The Third Eye

The Parietal Eye

The “third eye” of bearded dragons is formally known as the parietal eye, pineal eye, or pineal gland. This unique feature is a small, photosensitive organ located on the top of their heads. It is positioned between the two regular eyes, making it easy to miss at first glance.

Location and Appearance

The parietal eye appears as a pale, translucent spot on the head of bearded dragons. It is often described as a “scale” or “dot” that differs slightly in color and texture from the surrounding scales.

Functions and Purpose

The parietal eye serves various essential functions for bearded dragons. It is primarily involved in detecting changes in light and shadow, which helps them identify potential predators and remain vigilant in their environment.
