- Earthworms know a thing or two about romance. They cozy up with a mate inside tubes of slime, then follow a series of intricate steps to make cocoons full of baby worms.

You can tell an earthworm is ready to mate once it has grown a fleshy patch called a clitellum.
When it sidles up to another earthworm, their bodies point in opposite directions, and the worms surround each other with tubes of slime exuded from their skin.
The earthworms embrace by using flaps on their clitella, and exchange sperm that travels outside their bodies. As they snuggle, the sperm flows into internal storage sacs.
After mating, an earthworm produces a sheath with its clitellum that it shimmies down its body. The protein-rich ring moves over tiny holes, where it gathers eggs and some of the collected sperm. Then, the ring slips off the worm to become a cocoon with one or more developing earthworms inside.
--- How do earthworms help the soil?
Earthworms eat tiny bits of degraded plants, which have bacteria and fungi growing on them. This organic matter might be in the soil or in leaf litter on the surface. Some earthworms eat manure. When they poop out the remains, earthworms make nutrients like nitrogen available for plants to grow.
And the earthworms that live underground spread around their nutritious poop, known as castings.
“Subsoil comes up to the top, topsoil goes down towards the middle or bottom,” said Sam James, who studies earthworms at the University of Iowa. “And you can see the difference in colors of these two layers of soil.”
Earthworms also create channels in the soil through which air and water can move, he added.
--- What is worm composting?
Earthworms such as the species Eisenia fetida can be kept in a bin and fed certain types of food scraps. Using earthworms to dispose of leftovers in this way is also known as vermicomposting.
--- Can earthworms reproduce without sex?
Yes. Some earthworms can reproduce on their own, through a process called parthenogenesis. These earthworms are all mothers - they don’t make sperm, only eggs. Their offspring develop from eggs that divide into identical copies.
“They just clone themselves,” James said. “So what it means is a single individual can start a new population.”

Worms are so weird yet fascinating
Agree! And so varied, too.
just like women ☕
@@KQEDDeepLook Perhaps you could contribute to a burgeoning Worm Week movement with some other cool content creators here on TH-cam!
The 7 Days of Science guys seem to be leading the charge currently.
So many different groups of creatures get lumped in under the descriptor "Worm": Annelids; PlatyHelminthes;
Nematodes; & Polychaetes, just to name a few...
Love your vids!!
@@getcaughtin4klol752 dude just admitted he has no game
@@getcaughtin4klol752 bro didn’t find his Valentines girlfriend 💀
Of course this is their valentine's video 🤣
Indeed! Love is in the air! And soil!
@@KQEDDeepLook 💀
@@KQEDDeepLook 🤨📸
@@KQEDDeepLook pfft
Yow hahaha
This is taking the saying "would you love me even if I were a worm" to the next level.
YES!! 🤩🤩🤩
can a worm become a worm again
Never really gave the thought that worms mate. I just kinda assumed they spawned outta nowhere
@@melatonin1371 I thought they made more of themselves by being broken in half. Actually I didn’t think that, but I know some living things can do that, I just can’t think of any. Other then starfish, which I just thought 💭 of. Love ❤️ from Australia 🇦🇺
@@kerrynicholls6683flatworms!
I have had worms for more than 10 years at home in various places: balcony, kitchen and even by my work desk. I have encountered all kinds of worm mating behavior, even self mating. But presenting such simplistic animals with this much detail and clarity even made me curious about their anatomy. Wonderful camera angles and shooting as always, and such demonstrative video!
Thank you Cagri!
You need to get better hobbies or fill your time Jesus it sounds like you have absolutely nothing to do lol
I don't get why there's an expert in everything expert in elevator experts in toilet
Excuse me....selff MATING?? .
@@neonraindrop8357 That sounds like something
We shouldn’t talk about
I am so confused. I am so revolted yet fascinated. Only Deep Look can evoke these two emotions in equal measure every single time.
Love is complicated!
Why would you be revolted?
Exactly. So strange, but so satisfying for your curiousity. 👌
I completely agree with your statement! lol
@@Guydebuteuse your eyeballs
I feel like we shouldn’t be watching this… those poor worms probably have no idea they were filmed lol
they are probably gonna get posted on a dirty website for worms
Even if they knew, I bet they'd feel no shame 😂
I can't emphasize how surreal it is to see earthworms in such great detail, I used to look at earthworms all the time as a kid and seeing something so familiar in this light feels like putting on glasses for the first time, haha! Amazing work on these shots!
It's not the size of your worm, it's how you wiggle it.
I'll see myself out.
