- Explore the incredible diversity of eyes and vision in the animal kingdom, and find out which creature has the best eyesight.
--
The animal kingdom boasts an incredible diversity of eyes. Some rotate independently while others have squiggly-shaped pupils. Some have protective lids, others squirt blood. But which creature has the best sight? Which sees best in the darkness? Which sees the most detail? Which animal sees the most color? And finally, which detects motion the fastest? Thomas W. Cronin investigates.

Glad they went with a 'best in categories' rather than just 'best overall' : D
That's cuz there's no best overall when animals specialize in specific survival needs
Yeah I was thinking that when I clicked on this!
@@Stevie-J Arguably blue human eyes
Best overall is a subjective outlook I’d venture to say your evaluation on who’s best overall is as good as theirs
In a thermistor the resistance decreases if the temperature increases. If it’s colder, it has a low resistance. They are usually made of semiconductor materials, typically metallic oxides, using cobalt, manganese, or nickel.
It is used in many places, for example in baby incubators and computer fans. The hotter a computer is, the more the computer fans rotate, thus they cool the computer down. Since in hot temperatures a thermistor has a low resistance, the potential difference is low. This causes the potential difference across the fan to be higher, rotating the fan faster. Potential difference is always shared across components in a closed circuit. However, the lesser the resistance of a component, the lesser the potential difference across it is shared, causing the other component(s) to have a higher potential difference across themselves, making them function more. This is how computer fans rotate faster when the computer heats up, cooling the computer down.
In baby incubator also when the temperature increases, the lamp turns on and alarm starts ringing. The reason is exactly why in a computer fan starts working when temperature increases. Baby temperature has to be maintained, so the alarm calls the doctors for fixing the problem.
In others words, the human eyes is a jack of all trades, but a master of none.
Edit: before you want to comment about the rest of the quote ("but better than a master of one"), please read the others comments so you will know that 40 people already said the same as you. I got it already. So did everyone else.
@@Stevie-J Who? Birds?
We consider ourselves as a jack of all trades when really we're just using ourselves as basis to understand things beyond our reach. After all, we can only know with what tools we have. But we are just as special as every other animal is. We just excel in ideas and changing our surroundings.
@@wilfweNightsky no, comparing to all other animals, we are about a bit worse than average in every point for eye sight.
Eh, better than being the master of only one.
@@HopeRock425 That's just not accurate. No other animal beats humans when it comes to creativity, abstract thinking, tool creation and usage, or ability to communicate.
As Lord ZeFrank said, "Try to imagine a color that you cannot imagine. This is how a mantis shrimp do."
Like a lactose intolerant cheese maker, the cuttlefish is aware of its own gifts.
Ze Frank did a TED talk, too! (If you didn't know).

"Now do it nine more times."
Imagine being able to see peoples’ body heat or see an ant crawling up a tree from 600 feet away. That’d be trippy.
I have poor eyesight and the doc fit me with contacts after surgery and I saw better than 20/20. I didn't like it. Was fine for driving but up close it was unsettling.
@@Roof_Pizza interesting
@@Roof_Pizza you were seeing too much detail lol
@@AyubuKK If I had OCD I woulda killed myself cleaning.
@@Roof_Pizza Oof.
Another awesome video on eyes. I really like these comparison videos of human traits against the animal kingdom. Top notch animation as always! 🤌
Eye know!!!!
Eye thought so too 👍
Have I mentioned how much I love and appreciate this channel? You guys make me a better, smarter person with your clean cut presentations and smooth delivery of information.
Thank you for all your hard work.
Blah Blah Blah
You Are Right ....
Hehehehe
Sorry dont mind

Much love y'all
The Animation as always..was a " Sight " to behold 🙂
🙂

The music is so haunting, calming and beautiful! Thank you TedEd!

