I met a young jumping spider in my garage during the pandemic and decided to adopt him. Having him as a pet changed the way I think about spiders. He was so smart, and had such a cool personality. They do more than hunt like a cat, they act like cats in a lot of other ways as well. No surprise I'm also a cat lover. Too bad they only live a couple of years. RIP Seven, you were a real one.
I absolutely agree with the cat thing you said. Consider getting a female tarantula as a pet, dude. They can live up to 20 years or longer, and they are absolutely adorable
I had one that lived in and around my nightstand during the same period. I gladly shared the space with her. I used to talk to her and she's look at me and wave her little pedipalps around to talk back - or to let me know to leave her alone or she'd bite. Who knows which. She wasn't afraid of me, though, and she would come hang out with me when I was sitting on the bed. I had a habit of rolling over and slapping the back of my hand during sleep on the nightstand, though. One night I guess I scared her and she bit me. They are tiny but holy shit that venom messed my hand up. Swollen, green puss and a tiny necrotic plug of flesh eventually came out. She moved out from the nightstand but a few weeks later on I found her at the bottom of the stairs. I knew it was her because of a distinctive mark on her legs and she wasn't quite as trustful of me. I guess I really did scare her that night. I caught her in a cup and let her outside in an oak tree full of aphids. A few months later I saw here on the tree fat and happy and we were pals again.
This is too cute. I lived on a boat that got really cold at night and if I woke in the night the spiders would be dangling just above me to get the warmth, this experience has now been made even more adorable.
I like the “running drills” explanation of dreaming, at least from the bottom-up evolutionary perspective. It makes sense that if an organ evolved to interpret transduced sensory signals into a unified model of the exterior world, that if that organ somehow gained the ability to simulate an entire fictional environment, that it would be massively advantageous for that organ to test trying scenarios in those simulated environments during that animal’s safest rest period.
I'm a fellow zoologist and animal lover and I'm blown away by this research! This discovery opens up so many roads towards knowledge and compassion! :D
Man, I love jumping spiders, they're so cute and friendly. The cat comparison is pretty accurate. I had a wild jumping spider friend that would regularly come check on me for a couple of years, with a frequency ranging from multiple times a day to once every few days. It's a shame they're generally too small to safely pet, unlike bees, but in my experience it's not too difficult to get them used to hanging out on your hand or whatever.
I wonder if spiders have flying dreams, too?!? I've never thought about spiders or any bugs sleeping or dreaming, but as soon as she started talking about seeing them dangling and twitching, my first thought was "Well, of course they do!" I would love to see a comic strip about spiders philosophizing over what their dreams meant! 🤣
Many spiders can actually fly by using a strand of silk - it's called ballooning, most commonly used by baby spiders so they can find their own place to live. I think it's possible they could dream about that, too
I currently have a small jumping spider who was at first very cautious around the large flies I was catching him. Now he’s confident and quickly catches them. It certainly felt like he learned how to hunt them.
I handled my jumping spider a lot, like for hours a day, and after a while he got so used to me that he didn't want to be off me. If I set him on a table or something, he'd run straight back to me and jump on my hand. He was obsessed with hanging out on my nose, but it tickled soo bad! LOL Such cool pets!
This is fascinating. I remember reading a book where the author made the point that, because sleeping is so perilous to the sleeper, if evolution could have found a way around sleep, it wouldn't exist. And yet sleep seems to be universal. Now, maybe if a creature has a nervous system, it dreams?
In humans, while in deep sleep our cerebral spinal fluid is flushed of toxins and the most healing/maintenance occurs. REM helps consolidate memories, so if an animal has the capacity to learn from past experiences, it most likely will experience REM.
For all you bookworms out there who are interested in spiders and in particular the Portia jumping spider, I can recommend “Children of Time” by Adrian Tchaikovsky. It's a science fiction novel in which a genetically engineered virus is released on a new world to speed up the evolution of a group of apes so that they can serve as laborers for the human settlers who would arrive later. But something goes wrong, and instead its spiders and other arthropods that rapidly evolve and grow larger. Large parts of the book are very cleverly written from the perspective of the now intelligent Portia spiders.