🤣🤣🤣
reminds me of this site called staggering beauty (it's quite literally a giant worm that wiggles with your mouse, epilepsy warning tho)
underrated comment xD
Bruh 🍷🗿

So I have a massive phobia of worms since childhood, especially earthworms (leeches are an exception for some weaird reason I don't know, they're kind of wholesome in a way) yet this topic just felt so interesting that I somehow forced myself to click and watched most of it.
OK, I admit I spent most my times in the comments, but hey, not bad for a start. And the infos were actually super-interesting, as always, so keep up the good work, it was another amazing video.
Glad to hear you still fond it interesting, Alchemy. If you have not seen our episode on leeches, here you go: th-cam.com/video/O-0SFWPLaII/w-d-xo.html
That's funny, worms I have no problem with but leeches terrify me
@@christianshawyer7344 I know right, it makes no sense since leeches are just bloodsucking worms. But when I was 4 or 5, my dad told me they actually used them to heal tge sick so I always considered them sort of "good guys" as a kid.
But with worms its just a different story, no matter how useful and vital part of the ecosystem they are I just couldn't look past this sorr of elemental fear and disgust I felt
I just find it so funny how ‘farmer’s friends’ scare you but the blood sucking slimy one is a wholesome 😂
Same phobia here I understand.
The way they reproduce absolutely blew my mind!
I didn't know that worms had such beautifully iridescent skin, amazing video as always!!
nature explored....
i cant believe that i (17) learned how earthworms, such a common animal, reproduce on youtube instead of school
Thank you deep look
and greetings from germany
I've caught my worms getting it on multiple times. I just close the bin and put on some Marvin Gaye.
Very kind of you, Ijeoma. ;-> 💓
I can’t believe they didn’t teach this in school. I personally don’t like worms but I like learning new things about them. The way the video is presented in this video is also a real huge W, especially because I didn’t feel disgusted at all!! Thanks so much for this🙏
I always wanted to know how they mated, and I had no idea this would be the process or how they produced their eggs.
As a kid, Since Earthworms has that ring around them (the Clitellum), I thought Earthworms were the reason we got Ringworms on our skin 😂
I used to say they had a 🩹 bandaid on them 😂
This worm is getting way more action than me 🤣
Shut it
So technically, worms do the funny number.
Earthworms are amazing creatures. They do so much good for the earth.
Hence the name earth worm 😂
Lol, the first time I saw that in my bin, I thought one worm was choking the other one and I separated them.
Aww…partners in grime ❤️❤️❤️❤️
Doh! Why didn't we think of that??
This is cool and all, but can we just start fishing?
Gosh these videos are always so amazing!! The narration, the filming, all of it is just so wonderful! Thank you for this incredible content.
You are most welcome 🙏🏼
OMG, one of the biggest questions I had as a child has been answered, earthworms have bristles they use to anchor and it push against
I just love worms and gotta admire how much essential they are for us in this Earth !
I used to grab earthworms and put them in my mother's plant pots when i was young. Such fascinating little creatures.
My phobia was making me feel disgusted the whole time, but the video was so well made and it was so interesting I had to watched it. I feel itchy 😂😂😂
Once I dreamed that I was a worm - I was not a person in a worm body, I was the worm. I felt my worm nervous system interacting with the soil. It was dark. And then in the darkness I touched another worm, and my whole nervous system lit up. It was blissful
True story, be kind to all living things
I absolutely love earthworms. They are the only worms I feel no disgust for and love holding.
Same I've always been obsessed with them
🫣🫢😣...I mean... good for you guys because it's the total opposite here. I just can't stand all that wriggling.
@@fhenlizhao5406Same, they just freak me out 😬😬😬
As a worm farmer who had to learn about worms through years of handling and observation sistered with reading hard to stick with research papers, THIS is amazing! SO fun to watch and better shots than I was EVER able to see with my bare eyes and a magnifying glass! HUZZAH to the lil soil producers!!
Laura's narration makes watching anything 😱, possible. 👍
I never knew you could make worms look like they have such complicated minds. Fascinating…
You are awesome DEEP LOOK. You get clean and clear footage of any weird microscopic concept.
Every time go fishing you can now assume I’ll be thoroughly disturbed.
loved this one, thank you for not only helping me learn this but visually showing everything! sooo important!
This is just weird. As usual, great job guys!
Glad you think so!
Earthworms! We see them so often but we don’t really know them. Thanks for the vid!
Thanks for watching!
