The largest eyeball on the planet is 18 inches wide, about the size of a large watermelon and it belongs to The Giant Squid.
An ant has only two eyes. But each eye contains lots of smaller eyes. This is called a ‘compound eye’
Dogs can’t see the difference between the colors red and green.
A chameleon’s eyes can look in different directions- at the same time!
The shark cornea has been used in eye surgery, since its cornea is similar to a human cornea.
An ostrich’s eye is bigger than its brain.
Dolphins sleep with one eye open.
Many hamsters only blink one eye at a time.
The night vision of the Cat is legendary. In order to see, they need only one-sixth as much light as a human. They cannot, however, see in total darkness. When enough light is not available, they use their whiskers to feel their way around.
Your cat’s eyes offer her almost 285 degrees of sight in three dimensions. Idea peripheral vision for hunting.
Cats do see in color, and can distinguish yellow, blue and green hues. Their eyes are best, however, at detecting movement, and shades of gray.
Crocodiles are blind in the water but very keen of sight in the air.
Crocodiles are color-blind.
Owls are the only bird that can see the color blue.
Unlike all other insects, flies have five eyes. They have two large eyes and three smaller eyes between them.
A chameleon’s eyes can look in opposite directions at the same time.
The placement of a donkey’s eyes in its heads enables it to see all four feet at all times.
Dogs can’t see the difference between the colours red and green.
Goat’s eyes are creepy because they have a horizontal pupil. So do horses and cattle.
An owl cannot “roll” or move its eyes- that it’s, it can only look straight ahead.
Leaf Tailed gecko and other nocturnal gecko species can see up to 350 times better than we can in dim light.
“Mantis Shrimp” has the weirdest and most amazing eyes in the world. It has much better color vision than humans (their eyes having 12 types of color receptors, whereas humans have only three). It also has Ultraviolet, infrared and Polarized light vision, thus having the most complex eyesight of any animal known. The eyes are located at the end of stalks, and can be moved independently from each other, rotating up to 70 degrees. Interestingly, the visual information is processed by the eyes themselves, not the brain. Even more bizarre; each of the mantis shrimp’s eyes is divided in three different parts of the same eye. In other words, each eye has ‘trinocular vision” and complete depth perception, meaning that if a mantis shrimp lost an eye, its remaining eye would still be able to judge depth and distance as well as a human with his two eyes.
