How does animals see the world ?

 today we're gonna be looking at how

10 different animals see so we're used

to see the world through our eyes but

most animals are completely different

eyes and see the world totally

going to allow you guys to see the world

through the eyes of 10 different animals

i'll try to apply to all of you

so coming in at number 10 that we have

dogs so he wouldn't have five color

codes in their eyes and these codes

divided up into four primary colors

which are red green blue and yellow but

dogs only see blue and yellow so

compared to humans also be colorblind

and that's why they have such a good

sense of smell because it is so weak

and if you guys can't see the ? in this

the image then you have eyes like a dog

because they wouldn't be able to either

because they wouldn't be able to tell

the difference between red and green and

it's a popular myth the dog fancy color

at all and see things in black and white

but no they're partially colorblind but

they can see some colors another weird

the thing about dogs vision is that they

could only see at 60 degrees what's in

front of them what humans concealers 140

degrees in front of them and if you know

if you put something really close your

eyes and then it gets all blurry

well dogs don't have that and I kinfolk

some things are very close to the but

not as far away as the human eye but

coming up next we have sat so we all

know that only come out at night and

because of that, they have a bad vision but

their vision is 110 times brighter than

a human vision so they can see in the dark

more easily division they do have it's

like thermal night vision but they

mainly rely on high-pitched noises that

a lot of bats put out to get around and

to communicate their ideas polarized

light switch our light waves that are

parallel to each other and vibrate in a

single pain but yeah that has a red

Center vision to see thermally and they

sometimes also seen a regular light vision

mode when they're not looking for prey

to eat but next up we have been so like

dogs so have all of the colors

receptors for the four primary colors

are the ones they do have a blue and

green but not yellow and red but they

can also see the UV spectrum meaning

they can actually see UV lighting that

humans cars and obviously because

because of these certain colors of AC

plants and flowers very differently have

compared to humans but they can also see

things that are invisible to us such as

ultraviolet light patterns in the center

of plants and flowers and this can help

be determined for wants to take the

pollen and nectar from a certain flower

or not because they can see UV lighting

which

just color depending on the certain type

and quantity of pollen and nectar so it

basically, use the ultraviolet light

seeing the ability to take them to the clubs

with the most nectar and pollen so they

can make more money for us to eat but

next up we have sharp so you know when

you go into the water and open your eyes

it goes all blurry and then you can

really see anything until you come up

again well sharks complete clearly

underwater just like how we see when

we're not in water and sharks see all in

black and white and that allows them to

see clear contrast in lightness and

darkness as we all know that when you go

down to the bottom of the ocean, it can

be dark and also in the ocean that

there's a lot of areas with murky waters

well sharkskin seems dark murky water

because they have something called the

tapetum do dis year which is the layer

of marriage crystals located behind the

retina the next up we have bird so good

size of a lot differently humanized but

they're also very cool so in a

bird's-eye distance or whatever they're

looking at is magnified because they're

I muscles focus on certain places but

also have four silicones in the eyes

called photoreceptors while humans only

have 2 I'm this allows them to see

ultraviolet lights kind of like a bee

add another crazy thing about good

vision is that the considers magnetic

the field which is now able to migrate to

hot countries in the winter and the

Earth's magnetic field would look like

this to a bird once trips that move

right list than anywhere else

12s all very impressive but at least I

don't crash into windows and a regular

basis the next up we have rat so you

might not think the rats are the most

interesting animals subdivision is

pretty cool

that's actually seen with both eyes

separately and then the views of the two

hours to put together and was really

creepy each I can move independently so

what I might be looking up for the other

could be looking down or what I could be

looking left while the other is looking

right and right saucy things in slow

a motion so that they can focus on the

detail of thing because the rice is a

very slow compared to the human side and

rats or so color blind to the color red

but that doesn't matter too much because

they can't see that many other colors

anyway because the rise has a blue tint

which allows them to see at night and in

dark places but next up we have flown so

if you look closely it supplies I you'll

see it has thousands of small circles

making of its size and these are

actually, the Flies lenses which a

marriage onto their vision so they can

actually, see the same thing at many

times and fly to the north with the

ultraviolet light and I've already

explained how that works

also like rats like conceding slow

motion to help them focus on certain

things but that's actually not a good

the thing to them because it makes it easier

for them to get sorted by us while just

imagine how much more annoying maybe if

they saw things at regular speed the

next up we have snakes so we look at

snakes recently she has their eyes

activists me stereotypes they can see

some color but at night they can see

infrared because they have incredibly

sensitive infrared sensors located on

their heads and this can be used to see

where heat is so if they can sneak up on

their prey at night and killed

immediately as they can also export

humans the light with this so if you go

out for a peaceful stroll one night just

be sure to attract make my next up we

have fish so fish could only see red

green and blue meaning they have a very

limited color spectrum and that so that

they can see in the dark murky waters

deep down in the seat was that lack of

colors are only really needed for ocean

fish you go down into dark mocha water

but the house fish that you guys might

have a pet also see like this which is

pretty pointless because they don't even

live in dark murky water well in the

supposedly Winston doesn't clean out the

a tax that officials to see a much wider

angle and humans which is where the term

fisheye comes from and fish also have

ultraviolet light receptors inside their

eyes which allow them to see UV light

damn it seems like almost every animal

on this list concealed for violet light

but next up we have cats so the first we

think about a cat I just that they have

an inter-island inside there I which

gives them extra protection against

things getting the rise and cats only

see yellow Strauss and blues and that's

because cats have many more votes than

humans do which allows them to seems dim

light but the human retina also has more

cones especially in the area of the

phobia which is all codes are no roads

at all have this allows us to see bright

vibrant things in the sunlight sluts

attached all of the colors straight out

and it looks left happy and bright and

it's also a lot more blurry the

high-resolution you're used to seeing so

if you had cat vision it would be like

everything is permanently out of focus

and Captain goes a lot wider than human

because cats have a visual field that

spans the massive 200 degrees compared

to the 180-degree visuals found that

humans have so you guys would you rather

see in the dark like a cat's all have
