The Tucuman tuco-tuco is a small rodent that lives underground in northwestern Argentina. It digs long complex burrows, feeds on plant roots, and makes characteristic loud sounds.
The Tucuman tuco-tuco differs from other species by its limited habitat in Tucuman province. It loosens the soil when digging burrows, which helps plants grow, and serves as food for snakes, birds, and foxes.
