- Did you know that four out of every five animals are nematodes? But what is a nematode? This animal predates the dinosaurs and they outnumber humans by trillions, yet you might not ever have the pleasure of seeing one. So let us introduce to you in this episode of SciShow, the infamous nematode.

Watching this while eating tube-shaped pasta may not have been my best decision today
Bon appetit, mon amis! I hope you will always remember not to think about nematodes before eating tube-shaped pasta! 🍝🙏
Stop whining and eat your worms
Oh gosh, now I’m hungry😯
@@nancykurtz7333 I was having a pear as he started talking about how nematodes could have been a covering the planet and kinda is. I am full now 😂 pasta is cooked. I could definitely go for that! 😋
At least it wasn't vermicelli.
For most of us, our first encounter with nematodes was watching them drink Spongebob's house.
I was waiting for a spongebob related comment!
Dude you are so right.....wow
🤯
Try Doug. Like a decade earlier
@@MrYTGuy1 I remember Doug and Skeeter lol
I don’t like nematodes... they really destroyed my boy spongebob’s house
I hate sand.
@@paulgoogol2652 same .
Danged nematodes
Paul Googol it’s course and rough and irritating and it gets evwrywhere
i forgot about that episode of spongebob until you said something :P
There is also a nematode that has specialized itself to almost only live on German beer mats, drinking the yeast they love alongside German beer drinkers. They're like pets we didn't even know we had.
Dang, that's kinda crazy.
Well then, Prost! : )
Little drinking buddies :)
345th 👍
Nor wanted.
Never seen? I've seen them destroy a pineapple
Avery the Cuban-American nematodes made and ended that episode
@@archenema6792 hi, havent enemated in i while, how is it flowing?
I'm crying 😂fear the nematodes before they make you homeless
And the whole bottom of a bikini
I only clicked on this video in hopes someone would make a reference like that haha
so what i have learned is that everything on this planet is either a nematode or its not.
And each and every thing that exist is surrounded by at least 50 billion nematodes
Everything in the world is a penguin or is not
All of these things are correct. ☺️
Yes
You might also say that everything on this planet is either a nematode's food or a nematode's toilet. Or both.
“57 billion? I mean that’s a bunch but not.. that much.”
*per person*
“... o”
Imagine not all person have,
We all have at least 1 nematode on us. I think I'll call mine champ.
@@lunar58071 i call mine poggers. Hes a feisty lil bugger.
@@boooomerwang im gonna call mine steve
Just call him Fred.
Find Nemotode:
*Points to anything*
There he is.
Lol
Look at him go
I'm a C. elegans researcher, thanks for giving this little worm some love!
:0
Cool
what’s your research in?
@@yourfavoriteweapon92 Stem cell regulation.
Saaammmeeeee
8:46 crawls? WHAT DO YOU MEAN IT CRAWLS
8:53 dont leave without explaining! get back here and explain how it crawls!
He explained it moved like an amoeba. I can't describe what it looks like, but there are videos on TH-cam, just search amoeba moving
They mean the sperm
Pseudopodia is how it moves
There is a species that can literally fling themselves 7-10 times their body lenth. Idk why he didn't touch on that.
@@cmdann8 Now I'm picturing a living slinky.
"4 out of every 5 animals are nematodes" glances over at five of my coworkers...
😂
Nematode scientists are studying humans for going extinct.
”There’s only 10 billion of them”
”Wow, that very litlle :(”
Clearly anything that's not a nematode is endangered
Imagine their reactions during the extinction of other animals species
God: so what do you want your design to be??
Nematode: a gut
God: ... okay, and where do you want to live?
Nematode: everywhere
God: alright...
Nematode: including guts
50% guts, 50% genitals, humans will thank later

@@sendmorerum8241 speaking from experience, getting both at the same time really was not a good experience in the slightest 💀
Number 7: Beneficial nematodes are helpful to lawns and gardens. There are products that allow you to connect to a garden hose, and spray them on the soil (has to above 68F soil temp). The nematodes will invade larvae of pests like Japanese beetles, grubs and other harmful insects. The nematodes will lay eggs inside the grubs and eat the larvae from the inside out.
I for one, welcome our invertebrate overlords.
(keep this one away from the water supply)
Collaborater!
