Surprisingly, there is. This is the tuatara, a reptile which looks like a lizard. In some lizards there is a gland at the front of the brain called a pineal body, shaped like an eye. In most of these lizards; the pineal body is not fully developed, and does nothing at all, but in the tuatara's case, it is developed fully, and acts as a third eye.

the lionmouse also, lol thanks for sharing.

thanks for sharing but i never seen one of them in real. Im sure it might be t0o scary to l0ok at

Well, third eye could mean, a spiritually highly developed species.
