GlossaryVibrissae

specialized hairs, like whiskers, that detect environmental changes

Vibrissae, commonly known as whiskers, are specialized, thickened hairs found on the faces of many mammals, including cats, dogs, and rodents. These tactile hairs are highly sensitive to touch and vibrations, allowing animals to detect changes in their environment, navigate in the dark, and sense nearby objects or prey.