We find the jumping spiders around our house are so lovely and intelligent, we are enchanted by their personalities. We also have orb weavers and plump black widows, all fascinating spiders to observe. This was such a wonderful insight into the jumpers, I look forward to seeing how this research unfolds and what it uncovers.
Parrots "dream" too. I have 2 free roamingparrots, who sleep on me in the night. Very often, they make sounds without being awake and sometimes they look like having even nightmares, they scream and move, but I have to wake them up, like you do with children having bad dreams.
@@TV-xm4ps With some effort/persistence and adjustment you can lucid dream if you choose to, also not far off in the future you'll have a headset that induces lucid dreaming(tACS is the one of the tools). This research paper "Transcranial Alternating Current Stimulation (tACS) for Major Depressive Disorder", imagine the level of problem solving we can do in a infinitely creative platform like our dreams or it can be used for other horrendous things as well.
@@dherosoenno...now calm down. It is true she is bothering them. They didn't sign a consent form agreeing to living in glass viles or being blasted by bee and wasp wings beating. We can all imagine that being bothersome. It doesn't mean her research isn't very cool.
I used to keep a P. Audax by me and would notice her watching my monitor as I watched tv shows and what not, which isn't too important and coincidental most likely lol. But, she'd dream a lot (fang movements etc.) despite me rationing her food schedules. I also had a T. Helluo whom would curl her front legs into herself as she slept. Her fangs would then widen out, as if she was drooling (mouth open and all). So much more interesting things about spiders that we still don't understand and it's so fun to observe.
I love the children of time reference with the naming of the spider! Tchaikovskys work is so clever! Great work, I’m excited to see more!!! Here’s hoping Portia is the inheritor of Earth and the ‘human’ race!
Pretty sure you got it backwards. Portia is a species of spider, not a specific name. Based on my brief wiki search, the book is based on genetically modified Portia spiders. So the author choose this group for the book. Probably because they're the smartest of the jumpers, and probably spiders as a whole.
@@user-bt2lx4gy7hI think that's what they meant. It is made clear in the book that "Portia" the inherited name of the, queen? I guess of the matriarchal spiders is just reference to their species.
when I was young in the 70's I was told by my dads MIT friend that the jumping spiders are one of the only creatures that can make out the craters on the moon ..
I'm so confused by this comment lol are you trying to say she was punishing/torturing these spiders xD wtf do you think behavioural animal psychologists do except for watch animals lol yall need to go out more, the plight of the jumping spiders will not be forgotten hahaha
@@bobroberts8264 No, I'm not talking about her. Let me explain exactly what I meant. I'm talking about the entire history of sleep science. What do we KNOW about sleep? We only KNOW that if one day, we start doing something that makes us not need sleep ever in our lives (and we forget what sleep is), there will still be "the other" people, who sleep every night, and they can be tortured by sleep deprivation. So when we (the young people) accidentally go too hard on them, our elders should be able to reprimand us because of the research we've done on sleep in the past. We partly do science to prepare for the future, rather than to invent the future. And it helps diplomacy.
If a spider can dream, so can it be possible if all animals. Perhaps the dream function is what unites us to our animal families. And thus we are not so distant from one another after all
I've always had a special curiosity/suss-ness on spiders. They're different. Obviously they're arthropods, but they're way different to insects, and the differences between those two groups goes back to before they even left the oceans. Spiders have been on their own weird evolution path for a long, long time. That's why they're scary and strange creatures. Almost alien seeming
I was going to make a joke about spider's wet dreams, however, it strikes me that watching for a spidery erotic dream, moving parts of their anatomy that's only used at very specific times, might be better than misunderstanding the spasming legs as them running after prey or escaping from a predator.
I imagine that we might be able to someday track evidence of overnight changes in cognition and behavior as an indication of dreaming even without self-reporting being a necessity. You couldn't determine what the experience is like for them, but you might be able to see that the brain had been processing information at night by showing either electrical brain activity at night or changes in behavior that suggest an experience other than unconscious sleep has taken place, such as waking up responding to a stimulus that wasn't present externally.
