Blurb from the photographer:

The Helmeted Gecko (Tarentola chazaliae) is a member of the gecko family native to the west coast of Africa.

The size of the adult helmeted gecko is about 4 inches (10 cm). The environment they live in is sandy and rocky desert with sparse vegetation. The gecko is mainly nocturnal. Helmeted geckos require a humid environment.

Helmeted gecko colors can be anywhere from light grey to dark brown. The underside of the gecko is light-colored.

Helmeted geckos are the first vertebrates to be found to see color in very low levels of light.
