a little more bespoke tailoring would make the host look soooooo much better! Shoulder pads to balance the midsection and a little structure would make him look much more spiffy!
"Cannot escape from the star". What is the escape velocity of such a worm star? And if successful, does the escapee's entire behind get torn off, leaving them with a wormhole?
Bro...just a perfect response. Kudos.
"Jerry, that's not a wormhole."

It's nice to know that scientists made literal "Snakes on a Plane" an actual scientific study
I am perplexed and intrigued by these scientific snakes on this scientific plane.
Sadly, this disproves that 'Snakes on a Plane' is plausible - Another movie that I can't watch.
If only Samuel L Jackson knew to put the plane in a nose dive. But somehow Cobra Starship knew about this trick.
I can picture a grad student getting on that plane thinking, "I just wanted to work with animals."

I think the snakes are trying to rest on themselves like they would a branch or an arm. They're used to their bodies always being in contact with something and it's their natural instinct to wrap onto a branch
That's what I thought too, it seems natural for them to need something in contact with their bellies so they can move.
When youtube commenters have better ideas than researchers.
Snakes are so damn adorable.
There have been observations of murena eels tying themselves into dynamic knots without anything near them.
Leading theory is that they do that to literally scratch themselves and get something off their skin.
I imagine it feels nice to do that too, like stretching
As a snake owner/ lover, inclusion disease terrifies me. The thought of snakes on a plane flying irregularly breaks my heart man 😭 I hope they’re just scared and hugging themselves and not anything more harmful 🥺
On the other hand: Evidence that some snakes may like to be held by humans. Not making definitive claims here, but if they see you as a branch safe enough to rest in or explore, that is also warm and cozy, it makes me feel nice in my sentimental human heart.
Look on the bright side. Check my post. ⬆
Poor little danger noodles!
Aww, snake stimming for comfort = ♥️
When you're swimming in the creek and an eel bites your cheek, that's a moray!
When food's in a tight spot and it ties into a knot, that's a Moray!
When a fish bites your heel and it looks like an eel, that's a moray!
When you swim in the sea and an eel bites your knee, that's a moray!
you guys & gals are cracking me up 😂
I recently bought a plush eel and tying it loosely around my neck made an excellent travel pillow.
Also one of my ball pythons just shed and left his shed in a knot, which i assume he used to assist in the shedding process.
Thanks - that´s interesting (about the ball python, I mean).
I think that might be the only time I’ll ever say awww about snakes. I love the idea of them tying themselves in knots in comfort, like a hug 😊❤️
snakes always illicit an ‘awwh’ from me. they’re adorable noodles.
danger noodles? nah, just comfy shoelaces
I have 3 ‘pet’ pythons. They each enjoy time out of their individual homes just to have snuggle time with mum (me).
They will wrap themselves around my arm without any constriction or curl up on my shoulder and go into a cozy sleep mode; clearly relaxing for them but also for me!

I REAALLY Love the Notion that snakes tie themselves in knots as a way of giving themselves hugs
S.L.Jackson: "I'm tired of these motherf**ing snakes on this motherf**ing plane!"
Snek on plane in microgravity: "I'm knot..."
I had just watched a TH-cam short about earthworms being tied together at the end this morning. Perfectly timed video. Great content as always!
Snakes tying themselves up as a soothing mechanism is actually really adorable
1:50 I want my notification sound to be this clip of Hank saying, "colonizing the rectum!"
This is a little oddly specific, but im here for it
Sea snakes also tie themselves into knots to clean themselves of grime and parasites as well. Something to think about as a more naturally seen event with snakes
"Knot up or shut up."
Kudos to the writer who came up with that. I love stupid puns, and that was a really funny stupid pun! 😂
Always a good time to give the Hodgkin lab in Oxford a shoutout! Brilliant C. elegans research, I remember speaking with the people who first discovered worm stars.
What if the snakes feel like they're falling and the knot is actually a way to cushion a fall?
Wouldn’t more surface area be better to fall on and not less? 🤔
My guess was that weightlessness feels a lot like falling and instinctually, it would make sense to form a shape that would most likely get caught on something to avoid that full-force landing. Loops might catch on stuff when you're falling off a cliff.
@@Miller73 While this is correct, it depends. Ideally you want all your vital body parts to be cushioned by your non vitals. It could be a survival mechanism that increases the rate of survival by ensuring the majority of the damage go to areas with better self healing capability.
@@DemonXeron Great point 👍
it's a valid possibility maybe arboreal snakes could do it,
yet, it's good to point out from all that I know snakes overall speaking aren't very smart, but reptiles overall can get very stressed, snakes have different reactions and reflexes to environmental changes.