I think it’s pretty sound to say that dogs dream for sure. Unless there’s some other completely unknown unrelated mechanism that causes them to bark and run in their sleep, it’s the logical conclusion. While it can’t be “proven” in any objective way, it makes sense to treat it as the most logical explanation for that behavior, and then I think this arachnid dream premise is not that far fetched.
I imagine this has something to do with the incredible amount of visual processing that these spiders engage in on a regular basis. Perhaps in a similar way that dreaming apparently helps to process and cement memory while the brain chemically recovers from the day, these spiders undergo similar neural stress from the volume of visual data they experience throughout the day. Jumping spiders occupy a similar niche to many small birds and cephalopods, experiencing the pressure of predation at the same time as they look for prey, which could produce situations that require more complex decision-making.
We've already found many many things of how intelligent tons of beings are including plants and fungi. It fills many who truly come to realize how absolutely not alone we are and how truly connected we are with this planet. Cruelty is just an artifice the universe is not that at all.
Not really. This doesn't show spiders (yes even portia), plants, and fungi are considerably intelligent at all. It only shows that adaptive behavior is an immensely basic thing not requiring very much complexity to evolve. It doesn't show those things are intelligent, it shows those benchmarks for intelligence are extremely faulty and mostly parroted by people with no real understanding of the hierarchy of intelligence. Usually by people who just sort of pick up learning about random animals and don't really have a broader evolutionary matrix to contextualize the species into.
@@artosbear Yes, that's why it's not about 'intelligence', that's a really abstract concept that applies to anything alive, be it individual or groups, and even to the machines 'we' make. The important part, when it comes to empathizing with something is whether or not they can suffer instead. Plants for example, there's no reason to think they can suffer, or really anything without at least some rudimentary form of a nervous system connecting to cluster of nerve cells that one might call either a ganglion or a brain, and then you gotta find out if they have receptors that respond to noxious stimuli and/or damage and connect to said nervous system, and how their behavior changes in response to such stimuli. And the closer something is to us evolutionarily, the less formal you have to be to figure these things out, because the resemblance becomes clear enough. Like for example with anything mammal you can tell right away since it resembles how one personally would respond. As in there's trembling, rapid convulsion if damaged area is touched, potentially screams, diminished activity etc. So the term "Cruelty" seems to make sense only if you apply it to entities that can suffer, instead of basing it on intelligence. Basing things on intelligence has been...quite the slippery slope historically, and it's easy to use it to rationalize being cruel.
i kind of doubt that no one has ever thought of this research question before; but you're the lucky winner who chose to focus their research resources on it. really interesting.
"I still can't belive that this has not been seen or documented before - cause no one ever looked." This sentence woefully describes human arrogance... we never looked close, because we never suspected something like dreaming arachnids could happen anyway.
It is also a very Eurocentric perspective. Other cultures, including my own, believe all beings contribute to the great dream of the world. So of course the spiders dream.
I've always found it arrogant and entirely baffling how many people think that animals don't think or have language. Like really, how could any species survive without being able think and communicate? It's just not possible.
Idk why but recently learning about this research has really changed my view of consciousness prob more than anything else ever has. Super excited to see where research goes from here.
Obviously spiders have higher nervous activity and they have dreams; and, surprisingly, incredibly enhancing influence of serotoninergic psychedelics on their brain activity and web weaving (just like humans) has been known for many decades, I wish this aspect also be researched thoroughly. Good job.
We, as humans, do not have exclusivity on dreams/sleep. Please don't sleep deprive spiders...bc then they WILL hate us right back...and I am far more afraid of them bc they have FAR more skill, talent and speed than we do!!!
I don’t know about spiders dream lives, but I do know pigs and cows dream, and the horror of how we treat them in those meat factory gulags, must make even sleep no escape for them.
