This is a Gerbil.
Like hamsters, gerbils do the same thing with their teeth: they gnaw on things to make their teeth smaller. Gerbils can camouflage with sand because of the color of their fur, meaning that gerbils have the same color fur as the sand to hide from their predators. Gerbils use their tail for balance when they jump. They also use there strong claws to dig. The for on the gerbils feet help him to walk on ho sand and not sink in.
