man dumped all of his stat points into the reproduction!

I'm 34 years old. Nearly 35, and I'm reasonably sure I will never be mature enough NOT to giggle like a child at the word hemipene. That's just..... hilarious.

The amount of footage you got of that one ostracod circling a grain of sand over, and over, and over, and over again is just hilarious. Look at him go

How am I supposed to ignore a title as intriguing as this one?

I've been searching 30 years to the answer of this, one of life's most meaningful questions: "what's the oldest peepee?"

We had an infestation of these guys in our aerobic digestor. We had a strange film of bubbles on surface and couldn't figure out what was going on. Turn on the microscope and we see that there were so many of these guys their shells formed a layer over the entire surface. James was right, eats everything, and swims in poop.

They are good if you are growing plants in water and need something to consume stuff to create fertilizer for the plant roots. (aqua-culture).

"Um... Dad? Am I allowed to watch this one?" -My youngest daughter, after reading the thumbnail

Most ostracods are indeed tiny, but the one you illustrated at 3:43, Gigantocypris, is the size of a marble. It is a mesopelagic species with enormous eyes which show up well in your illustration. A nifty animal.

This really stirred up some memories. I swam and dove competitively as a young man, and during a gala in Latin America, when I was up on that diving board, feeling stiff and exposed in my Speedos, people began chanting 'Colymbosathon Ecplecticos!'. I didn't know what it meant then, but I felt empowered and encouraged. I truly miss those days; thank you for the memories.

I was hoping this would be more about ostracods and less about their reproductive organs. Maybe we can get a part 2, about their lifecycle, favorable and unfavorable habitat conditions, preferred foods, things they won't eat and so on. I know other people have established this information, but I would like to see what SciShow/microcosmos would contribute.

The title got me 😂 Figures Hank was not the narrator on this one 😝

Great, now even a 2mm clam shrimp hybrid is making me feel inadequate.

James’ quote among other things had me laughing at this one a lot. Well done.

This is one notification title that I thought I would never see in youtube!

Ostracods are one of my favorite invertebrates! Ever since I got a call from a friend about some bugs that turned out to be ostracods inside an aquarium I've been so interested in how they can seemingly turn up everywhere and survive just about anything!

“with a long… history” - I caught that playful intonation there… ;) 🤣🤣🤣 - Fantastic job again. Thanks!

"Hemipeenies" I'm dying of laughter! Best mispronounciation(?) ever, 10/10.

THEY ARE SO CUTE IM CRYING. THEIR LITTLE LEGS PLEASE😭

Sooooo... Are the two halves of the ostracod shell called "cod pieces?"

This is quickly becoming my favorite channel. I've discovered James' original "Single-celled Organism Dies" video a week ago, at about 1 AM, and it made me think for a good half hour about what death is. I then looked that phrase up and stumbled upon your "This ciliate is about to die video". Only binged videos from there, stood up all night. Great work guys.

“The large, muscular sperm pump”. Huh, reminds me of someone

Hank: Look what I found! James: Oh a floating sperm. Hank: Wait what???

Ostracod enters ... Other microbiology: oh, we are fu**ed, LITERALLY.

"Is it worth it? Let me work it I put my thang down, flip it and reverse it Ti esrever dna ti pilf nwod gnaht ym tup i Ti esrever dna ti pilf nwod gnaht ym tup i If you got a big, let me search ya To find out how hard I gotta work ya Ti esrever dna ti pilf nwod gnaht ym tup i Ti esrever dna ti pilf nwod gnaht ym tup i Come on!" -Some Ostracod, circa early mesozoic era

It was nice to hear Deboki again.

Wow Hank! Your voice on this new microphone is so suave! 🤣🤣

the philosophical question of whether evolution is "worth it" is very interesting--but I think it's misleading to frame the genetic shifts of a species as "choices". an ostracod doesn't "decide" to be mostly reproductive organ, it's that way due to genetic and environmental factors. and the proliferation of a genetic trait within a species does point to reproductive success, at least in a short-term sense. if those mutations also lead to lower lifespans and survival rates, then the fascinating see-saw of evolution begins; some species and mutations will reach a survivable balance, and some will disappear.

B I G N U T yes, I'm a child, and I'm 29. It's never not going to be funny.

Those poor lonely, hairy, poopy Lima Beans !!

It's bigger than mine.

Something about an ostracodpiece…

So size does matter... My whole dating life was a lie. She will be happier with a Ostracod. bye world

Your videos popped up in my feed and loved them! My understanding of a single cell organism at that point was a blob of gunk with a dot in the middle surrounded by a wall or film. I could not understand for the life of me what the wriggly bits were (Flagella) and that has sent me on a 3 day binge of learning! Proteins have now captured my imagination and I will be looking into these a lot more. I am absolutely fascinated, and it's all thanks to you fine folks at Journey to the Microcosmis.

They used to call me the "large, muscular sperm pump" back in college

7:24 Lowkey thought the narrator would say "a remarkably well-preserved animal with a long 'penis' ", again.

Ostracod was my nickname in College 🤥

You guys were my inspiration to order a nice swift microscope, your work is absolutely incredible and, in my opinion, undeniably important for public education into a criminally unknown science!

Thanks for the awesome content!!

Congrats on 600k🥳🥳

They make good pets. Almost unkillable. If they have water, some sort of dirt sand or gravel underneath them, and literally any water plant, they will never stop making new generations. Find the 2mm ones if you can, they're more visible than they seem. Pretty cute too honestly.

