Each wide, hemispherical eye may had hundreds or even
                     thousands of lenses, each of which perceived an image
                     from a different direction. Some faced straight forwards,
                     others to the side, and some even faced backward. Each
                     lens focused on an area determined for it. The trilobite was
                     thus able to perceive danger approaching from any direc-

                     tion, and also possessed a great advantage when hunting.
