Detailed explanation-1: -The nictitating membrane is a transparent or translucent third eyelid present in some animals that can be drawn across the eye for protection and to moisten it while maintaining visibility. Fully developed nictitating membranes are found in fish, amphibians, reptiles, birds, and mammals but are rare in primates.

Detailed explanation-2: -Nictitating membranes are common in the animal kingdom: They’re found in reptiles, amphibians, birds, fish, and even some mammals. (In fact, humans have a homologous wedge of tissue in the inside corner of each eye-a vestigial trait that serves as a reminder of our evolutionary past.)

Detailed explanation-3: -The nictitating membrane of the red-eyed tree frog (Agalychnis callidryas) has a spectacular tiger-stripe design, which camouflages the bright red color of the eyeball without compromising the frog’s vision. Just like our eyelids, they serve to protect the eye underwater and keep it moist on land. 2.

Detailed explanation-4: -5. Locate the frog’s eyes, the nictitating membrane is a clear membrane that attached to the bottom of the eye. Use tweezers to carefully remove the nictitating membrane. You may also remove the eyeball.

Detailed explanation-5: -nictitating membrane. noun. : a thin membrane found in many vertebrate animals at the inner angle or beneath the lower lid of the eye and capable of extending across the eyeball. called also membrana nictitans, third eyelid.