Oh, I'm sure they dream, humans tend to think are special, but evidence has proven that we (animal, plant, planet or everything) are alike. All though I'm courious if dreams have an actually evolutionary advantage or if they are a byproduct Loved the vid Your job is awesome Take care of my little brothers and sisters 🕷️🕸️🕷️
I couldn't tell what stunns me more: the fact that she studies SPIDER SLEEP in the first place or the outcome of her research: That spiders obviously are having REM-SLEEP! 😯
You could watch for maybe twitching that looks like movement involved in hunting of different prey? In the spider that hunts other spiders, since they have multiple types of hunting strategies, they might exhibit multiple similar categories of twitching modalities during their sleep
We can know that humans dream without reports through for example the Tetris experiments which show humans dream of playing Tetris when they play Tetris all day because we can visualize it on fMRI. I recommend using infrared optical, scanning or two photon optical scanning on spiders and I have more experiments in mind , but a shortage of time. I can tell you 10 experiments that would show that spiders are dreaming and I think you have some in mind too. Don’t say something is impossible when it’s not. And don’t misunderstand skepticism of other minds because such a skepticism makes neuroscience impossible. Recall skepticism is a branch of philosophy and an important one, but once one gets on the boat with a natural ontological attitude (NOA), you have rejected the skepticism behind your sophomoric remark.
Somewhat unrelated, but I had a near death experience in Summer 2018 and got to meet the "maker" and talk to him about all the questions I had in life. I asked him if everything had consciousness or if sentient life was mixed in with bio-automatons. He replied: "Everything that dreams has a soul". Afterwards, when I came back here, the first thing I wondered was: "Do spiders dream?" Finally, years later, there is a video about the subject. How cool!
The bit about watching the eyes to see how they moved reminded me of this - All eyes have a common gene. That means that any creature with an eye has a common ancestor with any other creature with an eye. That means that if you see a creature that can see you then you are both looking at a distant cousin.
Speaking of sleep deprivation affecting behavior made me think of the book, The Fly. At some point he describes a spider's web being repeatedly destroyed by the author and how the rebuilt web begins to become more and more disorderly. I hate to recommend depriving spiders of sleep and then seeing how their webs fare when destroyed in comparison with spiders that get an undisturbed night's sleep. There's a mad, amoral scientist lurking in is all.
My theory is any creature that sleeps for long period of time needs to sleep, to keep their vital functions minimally working to almost a reflex level. This of course exclude hibernating animals who have evolved to turn half their body off.
Amazing video. I studied dream analysis for years to become an analytical psychologist. Sorry to hear of the departure of the progressive editor-in-chief of your journal.
much like humans do, dogs process memories of their day while dreaming. since we’re such a big part of their lives, if you see them dreaming, there’s a very good chance that they’re dreaming about *you.* 🐶😍
Very cool research. Wouldn't surprise me if they are dreaming, jumping spiders anyway. I bet they dream about jumping, getting the angle right, the right power-boost, nailing the landing, and probably about hunting and evading hunters too, processing their everyday experiences. ... So, if even jellyfish and spiders sleep, does that mean sleep evolved once, w-a-a-a-a-a-y back, or is a period of rest advantageous enough that it evolved independently in so many different animals? Almost every living thing on Earth is sentient to some degree. Could REM sleep be a reliable indicator of greater awareness? For that matter, plants sleep, do they dream or is it just lights out?
I think the bigger shock is seeing a large American jumping spider eating a giant Japanese jorogumo spider, because such a large prey would facilitate a larger predator, hence do we need to worry about hummingbirds and song birds eventually?
Thanks for the analysis! A bit off-topic, but I wanted to ask: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How should I go about transferring them to Binance?

Usually by people who just sort of pick up learning about random animals and don't really have a broader evolutionary matrix to contextualize the species into.
@@EyeSeeThruYou Tell me you've never watched a nature documentary without telling me.
@@artosbear Yes, that's why it's not about 'intelligence', that's a really abstract concept that applies to anything alive, be it individual or groups, and even to the machines 'we' make. The important part, when it comes to empathizing with something is whether or not they can suffer instead. Plants for example, there's no reason to think they can suffer, or really anything without at least some rudimentary form of a nervous system connecting to cluster of nerve cells that one might call either a ganglion or a brain, and then you gotta find out if they have receptors that respond to noxious stimuli and/or damage and connect to said nervous system, and how their behavior changes in response to such stimuli. And the closer something is to us evolutionarily, the less formal you have to be to figure these things out, because the resemblance becomes clear enough. Like for example with anything mammal you can tell right away since it resembles how one personally would respond. As in there's trembling, rapid convulsion if damaged area is touched, potentially screams, diminished activity etc. So the term "Cruelty" seems to make sense only if you apply it to entities that can suffer, instead of basing it on intelligence. Basing things on intelligence has been...quite the slippery slope historically, and it's easy to use it to rationalize being cruel.
i kind of doubt that no one has ever thought of this research question before; but you're the lucky winner who chose to focus their research resources on it. really interesting.
