The Amazing (and Deadly) Science of Jumping Spider Vision

Check out Rogue History on @pbsorigins: • What Pop Culture Gets ...
↓↓↓ More info and sources below ↓↓↓
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.

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.

[@threemooseqateers9689]

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)

[@MalcolmCooks]

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!

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.

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.

[@badlaamaurukehu]

@@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.

[@LadyMoonweb]

@@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.

[@semaj_5022]

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!

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.

[@valentyn.kostiuk]

All of them look so unrealisticly cute that sometimes I start to think that they are 3D modeled.

[@PaulaLPope]

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!

[@UNSCPILOT]

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.

It's always so heartwarming to see more people championing the appreciation of the wonderful creature that is a spider.

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.

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.

[@buddywhatshisname522]

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.

[@AdamsWorlds]

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.

[@c.augustin]

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.

[@ginger-ale7818]

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.

[@Laserblade]

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.

[@minhducnguyen9276]

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.

[@bugjams]

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.

[@minhducnguyen9276]

@@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.

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.

[@PurtyPurple]

​@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.

[@keihan5]

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!

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.

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.

[@olavl8827]

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.

[@CybershamanX]

(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 😉)

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!

I used to be afraid of spiders but, NOW I WANT A JUMPING SPIDER AS MY PET.

[@klaasdeboer8106]

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.

[@chicken_person]

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.

[@fofer5586]

one can really tell your excitement on that topic, great video!

[@jaschabull2365]

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!

[@Scottbewilding]

You dropped the ball when you never told us what spiders look at during the dancing mating rituals

[@xekis]

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.

Go Alex!!! Such an insightful episode

[@scheimong]

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.

[@pamelapilling6996]

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!

[@yukonbikerguy]

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.

[@southernflatland]

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..

[@teriinka_uwu]

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 ❤❤

[@wholeNwon]

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.

[@immko]

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.

[@dcarbs2979]

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 kzbin.info/www/bejne/nYXHhnSjf7qia6M

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.

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...

[@sphinxtheeminx]

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.

[@jacobwindham3817]

This made me smile. Feel the same way about jumping spiders, they seem so curious
