The green iguana has a "third eye," also known as the parietal eye, located on the top of its head. This eye is not used for vision in the traditional sense but can detect changes in light and movement, helping the iguana sense predators from above. It is covered by a layer of skin and scales, making it less functional than its other eyes, but it plays a role in regulating circadian rhythms and thermoregulation.
