Why do spiders have 8 eyes? It’s a seemingly simple question with a surprisingly complex answer. We’ll be hanging out with some jumping spiders (the cutest of all spiders) and some jumping spider researchers to investigate how a thumbnail-sized creature with a poppy seed-sized brain ended up evolving some of the most advanced eyes in the animal kingdom, overcoming a few limitations of physics in the process. We’ll watch as scientists study these spiders in a special eye tracking machine and learn how having 8 eyes instead of two gives these elite predators almost 360˚ vision and almost hawk-level depth perception and resolution.

Hello
Potato approves this dad joke
Very punny, and as a dad I love it.
Even though the best looking spider is the one on the bottom of my shoe.
Check out the posts by peacockspiderman.
A while back there was a little fly in my room that was driving me nuts. But then it flew into a corner and was quiet for a while. I thought maybe now I could sneak up on it. But when I located it, I saw that a jumping spider had actually beaten me to it. Thank you, little jumping spider, you have done me a great service.
He lives rent free in your house now

murder an eating the evidence...
You gotta have the full chain to keep pests under check. Insect->predator insect->Lizard->Birb->Cat->Dog, wait dog and cat can be friends.
This is exactly why I keep spiders around in my house. They are my friends.
A jumping spider chasing laser pointer just like a cat is the cutest thing ever
He probably blinded that spider with that doubled-frequency IR+green laser pointer...

@@jose.montojah Good question but relax. I'm more concerned about how they removed that adhesive.
But this is PBS that condone's Fauchi's Sandfly based Beagle puppy face eating abuse "for science!" yet all these media prostitutes will condone such activities for political social credit points much like your average prostitute.
Look up 'Fauchi beagle sandfly experiments Tunisia' words... and why these experiments and other activities are currently illegal in The United States.

The spider researcher/PhD candidate is my best-friend Alex. His research is awesome and he is making a lot of progress in the field!! It was awesome seeing him on this!!
A) his enthusiasm for his topic is contagious, and B) he's almost as adorable as the jumping spiders he studies
Fantastic !
It must be so strange seeing your best friend on a channel thag millions others watch and think nothing of the person, but to you he’s your best friend yeuwywu
If I could do his job, I'd never work a day in my life having so much fun. I'd love to keep tabs on what he's looking for and finding.
Welp, now I know where I'm going to apply for college. Spider University, here I come.
You need to talk about jumping spider cognition. Their eyes have some amazing properties, but their brains are even more fascinating.
How can such a tiny creature solve problems the way they do?
Surely these cute guys hold many secrets for future robotics engineers to emulate.
I was thinking something similar. I mean, if we could emulate this level of cognition at the same size, the prospects could go as far as nanotechnology, or even spacefaring (light sails would be much easier to produce if we could jam full blown sentience at the size of a sesame seed into it)
dragonflies also have amazing "brains" (not sure if their nervous system counts as a brain) - they can calculate & predict the 3D trajectories of their prey and intercept them, making them the most successful hunters on the planet!
@@threemooseqateers9689 It'll eventually happen. If we could redirect the global 2 trillion dollar military budget into something that actually helps humanity, rather than keeping a few psychos rich, then it'll happen even sooner. A human-like sentience could be under and over-clocked if running on a non biological substrate, making it ideal for interstellar travel.
@@MalcolmCooks Indeed!! I caught hundreds as a child and they never ceased to fascinate me with their incredible reaction time and flying ability.
they only have one brain cell
I've been a big fan of jumping spiders since I was young. I'd often carry a zebra spider around with me at school and always loved how curious and self-aware they always seem to be, gazing at everything with awe with those big round eyes.
Like, in a jar, or something?
Nah he defo carried it around on his ear
Other spiders are looking at you too! Jumping spiders only need to turn their bodies so much because they have specialized forward-facing eyes. It's true jumping spiders are the most intelligent spiders, but that doesn't mean other spiders aren't curious in their own way.
@@bugjams The brain power involved in acute and accurate telescopic/stereoscopic vision processing makes most current politicians in power look pretty dimwitted in comparison.
Glad to see PBS do something just educational and not political for the last ten+ years.
I miss proper NOVA.
