What structure replaces the true eyelid in *Lepidophyma flavimaculatum* for eye protection?
Answer
A transparent scale known as a brille.
A significant adaptation shared by members of the Xantusiidae family, including this species, is the complete absence of a traditional, movable eyelid that allows blinking. To safeguard the eye from injury and desiccation in their humid environments, the eye is instead covered by a fixed, transparent scale. This specialized scale is referred to as a brille, functioning similarly to the spectacle found covering the eyes of snakes or certain geckos, providing constant visual protection.
