Dogs

Jumping Spiders

They have eight pairs of eyes. They can see more colors than humans. They can see ultraviolet light（紫外线）. So they see things clearer than we do.

Rats

They can move one eye in different directions while keeping the other eye stop moving. It is to see their enemies better. They can’t see many colors. It’s not necessary because they mostly come out at night. They are good at seeing bright light.

Horses
