There are many ways of seeing. As humans, we're used to seeing at a certain spectrum of light, at certain conditions of light and dark, and for certain distances. We also have some depth perception. In the animal world, things are more varied. Some animals can see in other spectrums than we cannot, including body heat of other animals. Some of them have multiple eyes (insects and spiders for example), and some have almost no sight at all. Some eyes were made to open underwater as well as above (alligators). Due to this difference in sight, animal eyes also come in a variety of shapes and colors. Can you identify these animals purely by their eyes? Then take our animal eye test and see if you've got a zoologist in you just waiting for their mettle to be tested.
