Physical Characteristics, Habitat, Behavior And Reproduction, Conservation Status, Pearson's Tuco-tuco (ctenomys Pearsoni): Species AccountGEOGRAPHIC RANGE, DIET, TUCO-TUCOS AND PEOPLE


Central and southern South America, including Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay.

All species of tuco-tucos are believed to be herbivores, meaning they are plant-eaters. Their primary food sources are roots, grasses, herbs, and shrubs.

Tuco-tucos are hunted for their meat by several native South American groups, including the Tehuelches and Onas. Farmers who consider them an agricultural pest because they eat crops often kill them. They can also cause problems for horseback riders when their burrows cave in under the weight of the horses, causing broken legs to the horses and often injury to the riders when they fall.
