This is an inhabitant of rocky habitats, where it shelters in fissures and rock crevices, and under rock formations. The species does not burrow and appears to be less well adapted to desert conditions and than either C. vali or Felovia vae. It is a diurnal species that lives in small family groups of between three and 11 adults, wit one to three male. The group occupies a common territory, which is marked and defended. The species has a gestation period of 73 days with a litter size of one to four young. There are usually two litters per year.

Ctenodactylus gundi ranges from eastern Morocco, through Algeria and Tunisia, to western Libya. It occurs mainly on the southern slope of the Atlas Mountains, where it has been recorded at altitudes from 230 to 2,900 m. The limit between the distribution of this species and C. vali in the west of the Saharan Atlas varies according to precipitation, with C. gundi disappearing in dry periods, and C. vali then occupying these areas.

It has been recorded from the Eastern Atlas National Park in Morocco, and is presumably present in other protected areas.