@@bugjams That's actully completely wrong. Jumping spiders have the ability to aim their two main forward-facing eyes independantly giving them pseudo-binocular vision. They move their bodies around because they are actively gathering data about the world. Most other spiders only gather visual information passively, in the same way that eyes 3 to 8 do in the jumping varieties, picking up light levels and movement. This means that most spider eyes are useful only at very close range and are adjunct to motion and chemical senses. Jumping spiders, like most active predators use vision as a primary tool and do not need to build webs to catch prey.
In my garden there are thousands of jumping spiders crawling around. They come in different sizes and colors. It's amazing
What color is your spider ?
My absolute favorite spiders. :)
You must be the friendly neighbour
Maybe pretty to look at, but can you even enter your garden without getting tons of irritating bites? Or do you wear something like the beekeeper's suit?
Where is that? I want to live there!
I have a pretty hard-core fear of spiders, like full-blown arachnophobia. Yet jumping spiders don't seem to even register in my monkey brain as " *spider.* " I just find them super cute and fascinating to watch. They're such intelligent little creatures, especially considering they have a brain that is on average the size of a sesame seed! But when you watch th, you can actually see them investigating and processing the world around them. The comparison to cats is actually really apt. I really loved this video. Great job, Joe!
Yeah I feel the same about jumping spiders. "Normal spiders" usually scare me so much that I freeze in place but jumping spiders have this cuteness to them that is hard to explain.
In my mind, you've just laid out why your fear is irrational.
@@itsafunnyoldworld Oh trust me, I know. But knowing it's irrational doesn't do anything to fix it. That's what makes it a phobia.
They're just sooo curious and so adorable. I like to think them as cats in a spider form.
Then you have racismarachnophobia
All of them look so unrealisticly cute that sometimes I start to think that they are 3D modeled.
It's always so heartwarming to see more people championing the appreciation of the wonderful creature that is a spider.
My wife is terrified of spiders.
She wouldn't watch videos on YT and thought that the only good spider is a dead one.
I started following a channel who makes shorts about these precious things, and had her start watching them with me.
As a result, her disposition has changed, and when a larger or non-jumper startles her, she no longer immediately wants it dead.
Only a small percentage of these fellas can cause real harm, and even less are aggressive enough to chase a human and cause harm.
They likely do so much more for us as mosquito and pest control than they can by biting humans. If you think about it, they are saving many more lives than they could ever take. They're often one of our natural lines of defense against malaria.
A specific species of Jumping spider in Uganda, Evarcha culicivora, is drawn specifically to female mosquitoes who have recently filled up on the blood of a host.
I was watching a documentary that talked about how jumping spiders could map the canopy around them in 3D so they could backtrack through the branches in order to come back out on a certain branch just above their intended prey. They can plan...they think. They have a limited memory, which is something other spiders cannot boast. I've had so many people talk about how they train their tarantulas. Yea...can't be done. Their brains don't work that way, but you'll never convince them. lol Jumpers are amazing!
The book "Children of Time" is deffinitly fun for taking the jumping spiders to a potential extreme, the size of medium dogs, intelligence on par with humans, a culture and technology unique to them, all wrapped up in a scifi story with 2 sequels.
Deffinitly given me a newfound respect for Jumping spiders and Spiders in general
Best part of the video, Joe interacting and talking to the spider like it's a wee baby.
Im exactly the same way. I used to hate spiders untill I found a really really tiny one on my dads porch and it fascinated me. Then over the course of years I've become more appreciative of spiders however Jumping spiders will always have a special place in my heart, cause they have so much personality and are very cute.
Jumping spiders are so unique compared to other spiders. Their little personalities and adorable eyes are just too much not to love! Plus they’re so smart, they put other spiders to shame.
Growing up in the countryside of rural of North Texas, I’d see them all the time and came to appreciate them since they’re not aggressive or venomous like other spiders, but instead helpful to eating insects.
I hate to break it to you but they are venomous, but not in a medically significant way to humans.
@@Hurricayne92 i Think they meant not venomous to humans
You are right, Jordan. Jumping spiders appear to me to be exceedingly intelligent, sentient creatures. I have numerous living in my apartment & it's a privilege to me. I now live in Sydney where we are always on the alert for the deadly funnel web spider but I grew up in the bush in Queensland with spiders all around so I also know these spiders from my childhood & have always been captivated by them. Redback spiders, trapdoors and gigantic golden orb spiders everywhere but we did not kill them. When the farmers sprayed insecticides, many invertebrates disappeared from my homeland but now that such is banned, all insects & of course their nemesis, spiders, have all made a big comeback.
