The World Through the Eyes of Animals
ฝัง
- เผยแพร่เมื่อ 13 พ.ค. 2024
- Did you know that animals see the world differently from us? Pigeons actually have better vision than humans. Cows can’t see the color red because they don’t have the necessary receptors in their retinas for that. Horses have a blind spot right in front of their faces because of their eye placement. Fish eyes have ultraviolet receptors and a more spherical lens than humans.

How do people know what animals’ vision are like?
😂same
Warging.
Ils ne savent pas, ils ne font que supposer.
Maybe there's something like the Ishihara test that can be done on animals.
Science
I'm supposed to sleep, but here I am watching the world through animals' eyes.
Same here😂 at 2 AM
I can see their eyes if look into their eyes ,shake eyes,catch eyes.
1:24
Same thing here 😂
Who is here for cat vision like me😻😻😹😹
Me
This can see a dark
I can see you being famous my guy cat vision was my second favourite
Mee
What if the colours human can see are not actually the real colors? 🤔
Woah 🤯
It's time to prove with camera 😅
U experience it every day. When u r inside, and see a white wall, its not white. It depend what light using in the room. That is why u have white controll on your cameras.
but they are, we are seeing full spectrum in certain light frequency range, there's no gaps in it; however some animals can see frequencies out of our reach, e.g. ultraviolet
@@Mandrak789The light spectrum is made by humans, that means we categorized that spectrum in which *humans* can distinguish colors. There are are many more colors in other spectrums that we can't see.
Like we are able to see shades of 3 distinct colors (RGB and some of yellow), Butterflies can see 5. This is taken further by the Shrimp Mantis which has 16 color receptors
I am fascinated by birds' color vision. They have four types of color cones, whereas humans have three. That means they can see a lot more color variations than we can. Also, a few years back on Science Friday they reported that birds see color in three dimensions. Whereas humans see color as solid and flat, birds might see objects as having one color overlayed on another. In other words, they see depth in color. This might begin to explain the mystery as to why birds can't see glass.
There are rare women with tetra-chromatic vision, who can see millions of colors. An artist showed her paintings of flowers, looking like the UV depictions beyond normal vision. She said, "I paint what I see."
you just blew my freakin mind, they can see layers of colors!?!
Some humans although rare have them too.
I am sure most birds can see glass, and some humans cannot see glass, if it is well polished, and their attention is elsewhere!!! :)
One of the prevailing theories as to why so many mammal species have such poor color vision is that for the tens of millions of years that dinosaurs dominated, most mammal species were small nocturnal animals and their eyes adapted to seeing low light, evolving more rods (which gather more light) than cones (which impart color vision). When the dinosaurs underwent their mass extinction, and mammals began to spread out into the newly vacated ecological niches, they were "stuck" with that more limited color vision (though superior night vision), unless they went on to re-evolve better color vision. It's speculated primates did that in order to better differentiate what kinds of fruits and other things were safe to eat, which was something more useful for strongly diurnal omnivores.
That's fascinating
I noticed a pattern of a lack of red. I guess there is something with the color that hinders night vision???
@@russellbrown7024 lol, ok captain obvious
It seems fruit eaters have better color vision, so they can distinguish ripe from unripe fruit. Primates, including humans, are such fruit eaters.
Another thing about cats is that the reflective surface in their eyes is behind the retina, so light entering the eye gets two passes, effectively making the world twice as bright for them.
Im glad to Be a human WHO can see. ☺️
We have one of the worst vision in animal world
I think there is a great deal of interpretation of sight that occurs in the brain. Consider our blind spot. We don't notice it because our brains "fills in" the spot. Various animals have abilities related to their vision and their brains make sense of the input.
👍
Respect for person who tried animals eyes
The eyes of cats and dogs are often beautiful 😍
If i had 360 degree vision and my eyes would move seperately, I'd probably spend the rest of my life puking.
I have squint and I can tell you it's not funny
0:45 I love how he stares at us😂
Would be cool to have infrared receptors in the retina. Seeing heat is very useful.
Yeah, but it would need to be a voluntary sense. Personally, I don't want to spend the rest of my life looking at the world with an infrared heat map laid over it whether I want to or not.
Thank you so much. You've made me upet about my cat's vision of the world. No wonder she prefers to sleep most of the time
And she's probably wondering why you're asleep during the best part of the day: night!
