In anatomy, an eyestalk (sometimes spelled as eye stalk or known as an ommatophore) is a protrusion that extends the eye away from the body, giving the eye a better field of vision t is a common feature in nature and frequently appears in fiction.
In nature, eyestalks are sometimes called tentacles, and may also have olfactory organs at the end. Examples include snails, the trilobite superfamily Asaphida, and fly family Diopsidae. The crustacean family Polychelidae have eyestalks but no eye.
Many Dalek variants have a horizontal eyestalk.