All hail our nematode overlords.
HYPNOTOAD WANTS YOU BZHZHZHZHZHZHZZHZHZHZHZ
@ERA CASTE depends on your cleaness you can get rid of them with medicines
I did my Master's research project on the C. elegans nematode species. You want an idea for a horror film? An agar plate visibly squirming because it has been 7 days since you placed an initial colony of 5 worms on the surface. Note: an adult C. elegans is about 1 mm long so if you can see the agar plate squirming with the naked eye, that's A LOT of worms sliding over each other.
My professor told us at the beginning of the course, that when students get to see the worms for the first time, there's always this one person, that's has a fright at the sight of the worms and needs to go outside and calm down 😅.I know what you mean with creepy. We also worked with a.strain that has no vulva, and when our professor told us, that these worms don't lay the eggs- because not possible- but instead the worms hatch and develop inside and the mother just bursts and they go free, there was kind of a silence in the room....so yeah, nematodes are perfect horror creatures
You wonderful people 😅 here I sit, studying for my C. elegans theme test, and see the notification of your nematode video! That's irony, isn't it? And yes, my professor, who has been working with C. elegans since 20 years can tell you for hours about their importance as model organisms, especially in cancer research. She studied them in regard to the control of their assymetric seam cell (stem-cell-like-cells) divisions to find genes regulating those divisions.
I love SciShow ❤
What an amazing coincidence!
@@wonderwend1 Truly, 😅 I forwarded a link to the video to the whatsapp-group of my course. Probably everyone is studying for the test right now.
Good luck on your test.
@@qwertyTRiG Thank you🍀 It's on Thursday, so I still got time to study.
If you ever want a chuckle, look up the Worm Shows from Curtis Loer and Morris Maduro. It is incredibly nerdy and niche but people who have studied C. elegans will appreciate the jokes and humour.
I get it, Thanos was sick of them nematodes
[sun goes nova]
[nematodes colonize the sun]
They are quite fond of pineapples i hear
Oh really?
This pfp with that reply makes this seem even funnier.
im goona go get a tube of apple flavored horse dewormer from the farm store and eat it.
Hahaha jesus alright
*death note reference* Kira kills me because of my various warcrimes
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 I can only stop myself from thinking way too hard on how to make an antibiotic consumable for all possible hu-mans/ wo-mans/animal/mammals and basically any living creating these little hungry hide and seek slimey friends invite themself over to Thanksgiving turkey gutting 🤣 awe LAWD, I have to do some house cleaning now! 🤣
Hank, you need to plug your Journey to the Microcosms show, its stupid interesting and really cool to watch. If any episode is appropriate for a plug, its this one.
Just checked into Journey and subscribed immediately. Thanks for the heads-up.
Worms are everywhere. You cannot escape them. You will not escape, not even death will save you. Give in to the worms.
Me: Starts the video
SciShow: Opens a can of worms, FOR SCIENCE!
You got me at 8 Billion People & 57 Billion Nematodes. I was thinking “Ehh, that’s not that much.” 🙂
Per person
Im so happy to see these squiggly bois getting a bit more attention. They're a large focus of my research in Stockholm. They're incredibly diverse but tricky to properly capture and classify unless you're a true nematode veteran.
So my team and myself are currently using metagenomic (metabarcoding) techniques to get a better feel for their diversity. This way we hope these guys can tell us more about the environments they inhabit.
There fast to
updates, any special findings?
You should make a TH-cam video that's less annoying than this one
Ive seen these bois from spongebob my dude
Nice.
I've seen several... on Journey into the Microcosmos.
Yeah! They are great! 🥰
Best channel EVER!
I legit thought this was that channel and was like, "what? Yes we have.". Then saw the intro.
Hank Greens voice is like a satin sheet against my bare eardrums

i recently set up a couple small vivariums with soil, plants, and fauna found in my neighborhood and i've noticed tiny nematodes squiggling around in the condensation on the walls. after i first noticed them i began to notice more and more, they really are everywhere.
"I for one welcome our nematode overlords." Put that on a T-shirt! 🤭
Me: *watching video about worms*
My brain: ALASKAN BULL WORM
Listen, I know the nematoads.
I watched them eat a house once and it scared me.
what ?
