Hearing in a jumping spider

- Jumping spiders are highly visual animals. They use vision in courtship and to catch food. Gil Menda in Ron Hoy's lab at Cornell University developed a technique to record from the brain of a jumping spider. This enabled him to study their vision but also revealed the surprising fact that some brain neurons were sensitive to both visual stimuli and to sound. It has been known for a long time that jumping spiders were sensitive to substrate vibrations, but this was distant sound. It turns out that they are very sensitive to sounds from about 80 to 130 Hz a frequency characteristic of their chief predator a wasp. When you play sounds of these frequencies to a walking spider, it freezes. Lacking any obvious ears, it is the trichobothria-long hairs on the spiders legs-which are the receptors.
You know, this makes sense, because when they're wet, they wipe themselves off, probably so they can hear the wasps.
no one thanks the spider in the end :(
Because theyre scientists, not youtube performers
I was thinking the same thing as I watched the credits at the end.
they use their little feet to to sense things as well. It's why they put they jump off your hand so quickly when you first catch one. They can feel your skin. I've had them jump onto my hand from a stick and instantly jump right back off again because they knew it was living tissue they had jumped onto. They also will touch your skin ever so slightly when you put your finger next to them.
If I understand correctly, they also taste with their feet too, or at least some spiders do, though I don't know much about that for certain
@@UNSCPILOT I don't know I'll have to take a look at that.
I'm wearing bassy headphones ;-;
3:42 made me legit screech
skatejam7 "....the waSSSpSSS!!!!"
Me to lol
Just had a mini heart attack
Same i threw my headset off
This means Lucas can hear his music. Yayy
wasn't expecting to see Lucas in the comments section 😅
My spider heard me. I made a little sound to get his attention and he turned instantly at me. It was so cool ! 🕷
This is so incredibly fascinating! Thank you for your research!
Now I know when I say good morning to my spider he hears me 🥺❤️
Spiders are truly amazing and incredibly intelligent!
I'd point you to Basin79's "Feeding My Jumping Spiders," in which his bird squawks rather loudly and his jumping spider reacts noticeably and orients herself to the location of the sound. This is all very exciting, though! Science!!
Have seen that video, can confirm!
Wow! Amazing work, I love these little guys and its good to know that they can hear me when I tell them I love them
I've seen a lot of videos about how cows like songs. Maybe spider friends like songs too idk
Outstanding! Way to go. This is what life is all about.
Thank you for bringing this to the public, as well as your dedication.
I love that you obtained unexpected results that, in some ways clash with previous expertise.
They feel sounds thru their hairs. Kinda like everything with hair on it! Why is this so amazing! Ughhhhhhh.
Guess how our ears work. The spiral shaped bit of the inner ear that is connected to the ear drum is filled with fluid, and the walls are lined with yep, tiny little hairs. Same basic principal, but ours is much more sophisticated.
You should contact a young British lad whos utube channel is called TARANTULA ADDICT. He keeps an array of large tarantulas, other species and other insects. He has trained his tarantulas to respond to voice commands like a dog would. He found out they could hear ages ago himself. He's a very interesting person and his love is the big goliath bird eaters. Similarly there's a utube channel called TOMS BIG SPIDERS. Another very interesting chap who is an American teacher. He also has a tarantula keeping hobby. This man is somewhat of a pioneer though because he has discovered, created and documented that spiders particularly taranchulas can live quite happily in a communal set up which was thought not naturally possible. They can nurture each other, feed each other and respect each other. They are capable of exhibiting affection towards one another and when in this environment they grow quicker in size and are more healthy with a much more often feeding motivation than the same species of the same age but kept in a solitary setting. He concludes that taranchulas are pack animals primarily but whom can chose to live alone
which has been fascinating to watch over the years.
Just watch the voice trick video, he says it's an april's fool joke
I know it is science. But it legit broke my heart seeing this creature caputred and getting poked in the head. Probably because i own some of them myself.
