Eyestalk
olfaction.[1]
In anatomy, an eyestalk (sometimes spelled eye stalk and also known as an ommatophore) is a protrusion that extends an eye away from the body, giving the eye a better field of view.[1] It is a common feature in nature and frequently appears in fiction.[2]
In nature
Eyestalks are a specialized type of
Diopsidae. In slugs and snails, these tentacles will regrow if severely damaged, and in some species, are retractable.[1] Crustaceans also have eyestalks, consisting of two segments. [4]
