The dark kangaroo mouse (Microdipodops megacephalus) is a species of rodent in the family Heteromyidae.

The fat deposits vary in size as the season changes because it is used as a source of energy during dormancy.

[4][6] The dark kangaroo mouse species is native to the west of United States ( southeastern Oregon, northeastern and central-eastern California, Nevada, the tip of southwestern Idaho, and west-central Utah).

[6][1] They inhabit dry desert areas living in loose sand and gravels (found in the Upper Sonoran life zone).

[1][7] Dark kangaroo mice mostly eat small seeds (granivores), which are carried back to their burrows in their cheek pouches.

[4][6][7] Using bipedalism is suggested to be a result of foraging behaviors and using it as a locomotion mode only serves as a side function.
