Kangaroo rats, small mostly nocturnal rodents of genus Dipodomys, are native to arid areas of western North America.The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents (e.g., dipodids and hopping mice).

Kangaroo rat and kangaroo mouse – similar heteromyid rodents native to North America; an example of convergence; Kultarr – a marsupial with a similar body plan and coloration; another example of convergence; they use quadrupedal locomotion, but their large aerial phases cause them to be confused with hopping mice
