Kangaroo rat (Dipodomys).—Anthony Mercieca/Root Resources
Any of about 25 species (genus Dipodomys, family Heteromyidae) of rodents that leap about on their hind legs; found in dry regions of North America. They have large heads, large eyes, short forelimbs, long hind limbs, and fur-lined external cheek pouches that open alongside the mouth. They are 4–6.5 in. (10–16 cm) long without the long tail, which usually ends in a furry tuft. They are pale buff to brown above and white below, with a white stripe on each hip. They forage by night for seeds, leaves, and other vegetation, carrying food in their cheek pouches to store in their burrows, but seldom drink water.
