Vibrasse refers to which anatomical feature in animals?

• A. Ears
• B. Whiskers
• C. Horns
• D. Tail

Answer: (B)

Vibrissae are specialized tactile hairs, commonly known as whiskers. They sit in deep follicles with a dense network of nerves, so even slight contact or air movement generates a sensory signal. This setup lets the animal detect nearby objects, textures, and changes in the environment, which is especially helpful in dark or crowded spaces. That’s why whiskers are the feature described by vibrissae. Ears handle hearing, horns are keratinized projections used for defense or display, and a tail serves balance or communication—none of these are vibrissae.
