How many eyelids does a rabbit have?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

Rabbits have a total of three eyelids for each eye. The primary two are the upper and lower eyelids that most animals possess. The unique addition for rabbits is a third eyelid, known as the nictitating membrane. This membrane is located in the inner corner of the eye and serves an important purpose: it helps protect the eye and keep it moist without obstructing vision. This specialized adaptation is particularly beneficial for rabbits, which are prey animals and rely on keen vision to detect threats in their environment. Understanding the anatomy and function of a rabbit's eyelids provides valuable insight into their overall health and biology.
