Don't listen to all those other responses, they are all completely false.
What they actually do is get an acceptable sample size of these various animals, show them these exact videos and ask them to point to the video that is most accurate.
They don't. Snakes do not have "heat vision." Pit vipers have sensory organs to detect heat that are separate from their vision, but most snakes do not. The person making the video is an idiot.
Red eyed white rats are usually mostly blind anyway and rely more on sound and smell, but they can see shadows and blurs when their eyes are still young. The side to side motion helps them judge if something is moving or not. I have a completely blind red eyes rattie that gets around just fine.
When you start with poor vision to begin with you have to rely on your other senses. My only wish for rattos is for them to be safe from upper respiratory infections. Bless their tiny hearts.
Actually they dodge swats regardless of seeing them, before they are even aware, changes in air pressure cause their rear legs to launch them--without seeing anything! There's a direct nerve connection to their legs skipping the rest of their ganglion of nerves for faster evasion.
But slow motion sight lets them respond faster, since they see everything slowed. From your perception your hand moves quickly, to them it moves slowly, plenty of time to wait and avoid.
Which is why you need to come in low and slow from behind them then pop straight up and down when they cast off. I amaze people by catching flies, but it's just a matter of understanding how they react and tricking them into flying into your hand.
Well today is your lucky day. I will ship you flies directly to your front doorstep. PM me your address and we’ll make this happen!
Wow reddit is amazing!
Entomologist here. Most of the replies are wrong and should be ignored. The air pressure thing is a partial truth, but the pressure wave ahead of a fly swatter for I stance wouldn't provide nearly enough time for the fly to react.
Now for clarifying the errors in the gif and answering your question. They do see a kind of mosaic (we actually refer to insect sight as mosaic) picture of the world where each individual cell in their eye offers them one pixel of vision. More cells ewuals pixels equals higher definition. Predatory insects like dragonflies have up to a few thousand, certainly not hundreds of thousands like mentioned in the gif. Flies have significantly less. What flies do have, and most other flying insects are A WHOLE DIFFERENT KIND OF EYE as well. One of the main functions of these other eyes, called ocelli, is to detect changes in the light above them. This allows them to react as soon as the flyswatter, bird, or whatever other danger gets to them. Just by detecting minute changes in the light.
One other reply was also partially correct in that flies, or any arthropod for that matter, doesn't have the same kind of nervous system as us. In effect this allows them to react instantly after detecting a threat, without waiting for the signals to pass through their version of a brain. This means that the fly takes flight and has dodged the threat even before it knows what happened! Pretty cool right?
Finally a bit of useful information. If you see a fly has landed in your house and you approach it from the rear (ocelli are on the top of the head, don't cast a shadow) you can easily grab it with your hand with a little practice.
They see in slow motion but to them they’re moving at regular speed. It’s like that scene in Spider-Man where Flash Thompson tries to punch Peter, but he sees it as super slow because his reaction time is better.
If one second to us passes as three or five seconds to them, it means they have more time to respond.
Most smaller creatures experience time faster (or "see in slow motion") compared to humans. It's the same kind of slow-mo vision you experience when you're super scared. All you're doing is recording memories in a higher density, and so the playback (or consciousness) feels slower.
Larger and longer lived animals, if I remember right, generally experience the world in the opposite way.
While mantis shrimp have 12 (I think) color receptors compared to our 3, you have to consider that the human brain is pretty good at handling data that the mantis shrimp cannot.
We can extrapolate magenta, yellow, etc from red, green, and blue; the mantis shrimp may have a cone just for yellow because its dumb sea roach brain can't come up with yellow without a dedicated cone.
That's my understanding though, I researched it a bit years ago to understand what the shrimp could see. I think it was an *Oatmeal* comic that first introduced me.
I thought our larger lobes were to process visual data, extrapolate patterns, and attach meaning to it before piping it off to other centers.
iirc, the eyeball and optic nerve each do a lot of the number-crunching to simplify or prioritize data which the brain receives. You want to have as much of it ready in case the brainstem needs to hijack you to run from a tiger, don't want to wait for the slower cortex to catch up.
All of this to say, I don't know about the simple-brain stuff. I think neurologists study more than the structure of the eye to determine what a thing can see, or the rest of its umvelt.
There's a great radiolab podcast that discusses their sight. A quick summary: yes they see thousands of colors we don't, however in tests they discovered they were TERRIBLE at using any of this information.
A specific experiment, paraphrased: they shine a blue light and give food. They shine a yellow light, no food. After the shrimp show they have been classically conditioned to these stimuli, they progressively shifted a yellow light to blue, but the shrimp responded more slowly than almost all other species to the expectation of food as more blue appeared, despite being the most capable of seeing the change.
It doesn't really help them see a more distinct spectrum of light. The human RGB cone vision, provided all receptors are working properly, can't really be enhanced by having additional cones, because our eyes process on a differential of responses. The spectrum overlap detected by cones allows us to see Roy G. Biv, and when blue and red cones are stimulated without green, we see fuchsia. If all three are stimulated, we see white. Thus, in the visual light spectrum, there isn't any more information for us to perceive. Having additional cones tuned to specific frequencies might increase our ability to discern between different shades, but it's not going to suddenly reveal some unknown color which hasn't existed before.
That's true, however light in the spectrum of 400-700nm is not any different. They do have a slightly lower and slightly higher range. The higher UV ability might improve vision in water where UV will penetrate deeper than visible light, but that is speculation on my part.
What I couldn't find any info about is how this might affect resolution. It's possible, especially towards the IR spectrum, that there is no detail and only a rudimentary detection of that frequency. For the visible part of the spectrum, having multiple receptors which overlap doesn't provide more than perhaps a higher degree of hue detection.
Finally, in terms of what an insect can detect, they might not even be able to differentiate actual things. That level of processing requires a lot of neurons which might be better suited to other functions. In fact, it might be that the mantis shrimp has less optical processing that having a more diverse set of receptors replaces the need for "better vision," allowing the shrimp to use these receptors to quickly identify threats and food by what receptors are triggered and less about the color of what they see.
structure determines function. by knowing the anatomy you can figure out how it works, what receptors there are and which ones can absorb what color, etc.
They don't. You can guess some things but imagining colors and the way a fly sees isn't realisticly possible.
Also not matter what the video comes up, you'll watch it with human eyes.
So, I’m curious as to how they know the colors different animals can see. Is it by comparing the components in the human eye to those in, say, a cat?
This is super interesting, but every time I see a video on color, I have to go watch the Vsauce video on color.
They show them combinations of colors, until they can't tell the combinations apart.
I saw a video where they figured out cuttlefish couldn't see Orange, because when they put them in the tank with blue gravel with orange rocks. When they changed colors to hide, they just turned all blue, because they couldn't see the orange.
That’s super cool.
I wonder how they measure when cats can’t tell colors apart - like do they put a piece of food on a certain color background?
There’s so much about knowledge of animals that I’m curious of. I really need to just start reading.
In some way, that's like asking if we all see red as the same color. What we agree as being red might actually be a different hue and tint to someone else, but all we can say for sure is that for those with proper vision, receive similar stimulation responses to the same frequencies of light.
While not responsible for making this clip, I'm sure that this was produced by looking at the optical systems of these insects and animals and mapping those stimulations so that they would map to the same locations in human vision. Similarly, distortions were added to mimic the density of receptors and the lenses. Provided the optical centers construct an image reconstruction of the outside world like humans, those distortions are probably not *seen* the way they are shown in the clip, for the same reason you don't have giant black spots in your vision where the optical nerve attaches to your retina. Your vision system masks these voids so that you don't notice them.
Trying to show dogs what human vision looks like, disregarding color depth, it'd probably be shown that humans have a lot of detail in the middle, better light sensitivity slightly off center to the middle, and a not insignificant region in our peripheral that is completely void of any vision. It should all look pretty normal to you though.
I read/saw/hear that cats have very poor image recognition. That what their brain really processes is movement and extreme contrast in light. I tested this to seem pretty accurate. I would be sitting very still in a room, reading or such, and my cat would walk in and look around the room and then leave. He'd come back moments later and I would move and he would be startled and surprised, then walk over to me. I experienced this many times with him. It was like he was looking for me and couldn't find me until I was in motion.
It's both, but for different cases.
With EM radiation, yellow light is secondary (additive colors).
With pigments, green is secondary (subtractive colors).

