They probably just yanked the spiders eyes...I don't think they would've gone through all that work of finding a blindfold for the spider . The spider had no consent ]:
That specific spider's eyes are very sensitive (so that they can see during nighttime, when their pray can't see), so much so that daylight temporarily destroys their retinas every day (since spiders don't have eyelids). They regenerate very quickly though. So the scientists probably just blasted them with light to blind them for a few hours.
That specific type of spider's eyes are very sensitive (so that they can see during nighttime, when their pray can't), at the cost of their retinas being destroyed every day by sunlight (since spiders don't have eyelids). They regenerate very quickly though. So they probably just blasted them with light and they were blinded for a few hours.
They blinded the spiders by using dental silicone. It is apparently like an epoxy where it comes with a base and a catalyst and has a putty like consistency, so easy to apply even to spiders. Don't worry, though, it is non-toxic and is easy to remove. So yes, they made small blindfolds.
@@Daniel_45 I am impressed you thought of this method. However, there is a small problem with this. You would have to confirm their retinas were destroyed, so that is probably why they just used dental silicone, like my previous comment mentioned.
4:22. Tim Storms: Hold my beer*. Just kidding though. I really enjoyed this video. Off to learn about sight now. 😊 *The lowest vocal note produced by a male is G -7 (0.189 Hz) and was achieved by Tim Storms (USA) at Citywalk Studios in Branson, Missouri, USA, on 30 March 2012. Timothy is the bass singer for the vocal group 'Pierce Arrow'. The attempt was witnessed by two college music professors and an acoustician. The frequency output of Timothy's voice was measured using Bruel & Kjaer equipment (low frequency microphone, precision sound analyser and laptop for post analysis).
Summary: Jakob Christensen-Dalsgaard explains the incredible hearing abilities of various animals, highlighting how they surpass human capabilities and utilize unique adaptations to detect sounds beyond our range. He explains the basics of hearing, emphasizing how different structures vibrate in response to sound waves and transmit signals to the brain. He then delves into examples of animals with exceptional hearing, starting with owls. Owls utilize their entire faces as funnels, have large and sensitive eardrums, and possess asymmetrically positioned ears to pinpoint sound direction. Their wings are also designed to reduce noise, allowing them to hunt silently. Christensen-Dalsgaard then discusses animals with exceptionally large ears, like the long-eared jerboa and fennec foxes, which allow them to detect low-frequency sounds and regulate body temperature. Ogre-faced spiders, despite lacking ears, have sound-sensitive receptors on their legs, enabling them to catch prey even when blindfolded. He also explores animals that can hear exceptionally high frequencies, like toothed whales and bats. They emit high-frequency sound pulses and use echolocation to navigate and hunt. He then introduces the greater wax moth, which holds the record for the highest frequency hearing among animals. Finally, he discusses animals that are sensitive to low-frequency sounds, such as baleen whales, snakes, and Namib Desert golden moles. They use different methods, including their skulls, jawbones, and body orientation, to detect vibrations in the ground or water. Takeaway Points: Animals have vastly different hearing abilities: Their range of hearing surpasses humans, extending to frequencies beyond our perception. Hearing adaptations are diverse: Animals employ unique structures and mechanisms to amplify, focus, and detect sound waves. Hearing plays a crucial role in survival: Animals use their hearing for navigation, communication, hunting, and predator avoidance. The world is full of sounds we can't hear: Animals can perceive a vast symphony of sounds that enrich their experience and shape their behavior. Understanding animal hearing can enhance our appreciation of their world: By learning about their sensory experiences, we can gain a deeper understanding of their adaptations and ecological roles.
Channels like this made me discover my own fascination with animating, and I put out 90h of work culminating in my first video the other day - if any one of you is dying to quench their unhinged animated storytelling thirst, perhaps stop by for a laugh 📌
I think most people can hear, and all hate, the sound of a mosquito flying! nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnniiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Honestly, our government has no idea how much people are suffering these days. I feel sorry for disabled people who don't get the help they deserve. All thanks to Miss Maria, imagine investing $1000 and receiving $5700 in a few days....
I want to say this because I just gotta. I HATE how you guys change the thumbnail, like, an hour after you put a video up. The first time was perfect because it got me excited to see the answer to the riddle. Now that I know it's about an animal before I watched it, the mystery is gone.
Imagine making a video about the amazing hearing that animals have, but then making the music in the video so loud that you can’t hear the narration…..

