Tuco-Tucos: Ctenomyidae

The Magellanic tuco-tuco is listed as Vulnerable, facing a high risk of extinction, by the IUCN due to declining habitat. In southern Patagonia, an area of Argentina between the Andes Mountains and the south Atlantic Ocean, extensive grazing by sheep on grasses and plants eaten by the highland tuco-tuco and other agricultural activities, have caused the animal to become rare and endangered. Three species are listed as Near Threatened, at risk of becoming threatened, by the IUCN: mottled tuco-tuco, Natterer's tuco-tuco, and social tuco-tuco. No other species are listed as threatened by the IUCN.
