The leopard gecko is a nocturnal ground-dwelling lizard naturally found in the deserts of southern Central Asia, and throughout Pakistan, to the northwestern parts of India. Unlike most geckos, leopard geckos possess movable eyelids.
The native habitat of the leopard gecko is the rocky, dry grassland and desert regions of south-Asian Afghanistan, Pakistan, north-west India, and parts of Iran. Winter temperatures in these areas can be quite low, below 10 °C (50 °F), forcing the animals underground into semi-hibernation, called brumation, living on fat reserves. As nocturnal creatures, they spend the day hidden under rocks or in burrows to escape the daytime heat and emerge at dusk to feed by hunting insects. These Geckos are solitary, and do not usually live with other animals.
