San Bernardino kangaroo rat
The San Bernardino Kangaroo Rat, ''Dipodomys merriami parvus'', is a species of rodent in the family Heteromyidae. It is one of 19 recognized subspecies of Merriam's Kangaroo Rat (''Dipodomys merriami'') that are spread throughout the arid regions of the southwestern United States and Mexico.
Like ''D. merriami'', the San Bernardino Kangaroo Rat has the diagnostic trait of having four toes on its hind legs. Additionally, because of its geographic isolation, it has become the most highly differentiated subspecies of ''D. merriami''.
==Description==
The San Bernardino Kangaroo Rat follows the same body plan as ''Dipodomys merriami'' and other kangaroo rat species: large hind feet for jumping, long tail for balance while jumping, cheek pouches for foraging, and so on. Its body is about 95 millimeters (mm) (3.7 inches (in))long, with a total length of 230-235mm (9-9.3 in). Its body color is weakly yellow with a heavy overwash of dusky brown. The tail stripes are medium to dark brown, with dark brown tail hairs and foot pads. Its flanks and cheeks are dusky.
''D. m. parvus'' is substantially darker and smaller than the other two ''D. merriami'' subspecies that live in Southern California (''Dipodomys merriami merriami'' and ''Dipodomys merriami collinus''). This marked adaptation to its habitat has led Lidicker to say that "it seems likely to have achieved nearly species rank." (Lidicker 1960)
