Description

In this video, we'll show you how animals see the world. Animals such as Dogs, Cats, Sharks, Snakes, Horses, Lizards, Fish, etc. These animal visions are based on Scientific Studies.





How animals see the world is much different than you might think.

For example, horses have their eyes positioned on both sides of their heads. This creates a wide field of vision that allows them to escape predators. But it also gives them a disadvantage. They cant see whats right in front of them. Also, they see fewer colors than humans do. They see the world mainly in yellow, gray and blue colors.

Snakes
Oddly enough, snakes are another animal that cannot see some colors. This has to do with the rod cells in their retina. Some snakes like Boas and pythons have pit organs on their faces that allow them detect infrared radiation from warm bodies. This lets them stalk their prey by sensing heat sources.

Birds
Birds can see ultraviolet light and have what is called an avian eye. They can change the shape of their eye lens rapidly. Birds of prey have an almost binocular-like vision. Eagles can see up to a distance of one mile. Their eyes are like a magnifying glass.
Oddly enough though, sparrows see the world through pink-colored glasses. They are unable to differentiate blue and green colors.


Rat
Rats vision is very blurry. They cant see the red color. Rats also see everything in slow-motion. Each of their eyes can move independently. This help them have two images at the same time.

Cats
Cats see the world even more different than other animals.
And wait until you hear what we have to tell you about the vision of dogs.
Indoor cats are nearsighted. They may only recognize you within a few feet.
Oddly enough, cats are also sort of color-blind. Which means they can see only some colors - or see in shades of grey. In particular, the color red confuses them.
However, cats do have the unique ability to see in the dark. This is due to the high number of photoreceptor cells in their retinas.

Insects
insects eyes generally consist of thousands of tiny lenses and receptors that collectively produce a wide vision. Insects can see ultraviolet light and see everything in slow motion.
A study from the University of Sheffield in the UK has revealed that insects can capture high-resolution images. In effect, insects probably have the best eyesight in the animal kingdom.
Butterflies have the best eyesight in the insect world.
Interestingly enough though, bees cant distinguish red or pink colors.


Fish
Fish can see clearly in any type of natural water because their eyes adapt to any available light source. Their eyes are also larger to their body size than other animals - so that more light can be refracted from their lenses.
Some fish have a second eyelid that helps them swim at a faster speed without damaging their corneas.
Fish can see in full color.
Sharks are not able to differentiate colors at all.


Cows

Cows dont see colors as clear as humans do. They see the world in orange and red. But they have something called a panoramic vision. Interestingly enough, it means they can see the entire world without even turning their heads.

Mice
Just like cats, Mice can also not see the color red well. Mice are also near-sighted. They can only see objects that might be about two or three feet away. So they use their whiskers to navigate their way around. This is why they are so good at finding their way around in the dark.


Lets look at how dogs see the world.

Dogs
Dogs vision is most similar to a human with red-orange color blindness. Interestingly, dogs can distinguish forty shades of gray. Dogs are also about half as sensitive to changes in brightness.
Dogs are most likely to notice motion from a long distance. This is more than 10 to 20 times that humans can sense. But this is also why you may wind up chasing them down in if they run after a faraway squirrel or a car.


Frog
Frogs can see only moving objects. They can starve to death if their food doesnt move. Interestingly, they can also focus only on objects that they want to see clearly. Frogs have excellent night vision.
Frogs also have bulging eyes. What this means is that they can see from both sides, directly in front of them, and even from partially behind.
But heres the most amazing fact about a frogs vision. They pull their mouth over their eyes when they swallow food.


Lizards
lizards can perceive color because they have multicolored droplets of oil in their photoreceptors. What this means is that they can see a wider UV range than humans can.
Lizards also have smaller eyes than other animals. But oddly enough, they have a larger lens, aperture, cornea, and pupillary for animals of their size. This is what allows them to gather light when they need to see at night.

Some reptiles like Chameleons have a vision of 360 degrees. Their eyes can move in different directions independently. This help them have two images at the same time.