...
it's still fun to think that in a sense when we get scared some of us curl into a ball or try to hide under our blankets as children.
you can give it a proper evolutional explanation but it still doesn't discard the fact that maybe it's not just one factor playing out here. The hug hypothesis still is my personal favorite😆
it makes me think that maybe... since now we know they do this, it might not be worth it to put the snakes in an airplane (again) just for the sake of understanding why they do it, poor danger noodles.
Some very interesting points on why there are knots
I have a deep phobia of eels, and I want to learn about them without seeing pictures. I just can’t get over the fear, and honestly I have accepted it. Cool video, I’m proud of myself for not crying at the thumbnail💀
i'm proud of you too! i do hope the phobia eases up one day
Lol did something happen to make you fear and then?
@@phelan8385 Very few such phobias are results of real bad experiences. Like, the percentage of people with a dog phobia who have been bitten is not meaningfully higher than in the non-phobic population. It´s weird.
Good job! Keep learning (and maybe looking at little pictures?), it can really help!
Good job. I'm similarly perturbed by eels but can handle photos...I avoid entering bodies of water, and my fear is really about seeing them "in the wild." What you've described, phobia wise, is how I feel about bats. Horrifying to me...and I HAVE had to encounter them irl. 🤢
Maybe the snake knots are a mix of 1 and 3: The snakes get confused about where everything is, so they deliberately try to "pull themselves together" so they don't fly all over the place
There’s a book by Terry Pratchett called the amazing Maurice and his Educated Rodents. I definitely see that some of it was pretty creepy with the rat king. Great book though. 😊
I had a pun for this, but it's knot funny.
I had a joke about a knot, but it was square.
Another reason for the snakes to tie themselves in knots is that it may be a protective mechanism for falling. Being in a knot will allow them to roll down a surface better or prevent whiplash (which can break their spine) when they hit. Also, it may be a response to trying to get out of a bird's talons by using the knot to push themselves out.
"I'm tired of these knot-tying snakes on this parabolic plane!"
If there’s an 80% chance of death from the worms and they call it a “star” scientists REALLY missed the opportunity to call it a Death Star
This is too perfect.
When nerds aren’t nerdy enough. 😂
Oh Rat Kings are absolutely real, I found one in the corner of my dad's abandoned workshop when he said I could clean it up and sell all his tools. I honestly thought it was most likely impossible, until I actively saw this nest of about 7 to 10 almost completely mummified rats of varying sizes that I tried to pull apart to count until I realised their tails were tied in knots. Seems unlikely, but it is apparently very possible!
That pythons like be held has been (nearly) scientifically proven? My anecdotal evidence of my beloved ball python Lucia loving to cuddle with me feels so vindicated!
Oh 💯! My bro has 4 children's pythons and they all love to be held/handled, one loves to half wrap around my neck and rest her head on my shoulder whilst I go about my day.
I looooove the “ big hug “ theory ~ makes sense 🤗
Thank you for providing footage for this one! My brain legit could not understand this concept.
"Bends, twists, contact and insertion" is basically my playlist in the boudoir. Hey-o
There is species that exhibist strange knots tying rituals that some specimen enjoy. Rather than using their bodies to bend and twist, they use ropes to tie either oneself, or another specimen. Tying can be limbs to limbs or limbs to objects. Scientists speculate that they do it because of sexual arousal.
This is true. And, put that way, really weird.
Snakes hugging themselves for a calming effect would be cute, yes, but if that were the case, they ought to show the same behavior in other stressful situations, which they apparently don't, so that suggested explanation sounds bogus to me.
Stress responses can definitely be conditional, so not using it in a different situation doesn't mean much. In other situations, they may have other prefered alternatives that just aren't on the table when you're floating weightlessly away from the table...
I’m knot impressed!
*No kink shaming!*
When a eel ties a knot so he eats what he's caught that's a Moray
What if they tie themselves to brace for impact? They might know the feeling of wheightlessness from falling from trees and tying themselves seems like a good strategy to reduce damage upon landing...I guess we have to trow some snakes to test that hypothesis.
You monster. Let's do it.
How fast do the snakes tie up?
Is protection from falling a possibility?
Holy Lovecraftian Eldritch Horror, Batman!
The eel sounds like it would do great in a sports climbing Lead World Cup. Any cracks or crimps, proficient.
Snakes got suddenly a lot cuter😂😂😂
3:13 has me singing, "That's a moray!"
Those Hagfish must get bad regret like "man, there was a way more efficient knot I could've done". Call that post-knot clarity.
even hagfish experience the paradox of choice
I can't believe you didn't call that mess of C. elegans a death star!
4:07 I could watch that move for days. I have to say that was cool
Never thought I would hear Hank of all people say "knot up or shut up".
Ball pythons are champions at making a knot of their entire bodies. Messy knots, sure, but they're very good at holding the position!
I wasn't expecting Snakes On A Plane to make an appearance, but here we are!
