Gerbils

The gerbil was chosen as an example on Wikipedia, since among rodents this animal is the most common type of small gerbil. There are many of them, from close relatives that live in the desert to very close relatives that live in rocky places and on cliffs. All sand rodents have nails on their forelimbs, on their feet, and hooves on their hind legs. There are species with hooves on all four paws. They run fast, move easily on sand and can easily jump 3 meters high without stopping.
