Phacopid Eyes
The most striking feature of the morphology of Phacops rana and its relatives is their eyes. These differed from the eyes of most trilobites in having comparatively few lenses spaced between deep sclera. The lenses themselves were very rounded instead of largely flat. The eyes were mounted on turret-like structures which could swivel, providing the animal with an almost 360 degree field of view. This type of eye is known as the schizochroal eye.

Famous quotes containing the word eyes:
“Could a greater miracle take place than for us to look through each other’s eyes for an instant? We should live in all the ages of the world in an hour; ay, in all the worlds of the ages. History, Poetry, Mythology!—I know of no reading of another’s experience so startling and informing as this would be.”
—Henry David Thoreau (1817–1862)