When I saw them eels and hagfish getting all tied up, I said to myself, "Oh, hell no!".
a beautiful sunflower of worm death
the bacteria get a steady source of nutrients and the worms get dead
pulling an eel and it's meal
This is Scishow's most poetic video
The snakes are just curling up into a ball to make themselves a smaller target for Samuel Jackson
Babe! Next big mini-game dropped!! Tying knots to escape predators!!
Snakes need hugs, too!
I was sooooper confused trying to understand how The Nutcracker had anything to do with this 😂😂😂
Quantum entanglement. It's just life.
This was.... knot exactly what I was really expecting. And yes, I suspect someone else already used this pun, but I'm knot gonna take time to look. Knot enough sleep, knot enough coffee, knot enough energy to care. And I'll wager knot all of the rest of those were ones used by others, so at least one was new. If knot, then ... damn the bad luck. I'm just a knotty old lady.
Snake self soothing 😊
I need hugging super power like the snake
@8:35 *My favorite reason is* ... developmentally-speaking makes the most sense, same way traumatized humans curl into a fetal position? The unconscious primitive brain stem "remembers" what it felt like inside its (suspended weightless state) egg/womb?
i first found out about rat kings yesterday! 😮
So which would win a knot-tying competition - hagfish, snake or boy scout?
Well hello oxo i was re-watching sci-show videos and what do you know! a new one just out of nowhere. Awesome =x=
Cool thanks
3:12
Wait a minute, that eel...
That pose... Do I know where it's from?
I guess knot.
All these animals tying the knot and yet I can't even get a girlfriend.
Give your buddy a bud lite and you will 😀
U good bro
@@definitelynotwalter i don't think bro is good
First most important step is to stop "trying to get a girlfriend" for its own sake. Just meet people without having an ulterior motive
Have you considered tying yourself into a knot? It could improve your hugging capabilities maybe
When I was a kid I went fishing and caught this massive eel. It was easily 4 foot long. As I pulled it up it started writhing around and tying itself in knots. I finally got it onto the wharf and didn’t know what to do, so I started crying and then the hook fell out so I just threw it back in the water lol.
I feel like the snakes on the plane might be disorientation. Like humans! I see a lot of people that goes on those rides tends to throw their limbs around and move like a cat trying to hold onto something. lol
C. Elegans are sea elegant
didn’t know knots were this common in nature
Hank is the best
I've seen a video with squirrels as well, pretty dangerous for them indeed.
the snake theory is so cute hahaha
Maybe snakes tying themselves in knots in micro gravity is because it’s like they are falling and trying to create more surface area for drag to slow them down in free fall?
Whoever wrote this script deserves a raise!
Dogs do it all the time. You know what I'm taking about.
Eels are like monks of the sea.
Love from the USA
rat kings are real, although extremely rare, someone caught one on video before and I believe its the only one been captured on video
The real “Snakes on a plane”!
I choose to think the snakes just want comfort. I want to tie myself in a knot when I'm distressed
Danger noodle is best noodle.
I wonder if the snake knot is a behavior to protect against falling out of trees/off cliffs. If they instinctively knot up in freefall it may help the survivability of the landing.
2:11 scientist call them sunflower, I call them the ancient one..
When I'm fishing and catch an eel, once out of the water it starts making knots, one after another. I was always wondering why and thought that they might have evolved to do so because by making knots, sometimes they can break the line and free themselves.
Could that be something or it's them just doing their last attempt of not getting eaten?
When I heard snakes and knots I thought you were going to talk about constrictors.
02:43min (among others) death star for worms. pun intended.
Ratkings are real. The Dutch biologist and author Maarten ‘t Hart wrote a book about rats, and dedicated a whole chapter to phenomena.
And it’s a sad thing
Huh, interesting, I'm surprised there isn't a theory for the snake ball that the snakes feel like they are falling, so they curl up in a ball to protect themselves from hitting the ground at high speeds.
I guess they would have to test dropping snakes from high places, but that might be unethical because it might kill the snakes. I also wonder if they tried this "snakes on a plane" with tree snakes, who often fall from trees anyway, or jump from one tree to another. Weightlessness probably isn't so scary for them.
They are running which way
Snakes on a plane huh... I'm sure there's a quote for that somewhere...
Nuts for knots❤
Is this related to the phenomenon of cord headsets always ending up in a knot after putting it in a pocket?
Asking for a friend.
No, thats entropy.
I can’t vouch for rat kings but, I know that mice kings do. I once kept mice and one day came in to find 10 or knotted together and deceased.
I've actually done the hands on the butt to feel like sitting in a chair thing but i did it while floating in a pool.
the eels seem to just be trying to curl up their tails?
and the snakes are probably just seeking sensory input on their undersides.
5:30 My garlic butter suddenly got significantly less appetizing ...