Did you really think other spiders were just out to mess with you? Venom is precious for obtaining food. Anything too big to eat is perceived as a threat. I've never considered any spider aggressive.
@@katiekane5247 As a kid I was naive, so yeah, I felt threatened by them and thought all spiders were dangerous. Only ones that didn't scare me were the zigzag orb weavers w/ their cool webs since they never seemed to move.
I love jumping spiders. I've never thought about it before, but they do have a lot of similarities with cats, which I also love.
When I was nine years old, I watched a zebra jumping spider track and catch a tiny inchworm. It watched the worm and hid from it whenever it moved its head in the spider’s direction. It reminded me of the nature docs I’d seen where some predatory cat was stalking its prey. It displayed all of the same moves! I’ve been a fan of these little predators ever since.
Finally, I am literally waiting for you to cover jumping spiders. They are adorable and awesome at the same time
What got me into spiders (well tarantulas and inverts) was the green bottle blue tarantula and the carabiner versicolor. They have the most amazing transformations from sling to adult. Scorpions are kinda cool also under UV light (they glow bright green/yellow like things in comics do when radioactive). Really cool to look at inverts under a microscope also.
Brilliant explanation of how the eyes on these little beasts work. The best I've seen. And thank you for using some of my footage! @2:39
Nothing like a jumping spider! I liked them even before I saw close-up images and videos (well, when I was young, TV was all the rage). Their curiosity is really astounding - they are really like cats in this regard. On the other hand, there's nothing as cuddly as a cat. And cats can purr! But learning about jumping spider eyes was really great.
The only reason jumping spiders aren’t cuddly is that they are too small. But from now on, all fairies in stories are required to keep jumping spiders instead of cats.

@@ginger-ale7818 I second this! 😁
Very interesting. Regarding the "best" eyes, the Mantis shrimp might beat spiders, at least with the spectrum of wavelengths they are sensitive to.
Another cool characteristic about jumpers is the way they can travel. In a breeze, they can point their spinnerettes down wind and start releasing a strand into the breeze. As soon as the wind drag is great enough, they will let go of the surface they are standing on and fly away. That's called "Ballooning".
I have also seen them reverse that when the breeze is strong enough. they will anchor a thread on the edge of a surface, and step off, letting the silk out until they contact another surface... like repelling - laterally.
It's amazing what you will see if you sit quietly and pay attention.
One interesting I heard is that while humans don't have such complex eyes our vision overall is still on par or better than them solely thanks to the bigger vision processing section of our brains is significantly bigger than them. It shows that how the information is processed is just as important as how it is gathered.
Mantis shrimp eyes are honestly overexaggerated. They can't "see new colors" as so many buzzfeed articles claim. They're sensitive to more wavelengths, yes, but in their little shrimp brains, those wavelengths can (very likely) only be turned into about 3 colors. A comparison might be how dogs can supposedly see UV light, but still end up being mostly colorblind.
@@bugjams Yeah. They can see 12 wavelengths but because of the limitations l of their brains they also can only see about 12 colours. Human eyes can only detect 3 wavelengths but thanks to our brains processing power we can combine it and see a million colours.
I had a pet jumping spider as a teenager, I loved him so much! Even now I get excited as hell when I spot one of the little guys outside, they are so damn cute. Thank you for all the neat close ups of my fave spider friends.
Jumping spiders are so fascinating! Our crew filmed archerfishes, and guess what? We found that they are masters in Physics. They are so precise in their hunting skills that you see how many things they need to take into consideration before shooting a shot of water!
My favorite is Portia. Intelligent (for an arthropod) and fascinating. Their hunting strategy is amazing.
Thanks a lot for this video! True story: I must have been about 5-6 in primary school here in Mauritius, being both dyslexic & hyperactive, I often was a headache for my teachers as you can imagine. On one of my frequent trips to stand in the corner of the room for being naughty, there was a fly buzzing about & came to land on the window in front of me. It was pretty annoying but suddenly the buzzing stopped as a jumping spider leapt out of a crevice & snatched the fly, off the window, while it was buzzing. That was it! I was hooked onto this incredible spider who had performed a feat of physics that blew my mind. The teacher told me that my time was up in the dunce corner but I did not want to leave, understandably.
