How Animals See Things
Many people think animals see things like humans do. But this is not true! Most animals have their own unique way of seeing things.
Dogs cannot see some colors. They can only see gray, blue, and yellow. Some scientists believe that red and green appear yellow to dogs. So dogs think red and green tomatoes are all yellow! But dogs have better night vision than humans. That is why your pet dog easily moves around in the dark.
Horses’ eyes give them an extremely wide view. That is because their eyes are on the sides of their heads. It allows them to see about 350 degrees around them. So horses can easily sense approaching predators and run away. However, horses cannot see things that are right in front of them! They have a blind spot in the space between their two eyes.
Dragonflies’ eyes have about 30,000 lenses. Their eyes can see about 360 degrees around. Also, dragonflies are very good at sensing motion. They can see most movements in slow motion. Dragonflies catch their prey while flying. Their strong vision makes this easier to do.
