Did you guys know that a Chameleon also has one?
I bet you didn't! It is only sensitive to violet and blue light. It ignores other wavelengths of colour!
Good to know eh!
Bet u didn't know this either....
Fossils of certain extinct fish, amphibia and reptiles also show the third eye. The pineal gland in the brains of humans and other mammals probably evolved from the third eye. In mammals the pineal gland no longer senses light directly; it gets information about brightness from the other two eyes, and then produces hormones that affect sleepiness and wakefulness, including jet lag.

Which also explains why a chameleon is able to change colours. If you wanted to know