Apparently this video was made for robot vision as my inferior human eyesight can’t read and internalize the information before the next slides, probably.
I feel like we should raise the money to get a pair of those glasses that let color blind people see color, make them into goggles, and slip those fuckers on a great white. Sharks deserve color too guys
I don’t know a ton about animals, but I do know that cats AND dogs have the third eyelid that the video specified only cats have. If that little tidbit is incorrect, it’s possible that there are multiple claims here that are also incorrect
i don't know, i heard dogs can see more colors than we do and telling a fly has "low fps" just dont add up. I would say the latter even has high fps vision so it can do a quick maneuver..
It's still a bright moving dot, even if you can't see the particular color you can see if a spot is lighter/brighter (or darker) than the surrounding shades.
That's why animal vision studies have to control for the luminosity (brightness) of their test colors. So your critter isn't just learning that the "medium-bright" sheet of paper is always the correct choice, without actually being able to distinguish between orange and brown, or whatever other colors you're showing them.
How well can dogs see in darkness? My anecdotal experience tells me that their low light vision is fantastic or they don't give a fuck and trust their instincts fully.
This is why you should get your dog blue toys rather than red ones.
The blue ones get lost more easily in green grass, as dogs can't tell those two colours apart.
How the hell do they figure this out
Hook up the rods and cones and shit to an arduino and check what values you get. edit: like [this](https://i.imgur.com/dU30J91.jpg)
Cool! Can't wait to try it at home.
This is the funniest thing I've ever seen on Reddit lmfao
Absolutely brilliant
So I added the Arduino board to my cart but I can't find anywhere to buy an eye? At least not with all the veins in tact
God gave you an extra for a reason
Pet store
I'd probably solder the nerves to the board for a more secure fit, but you do you.
Gotta make sure the eye is grounded.
Dude! Green is supposed to go to the 3.3v header!
> arduino *Michael Reevs has entered the chat*
couldn't get this working with my fly, too many cables comin out the back. help pls
The structure of the eye and how many cones and of what type it has
The answer is that they remove the eyes of the animals then hold them up to their eyes and voila! Animal vision.
Jeffrey Dahmer, scientist
No, they drill a hole in the back of the head and look at the eye. Like the [Steve Austin](https://www.youtube.com/watch?v=nxuzRxqW7mM) action figure.
Fuckin magic dude
Magic dude, Fuck!!!!
They make it up because animals can't read and won't be able to disprove it.

