The fat-tailed Gerbil is Pachyuromys duprasi, a species of gerbil. Its tail becomes fatter when it eats something. Then it uses it when food becomes scarce. They can live 5 to 7 years in captivity. It is from Africa.
They can survive a long time without drinking because they are adapted to a dry climate.
They bury themselves under the sand until night so that there are not as many predators that will attack them.
