Eyes
In some species, there are very large central eyes. They look like simple eyes or ocelli, but they are in fact surprisingly sophisticated. They can recognise forms, and are used in hunting and avoiding enemies. These eyes are remarkable in their internal anatomy; there is a suggestion that they represent the last step in the integration of the aggregate of simple ocelli into a compound eye, and of further integration of a compound eye into a simple eye. In comparison in species where they are present at all, lateral eyes are only rudimentary.
Famous quotes containing the word eyes:
“...I never drink wine ... I keep my hands soft and supple ... I sleep in a soft bed and never over-tire my body. It is because when my hour strikes I must be a perfect instrument. My eyes must be steady, my brain clear, my nerves calm, my aim true. I must be prepared to do my work, successfully if God wills. But if I perish, I perish.”
—Lisa, Russian terrorist (anonymous)
“His speech is a burning fire;
With his lips he travaileth;
In his heart is a blind desire,
In his eyes foreknowledge of death:
He weaves, and is clothed with derision;
Sows, and he shall not reap;
His life is a watch or a vision
Between a sleep and a sleep.”
—A.C. (Algernon Charles)
““Your eyes that once were never weary of mine
Are bowed in sorrow under pendulous lids,
Because our love is waning.””
—William Butler Yeats (1865–1939)
