[3] R. afer is native to southwestern Africa, where its range includes southern Angola and northern Namibia.
It is adapted to desert life and is found in a range of habitats both on the Atlantic coast and many kilometres inland.
Geckos in the genus Rhoptropus are diurnal; their ancestors were nocturnal, but they have secondarily returned to daytime activity.
Compared to the other members of its genus, the Namib day gecko is a runner rather than a climber.
However, in dim light, such as experienced on foggy days on this coast, its maximum speed is significantly lower.
