Animal with a third eye
You must have seen animals with two eyes, but have you ever seen about animals with three eyes?
The Tuatara or Sphenodon punctatus is a lizard-like reptile with a third eye on top of the head called the pineal eye. The eye is covered by an eyelid which closes horizontally. It can be seen under the skin and has a retina with nerve connection to the pineal gland in the middle of the brain. The pineal gland produces melatonin which influences sleep and hibernation. The amount of light falling on the third ey may thus trigger biological cycles. The third eye is covered by scales after 4 to 6 months.
