The bristle pocket mouse is a small rodent with coarse fur and a long tail. It lives in prairies and steppes of North America and carries seeds in cheek pouches.
The bristle pocket mouse differs from related species with its coarse bristly fur and large cheek pouches. It helps spread plant seeds and serves as important prey for snakes, owls, and foxes.
