Comb-toed Jerboa

<em>Paradipus ctenodactylus</em>, the comb-toed jerboa, is a small nocturnal rodent in the family Dipodidae, assessed as Least Concern on the IUCN Red List. It is adapted to arid desert and semi-desert environments and is the sole member of the genus <em>Paradipus</em>. The species is named for the distinctive comb-like fringe of stiff hairs on the toes of the hind feet, which provides traction on loose sand surfaces. Like other jerboas, it is highly specialized for bipedal locomotion, possessing greatly elongated hind limbs relative to its body size, a long tail used for balance, and large ears. <em>P. ctenodactylus</em> is primarily granivorous and insectivorous, foraging for seeds, plant material, and invertebrates in its desert habitat. It digs burrows for shelter and protection from temperature extremes. Geographic range details are not recorded in the current record.