Broke my heart too.
Thank you little spider. He died in the name of science❤️😔
Good news: the spider didn't die! 😁
@@bradleyturek how could it survive with that glued on his head
@@XY-km8ds I think that the fact that it survived was one of the breakthroughs: they were able to avoid a "blowout" because of how small of a hole they made is what they said.
@@XY-km8ds and I assume the stuff holding it in place is a wax that they're able to remove without too much harm to the spider.
I'm pretty sure it didn't die...So it's all good 🙂🕷️💖
That spider is cute
Interesting, I know when I talk to one, it lifts its front legs and kinda cocks its head as though its actually listening to me!
Julie Jennings I love how jumping spiders will actually make eye contact and everything with you! :) they're so fascinating with their intelligence !
Thank you for your research, Very interesting.
For some reason I feel protective of them.
I thought spiders 'heard' through sensors on their legs? Through vibrations.
Edit: Nevermind, finished the video.
Now we need to find out what kinds of music spiders like! :D
Jumping spiders produce their own type of music by tapping the ground when trying to attract a mate, i found plenty of videos on it and its pretty interesting
Wow, what cool science.
My jumping Spider 🕸 likes soothing music.
This is very cool! What an amazing discovery. I hope the spiders weren't harmed in the process.
Victoria Long they were killed.....
:( That's a shame.
The Great DuCkTekTive, please provide a source. I couldn't find anything stating that the spiders were killed.
The spiders went to Starbucks.
Idk if the spoods were killed, but when they drilled the hole, i dont think the spiders were in pain.
Poor spider probably felt like the chicken in the intro to Robot Chicken...
How do they respond to being petted with a q-tip?
They did surgery on a (grape) spider
Don't the males create vibrations in their mating process too? They do it in sequences and patterns. And I thought it was known that the females hear this well through their legs.
Wow! That's amazing!
That is literally so freakin cool
Thank you fascinating and important information to be aware of.
I feel bad that the spider had to suffer, and die to find all of this out.
Same. Poor little one.
That sudden wasp noise made me jump...
3:40 Im not a jumping spider, but that sound is putting me so on edge ._.
I had headphones so the wasps sound wasn’t pleasant and I got distracted the whole time 😂😂 3D sound quality
Oh my poor spider has to hear my macaw scream too. 😄
Excellent. TY
I don't know why people always underestimate living creatures perception and understanding of their environment. Because we don't know what they think or perceive doesn't mean they don't think or perceive ! I still remember when doctors believed that babies could not feel pain, so you should operate them for this or that before they would be old enough to notice (or to complain ??). Before scientists discovered that bats had a superpower (echo-location), bats were evil creatures. Human beings are so self-centered that they even believe God has made them as per himself. Luckily enough, some of them are more curious than others. I love scientists : they can seriously spend their life trying to understand the world through the most unexpected magnifying glass, and searching answers where common people would not even have a question about ! 😊💜 This said, that wasp sound must be engrained in a lot of animal brains, because I startled on my chair two seconds before I understood it was in the video, lol.
Can you tell us something about the spider that is more endearing? Are they affectionate? Do they have emotions?
Susie Arviso some people keep them as pets. One man has trained his spider to give tiny high-fives with one of her legs against his finger, and he pets her very gently with one fingertip, which she really seems to enjoy.
Great job!
Fantastic research! Would love to study multimodal sensing (vision, hearing, and olfaction) in the brains of these little dudes!
When they here my loud Fart they scatter.
My brothers are always blaming "barking spiders" when he farts..😉🙂😂
Does the spider have to die for these experiments? I hope not
they pick up frequencies with there hairs you know it's obvious i've whistled at a spider and they run away compared to changing me (im in australia so all the experiments i want)
4:40 just made it to there so i was right
1:37 Jeff Bezos working on spider
So it freezes around the frequency of the wasp's noise, is that to avoid detection? Or a fear reaction?