@@PeloquinDavid she sleeps neerby at night and wakes me up at 5 a.m. when she gets hungry :))
I got sad too about my cat!! 😢😢
I think they can see up to about orange but itll be dim. Do consider how much pity a bird or butterfly would have for our own vision, and perhaps what we have for blind humans.
"...I mean it's not 50, but still impressive" 😂
I wonder how popular a myth it is that cats and dogs are completely colour-blind.
Two things I noticed you don't mention:
* Depth perception. Many animals have their eyes on the sides of their heads; while this widens their field of vision compared with humans it comes at the expense of this.
* Mantis shrimps. These have 12 types of cone cells, so effectively a 12-dimensional colour space (compared with our 3-dimensional colour space). Apparently some kinds have as many as 16, and what's more they can see the polarisation of light.
It seems in recent years scientists have come to believe dogs and cats do see some colors, but cannot see red. An example sometimes given is the orange-striped tiger. The orange stripes look green to the tiger's prey, so they just think it's grass. For humans, the tiger is pretty obvious. Tiger prey must hear or smell the tiger to realize it is near.
They will absolutely see different colours and interpret red as something, but it wont be that noticable. Our vision covers a spectrum of combinations of RBG, whereas they only have BG: But BG will still intercept some red. Just not much and with difficulty. We can see orange wavelengths of light for example, but only because it overlaps with the red and green cones a bit. So RGB lights can trick you into seeing orange by stimulating the red and green sensors the same amount as they would be by orange light.
So i looked it up for humans: Our green receptor stops entirely at about 650 nm, which is actually red. So green cones CAN detect red, and so cats and dogs should be able to see some red, but it will be MUCH dimmer: 615nm which would be reddish orange would be 10% as bright as an equal source of green, and 630nm maybe 3% as bright.
That's amazing 😮
Having a 360° vision is just incredible!
It's 340 he said
@@neonranger1192he said fishes have an almost 360° vision.
@@nazimaahad4174 yeah cuz their eyes are on the sides
Nuff respect to the person who live all these different animals life to tell us all how they see the world
Informative video thanks a lot. I searched for this type of videos for a long time .
Explains a lot with cats and how they find everything so interesting. They are literally in their own world.
The idea that T.Rex could only see moving objects in Jurassic Park is actually explained in the novel as a trait dinosaurs got from their frog DNA.
Caws, my favorite farm animals! 😁
respect to the people who did this project
Thanks allot 🙏 I always wanted to know how animals sea the world , it is well explained in this video 👍
3:23 40 shades of grey 😂
The most impressive feature about cat's eyes is not that their pupil expand (after all, ours do too even though much less than theirs). It's that, unlike us, they can control them and decide when to expand them and do it instantly. We can't, our pupils simply expand and contract based on light conditions, and they take some time to do it too.
Jadni konji s takvim vidom😢, ali ja ih opet smatrsm dobrim i inteligentnim životinjama😊steta sto mnogi biljojedi kao konji, krave i ostale kao maca ili cuko ne vide dobro😢Volim zivotinje❤
Pit vipers have heat sensors. Not all snakes.
😮
Very nice! I love your content. ❤
Wow, so even though I try to swat a fly as quickly as possible, I'm actually slow in their eyes and that's why they fly away everytime
Plus they are the best at flying - scientists have been working hard to replicate their flight but so far we have not been able to - they can take off from a standing spot like a helicopter but fly like an airplane
I’m glad that various animals have also contributed to this video
Caws? Or cows.
Cows
My question is how do you know what these animals see' did you sit down and ask them
Thanks for increasing my knowledge. There are so many things to know. Ps tell me more.
💡🎇🌎🌍
More interesting question is would we go insane if we suddenly get hyperspectral vision from MWIR to UVC?
wonderful information.
Thank you so much.
now lets move on to ✨caws✨ 💀
i love that you try to make the world through animal eyes but yet i still see it how a human would see it through a simulation wich is supposed to be the animal
Humans have made educated inferences about how animals see the world by combining several methods and lines of research. Here are some ways through which we've gleaned insights into the visual world of animals:
1. **Anatomy and Histology**: Dissecting and examining the eyes of animals gives insight into their visual capabilities. The number and types of photoreceptor cells (like rods and cones in humans) can suggest what kind of light the animal can detect and how well.