So happy to see a video on my favourite species of animals! All spiders fascinate me (I even have a pet Tarantula), but jumping spiders especially are just a marvel of evolutionary engineering, in my opinion. Something so small, yet so effectively deadly, occupying (almost) every corner of our planet. Just love em.
Never thought I’d be so invested in a video about spiders’ eyes. 😅
For me, it's not the eyes that appeal to me but the way they compact their bodies when falling. Their legs come together into a single round pill-like structure that's strong and resilient. All the other spiders have legs just pointing in every direction with no elegance at all. But jumping spiders are literally built different.
So … like a cat.
@@meadow-maker
More that both have a landing strategy that isn't "aaaaaaahhHHH _splat_"
it makes sense. if they're gonna be jumping around to catch flies and other prey, they gotta have a fail safe in case they fall.
@montgomery_gator_enthusiast Oftentimes that failsafe is a tiny almost invisible thread of silk that they attach to a surface as an anchor before jumping.
I held a jumping spider once that decided to leap off my hand, I thought it was cute how it dangled for a second before pulling itself back up using the safety line.
If you ever watch one jump a large distance, you will notice that, like spider-man, they will attach a silk line behind them as a fail safe in case they miss the landing!
I already loved jumping spiders, but now knowing that they are the cats of the spider world, I love them even more.
Jumping spiders were my “gateway” spider. I call them the puppy dogs to the spider world. My first one used I sit and watch videos with me. My tarantula isn’t interested. 😂 #PhidippusRegius #JumpingSpider #Spider #Arachnophobia #AfraidNoMore
My teacher recommended your channel and now I know why! Your videos are great!
They are sooooo adorable! I love when I find a jumping spider. Now I appreciate them even more than before.
I literally want a jumping spider now. I normally hate spiders, but these ones are just so cute.
Since reading Children of Time I've grown to love jumping spiders and notice them everywhere. They always seem so curious with their timid approaches to a finger or hand.
I just finished the book, so it was quite a coincidence!
This book is good at so many level and absolutely deserve to be better known.
Came to the comments to shout out that book, glad I am not the only one!
Long live Portia and Fabio!
Okay, I Am Going To Amazon RIGHT NOW To Find And Buy This Book! I Love Jumping Spiders And I Love Books!
I love spiders; for me, jumping spiders are like the puppies of the spider world - a bit restless, curious, and they'll follow you around!
"What’s good for spider bites?” a person asked the doctor.
To which the doctor replied, “An irate spider.”
Love the dad joke bro 👍🤣😂🤣
I don't get it. Is it because the doctor misunderstood the question and thought the patient asked what makes spider want to bite people?
@@ioresult Dude, seriously?
@@itsafunnyoldworld maybe because English is my second language? Usually I get these jokes when I say them out loud, but not this time.
@@itsafunnyoldworld I'm a native English speaker, I read the post 5 times and said it out loud 3 times; I still don't get it. That being said, I've never been known to be quick on the jokes.
Once, a jumping spider landed on the neck of my cello. When I moved the cello to get a better look, it jumped onto my cheek. When it launched itself off of my face, it stung!
I also once watched a territorial dispute (or so it appeared) between jumping spiders in my bathroom. One had caught some prey, but the other seemed to take exception to that because it ran up and chased the first one off. This made me curious about the social dynamics of jumping spiders, so if anyone here knows anything or has an anecdote, please do share!
Apart from mating, jumping spiders aren't really social spiders and will sometimes prey on other jumping spiders. Some jumping spiders are even specialised spider-hunters.
There is brillian segment from BCC Earth''s "The Hunt" about the Portia genus.
ua-cam.com/video/UDtlvZGmHYk/v-deo.html
jumping spiders have very tiny claws at the end of their paws (not sure if its called that but they look like it!) that they use to cling on to surfaces. might be why it stung a little bit when it jumped
Thats my nightmare when I'm practicing 😂
Also a string snapping and hitting me in the face haha
It's a bit amusing that in many ways so are jumping spiders more social with us then their own species.
I'm in the same boat. Horrible, literally paralyzing arachnophobia as a kid and young adult. But I moved to Eastern Washington a few years ago, and we have these *huge* jumping spiders that are legitimately adorable.