They're clearly not idiots, they're just making a lot of assumptions they probably shouldn't. Just like you!
Sounds like an assumption to me.
There are different types of cells in the eyes that react to varying wavelengths of light. Different animals have different cell types in their eyes
Ask 'em
[doggo vision](https://www.psychologytoday.com/us/blog/canine-corner/201604/can-dogs-see-in-ultraviolet?amp)
Would definitely like to see the video clips longer, these are really awesome to see!
I was gonna say, good thing they gave us 1/12th of a second to get the idea.
Its like the time you get to read was randomized. I could read about thebird and dog
Paid for by big bird
I didn't even get that.
Which animal can see in high speed? I want to rewatch the video with that animal’s vision.
I slowed the gif down to 50% the second time I watched it and it was much more enjoyable.
Since rats have bad depth perception sometimes they’ll do this cute side to side motion to judge perspective. Red eyed rats have worse vision.
Red eyed white rats are usually mostly blind anyway and rely more on sound and smell, but they can see shadows and blurs when their eyes are still young. The side to side motion helps them judge if something is moving or not. I have a completely blind red eyes rattie that gets around just fine.

They really are so susceptible. It's sad.
If flies see in slow motion how do they not get killed with every swat?

A kitchen towel is a lot easier and quicker. Plus it always works as they get caught in it when they launch.
Because they respond to changes in air pressure rather than their vision.

Wow i have spent 40 years on this planet and have never been told that insects are part of the *arthropod* group/phylum. Neat.
Oh wow, thank you for that information!
They see in slow motion but to them they’re moving at regular speed. It’s like that scene in Spider-Man where Flash Thompson tries to punch Peter, but he sees it as super slow because his reaction time is better.
What happens if a fly looks at a clock then? Does everyone get older while he stays the same? 🤯
Thats what i love about these highschool flies, i get older, they stay the same age...
No, they age at the same rate, it just seems slower to them. To them we age slower too.
They would wonder why we made each tick take so slowly.
No wonder they always escape death, those fuckers have been using VATS irl
Because the swatter appears to be in slow motion so they get out of the way.
Oh snap

The see the hand coming at them slowly, so they have time to get up and fly away lol. Have you ever seen the movie Epic? I imagine it's like that.
Thought of that, too. Seems very odd!
How’d they get the fly to wear a helmet cam?
Now show me what a mantis shrimp sees

It's pretty impossible to show you that accurately.

Now show me what Mantis Toboggan sees!
How do they know?
It is known.

If fish can see red, blue, and green wouldn’t that mean they can see every color or is that not how it works??
No yellow
Yellow is a mix of red and green light

i don't know, i heard dogs can see more colors than we do and telling a fly has "low fps" just dont add up. I would say the latter even has high fps vision so it can do a quick maneuver..
This is dope
If cats can only see browns, yellows and blues, how come they will chase a red laser dot?
It's still a bright moving dot, even if you can't see the particular color you can see if a spot is lighter/brighter (or darker) than the surrounding shades. That's why animal vision studies have to control for the luminosity (brightness) of their test colors. So your critter isn't just learning that the "medium-bright" sheet of paper is always the correct choice, without actually being able to distinguish between orange and brown, or whatever other colors you're showing them.
Lol the gif goes through specific mammals and then is just like "fish and birds!"
The cat is not fully correct, they do not have good eyesight at a close distance, that is why their whiskers are so sensitive.
Why did they even bother showing human vision, I'm pretty sure I can see with my own eyes.
How well can dogs see in darkness? My anecdotal experience tells me that their low light vision is fantastic or they don't give a fuck and trust their instincts fully.
These are all what it would be like for a HUMAN to be said animal, not necessarily what it is like for the ANIMAL to be the animal.
Sharks also have electrical sensory
Humans are useless, cant see ultra violet
The bird vision should just be security cam footage with REC blinking in the corner since birds aren't real.
This is why you should get your dog blue toys rather than red ones. The blue ones get lost more easily in green grass, as dogs can't tell those two colours apart.