2. **Behavioral Experiments**: Scientists can train animals to respond to visual cues. For example, bees can be trained to associate certain colors or patterns with food. By altering these cues, researchers can deduce what colors or patterns bees can distinguish.
3. **Molecular and Genetic Methods**: Studying the genes responsible for vision can reveal what wavelengths an animal can perceive. For instance, the opsins in photoreceptor cells are sensitive to specific wavelengths of light.
4. **Electrophysiological Techniques**: Electrodes can be placed in an animal's visual system (like the retina or visual cortex) to record electrical responses to visual stimuli. This can reveal what kind of light stimuli the animal is sensitive to.
5. **Comparative Studies**: Comparing the eyes of animals who live in similar environments or have similar lifestyles can give clues about their visual capabilities.
6. **Physical and Optical Models**: Scientists can use models to simulate how light enters the animal's eye and is processed, giving a representation of what their world might look like.
7. **Direct Imaging**: For some species, specially designed cameras can mimic the visual perspective of the animal. While this doesn't perfectly capture the animal's subjective experience, it can give a hint of their visual field and focus.
While these methods provide a lot of information about the visual capabilities of animals, it's crucial to remember that the actual "experience" of seeing as an animal is something humans can't fully grasp. We can only make educated approximations about their perceptual world.
THe ultraviolet part is quite interesting for birds as crows and ravens are not black through their eyes and have some interesting paterns of feathers.
Fun fact - two big difference of visions between man and cat shows in thumbnail. But thumbnail itself is dog.
“If you’re ever sneaking up on a cow, make sure you give them a heads up.”
🤔💥🧠💥🤯
The chameleon’s vision is impressive
How many animals eyes has been personally tested to know that this is what they see rather than assume
Scientists seem to think with their arrogance that they know everything.
Flies only see in "slow-motion" relative to human vision. They don't actually perceive time as being "slowed down," no more than we perceive time to be "sped up." From the fly's perspective, time passes normally and the rest of us are just really slow at moving.
I loved your perception! 🧡
I think you get the same effect watching 30 fps vs 60 fps on your phone. You can physically process more information.
@@OsirusHandle ??
30 fps on your phone is the same as 30 fps on your TV or monitor. The device wouldn't make any difference.
@@sixstanger00 i said 30 fps vs 60 fps
@@OsirusHandle No, that's not how a fly's perception works. The fly isn't "processing more information," it's just processing the same information at a much slower rate compared to a human.
But the fly doesn't perceive anything as "slow." From it's frame of reference, everything is moving at normal speed and humans seem to just move painfully slow.
Likewise, from the human's frame of reference, everything seems to be moving at "normal speed," and the fly just moves exceptionally fast.
Cows blue and green vision seems so soothing
*I want to become a cat*
6 times better vision in the dark compared to humans....😂
Cats have shorter lifespan than humans
Yes finally thank you for this vid!
I like how fish get to see red unlike dogs and cats though they never encounter it.
Chameleon eyes: we are independent!! Long live the king
You have missed an important one😅... Dragon Fly has compound eyes and they can see the largest number of colour shades than any other living things can see... It's cool .... isn't it? So you missed out the interesting one!!
Laughs in Mantis Shrimp
@@Roachrancher 😆😆👍
سبحان الله العظيم ❤
How did Everything is made perfect our eye and others , the bird one was mind blowing
Thank you very much for this perfect video ♡
Nice video. However, I'm confused about the cows vision as stated. If they can't see red, why do they use red flags in the rodeo arena to distract them?
Its not the color that upsets the bull. Its the motion of the flag itself
@@davidford4660 Wow! Thanks for clearing that up for me. Have a great day. 🤗
How did they know cows can’t see red?
@@abhuju22 they have no red receptor cells in their retina.
@@abhuju22they do experiments and compare animal behavior (usually with colored feeders). Look at Karl Frisch book about bees. There he explains how he did experiments to test bees sense of smell, color, etc. he discovered and decided bee language!
What if we humans see colors different? What I see green, appears red to someone else. We would never know
Because you learn the color "green" as a kid - but I see it what i call green, and you see it what I would call "blue".
Its a interesting topic and if you think about it, you'll find out, that you can never say to 100% that you probably see a green tree, what appears blue to someone else
Experiments show animal x can distinguish color y from color z. How they actually look inside their brain we do not know!
Thank you for the video, loved it ❤
I’m pretty sure they found out how the frog sees things because the princess was there to ask it!