@@parisamerie SpongeBob reference
I literally just came inside after turning my marigolds under in my tomato bed to combat nematodes, then I saw this video. Weird flex, Universe, but OK.
Many years ago, I saw a short nature film called "Nematode". Each section, such as Motion, Eating, Reproduction, etc. was first shown with a clay model nematode and a few props, then a clip of a nemotode in action. All this accompanied by the music of Mozart's Variations on "A Vous Dirae Je, Maman", otherwise known as Twinkle, Twinkle, Little Star. An interesting introduction to a piece of classical music! 😁
Fascinating video! Now my entire body itches.
At the beginning of the video : god, I love science
As it gets creepier and creepier : what the eww !
That's science for you!
"Roxane! RoxAaAne! All she wanna do is party all night.
God daaamn! RoxAaAne! Never gonna love me, but it's alright."
“Doug Bags a Nematoad” was the very first episode of Nickelodeon’s Doug back in the early 90’s.
Finally, a man of culture.
Lol. Yes it was.
**cue Spongebob comments**
Meep.
Nah, I was thinking of Doug Funny first lmao.
still hungry!
@@autobeemations5913 still hungry
Nice synopsis on Nematodes Hank! As an undergrad at the U of MD I took a few Parasitology courses & one of our professors was responsible for not only figuring out the life cycle of Heartworm disease in dogs but also was instrumental in developing a drug to prevent the infection. The culprit is the roundworm Dirofilaria immitis which can infect Dogs, Cats & Ferrets. It is transmitted via Mosquitoes, as are many diseases. Nasty little critters but still part of the natural world around us!
Scishow: "The world is covered by tiny unnoticed roundworms!"
Me, an intellectual and MLS: "ANCYLOSTOMAAAA"
Hookworms for days
Fun fact:
There's enough nematodes on Earth to send roughly *1 billion to each star* in the Milky Way Galaxy
Yep there about 400 quintillion of them
let's do that.
I love your show. I usually click "Like" even before the intro jingle is done.
Also common in the marine environment, Nearly all seaweed samples I collect there are nematodes present.
Doug Funnie once caught a nematode. Legend.
If you don't know about really tiny animals, there's a TH-cam channel all about them, called, what is it... "Travels through a Microscope"? Something like that. The narrator there has the nicest, most calming voice, too.
Nah, Pretty sure it was "Migration with Microbes."
@@PopeGoliath Yeah, "Migrations" sounds better than "Travels". ;)
you had me at *nematode overlords*
I love this video! Best one in a while! Super interesting, long, and engaging. Keep it up!!!
Very interesting episode! More like this, please!
Hey, I thought Journey to the Microcosmos wasn't going to update this week... oh, this is SciShow.
My father's favorite nematodes joke:
You're studying to become a civil engineer. It's a Sanitary Engineering class you're watching a video of a microscopic sample of sewage. Student in the front: "Sir why do these nematodes wiggle around so much?" Student in the back: "You would too if you were living in nothing but poop."
It's a true dad joke.
I hope to hear hank talk about this again on into the microcosmos
Assuming the audience of this video hasn’t seen a nemotode is a misguided assumption. 😉
Hi Cody, How have you been doing brother?
Nematodes: living proof of "if it ain't broke, don't fix it"
Are there viruses that prey on nematodes? Do other creatures? How long do/can they live? I have so many questions!
Great question! That’s actually, seriously, interesting to know. I mean if so, it doesn’t seem the Nema family has ever had to make much of a competition or plan for battle against any possible attack. They seem to expand their Nema army larger than any other living mechanisms this well blended in their incognito slime suite and way of traveling to and fro
If I recall correctly, we NEED some of the nematodes here. And some of them eat other kinds of nematodes, too, IIRC.
@@brittstates9607 There are types of microscopic fungi that constrict and digest a nematode.
Anyone else up for the Beets concert?
And if you genuinely do get the reference and relation then you are awesome and probably a 90's kid too.
Oh Doug....
Like the sugar beets?
I need more allowance!
Glenn Griffon , my nematode call: COOO-A-COO COOOOOOO!!!
COOO-A-COO COOOOOOO!!!
Aahhheeeeoooo, killer tofu!!!
