Did you know that only about 95 percent of animals have eyes? Some are very simple, picking up only light and dark conditions while others are more complex. Here are some more interesting eye facts about our animal friends.

  • A chameleon’s eyes can look in different directions at the same time.
  • Many hamsters blink only one eye at a time.
  • Dogs cannot see the difference between red and green.
  • Cats can distinguish yellow, blue and green hues but their eyes are best at detecting movement and shades of gray.
  • Butterflies can distinguish colors in the center of a flower that humans cannot see. This ability aids in pollination.
  • Fish have no eyelids.
  • Ants and flies have compound eyes, meaning each eye is made up of many smaller eyes. These compound eyes are better at detecting fast movements.
  • An eagle can see a rabbit about one mile away.
  • The giant squid has the largest eye on earth. It is 18 inches wide or about the size of a large watermelon.