"I still can't belive that this has not been seen or documented before - cause no one ever looked." This sentence woefully describes human arrogance... we never looked close, because we never suspected something like dreaming arachnids could happen anyway.
It is also a very Eurocentric perspective. Other cultures, including my own, believe all beings contribute to the great dream of the world. So of course the spiders dream.
I've always found it arrogant and entirely baffling how many people think that animals don't think or have language.
Like really, how could any species survive without being able think and communicate? It's just not possible.
I always knew portia were special~
I've always been impressed by the western redback,P.johnsonii since i was a kid...the way they followed my finger left to right was neat!
Idk why but recently learning about this research has really changed my view of consciousness prob more than anything else ever has. Super excited to see where research goes from here.
Do spiders dream of electric ants?
Obviously spiders have higher nervous activity and they have dreams; and, surprisingly, incredibly enhancing influence of serotoninergic psychedelics on their brain activity and web weaving (just like humans) has been known for many decades, I wish this aspect also be researched thoroughly.
Good job.
Excellent video/information. Thank you!
I have been courious about spiders sleeping for a while, myself. I am happy to see that this is researched.
all these poor little dudes just like EH F OFF IM TRYIN TO SLEEP lel love me some jumpy boys
Meanwhile, jellyfish dream but they don't know that because they have no brains.
We, as humans, do not have exclusivity on dreams/sleep. Please don't sleep deprive spiders...bc then they WILL hate us right back...and I am far more afraid of them bc they have FAR more skill, talent and speed than we do!!!
I don’t know about spiders dream lives, but I do know pigs and cows dream, and the horror of how we treat them in those meat factory gulags, must make even sleep no escape for them.
Oh, I'm sure they dream, humans tend to think are special, but evidence has proven that we (animal, plant, planet or everything) are alike.
All though I'm courious if dreams have an actually evolutionary advantage or if they are a byproduct
Loved the vid
Your job is awesome
Take care of my little brothers and sisters 🕷️🕸️🕷️
of course they dream.. they have nightmares of being eaten by humans sleeping with their mouths open!!
I couldn't tell what stunns me more: the fact that she studies SPIDER SLEEP in the first place or the outcome of her research: That spiders obviously are having REM-SLEEP! 😯
You could watch for maybe twitching that looks like movement involved in hunting of different prey?
In the spider that hunts other spiders, since they have multiple types of hunting strategies, they might exhibit multiple similar categories of twitching modalities during their sleep
I'm against the sleep deprivation of spiders give them LSD at least
seen that old film. their still spiders and must die. i'll take their doses. whoops, already did today
Just don't let the crackspider hear about it or there'll be trouble!

We can know that humans dream without reports through for example the Tetris experiments which show humans dream of playing Tetris when they play Tetris all day because we can visualize it on fMRI. I recommend using infrared optical, scanning or two photon optical scanning on spiders and I have more experiments in mind , but a shortage of time. I can tell you 10 experiments that would show that spiders are dreaming and I think you have some in mind too. Don’t say something is impossible when it’s not. And don’t misunderstand skepticism of other minds because such a skepticism makes neuroscience impossible. Recall skepticism is a branch of philosophy and an important one, but once one gets on the boat with a natural ontological attitude (NOA), you have rejected the skepticism behind your sophomoric remark.

Just when I didnt think these little fuzz balls couldn't get any cuter. They sleep hanging upside-down!? 🥺🥺
Very cool research!
Thats a dream that is beyond terrifying to think about .
Somewhat unrelated, but I had a near death experience in Summer 2018 and got to meet the "maker" and talk to him about all the questions I had in life. I asked him if everything had consciousness or if sentient life was mixed in with bio-automatons. He replied: "Everything that dreams has a soul". Afterwards, when I came back here, the first thing I wondered was: "Do spiders dream?" Finally, years later, there is a video about the subject. How cool!
