Did You Know?

The eye is an organ that receives light and visual images. Non-image forming eyes (also called direction eyes) are found among worms, mollusks, cnidarians, echinoderms, and other invertebrates. Image-forming eyes are found in certain mollusks, most arthropods, and nearly all vertebrates. Arthropods are unique in possessing a compound eye, which results in their seeing a multiple image that is partially integrated in the brain. Lower vertebrates, such as fish, have eyes on either side of the head, allowing a maximum view of the surroundings, but producing two separate fields of vision. In predatory birds and mammals, binocular vision is more important. The placement of both eyes on the front of the head permits a larger overlap of the two visual fields, resulting in a parallel line of direct sight.