Promissed Excellency.
“When it comes to the sharpest vision, birds of prey *soar* above the competition.”
Lovely, just lovely….
Similarly, “…on the fly”
The music is so pretty on this one! My admiration to the sound team!
The reason for the color change in reindeer eyes is because during the winter, its pupil remains permanently dilated, causing increased pressure in the eye that compresses the structure of the tapetum lucidum. The constant pressure squeezes fluid out between the tapetum lucidum's collagen fibers, and they become more tightly packed. The spacing causes the reflection of shorter wavelengths, hence the blue color. In the summer, the pressure is relieved and the eye reflects a yellow to green wavelength.
Cool
Many times I imagine what it would be like if a person’s entire retina were like a macula. We can’t even imagine, because if we could see perfectly with the whole retina, which zone would our brain be paying attention to? The one thing is that our vision, even in such a limited version, requires a lot of capacity for the brain, so I can’t even imagine seeing it sharply in every corner.
I completely agree!
One would need to have a brain (or brains) that could focus on more than one thing at a time.
We are limited by our mental capacity. If we were suddenly given a dozen more color receptors, our brains wouldn't know what to do with them. It would have to allocate more processing power to the new eyes to be able to use them, leaving less room for other processes.
I don't think any animal uses the whole eye the same way. We can't perceive everything we see at once. It is mainly focused on what is in front of us. That is why you can't read a book off in your peripheral vision. The front of our eye is better at seeing color and detail while the sides pick up motion better. Also we are blind in the dead center of our eye because of the space needed for the optic nerve, but our other eye makes up the difference and our brain fuses the 2 images together.
If we do have that capability, then we wouldn't need the ability to move our eye balls, which is one of the main tool we use in nonverbal communication. We are very sensitive to small changes in gaze, and dogs are sensitive to ours. But curiously, even our closest cousin, the chimps are not.
So it MIGHT be the case that if we had that ability, we wouldn't have been so good at socializing and cooperating, and hence wouldn't have been the dominant species.
It has been like what 9 years and this man's voice still hasn't changed one bit... That's true dedication to a channel
What a beautiful animation style! Ted-Ed is absolutely brilliant
I think this animation is your best yet. Colorful, precise, elegant, smooth. A masterpiece.
The animation, combined with the background music, makes everything seems so at peace & calm
This channel is the greatest thing that happened to me! I am someone who tends to question soo many things in this crazy world, and often get weird looks for that. But this channel has awnsered the even most bizarre things ever, which i might have never thought of asking nor thinking of! I love learning new things and this channel has been feeding me with information every single time. Keep up the great work :)
Thank you Ted Ed for making videos that contain a lot of information.
Love this topic, as well as all your videos on it. Really interesting to know about the huge spectrum of visual perception across species! Humans may not be the best, but we can rank decently in everything, and that may have given us a surprising advantage.
Hats off to the animation, as usual!
Actually we got the Widest Range of Colours, so we have the best Colour Vision on the Planet
Me struggling to read the title when I got the notification on my phone: "well its clearly not humans"
LMAO, Vision is the Strongest and the Best Sense of Humans followed by Hearing and Touch, Nature didn't give us one of the Best Eyes on The Planet Earth for you to complain about your Skill Issues
This channel keeps answering questions I didn't ask, but I needed to know the answers to. Keep it up
POV: you’re watching this at 1am in you’re room and you so tired you can barely see
Background music is so calming.
Never really noticed until this video, but the background music fits the topic very well! Awesome job Ted-Ed, *see* you next time XD
I am a college student who is supposed to be getting my work done, but I found this video very informational and very much worth my time.
I would love it if you guys did more book recommendations, I read Lord of the Flies because of your great video in it.
book recommendations are some of their best videos
I agree I agree I agree
@TommyGaming 🅥 BEGONE, BOT
@@Stevie-J On which platform?
@@Stevie-J Yikes! The only thing I can of is that they banned the quote based on the book it came from due to the faulty algorithm.
The music was gorgeous ❤
The sequel we have all been waiting for!
I think my mom has the best eye sight. I’m looking for something and can’t find it, but when she helps me look for it, she seems to see it right at that second.
Yup. Mum where’s my?
This is just too relatable!
Fascinating video, beautiful music and animation.
Loved the music, visually this was a great video and very explicative!
this is my fave ted ed video
its so whimsical
Thank you Ted Ed ☺️
Something I would of liked them to touch on is that humans actually can see UV, but it requires not having an eye lens, because the lens blocks UV. Famously the painter Monet had his left eye lens removed and his entire world changed with the ability to see UV light.
but having your eye lens removed is not convenient at all, so i dont know if that counts
That doesn't make sense. If you have to modify the eye to see an additional part of the spectrum then that eye can't see it.
how do you remove it surgery
@@m-h1217 i believe they mean that our eye/retina has the photoreceptors to detect lightwaves in the UV spectrum, but our lens filters these said lightwaves. it makes sense, and your statement is just semantic. Does an eye really need a lens for it to count as an eye? Did Monet still have two eyes after a lens was removed from one of its eye?
