Whiskers or vibrissae (/vəˈbrɪsi/; sg.: vibrissa; /vəˈbrɪsə/) are a type of stiff, functional hair used by most mammals to sense their environment.[1] These hairs are finely specialised for this purpose, whereas other types of hair are coarser as tactile sensors. Although whiskers are specifically those found around the face, vibrissae are known to grow in clusters at various places around the body. Most mammals have them, including all non-human primates[2] and especially nocturnal mammals.

Whiskers are sensitive tactile hairs that aid navigation, locomotion, exploration, hunting, social touch and perform other functions.[3]

This article is primarily about the specialised sensing hairs of mammals, but some birds, fish, insects, crustaceans and other arthropods are known to have similar structures also used to sense the environment.
