Seta (plural: setae) is a biological term derived from the Latin word for "bristle". It refers to a number of different bristle- or hair-like structures on living organisms.
In zoology, most "setae" occur in invertebrates.
In botany, "seta" refers to the stalk supporting the capsule of a moss, hornwort or liverwort, and supplying it with nutrients. The seta has a short foot embedded in the gametophyte from which it grows. Setae are not present in all mosses, but in some species they may reach 15 to 20 centimeters in height.[2]
The development of adhesives that detach at will yet display substantial stickiness is of great importance for various technological fields.[3][4]
