| The Sinaloan Pocket Mouse is small, with a long, brownish, sparsely-haired tail and a few bristles on its rump. Males are about three inches long, not counting their tails, and females are a little shorter. The tail is longer than the head and body. Like other Chaetodipus, the soles of their hind feet are naked. These pocket mice live on coastal plains, on fine or sandy soil, often among cactus or thorny shrubs, which can provide good protection from owls and other predators. Apparently they do not venture into the mountains: the highest elevation where they have been located was 90 meters. They are seed-eaters: they have been caught with their cheek pouches full of grass seeds and cactus seeds.