I still abhor the various wolf spiders and yellow sac spiders around here though.
Lucky you're not in Sydney (Australia, not Canada), Eric. We live with the terrifying Sydney funnel web spider. Have a look on the web to see this monster. What's more, it's violent & aggressive and will strike several times with huge fangs & deadly venom. Not many deaths but makes humans very, very sick. We only discovered the antivenom about 30 yrs ago. Even so, you do not want to meet a funnel web. There are numerous species along the east coast of Australia. We also have the redback, a cousin of your black widow, but it's nearly everywhere here. Again, not too deadly but very painful & debilitating to humans and once again a terrifying monster in miniature. Thank mother nature created the jumping spider to redeem the reputation of spiders everywhere!
I live in Australia and always had huge dinner plate size huntsman spiders chilling on the wall in the bathroom, we never bothered them cause they eat other spiders 😂
I love jumping spiders, they're so cute I'm on the verge of tears 😍
Not as cute as the spider PhD daddy!
About 25 years ago, I was working on my roof on my hands and knees when I came face to face with a small, gray jumping spider on the roof slope above. I was actually a few feet away. I kept working but checked on him regularly. He was intently watching amd tracking me. At some point, he started doing their semaphore like signals. On a lark, I imitated him. The "conversation" lasted for minutes and only ended when my arms got tired.
That's a really cute jumping spider story!
They really are like little puppies and I'm so happy someone shares the same love for my favorite animal ever.
Awesome video! @3:30 - 04:00 is basically a behind-the-scenes of how I feel filming every. single. video.
I think it took the internet before people really came to appreciate jumping spiders. I always said they were cute when I was little and people thought I was crazy lol. I'm a fan of any creature that can recognise me, that looks at me. For example, inchmen are horrifying giant ants with massive jaws, but also seem to be so self aware. When you walk up to an inchman she'll stop what she's doing and look up at you in a defensive posture. It's adorable. What other ant does this?
Jack jumpers do this too, then come after you if they think you're a problem, they've got such attitude
@@kg6801 bull ants in general have great personalities, they are the jumping spiders of the ant world 😊
Jumping spiders are the only spiders that do not send fear into the primal part of my soul, all the others are straight from hell.
nah, they're more like the beginnings of your journey to start loving spiders. At least for me
I love this!!! Someone else who fell in love with the "gateway" spider!
All of this is neat. My favorite is how the Scientist does an eye exam for spiders.
My favourites are the myrmarachne (ant mimics) and the peacock spiders in Australia. But I really love all jumping spiders!
I love spiders 🥰This was cool to learn, for sure. Though I couldn't help but feel a little sad seeing the spider held in place with wax... I hope he didn't get too frustrated 😔
Luckily, the wax doesn't harm them and we can let them go after their tests!
@@bethjakob9052 I'm glad 💗🕷
The spider was a paid actor 😂
What I wanna know is how they got him wrapped in that white silky blanket thing in the first place 😅
I really thought I wouldn't be that interested in this video and before I knew it.. I'd watched the whole thing! Nature is truly amazing and I learned some pretty awesome stuff about the diversity of sight across the animal kingdom.
As a kid I always see them as the lower versions of other spiders since they're very common here where I live, but now I see them as the coolest spiders out of all, they love to move around, actively hunt their prey instead of ambushing, and they're so cute.
At 40 years old, why didn't I know these things about spiders yet? Thank you for sharing!
same thing happened to me, iv had arachnophobia since childhood but after finding videos of peacock jumping spiders, then taking care of a brown jumping spider over winter, who managed to lay 2 clutchs of babies by the way ^^ so cool, so i got to really like jumpers, and started to see other spiders as cuture becuase they remind me of jumpers.
Jumping spiders tend to be my more preferred species of spider since they tend to stay pretty tiny and thus aren’t that harmful or frightening to look at. Plus, yeah those eyes ARE pretty cute lol
everything in this video is crazy. BUT COLOR CORRECTION?? that’s just absolutely amazing
Great vid, loved the enthusiasm. Good idea getting the ento interview in there
This was hard to watch but in return I got to experience a bit of real wonder for nature. Like the recent ZeFrank videos on creepy crawly stuff. It was also cool to hear about that chromatic aberration correction stuff, which I learned about separately from the Vlogbrothers video on the Palace cat, and why it should have vertical eyes
Can we get more videos about spider eyes or animal perception?
