Ecological Role
Critical seed dispersal agent, contributes to ecosystem seed distribution and soil aeration through burrowing activities; serves as prey for multiple predator species in desert food webs.
Morphology
SKIN COATPale sandy to light brown fur providing excellent camouflage; short, dense pelage minimizing water loss in arid environments
LIMBS WINGSLong, delicate hindlimbs enabling rapid locomotion; specialized feet with fur-covered soles for desert surface navigation
HEAD SENSORYLarge ears for thermal regulation, prominent whiskers for tactile sensing, small eyes adapted to low-light desert conditions
BODY STRUCTURESmall, slender body measuring 11-15 cm total length, with body mass between 10-20 grams; adapted for rapid movement and heat dissipation
