How many eyelids does a rabbit have in total?

Rabbits have a total of three eyelids for each eye. This includes two upper and lower eyelids, which are found in many mammals, as well as a third eyelid, known as the nictitating membrane. This nictitating membrane is a thin layer that provides additional protection and moisture to the eye, allowing the rabbit to blink while still keeping the eye partially covered. The presence of this third eyelid is particularly important for protecting the rabbit's eyes in their natural habitat, where debris and environmental factors can pose risks to their vision. This unique anatomical feature allows rabbits to maintain better eye health and protects their vision while they forage or escape from predators.