I hope they figured it out. Now I know why wasps and hornets attack. Btw there been recent reports of hornets in the usa for a while
Love those spiders
Conduct an experiment and determine how jumping spiders respond to Nikolai Rimsky-Korsakov's song "Flight of the Bumble Bee"
fabulous
RIP little lab-rat spider bro
Hey Cornell why the fuck you gotta use actual buzzing insect sounds? It’s 4am, my window is open, and that scared the shit out of me.
Are they actually hearing or could they be feeling the sounds? Just curious
Close encounters of the third kind music works on spiders too I guess.
It IS interesting. The wisdom of small things.
We were having great fun
Maybe apply to hearing impaired?
Ok, great video. But, am I the only one reminded of Robot Chicken?
did the spider survive the hole ???
“And THEN we realized... the neurological probe wasn’t even linked to the jumping spider. It was linked to our scientist. And the spider escaped! Truly these are intelligent creatures.”
Say the plural form of “wasp” 3 times. Ssssppsssss. Now that’s all you’ll hear, you’re welcome.
Banshee's idle?
Maybe not hearing, but vibrations
Did you even call the spider the next day!!! After you had your way with it !!!!!! 😕
That seemed like a nearly complete waste of a perfectly good spider, with no useful research in spidey senses at all. It didn't show how well, how distant, what light spectrum, nothing.
Only that their brain responded to stimulus. They didn't know that?
I felt for that spider being tormented and would rather have seen them poking holes in each other. I did like the fly glued to a sm. paper airplane for a motor, though.
They did discover tiny holes were necessary for them not to explode, that's about it. At least it wasn't a Gov. grant... that could have cost $100,000, easy.
It's silly to believe but since they have never found an ear hole on a spider they believed them to no even be capable of hearing through the air and only through vibrations in the ground. This was an important baby step.
Poor spider 😭😭
1:25 this is not precision work...
Amazed that a spider hears and senses a clap, would be like an alien surprised we processed the audio from a 400 foot tall monster clapping its hands.
Just like us these things are animals and can hear and see enough to keep it alive, it is impressive to see the progress but not so much to see that an animals neuron network will process audio.... any creatures neurons would fire if A: they can hear and B: sound is played near by, like a clap
They were not be able to do? Uh, they do hear and feel. Who are you to say they don't!? Your not God.
So you tortured and killed all these intelligent spiders to figure this out? That's nice of you.
Yea man, you better use magic scrolls next time to acquire knowledge about an animal!
grnparanoid parchment scrolls..I mean wait..
Unfortunately, this is how we have made so many medical and scientific advancements. I'm sure most of the scientists don't enjoy torturing and murdering an animal, but it is important for us to know. Especially since many animals you just wouldn't think of as useful end up being applied in life saving medical practices.
If it helps, plenty of humans are tested too, though usually they are cadavers or volunteers now-a-days.
I don't think they killed or injured it at all. They held it still with a frame and some wax or something, massaged then pierced a very tiny hole in it's carapace. I think it wouldn't hurt it as it's insides are protected by that exoskeleton. They also stated the problem that the spider would die if the hole was too large or if the spider lost pressure. They work like hydraulics so they can't spring a leak at all. Also, notice the neuron firing on the computer? It's calm and has sensitive response. If it were in extreme pain or was dying then there would probably be more activity. I bet it was probably really uncomfortable though. Might have just a tiny bit of memory loss or brain damage. They would have patched it up with superglue or putty until it's healed. Next time it molts it will have a brand new exoskelton with no pin hole in it. I assume jumping spiders molt too. I'm still against this though, but you have to admit we did learn something from them.
@@MidKnightKid98 thank you for explaining that did put my mind at ease.
first
The wasp you refer to prefer TARANTULAS... even the picture you showed with a wasp and a spider was a drawing of a TARANTULA. Jumping spiders would be too small for the wasp.