From the time I started to watch this channel to now. It has consistently been fascinating!!! Keep it up guys
I love worms and have always thought they were cute and funny. Thank you for the info. Life is amazing
informative yet so calming , the content is amazing
Glad you think so!
I can't quite tell if the cocoon has a lot of worms in it or just one. There are so many cocoons in the picture at 3:37 it leads me to think one worm per cocoon. Anyone?
Thanks Hank!
When I go fishing, sometimes I'll use a hypodermic needle to blow air into them so they float
These videos are the bomb. 🎉
got this video recommended on my feed again right after watching that Hank Green video
Thanks for giving me the info ......🙂
Any time!
That was terrifying
"Hey, im female idk if we can mate."
"Its fine, i am aswell!"
💀
Eerie, creepy, typical of Deep Look!
This would be one of the best footage for such an ordinary creature, but scarcely known its life! Well, well done! This is DL! Thanks!
I love the way that you are replying over comments.... 😍😍😍
Thanks Atul!
they do a good job cause they got so many animals to feed.
Their iridescent skins are just... mindblowing. Thank you for showing us, Deep Look!
This was kind of cute ngl
Better love story than "twilight"
Bruh even these worms have partner than me
Amazing photography and an equally fantastic narrator to go with it!!!! Great video...
Thank you, we really enjoy making these. 🪱🪱🪱
Hey Laura, you are the best!
So, we conclude, everyone including worms get more action than some of not all of us here :))
These creatures definitely are underrated!
beautiful video, the narration especially was wonderful!
Oh wow, that's incredibly fascinating! I've always wondered why they have that big "ring" on their bodies, but not in a thousand years would I have guessed its purpose
one of these actually tried to pull me underground when I was gardening i'm not even joking they're so strong. Well I was pulling it, but it resisted, they're almost impossible to pull out how am i weaker than a bird lol
I've always wondered how worms reproduce. I didn't think it was because they got cut in half and became two.
We actually have a video about a flatworm that can do that, called Planaria: th-cam.com/video/m12xsf5g3Bo/w-d-xo.html
I really really like this ladies voice! Natural narrator, no pun intended
That’s Laura Klivans, our host and co-writer. :-)
I've studied about them last year in 11th.
Worms get more actions than I'll ever get in my life 😭😭😭😭
Wow their rainbow skin is so beautiful! 🌈 ✨
The sheath becomes a egg for the baby worms just blew my mind! I cannot believe that I was never taught that in school.
I remember when I was 8 years old, I used to go out in the rain and look for earthworms, I wasn't scared of them but always thought that they bite
Absolutely beautiful! I am new here, and I am subscribing right now!
I actually just saw a worm mating without knowing they where since i was afraid of one and i did not notice them getting too close to my slipper I actually kicked em accidentally 💀
Great video. Warms are very Weird. If one somehow gets cut in half they become two warms. Never understood that, but this is fascinating.
I never thought much about earthworms but thank you for teaching me what that weird ring around their body was for.
It was fascinating for us to learn about this as well- one of the joys of working on this project is that we can learn new things!
i am never been so thoroughly confused and so fascinated by a creature
It's 2:11am, never knew worms did it like that. Neat.
Bodies pointing in opposite directions, nice
"such a luscious... lip?" 💀1:35
I always wondered how plumbuses got made.
I thought it'd be rlly interestibg if yall did one on Robber Flies!! I think they're rather underrated!
Even worms get to mate.
Slipping off an egg like a weird nightgown is fascinating
Most important worms for healthy soil
It's unnecessarily trivial and fascinating.
Worms are cool but at the same time, I don't like them. I don't kill them, I just leave them alone. They don't want me to touch them and I don't want to touch them either.😅 They are truly interesting but I prefer to read or learn trough internet. Preferably reading.
The lady's voice is strangely relaxing
I adore your words. They added many layers of comfort to this otherwise scary video
I was wondering why they had that ring, it's an engagement ring!
I've eyes wanted to see a documentary about it
Idea: grow a blob slime mold and put it up against a death cap.
Even worms are jealous 😂😂😂😂
Earthworms are weird yet have a great importance on the ecosystem
love worms!(at least the beneficial ones)
I never knew what a earthworm egg looked like until now
I love watching deep look on Saturday nights 🥰
Wish they had more thumbs up.. amazing stuff
My biology teacher played this in class💀
Amazing cinematography and science! Brilliant!
Throughly captivating!
Today I did not drive my car, it was raining all night and i come out to worms all over the ground and i didn’t want to run them over
This is awesome! And fascinating 😮
I love Seth Samuel's music here. Do I detect a "Bride of Frankenstein" influence?
