- 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.”

Of course this is their valentine's video 🤣
Indeed! Love is in the air! And soil!

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!
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 RUclips!
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 💀
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 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 was waiting for a "would you still love me if I was a worm?" joke 😂
🤣
Yes we Still Love You todays dont wait that time when you convert into Worm ❤😂😅😊 i Love You.
Okay, this was a weird one! 🤣🤣🤣 But just couldn’t take my eyes off it! Great video as always!
Glad you enjoyed it Joey!
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 🍷🗿
🎯
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!
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: ruclips.net/video/O-0SFWPLaII/видео.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.
Perfect for St Valentine's 💀
Totally!
VALENTINE IS TOTALLY HARAM !
What the heck is st valentines
💀
St. Valentine's 💀💀💀
Earthworm took valentine night to next level.
This is cool and all, but can we just start fishing?
So those are worm egg...
Thank you for showing it,i never seen it in my life :D
I didn't know that worms had such beautifully iridescent skin, amazing video as always!!
nature explored....
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 😂
Earthworms are amazing creatures. They do so much good for the earth.
This worm is getting way more action than me 🤣
The way they reproduce absolutely blew my mind!
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
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 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🙏
That was terrifying
Every date is a blind date for earthworms
I love the
- video quality
-narrator
-soothing voice
and last but not least the Animalssss !
Thanks to all of the DeepLook member !
u guys are amazing !
Lovee from malaysiaa xoxo
you mentioned the narrator twice, but well deserved
@@keeparguing611 oh apologies 😅 i am not very good in english .
Do you have a crush on the narrator?
Aww…partners in grime ❤️❤️❤️❤️
Doh! Why didn't we think of that??
Your videos are so knowledgeable, love them!
Glad you like them Preet! And thanks for answering our GIF Challenge! ruclips.net/user/postUgkxGdIZNGGW884hyqJmDh4zsQgyMuTaLTJB
This is adorable.
Love these videos so much. Thank you!
Glad you like them Patrick!
I just love worms and gotta admire how much essential they are for us in this Earth !
I think I'll show this to my valentine to get her in the mood 😏
Well, science can be very exciting!
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 🙏🏼
My biology teacher teached us this long time ago. I was called to answer how earthworm produce children and I said "they hugged together. Sorta". And teacher said:
*"yeah. But what kind of hug"*
Today's video was full of love n beauty. Got to know about farmer's friend
This was unexpectedly fascinating
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!
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
Whimsical music aside, this is both fascinating and horrifing, visually. Pretty cool.
I absolutely love this channel. Every time I get the chance, I look for a video that I haven’t watched yet or that are new! I have always been a bug and animal person but one thing I’ve never looked into, is how worms reproduce…. I’m so fascinated with Deep Look. Thank you for sharing these always awesome videos.
Man I don't think I would ever be in a situation where I needed to hear all this. It's very weird, but I never worms had this much going on. Pretty cool animals.
I used to grab earthworms and put them in my mother's plant pots when i was young. Such fascinating little creatures.
Earthworms! We see them so often but we don’t really know them. Thanks for the vid!
Thanks for watching!
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 😂😂😂
From the time I started to watch this channel to now. It has consistently been fascinating!!! Keep it up guys
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. ;-> 💓
You are awesome DEEP LOOK. You get clean and clear footage of any weird microscopic concept.
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!!
FAVORITE CHANNEL UPLOADED TODAY AAA WHAT A TIME TO BE ALIVE
WOOOO HOOOOOOOO
I’m currently obsessed with earthworms! They make me sentimental… thank you for this video!
You are so welcome!
Same, they were my one true passion when I was small
This is a good one! You should have your own Netflix series about worms!! XD
Laura's narration makes watching anything 😱, possible. 👍
informative yet so calming , the content is amazing
Glad you think so!
This is just weird. As usual, great job guys!
Glad you think so!
I wonder how this channel is not that famous yet
I really really love these videos
❤️
I love these little theys. They help me in the garden and I try to hide them from the birds.
I never thought about worm love. The sexy time slime sweater is not what I expected, and yet I am not surprised. Fascinating stuff!
Kudos to deep look. They make this seem romantic 😂. Deep look diving into deep love.
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 never knew you could make worms look like they have such complicated minds. Fascinating…
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 😬😬😬
I once saw worms in my backyard being cuddly with each other, I couldn't help but smile as I run into the kitchen to grab a salt, I shower them with salt to add to the romantic scene. It seems they like it as they squirm even more on each others embrace.
Oh... thats just cursed.
Respons to my nice comment 🍷🗿.
Amazing photography and an equally fantastic narrator to go with it!!!! Great video...
Thank you, we really enjoy making these. 🪱🪱🪱
Thankyou so much for this fascinating and educating video! 💕
I will always looking forward for your next project videos ☺️
Thanks for giving me the info ......🙂
Any time!
This brings back that short I watched from Isabella Rosselini about earthworm reproduction (featured on Sundance I believe). She used a giant worm costume to illustrate it, but it's interesting to see actual footage after all these years xD
That was awesome, never saw worms in this kind of light so the change was welcome
Thanks to all of the Deep Look member !
u guys are amazing !
take Love from Bangladesh
The way they lay their eggs is so unique omg
These creatures definitely are underrated!
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 used to be disgusted with worms when I was a kid. But my mother would hold them when she does her favorite pass time... gardening. Now that I know the essence of earth worms for a healthy soil, I kinda appreciate them but still can't hold them directly unless I wear a gloves
the worms do get a bit quirky at night
True. They prefer to stay in the dark, under the leaves.
I just recently started a worm farm! I love these little guys, they’re so good for the environment and so interesting! They’re also adorable in their own way.
Excellent!
I adore your words. They added many layers of comfort to this otherwise scary video
These videos are the bomb. 🎉
I have question. Is the cocoon a single egg or bunch of egg? I loved this episode because of the great details in videography. Love from india
Hello SUSpikachu. I produced this episode of Deep Look. The types of earthworms we filmed, Eisenia and Lumbricus, make many cocoons, each with one or two earthworms growing inside. Thanks for watching! -Gabriela
@@gabrielaquiros1966 thanks Gabriela. So you are the producer of this episode! That's amazing. Looking forward to more amazing content
I studied about this in middle school but it's so much more engaging watching a video on it than reading about it in a bland textbook.
DEEP LOOK , never disappoints us in their narrations
As a non-binary bisexual, i relate to earthworm