@@zumabbar Yes, I understood the meaning of the statement, thank you very much.
The comment states "humans actually can see UV, but it requires not having an eye lens" which doesn't makes sense as again, it literally states itself that unmodified humans can't see it. Therefore humans or rather normal humans can't see it. Pretty basic.
"Does an eye really need a lens for it to count as an eye? Did Monet still have two eyes after a lens was removed from one of its eye?"
This isn't relevant to what I said, an eye that naturally can't see a part of the spectrum can't see that part of the spectrum. The lens is part of the eye, so if you remove it, then you've modified the eye. When did I say that a modified eye isn't an eye?
TED-ED Is Here ❤️❤️ 👍🏻
the animation of this video is amazing, nice job as usual ted-ed
The way Ted brings knowledge for us is really great.☺️☺️☺️☺️
This is really eye opening
This is just amazing the comparison and all the details
Thanks Ted
Wow. This video was a real eye-opener.
I learned a lot of things that I didn't know before:-)!
At expo 2020 in the Russia pavilion you could see through see through the eyes of other animals and creatures it’s very cool! Another reason to visit the amazing Expo 2020
TED: Have you ever wondered which animal has the best eyesight?
Me: No, but now I do
Amazing music in this video. Loved it
The music was so magical, I wish I could listen to it without the lesson next time when I try and relax
Great video! A lot of new information and fun to look at. Thanks!
I found this so interesting. Thanks.
Fascinating. Brilliant topic. I am even more in awe of nature. Now I know it's a fly's photoreceptors that make them so hard to catch.
This had such beautiful animation
great music in this vid
I love the music in the background ❤️❤️❤️
BESTEST ANIMATION VIDEO BY TED ED. THE COLOURS 😍
Fantastically educational.
I get very excited everytime ted-ed posts a new video…
I was wondering if you could make a video explaining menopause. Your videos are very educational and I love it :D
Brilliant. Information and extremely entertaining. Loved it.
Great video luv u ted ed
Thanks for information 🙏
Please make more informative videos on Animal Kingdom.
Once u start watching Ted Ed u can't stop
I like the music.
Yay, another eye series! I'm loving this.
What a nice video!!
These are only a few channels that TH-cam is still alive as a decent platform
Great video. Thanks!
Fascinating subject, sneaky-effective teaching, delightful animation and soundtrack. Thank you, TedEd
I've always thought of vision as a compound sense. There is an image portion, a color portion, a motion portion, and then the processing software within our brain that blends and evaluates those inputs. And its possible for each of those to fail or work without the other. While in college I knew a guy who had what we called "blind sight". He couldn't see image or color but he could see motion. If nothing was moving around him, he was completely blind. But something moved, he could literally point to it or follow it. If it stopped, it's as if it disappeared to him.
Nice video.
4:37 beautiful music..
All these eyes and still none can see where my dad went
Awesome video
Well done guys
MY grandpa was partially blind but he could always see my shoelaces were untied. Amazing adaptation.
The music in this vid is gorgeous
The soundtrack is amazing
Now this is an extremely well made demonstrational video. Felt more like a video-game.
Life is a game.
This was so calming n tranquil to watch
Just what I needed for a nice relaxing poop 🙂
I'm so sorry for this comment, I've got the giggles from watching tons of Avengers clips
Whom ever made the music and Addison Anderson's voice is just perfect together :D
I adored the animation in this video
Really awesome
Kudos to the creators, you guys are awesome.
Another eye catching video
That is to say we can improve our eye sensitivity by using night vision google and our eye resolution by using binoculars and using high fps camera to capture high motion image for our eye to see by slow down it but we can't do anything with our eye color vision, am I right?
Been waiting FOREVER for a video about the Brownsnout Spookfish, which, imo, is secondary only to the Shortnose Batfish.
The animation and illustrations are
The music is perfect 🥰
lol that’s was super cool. Birds of pray are circling above my house , love to watch them how they are looking for food. 🐥
Leaving a comment to boost this video in the algorithm.
It's a good one.
Eyes are cool.
Having hawk eyes is literally the real life version of the Sharingan minus the reaction time
What an incredible lesson!
Can any tell me what music is playing in the background?
It is a composition made by a portuguese composer named Andre Aires
2:04 I would like to agree but I thought the dragon fly's would have the sharpest of sight 🤔
Creation is just awe inspiring
I was really hoping for the mantis shrimp colors to be discussed and Ted-Ed didn't disappoint. But now I wonder what eyes that were great in every catagory would look like
That would be impossible, as being good in some categories nessecitates being worse in others. The closest we have to a perfect eye is a camera
3:08 congratulation Ted-Ed you did it again.
You think we disn't notice it but I did
We went to the aquarium in Branson Missouri recently and they have a peacock mantis shrimp. It was so cool. Easily my favorite there now I can explain how amazing their vision is. We don’t even know completely.
In Nature, Everything is perfect and beautiful ♥♥
For me Mantis Shrimp has most extraordinary eyes, i love it.
I love your videos because there actually worth watching unlike everything else online 🤮
This is why there are so many different types of cameras and telescopes. Optics are fascinating across the board.
U guys should link the music if possible because the music impresses me almost everytime :)
