Did you know that pigeons have better vision than us? Have you ever wondered how animals and birds actually see the world? What do fish see when they look at us? This video will explain all these to the smallest details!

SUMMARY
- Vision of snakes differs the most from ours – they sense thermal signatures. Due to the infrared-sensitive receptors on their snouts, some snakes can ‘see’ the radiated heat of warm-blooded mammals.
- Cows don’t see colors as clearly as human. You’ve probably never heard about this: they see the world in a red-orange color scheme.
- There is a blind spot where horses can’t see at all – directly in front of their faces. This is because of their eye location. Also, horses don't see as many colors as we do.
- Fish eyes have ultraviolet receptors and a more spherical lens than we have. They see the world in green, red, and blue colors, but can’t see red and blue. Deep sea fish can easily see in the dark.
- As for birds, they have something similar in their vision – unlike humans, birds can see ultraviolet light. Thanks to the structure of their eyes, they can focus on certain places.
- Flies have thousands of individual visual receptors that collectively create a broad field of vision. Also, they see the world in slow-motion and can see ultraviolet light.
Another insect, a bee, has an unusual vision as well. It's a surprising fact but bees can't distinguish red color at all! For them the color red appears to be dark blue.
- Rat vision is quite blurry, and they can’t see red. They also see the world in slow-motion. Each eye moves independently so they can have two images of the world.
- Cats don't distinguish red and green shades, and their world is made up of brown, yellow, and blue shades. The cat's field of view is broader than ours so they can see more on the sides.
-Dogs can’t see red and orange colors, but they clearly see blue and violet, as well as ultraviolet light. Moreover, they are able to differentiate between 40 shades of gray!
- Frogs can notice only moving objects. They can literally starve to death in the abundance of food if the food does not move! Frogs can also focus only on certain things, so they don’t concentrate on what they don’t need (for example, shadows).
- The eyes of chameleons can rotate in different directions independently, so they have a 360-degree field of vision. They see two images at the same time: one in the front and the other one behind.
