Like all gerbils, the pygmy gerbil is nocturnal, only venturing out of its simple burrow at night to forage for seeds and other food buried in the sand (6) (7). It is these seeds which limit the distribution of the pygmy gerbil, as it can only inhabit regions where the climate it suitable for seed production (8).
As is typical for many Gerbillus species, it is likely that the pygmy gerbil breeds seasonally, with the young being born blind and naked in a desert burrow, lined with the fur of the mother, after a gestation period of about three weeks (7). A week after birth, these naked gerbils begin to grow fur, and two weeks after this the young open their eyes for the first time (7).
Other members of the Gerbillus genus live a nomadic life, moving about from area to area within their range, and making only simple burrows in the cracks of the desert floor (7).It is likely that the pygmy gerbil also behaves in this way, given its presence in many desert areas only during wetter years (6).
