00:00You know that animals see the world differently from us?

00:03Let's take this example.

00:04The pigeons have in fact a better view than humans.

00:07It's funny, right?

00:08So, let's try to see the world through the eyes of some animals.

00:11Let's start with the serpent.

00:13Their way of seeing the world is totally different from ours.

00:16They have special receptors sensibles to infrarouges in their museus.

00:19This allows them to perceive the heat emitted by the mammals to show.

00:23Now, let's go to the vaches.

00:25These big birds don't see the colors as well as humans.

00:28They are incapable of perceiving the red color,

00:30because they don't have the receptors necessary in their retina.

00:33They perceive so only variations of blue and blue.

00:36Plus, they don't like when someone approached them from behind.

00:40Their vision is almost panoramic,

00:42and the only zone that they can't see directly,

00:44it's the rear of their head.

00:46So, if you ever have a vache,

00:48assure you to see it.

00:50The chevaux have an angle mort just in front of their face,

00:53because of the position of their eyes.

00:55This means that they can't see the things directly in front of them.

00:59In addition, they don't see the colors as we.

01:01Like the vaches,

01:02their world is mainly composed of red,

01:04jaune, and blue.

01:06Pauvre bête.

01:07The eyes of the poissons have a receptor ultraviolet

01:09and of a lentiless more arrondi than the other.

01:12This gives them a vision to almost 360 degrees.

01:15In terms of the colors,

01:16they are able to see the same as we.

01:18They are the same as we.

01:19But since the light is different from the air,

01:21they have a problem to distinguish the blue and its nuances.

01:24The poissons of the profondeur

01:25can easily see in the dark,

01:27which is extremely useful.

01:29The requins, on the other hand,

01:30can't distinguish at all the colors,

01:32but they see much more clearly from the air that we.

01:35The oiseaux have a fairly unique way to see the world.

01:38Contrairement to humans,

01:39they can distinguish the ultraviolet.

01:41This helps them to differentiate

01:43the males and females of their own species,

01:45as well as they can see in their environment.

01:47In addition,

01:48they are also very proud to be focused.

01:50Ainsi,

01:51the poissons and the aigle

01:52can concentrate on a small souris

01:54in a distance to a distance of more than 1 km.

01:56A pigeon can see all sorts of details.

01:59So,

02:00if you need to see a fissure in the trottoir,

02:02ask simply to a pigeon.

02:04And in fact,

02:05they have a vision of 340 degrees.

02:07And in general,

02:08their view is considered

02:10as two times more affine than humans.

02:12And here,

02:13I am just a pigeon.

02:14The insects have also

02:15some kind of perception

02:16quite strange.

02:17The mouches,

02:18for example,

02:19have thousands of little receptors

02:20oculaires

02:21who work to concert

02:22to give a global vision

02:24of what happens around them.

02:25And devine what ?

02:26They distinguish all at the ralentis.

02:28In addition,

02:29they can also see the ultraviolet light

02:30which helps them to communicate.

02:32The abeys

02:33have their own problems.

02:34These little creatures

02:35are incapable

02:36of recognize the red color.

02:37For them,

02:38it looks just like

02:39a blue blue.

02:40It's funny,

02:41or not?

02:42These little guys

02:43can't even see the red color.

02:44But it's not

02:45the most strange part.

02:46Each one of their eyes

02:47can't be seen

02:48independently,

02:49so they can see double

02:50all the time.

02:51It's amazing

02:52that they don't often

02:53see the murs,

02:54isn't it?

02:55They don't perceive

02:56the red color

02:57or red.

02:58But they distinguish

02:59the brown,

03:00yellow,

03:01yellow and blue

03:02as a pro.

03:03They have a great angle

03:04so that they have

03:05a better peripheral vision

03:06than the other.

03:07And there's more.

03:08When it's completely dark

03:09out,

03:10they turn into a ninja

03:11and see up to six times

03:12better than us.

03:13Their pupilles

03:14adapt to any kind of luminosity

03:15like magic.

03:16Now,

03:17let's talk a little bit about the chiens.

03:18Nos compagnons à fourrure

03:19ne peuvent pas voir

03:20le rouge ni l'orange,

03:21mais ils excellent

03:22dans le bleu et le violet.

03:23Par ailleurs,

03:24ils peuvent différencier

03:25jusqu'à 40 nuances de gris.

03:27Bon, ça n'en fait pas 50,

03:28mais c'est quand même impressionnant.

03:29De leur côté,

03:30les grenouilles

03:31sont vraiment difficiles

03:32en matière de nourriture.

03:33Elles ne s'embarrassent pas

03:34avec des proies immobiles.

03:35Elles pourraient être entourées

03:36d'un buffet de délicieux insectes,

03:38mais si tout ça ne remue pas,

03:39les grenouilles

03:40ne s'en préoccuperont même pas.

03:41Et elles ne sont pas

03:42les plus fines observatrices non plus.

03:44Si quelque chose semble

03:45sans intérêt pour elles,

03:48ils ne se donneront même pas la peine de regarder.

03:50Les caméléons ont des yeux

03:51qui peuvent bouger

03:52indépendamment l'un de l'autre.

03:53Ils peuvent donc voir

03:54tout ce qui les entoure

03:55sans même tourner la tête.

03:57Ils sont même capables

03:58de voir deux images en même temps,

03:59comme regarder deux films différents

04:01côte à côte.

04:02Plutôt balèze, non ?

04:03Et toi ?

04:04Que ferais-tu si tu avais

04:05tout à coup une vision

04:06à 360 degrés comme un caméléon ?