First video from BRIGHTSIDE That is actually educational.
huh
How do you know what animal's vision is like?
Your videos are so inspiring to us small channels. Wow ❤
Do animals that can see uv use it all the time? Or they switch the "uv feature" on and off as needed?
yes
i like the channel content very much
What if the world is green like cows see but poor humans can see it as multicolor
The topic I was looking for, I couldn't find a video about this topic for a long time, thanks.😊
Thank You for Informative Video
What I want to know is, how do we really know this? It can only really be a guess as to how they actually see things. Just because they don't have the same receptor as us, doesn't mean they can't see. We are projecting human anatomy on animals. Maybe they don't NEED these receptors to see all colors.
most of it is via dissection in a laboratory 😮
Interesting 👏👏👏
This eye vision concept totally guess dependent🙃. Nowadays technology touches higher level but some things doesn’t solve those technology. An example eye vision for different animals
The animal with the most color differentiation is the mantis shrimp with 12-16 different colour photoreceptors for colour analysis in their retinas. Look these animals up for other fabulous facts
I guess there are many colours that humans do not vision it 😁🤔🤔🤔🤔
Do we human beings see all the colors or do we miss any color in this universe?? Like other animals and birds do...
Object colors are defined by the light (electromagnetic waves) it reflects. The electromagnetic spectrum is pretty wide, visible light is just a narrow part of it.
There are colours we humans can't see. There is a certain trick to see some of these colours, it's on youtube somewhere.
Humans can’t see ultraviolet and infrared. Some birds and most of insects see ultraviolet (flowers often have UV features for bees). Snakes often see infrared (like human designed infrared night vision devices :)
Cats can’t see the stars I’m pretty sure. Great vision with 130 degrees binocular vision, 287 degrees total, but they lack distance.
Would’ve been cool to see the alligator, they see through swamp water.
I’m assuming the colors are off but the highlights are the main focus.
We represent UV/IF with certain colors, the animal might see it like an added detail or a mirage-effect.
We know how eyes work, but scientists aren’t artists
I totally disagree about the vision of dogs, because I did an experiment myself on that theory with my neighbor's dog ...
👁️✍️🐶
And what did you discover?
@@vladislavdimitrov4646 Dogs are able to recognize all colors, especially fluorescent or brighter.
How?
Doesn’t see color means not it’s blind, but dog will confuse some colors as one. About proper method how animals are tested I recommend book by Karl Frisch about bees. You will know how those experiments are designed. Insects were tested! 😀
And women see the world in the color green.
Very helpfull information
Thankyou for uploading
Now i know why I always miss those flies with my hands...
I'm ok with what I have..tnx
who asked?
Flies see everything in slow mo, now this explains everything 😂😂
What about hedgehog vision? From what I understand, they see blue, yellow, and shades of grey. But they can focus on objects 3 or less meters away from them. Beyond that, everything becomes blurry, and they have to rely on their smell and hearing.
---> 2:53 this is my favorite part also I have a lot of favorite parts hehe
I would try to find a way to rule the world
Just with ya eyes?
I had be dizzy
Nice
Looking forward to more creatures
Wow amazing! Thank you I learn something new today. 😊😊
Thanks to ALLAH
Made everything,which human can't ever understand.
SUBHAN ALLAH
The Almighty is far away creative beyond our imagination
So much wrong in this video...I don't even...
What do you know?
How can a fly see in slow motion
If this is wrong you ruined my childhood 😭😭😭😭😭😭😭😭
Amazing!!😍
Man this gives me hope.... I adopted two stray cats last week and they're still so shy and withdrawn. I hope with patience and love we can get the same results eventually.
First (ik no one cares)
no one cares😢
Dude ur 1st
I think that humas also cannot see the real colour of earth. Allah know it only.
The thing is that human eyes can focus spectacularly in very small and short distances. Reading for example relies on that feature.
How did you know that? But I like the of the bird! 😁
Pin me if I tricked you.
Read more....
Lol u tricked me
I seen this comment 6 months later and I tricked myself 🤣🤣🤣
I was wearing headphones and the cat sound scared tf out of me had me looking around 😂😂
That’s why flies dodge my hand everytime because it’s coming in slow motion
Biggup to the animals that explained the colours they see to humans,they made this video possible💯🫡
Very interesting, im glad i clicked on this video🤩