They're so adorable! And yes their eyes and mental processing systems are insane.
How wild (though not surprising) to see you on this channel! You just covered bold jumping spiders on your channel and that was a treat to watch. 🕷 Love your channel and hope you keep at it!
Wow I've been wanting to see something on jumping spiders forever!!! They are my favorite type of spider in the arachnophobic kingdom! Perfectly exquisite and informative!!! Thank you for one of the best videos out there!
The fact that a jumping spider has a brain that can process the feed from multiple eyes is just amazing. They're so damn cute.
Perhaps it helps to think of eyes as not just dumb cameras that continuously send their images to the brain. But rather they act as an extension to the brain. A lot of visual processing already happens in the eyes themselves. The brain only starts to pay attention to what an eye sees when it gets a signal to do so. The motion detection mentioned in the video is an example of this. It's comparable to our sense of touch. Our brain is not constantly busy taking in signals from all the nerves in all of our skin just to check if something is touching us. But as soon as something is touching us, wherever, the brain becomes aware of it immediately.
(9:34) I wonder if the two "not really used" eyes are in the process of disappearing, growing, or...static, meaning that they _do_ serve a purpose, but are at just the right level of development to be useful. If the latter is true, then they _are_ "used"! (But I think I understand what you meant 😉)
Literally love this channel so much! You guys are amazing!
The was an awesome video!
Thanks for the mountain of info you've handed to us with this.
I wonder what the tarantulas and web-spinning species have so many eyes for if they can barely see. Didn't realize jumpers could move their eyes even if they aren't eyeballs, that's pretty neat!
I used to be afraid of spiders but, NOW I WANT A JUMPING SPIDER AS MY PET.
one can really tell your excitement on that topic, great video!
I've seen jumping spiders front eyes looking around, and it's absolutely amazing! So much logic and even curiousity packed in such a tiny creature..
I have built a little wal of bricks without mortar in my little garden in the center of Amsterdam, this wall gets warm early in spring in the sun. It is allways nice to see lots of little black incredibly fast running spiders on those bricks in spring. It is a pity that we don't have indoor jumping spiders in western Europe. (In the insect season I do have webspiders in my house, this year I had one which seemed to have figured out that me approaching her web meant isopod time, most spiders hide when something big is coming, this one went to the center of her web when I was about to feed her.
I'm more scared of humans than spiders,they are amazingly intelligent 👌 and they are great for the food chain eating other pests 🤩😍🥰 gotta love arachnids 👍
Edit:: liked,commented, subscribed and rang that bell for every notification, we need more educational and correct content on this here utube
0:30 Oh my gosh. I absolutely agree. I used to be terrified of spiders, then i watched one documentary about them and they had me change my whole mind and how i feel abt them. You spoke the words from inside my soul ❤❤
Just came across this, and spiders are among my favorite creatures, so I find it very fun. I also love cameras, so I find the optics of their eyes fascinating, and I love to take pictures of them. So a win-win. Nice video.
I used to be terrified of spiders. Then I decided to get over it. I concentrated on Jumping Spiders to increase my exposure and decrease my sensitivity. Cause, like Dude, they are stinking cute!
Well I'll be jiggered.. I didn't think there were any jumping spiders in the Yukon... there are 17 species represented! (found in a book called Spiders of the Yukon, go figure) Thank you, I love learning new stuff that surprises me.
Jumping spiders are super cool. I had the privilege to catch the sight of one hunt and it was amazing.
So I was at this tiny public toilet where the roof is barely taller than me, and I caught sight of a small jumping spider no larger than maybe 8mm hanging and crawling on the ceiling. It sneaked up on a moth, and jumped into it while hanging, as if it just turned a switch momentarily that flipped gravity upside down. It made no sense to me how it could jump inverted without falling, but that is what I saw.
I have always been interested in jumping spider vision, and this answered so many questions. Thank you!
You dropped the ball when you never told us what spiders look at during the dancing mating rituals
Bro really playing with a jumping spider using a lazer pointer 💀
I remember your old video where they put spider on your shoulder, and you were so distressed there :D
And now you brought us this video.
Absolutely fascinating !!... Thank you so much for this video ! I always wondered how these little creatures saw the world.
