Banded Gecko
Coleonyx variegatus · also called western banded gecko
A banded gecko blinks its eyes normally as it pauses on open desert ground at night, a simple action most other gecko species are physically unable to perform. Nearby, a wall-climbing relative instead licks its own permanently exposed eye clean, a reminder of just how differently geckos can be built.
Overview
The banded gecko, Coleonyx variegatus, is a small, nocturnal lizard native to arid desert habitat across the southwestern United States and northwestern Mexico. Its functional movable eyelids and soft, delicate skin set it apart from the majority of gecko species worldwide.
An eye built the old-fashioned way
While most geckos evolved a fixed, lick-cleaned eye covering, the banded gecko retained the more typical reptilian blinking eyelid, a reminder that even within a single closely related family, fundamental anatomy can still vary in surprising ways.
Status
Least Concern — widespread and stable across suitable desert habitat throughout the southwestern United States and northwestern Mexico.
Banded Gecko: common questions
Why can the banded gecko blink when other geckos can't?
A banded gecko has functional, movable eyelids, an unusual trait among geckos since most gecko species instead have a fixed, transparent scale covering the eye that they clean by licking with their tongue rather than blinking, making the banded gecko's eye anatomy genuinely distinctive within its own family.
Can a banded gecko climb walls like other geckos?
No, a banded gecko lacks the specialised adhesive toe pads found in many other gecko species, meaning it cannot climb smooth vertical surfaces the way wall-climbing geckos can, and instead relies on moving across open desert ground and sheltering within rock crevices and burrows.
Does a banded gecko's pattern change as it grows?
Yes, a young banded gecko typically displays bold, dark crossbands against a lighter background, but this pattern tends to break up into more scattered spots and blotches as the gecko matures into an adult, making juveniles and adults noticeably different in overall appearance.
Where does the banded gecko live?
The banded gecko is native to arid desert and semi-arid habitat across the southwestern United States and northwestern Mexico, generally sheltering in rock crevices or burrows during the day and emerging at night to forage once temperatures cool.
