The Salta tuco-tuco lives in Argentina's dry scrub and feeds on roots, branches, and leaves. It digs burrows at the bases of plants.
The Argentina SIB page lists separate measures for head and body, tail, hind foot, ear, and weight, but the displayed values have no units. It gives no coat-color description, so no visual trait is inferred from those numbers.
It is active at dusk and night, eats roots, branches, and leaves including those of Larrea, and digs burrows at plant bases. The profile also describes it as vocal.
An extinction-risk assessment has not been added yet.
