Which of the following terms is also known as vibrissae?

Vibrissae are specialized sensory hairs commonly referred to as whiskers. These whiskers are thick, long hairs that are sensitive to touch and play a vital role in the sensory perception of certain animals, particularly mammals like cats, rats, and dogs. They help these animals detect their surroundings and navigate effectively, especially in low-light conditions.

In contrast, the other options do not serve this particular sensory function. Skin serves as a protective barrier, a tail can be used for balance or communication but does not have the tactile sensitivity of whiskers, and nails are hard structures that protect the tips of the fingers and toes but also lack the tactile sensory ability that vibrissae possess. Thus, the correct relationship between vibrissae and whiskers confirms their role as important sensory tools in the animal kingdom.
