The Persian jird is a small rodent with a long tail that lives in dry areas of Western Asia. It digs deep burrows and is well adapted to life in a hot climate with little water.
The Persian jird differs from other gerbils in its larger body and long tail with a tuft. It is important for nature as a seed disperser for plants and as food for snakes, foxes, and birds of prey.