Hank: Nematodes
Everyone: Spongebob
Me: Flashback to parasites
Nah, not everyone. Some of us were lucky enough to miss that whole mess... like, we are too old, and our kids were too young, to get into the show, so it all worked out. Thankfully, LOL!
I learned a cool nematode fact recently. There is a nematode species that makes the vitamin B-12. Many animals have evolved a symbiotic relationship with this nematode, one of which is humans. Unfortunately, our B-12 nematodes live in our small intestine and the B12 they make can't be absorbed. Lucky for us, though, ruminates, like cows, can absorb the nematodes' B12. B12 deficient humans still have B12 in their feces, because it's made in our gut, just not absorbed. This is not an endorsement of eating your own poop for B12, though.
1:44 I'm outa here.
1:50 Ok, we have to nuke the solar system ... there is no other way.
*You nuke the universe but some absorbed the radiation and increased in size by 900000000 times*
Worked on a dissertation project on C elgans in the final semester of Mol. Bio course and instantly fell in love with them.. Continued working on the project after that for more than a year.. beauty about the organism is, in a way they reply to you or communicate to your signals ( I know I'm a hopeless lonely individual).. Unfortunately, they are much lesser known than drosophila or mice and people tend to get disgusted by the idea of working with a roundworm or when they see worms wiggling under the microscope. This video marvellously extrapolates the dynamic world of nematodes.. Keep up the good work! :)
you get excited about the weirdest things, Hank. I do love you for that... still weird, though.
Yeah, I love his charisma
First time I heard about a nematode was in Doug, but they spelt it "neematoad".
I remember studying these WAY BACK WHEN! We were supposed to see them crawling through a jungle of fungal hyphae and then getting caught in a hyphael "snare" and subsequently devoured by the fungus. Uh uh! The nematodes that we were given were MUCH TOO LARGE to be caught in the snares that we saw. We needed a smaller gauge nematode! I was disappointed!
For some reason the crawling sperm creeped me out the most
This is the best informational video ever about the C. elegans, THANK YOU SO MUCH!!!!!
i was literally eating spaghetti and meatballs when i opened this video. i may never eat again.
Excuse me, Rodger Klotz taught me about Nematodes back in the early 90's.
This was fascinating! Such a great video
Fantastic video, thank you!
Splice a chicken and nematode, I'm down for 24/7 omelettes.
The chicken salad sandwich that eats you... From the inside. ..
heart disease
Imagine if H.P. Lovecraft learned about Nematodes.
Good grief... the horror stories would've been unimaginable. *shudders*
Great summary thanks dude!
Impressive video! Thank you
What you mean I’ve never seen nematodes?
They literally drank SpongeBobs house to death - mischievous creatures, those nematodes
8:23 worm on a string!!! REAL
God i remember those things
Thanks for this video. It is just brilliant!
Always interesting, thanks.
Doug has tried to catch these. Who remembers
I did! I hear Nematode and I remember that first episode of Doug.
Would you like some... Basghetti?
Sure
You're eating... Worms!
Man imagine humans excreting urine from their sweat glands. We would have invented perfume way earlier.
Impressive numbers. 🤯 Nice video, guys!
I waited the full episode for a plug of "Journey to the Microcosmos" and IT NEVER CAME
"All i have is this little pebble"
Wow, so interesting !! Great episode !!
i dunno why but seeing hank geek out over nematodes is just super entertaining!
Is anyone else thinking of that one episode of Doug?
I wonder how many undiscovered ancient nematodes are inside insects inside amber... 🤯
I am into ecospheres and active in various groups. Every time nematodes come up I post a link to this video. I have referred at least 5 dozen people so far ..love it!
Well written and presented video
I learned about these watching Doug
Finally someone else that knows this came Long before Spongebob!!!
I actually saw some nematodes during my high school "Biome in a Bottle" experiment. The teacher called everyone over and we got to see something nice.
best SciShow episode i've ever watched not only was it interesting it was hilarious
Love this educational channel

Funny! Awesome!
Thank you!!
Saw Nematodes. Thought of Doug
So is there a Tardigrade specific Nematode?
Me eating pizza while watching this vid: “I hope the nematodes inside me like this snack”
That video was at the same time, extremely funny, and completely filled with crazy fact I had no clue about, and am grateful for being exposed to.