Well I stayed curious!
Could you make a short about how spiders see each other?
If their view consists of green and ultraviolet then their worldview must be quite interesting.
Do they have ultraviolet colors on their fur? Kind of like birds look much prettier to other birds compared to how bland most of them look to humans.
They do see in different light spectra. Some species also have reflective-like fur. It must look like satin to the spiders. Some evn to our eyes in normal light look bright blue ua-cam.com/video/gTdUAmJUo5A/v-deo.html
@@dcarbs2979 That is so odd and beautiful. Thank you!
@@immko What did their comment say? It seems to have vanished for me...
@@bugjams it was link to a video of blue tarantula.
While walking through an ER one day I was pounced upon by an intern who was seeing a pt. who had been bitten by a spider. The offending arachnid was presented in a jar for identification. I just said, "It's a jumping spider. Unless there's an allergic reaction to the venom, it's harmless." Nonetheless the spider was sent to the pathology dept. where the precise taxonomy was determined and reported. Lighter moments in E.R.s are treasured.
Appreciation increased! Thanks 🙂
I find jumping spiders around my apartment. I catch them for pictures then set them free inside the apartment. They are the most curious little things walking around and looking up at the camera.
I keep tarantulas and I feed the small ones mealworms. Sometimes the mealworms I take out of the fridge to warm up to room temperature go missing out of a cup that they cannot climb out of. I've seen these little jumping spider thieves, but I'm not even mad.
Idiocracy is finally here!! They have found their way to the science videos just to write ”first” in the comments
Other than "first"? Promotions.
Cute
I just dropped a cricket in my pet jumper’s terrarium, and it was really amazing to watch him hunt it. They really are like the cats of the spider world, truly. He kept his distance, assessed what he was seeing, determined it not to be a threat (and to be a potential meal). Then he followed it at a distance, and moved to hide whenever it looked in his direction. And when it was close enough and wasn’t looking, he pounced right on it, and sunk his fangs in right between the head and thorax (presumably to pump venom into the heart). He then dragged his kill up to a little perch to feed (much like an ocelot will carry its kill into a tree).
Every time I’ve seen a jumper take down a live cricket, they always nail them in that same “neck” spot. It’s amazing how accurately they can calculate their jumps, and how blindingly fast they are. One second, my spider friend was up above the cricket on a rock. The next, he was on top of it. My eyes weren’t fast enough to perceive anything in between.
I found my spider on the floor of my bathroom yesterday, looking very lost and very hungry (poor guy’s abdomen was totally deflated). I was happy to give him a home and a meal, and I was glad to see him eat. With the fall closing in, I didn’t want to drop him back outside without a home to go to before the cold sets in. So, he’s getting a more permanent terrarium home very soon.
I have two pet jumpers, Mimo and Deemo. They have such amazing personalities too, they're amazing creatures.
I’m watching this in bed

Such a cool video. Thanks. I'm all about that background: Voltron, Carl Sagan, Saturn V, shuttle with Hubble... I know I missed some things but, I'm all In.!
This was really cool and helps to defuse fear and misunderstanding of these amazing creatures. Thanks for doing this
Go Alex!!! Such an insightful episode
My deepest respect and love go to these fabulous creatures! Also to the people who use their time and knowledge to study them👍. Kudos🙏
3:45 the spider reading the vibrations of his voice 😂
I love spiders and metaphids are among my favorites. They -are- adorable.
The cuteness of jumping spiders despite their ick factor is inverted in the Hugo-winning novel A Deepness In the Sky, where the spider-like aliens think humans resemble icky soft grubs. Still, their helpless two-eyed gaze is as cute as a baby spider...
Children of Time is another great sci-fi book featuring jumping spiders. I highly recommend it.
I used to share a desk with a tiny spider that jumped enormous distances from one place to another, watching me and always interfering with my stuff. I'd shoo him away and he'd turn up whenever I moved about or sat down. I was watching him closely one day and he jumped in my face - I nearly pooped myself. As a spiderphobe I hate to say I missed the little guy when he stopped coming out to play - but I did.
never imagined i could be interested in watching the whole video !!!!!
I also had arachnophobia ,but knowledge has turned fear into curiosity and amazement ,I think I can now say that I love spiders,they are my friends and they are not up to get me,but to help me.
