We all are aware of the fact that animals don't have vision like we human beings do. Some have it better but some can only see the world as black and white. But have you ever wondered how they really see the world? Well, now here's an answer to that question.
Here are different aspects of vision for 13 animals.
Our best friends just have two elements of cones in comparison to humans. Cones are cells responsible for color vision. In other words, dogs are basically colorblind.
They are one of the two species on this planet that can transmit and see in the polarized vision. It serves a protective function for these species so that they can hide themselves from predators.
Being nearly colorblind during the day due to lack of cones once again, our feline partners can see so much better in the dark due to the presence of rods. Rods are responsible for night vision. They require about 1/6th of the light that we humans need to see things clearly in the dark. Suddenly I want a cat protecting me at night.
Their eyes are 350 times more sensitive to light as compared to human eyes, which renders them to capture every little detail very clearly. They have supersized cones, so color vision isn't compromised as well.
Our very own grazing cows don't see the grass being greener on the other side. Rather, they can only see orange and red. But this limitation is substituted by a greater range of vision as compared to humans.
They have a great sense of picking up the blue, green and red parts of the UV spectrum. Although, their clarity isn't very good, but the UV colors are useful for locating the pollens from flowers.
These beautiful bees can detect color 3 times faster than human eyes. It helps them navigate through flowers easily.
Along with having excellent vision, chameleons are the only vertebrates who have monocular focusing. It means they can perceive depth with JUST ONE EYE! On top of that, a chameleon can look through 360 degrees whereas humans are only capable of looking through 180 degrees of their eye range.
A giraffe's vision is also spectacular when it comes to sharpness and range of vision. They utilize their height and vision in order to keep an eye on predators and also, warn other animals of any impending danger.
Giant as it comes, its got the largest eyeballs in the world. Their eyeballs are the size of a basketball. Along with that, they can spot objects or animals from over 400 feet away.
Usual animals have only three photo-receptors to perceive color and distinguish between colors. The Mantis Shrimp has 12 photo-receptors including one to detect polarized light. It is known to have great protective functions and it is also used as a form of communication.
Bats are called as flying foxes with a superior quality of rods and cones for color and night vision. Smaller bats can also rely on SONAR to locate their preys.
Their excellent predatory skills come from their infrared vision. They can easily detect the thermal images of their prey even during the dark.