WOW
This is such a great educational video to be honest. Everything is so well described and most important part is that every single part of earthworm is so clearly shown, this is such a high quality details. Trust me even when we dissect the earthworm, we couldn't see every details of the earthworm as good as in this video. The fact that, even those setae are so clearly seen and even the process of it eating is so clearly shown, that is something you couldnt see easily if you were to observe it by holding an earthworm in hand. This kind of video is so important for students. But sadly schools only focus on the words written on textbook.
Amazing cinematography and science! Brilliant!
That's pretty hot.
Their iridescent skins are just... mindblowing. Thank you for showing us, Deep Look!
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
When being clingy is an advantage. Fascinating! 🤣
This is some really good footage.
Absolutely beautiful! I am new here, and I am subscribing right now!
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 thought it'd be rlly interestibg if yall did one on Robber Flies!! I think they're rather underrated!
When I go fishing, sometimes I'll use a hypodermic needle to blow air into them so they float
Lol wow thanks 😂 I've always wondered about everything on here , I love to fish an caught many worms hooked together, I always wondered how they had babies , awesome
Wow I didn't know that is how that clitellum works. That is ferkin' mind-blowing!
this is disgustingly intriguing
"Hey, im female idk if we can mate."
"Its fine, i am aswell!"
💀
It's just a worm, but Nature is awesome, strange and beautiful.
Lol, the first time I saw that in my bin, I thought one worm was choking the other one and I separated them.
I love watching deep look on Saturday nights 🥰
Wow their rainbow skin is so beautiful! 🌈 ✨