Cool Story, Bro
The bit about watching the eyes to see how they moved reminded me of this - All eyes have a common gene. That means that any creature with an eye has a common ancestor with any other creature with an eye. That means that if you see a creature that can see you then you are both looking at a distant cousin.
Surprisingly interesting!
"Spider sleep is human sleep?"
What a cool job. It would be amazing to one day know what they dream about. If we can even translate it into something we could understand
After finding the imago, Clarice Starling now examines sleeping spiders.
Salticids prove how awsome they are once again
interesting work. I have never thought to wonder about spider sleep, let alone do they dream!
that’s nifty. Jumping spiders are excellent.
Speaking of sleep deprivation affecting behavior made me think of the book, The Fly. At some point he describes a spider's web being repeatedly destroyed by the author and how the rebuilt web begins to become more and more disorderly. I hate to recommend depriving spiders of sleep and then seeing how their webs fare when destroyed in comparison with spiders that get an undisturbed night's sleep. There's a mad, amoral scientist lurking in is all.
Bravo to the music selection
Very interesting. Thanks for this!🙂
Videos like this make me glad I live in the information age ❤
My theory is any creature that sleeps for long period of time needs to sleep, to keep their vital functions minimally working to almost a reflex level. This of course exclude hibernating animals who have evolved to turn half their body off.
Heartwarming ...and, Cool. :)
"The world is burning... But hear me out... Spiders"
😂
A spider's dream. Hundred megabytes of memory. 🎶
He has beforehead, forehead, and afterhead. 🎶
don't like spiders. But man science is fascinating. This is awesome
The lab workers are so pretty 😍
Well they're not real scientists.
Amazing video. I studied dream analysis for years to become an analytical psychologist. Sorry to hear of the departure of the progressive editor-in-chief of your journal.
much like humans do, dogs process memories of their day while dreaming. since we’re such a big part of their lives, if you see them dreaming, there’s a very good chance that they’re dreaming about *you.* 🐶😍
Very cool research. Wouldn't surprise me if they are dreaming, jumping spiders anyway. I bet they dream about jumping, getting the angle right, the right power-boost, nailing the landing, and probably about hunting and evading hunters too, processing their everyday experiences. ... So, if even jellyfish and spiders sleep, does that mean sleep evolved once, w-a-a-a-a-a-y back, or is a period of rest advantageous enough that it evolved independently in so many different animals? Almost every living thing on Earth is sentient to some degree. Could REM sleep be a reliable indicator of greater awareness? For that matter, plants sleep, do they dream or is it just lights out?
Didn’t even know these things could fall asleep
We now have some dogs and cats possibly communicating using those big buttons. Maybe we could get self-reported animal dreams that way?
Best of luck to you Daniela
That absolutely blows my mind!😂 To think that even the tiniest spider sleeps, and possibly even dreams...it's beautiful!❤
Holy crap! I am so inspired by this video!
correction for 6:10
They recorded the dream of a rat by matching the neural recognition of a maze to a wave recorded while the rat was sleeping.
I think the bigger shock is seeing a large American jumping spider eating a giant Japanese jorogumo spider, because such a large prey would facilitate a larger predator, hence do we need to worry about hummingbirds and song birds eventually?
jumping spiders are so cool and pretty
Thanks for the analysis! A bit off-topic, but I wanted to ask: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How should I go about transferring them to Binance?
I did not know spiders could hear...
Bugs are very abundant and easy to catch for the jumping spiders, but the entire portia species decided to live catching other spiders just to show off 😂
Been saying it for years, jumping spiders are the puppies of the spider world.
Therapist "So how have you been sleeping?"
Jumping Spider Boing!

Quite a mind blowing fact that spiders do rem sleep.
Could heve sworn the title was "Do spiders scream like humans do?"
This sprung from the research of Charlie Kelly who found that spiders can in fact talk to cats.
That's a cool job.
I was unaware nonvertebrate sleep 🤔
im curious for an update in ~5 years its a very interesting topic!
Could you put a bunch in a PET scanner when they are sleeping ?
