| As you might guess from its common name, the Narrow-skulled Pocket Mouse has a smaller, narrower head than other Chaetodipus. The bristles on its rump are less well-developed and it has less hair on its tail, especially toward the tip, where the scales show. Males are quite a bit bigger than females. They are found in a variety of habitats, from rocky canyons to mesquite desert to the edges of fields. Populations that live where the soil is dark have darker coats than those that live in sandy habitat. Like other pocket mice, they are primarily seed-eaters and stuff the seeds they gather into their cheek pouches.
