vibrissae

n. stiff sensory hairs or whiskers on the face of a mammal (e.g. hairs in the nostrils of a human); bristly feathers near the beak of an insect-eating bird

Vibrissae (singular: vibrissa), or whiskers, are specialized hairs, usually employed for tactile sensation, but can also refer to the stiff feathers near the mouths of some birds. Vibrissae hairs commonly grow around the nostrils and other parts of the face in most mammals, commonly on cats as 'whiskers', as well as on the forelegs and feet. Vibrissae are usually thicker and stiffer than other types of hair.