You can't say that scientists blindfold spiders and then not explore that in great depth. Please do a video on that!
Exactly. How does one do that?
Dental silicone, which sort of makes sense when you consider how sticky it is.
They probably just yanked the spiders eyes...I don't think they would've gone through all that work of finding a blindfold for the spider .
The spider had no consent ]:

@@Daniel_45 The spider still had no consent ]:
Being EARly has me smiling from ear to ear.
Smiling friends
This channel is dead
@@FourFourTwo123 - Your comments help to keep it alive 😇
I hope you never comment on a video ever again😇😇
That movement from the close up to the spread of wings was really cool
How did they blindfold spiders? :0

The bug in the ear was giving me Wrath of Khan feels…
2:57 Glad to _hear_ some acknowledgment that dolphins are whales. A lot of people seem to be unaware of that fact. Law of monophyly for the win!
🐍 4:35 sounded COOL with headphones 🎧 on! 🐍
I straight up just put headphones on to see what ur talking about
My dog when I open a pack of food
I mistook that title for some kind of riddle.
Yeah thought it was gonna be a video with a collection of riddles or something idk… got excited lol
@@mynamesak same😂
Spot on!! That's why I clicked 😅
Did they change the title because of my comment?
0:15 my dog looked up when the whistle played lol
Always love the animations but the bee’s wings in the beginning were especially charming!
Absolutely! And bats
love the falling tree pun at the end😂
I have a test involving sound tomorow, thanks for helping to remind myself
Every time I think the animators can't outdo themselves this time you guys 2 up me
love the art style!!
My phone has no ears but can hear me
Good thinking 🧐🧐
It has though
Isn't a microphone just a digital ear?
Did we have to have the vole kids be present for the snatch? 😒
I can hear best it's amazing how big brains and adequate everything else can lead to microphones that can out do any of these animal ears
i love the art style on this video, the owl especially looks so silly 😂❤bro really said .v.

"which animal can hear best?"
anything in a very quiet room (or not)
This video has some really cool facts!
Exceptional

Hawk Moth: "I can taste sound." 🧐
Headphones on this makes the sound bounce from ear to ear
All that for a tree-falling joke. WORTH IT!!!
1:54 brutal 😢
The scene when the bee flies inside the man's ear wasn't necessary 😖
i love tedEd animations.. I hope one day I can make enough money where I could pay one of their animators to do a video for my channel too! : ) : )
I think most people can hear, and all hate, the sound of a mosquito flying!

these animals can hear because then animals can understand everything

Why have I never heard this
Love from India🇮🇳🇮🇳🤞
Very interesting
“Like when a tree falls in a forest no one hears it”

I have no ears and I must listen (to Ted-Ed)
So what grade is this again?
I am drifting deep.
"even after being blindfolded by scientists"
My mother when I was 6 years old. 😢
Thanks
Only OGs remember that the original title of the video sounded like a riddle
You can reference to an animal as "someone"? I thought "one" in this context only refers to humans.
I'm favoured, $28K every week! I can now give back to the locals in my community and also support God's work and the church. God bless America,,
Investing in crypto/forex is a good idea,
a good trading system would put you
through many days of success.
Investing $15,000 and received $174,000
Yeah, 253k from Harrick Maria, looking
up to acquire a new House, blessings.
The very first time we tried, we invested $1000, and after a week, we received $7,500.
That really helped us a lot to pay up our bills
Honestly, our government has no idea how
much people are suffering these days. I
feel sorry for disabled people who don't get
the help they deserve. All thanks to Miss
Maria, imagine investing $1000
and receiving $5700 in a few days....
I was expecting decibels, but all I got was hertz. Shouldn’t the animal that can hear everything be the one that can detect the lowest decibels?
can the sounds really be heard from this video? my plate cracked😂😂
Ted -ed sugestion to next history video: Los Angeles ritos of 1992
1:59 😱😱😱😱😱😱
I'm ear-ly
I didn't know there was a Muad Dib like mouse here on earth🐀📖
I want to say this because I just gotta.

Supposedly many channels do this because it helps pull in more views.
So, who has the beat hearing again?
Haven’t watched yet. My guess: Spiders!!! More specifically, insects.
Corn ?🌽 😄
THE SOUND IS A TED ED VIDEO 😂
Who has no ears but can still hear?
A SNAKE..!
👇 please put a like here...I've not reached above 100 likes I my whole life...!😅
Muadib!
2:04 MUAD'DIB!!!
My inner thoughts 😂
In order to hear something...you need to listen.
Snakes was a surprise
Hiiii dear friends ❤❤❤❤
Easy. It's my girlfriend while i'm on the phone
And orcas. 3:02
❤❤❤
How do scientists blindfold spiders anyway?
I'm 'Ear *ear* ly!
Is hearing free will or not?
I wish a teacher plays this soon DX
"What has ears but can't hear"
No offense but that's a deaf human.
