Dogs
Dogs can’t see the difference between the colours red and green.
Cats
A cat’s eyes color can vary vastly! By the way do you know the nose pad of a cat has a unique pattern just like a human’s fingerprint?
Horses
The eyes of this animal are one of its most sensitive areas including ears and nose. Via touch, this creature perceives and responds immediately to changes in its environment, sensing contact as subtle as an insect landing anywhere on the body.

Goats
Goats’ eyes are creepy because they have a horizontal pupil. So do horses and cattle.
Owls
An Owl’s eyes are large in order to improve their efficiency, especially under low light conditions. In fact, the eyes are so well developed, that they are not eye balls as such, but elongated tubes. They are held in place by bony structures in the skull called Sclerotic rings. For this reason, an Owl cannot “roll” or move its eyes – that is, it can only look straight ahead!
Frogs
Frog eyes come in a stunning range of colors and patterns. Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement. The bulging eyes of most frogs allow them to see in front, to the sides, and partially behind them. When a frog swallows food, it pulls its eyes down into the roof of its mouth. The eyes help push the food down its throat.
Eyes positioned atop the head give frogs a field of vision of almost 180 degrees. This peripheral vision helps them spot predators and prey.
Chameleons
A chameleon’s eyes can look in different directions – at the same time!
Butterflies
The eyes of butterflies are large spherical structures. These are compound eyes consisting of thousands of hexagonal shaped omatidea. Each omatidea, or miniscule sensor, is directed at a slightly different angle from the others. Collectively they are directed in every direction — up, down, forwards, backwards, left and right. Because of this, butterflies are able to see in virtually every direction simultaneously.
