Tristram's jird is a small rodent with sandy coloration that lives in the arid regions of the Middle East. It digs burrows and is mainly active at night.
The Tristram's jird differs from related species in its unique skull structure and fur coloration. It is important for nature because it disperses plant seeds and serves as food for snakes, birds, and foxes.
