Beetles have compound eyes, which means the two big shiny eyes on the head are actually made out of many smaller parts. Sometimes the two eyes are each divided in half so that it looks like there are four eyes. One beetle family, the whirligig beetles, has divided eyes so that when they are swimming they can see on top of the water and under the water at the same time. A few beetles have extra simple eyes (usually two) called ocelli. The ocelli are on the top of the beetle’s head.