I guess this is more of a channel for viewing and identifying and less about raising at pets. A while back, I collected some pond water and saw them and got help identifying them. I thought I wanted regular small shrimp, but I found out that ostracods are a better option for little "bucket ponds", because they are lower on the food chain and can thrive in conditions that actual shrimp can't survive in. One thing I should mention is that if you go somewhere and find them, don't expect to be able to go to that location year-round and find them. Make some sort of note about the date and time of day you find them. Weather conditions can also be helpful if you want to document that. I went to a pond and they were everywhere. It was impossible to collect water without collecting them. I went maybe 2 months later (i don't know the time frame) to get more and there were none at all. Ostracods seem to prefer to stay near the surface of the water, where they can hide within duckweed, azzola, algae and other dense plant material, but they aren't in any way restricted to that area. A problem I had with them, is that they would end up getting stuck above the waterline, to the side of my aquarium. There is probably something simple that could be done to prevent that from happening. Maybe aerate the water in a way that doesn't create bubbles in the area of the ostracods.

It must be worth it if they've been around for 450 million years.

You guys should leave a cup with coke in it or any soda out on the counter for a week and then look at the bacterial blobs that form in the soda. Do different sodas form different bacterial colonies?

I had a microscope out of a science kit years ago and used the hell out of it then lost it while moving, I will definitely have to pick one up again. I feel like I am missing out so bad lol, there's too much to discover

this channel is so great omg

Love these videos

Cientist: Was it worth it Ostracod? Ostracod: Ask your moma.

Brought a smile to me; I did my Master’s on Ostracode morphology and shape analysis of a species. Thanks for the video.

Guess I need to delete my History after I watch this one! 😂 Fascinating!

I’ve been waiting for this

great shit!

Giant and old? It could be any one of us!

Fun fact: ostracods can survive being eaten alive and even bring down worms and fish, attacking the weakest parts of the animals. During a night dive in Panama, a diver's ears, hair and beard were covered with ostracods, forcing him out of the water.

i love deboki’s narration. hoping it becomes a regular thing!

Even Nature is trying to comfort mankind by saying: _"See, dude, it's not the size what matters but what you do with it; at least you're not swimming in your own excrement...well, unless you live in Baltimore, but I digress."_

Yep. I did read that correctly 😂

I am right now exactly 3 minutes into the video and am already laughing out loud while thinking about the comment section.

My ancient ancestors were microbes 🦠 Yes, that is my family tree. 😀👍🤗😎

2:49 what a coincidence that’s also what your mother calls me

You guys must have had this request before, but is there any way to show us Sars coV2 through your incredible imagery?

new narrator has a very nice voice! i wasn't sure about her in the first few seconds but she's got a super calming voice. i like it

Colymbosathon ecplecticos is my nickname too funnily enough.. 😂

Ostracod ... aka, water humans ( regarding eating and pooping till nothing is left in their environment)

An absolute mastery of the clickbait title/thumbnail combo

Wow, this thing is CUTE!

This channel is perfection! Could you cover leukocytes and cancer cells? Maybe both and have them brawl?

Love the idea that selection for sexual dimorphism doesn’t give a damn about species survival. Short term gain over long term sustainability is so typical.

These are actually a mild pest in pet ornamental shrimp tank, they eat all the food for your baby shrimp and reduce their rate of survival 😭 glad to know they annoy another field as well

Very cool!

For an microbe that ain’t got no trouble laying down that water pipe, how certain species go extinct makes my head scratch.

Just an FYI: direct mutual aid works better than charities. There's no pimp. Just money right to those who need it. Ask your neighbors if they're ok too.

It probably goes without saying that the age-old dispute of the existence of *"Hemipenes Envy"* has not been put to rest.

The video deserves a like just by the title alone!

Finally, an animal that resembles my own bodily proportions!

An interesting reminder that the (considerable) enjoyment value of watching these things is still only one part of it. The microscopic fauna puts some biological issues right at the table for studying and are also often easily comparable to fossilised specimens. While a bunch of bones from the Permian might tell us something about questions we have today, provided we interpret them right, animals like these speak clearly.

Wait, I'm confused. The ostracod can get up to 2mm in length...but its sperm can get up to 10mm? 3:30

This is something right here

Oh, subscription feed how I love thee.

James thank u I love you

Trade 'ostracod' w/ 'human' & see Our situation thru-out this video: That ostracod eyespot is so cute 💜.

At first, I was surprised that Deboki was narrating this one. Makes sense though! Given that she studies biomechanics. Erectile tissue is one of the most interesting structures in nature, isn't it?

Tasteful thickness.

1:18 Metroids are real!

Hungstacean

The peacock tail feathers grow fast and drop frequently and if grabbed, they'll all drop. They can also fly with those tails . The expense to a peacock's survival is to eat enough to replace the damaged ones, or ones that have let go to a hungry animal, more than it's a liability. Predacious animals are afraid of eyes too, so it can be a defense mechanism. This is how it's able to survive with it.

I so much would love to know more about what techniques were used to get this image? Is it just that my miscroscope and objectives are of less quality? Is there a filter that I don't know about? Are the videos digitally enhanced before being posted? I need to know ^^ Does anyone know more about James's process?

Alright, alright, you've got my attention.

"Large muscular sperm pump" is the nickname my gf gave me, what a coincidink.

"large muscular sperm pump" is a masterful non-euphamism

That's what she said

Spore game in real

I’m wondering when the first STD developed and if there are any known examples fore Ostracods

There are old pilots and there are bold pilots. But there's only 1 old and bold pilot... 😄

I've not read the 2018 study but I find it a bit bunk as described. The evolution of a species isn't a coordinated affair; it is the organism's genes vying for survival. The gene’s in favor of significant investments in sexual reproduction are pressing for their own survival not the long-term stability of a particular species or phenotype. Gene lines can and often will have many terminal paths, but as long as some lineages live on they continue to be successful.

Don't let anime illustrators to have this knowledge

Ohh should have read the thumbnail before I click that in class lol

Ohhh things escalated real quck lmao...
