Significance to humans

Tuco-tucos appear in many South American indigenous myths and legends (i.e., Tehuelches and Tobas indigenas). Tehuelches and Onas people eat them. Ctenomys is considered a pest in Argentina. Tuco-tucos may cause problems to humans because they consume crops and roots of timber trees. They can also affect human building activities because of their removal of soil.
