Haig's tuco-tuco, known regionally as the Patagonian tuco-tuco, is a hystricognath rodent. Like other tuco-tucos it is subterranean and thus not often observed, although the "tuc-tuc" call of the males can be heard near burrow sites, especially in the early morning. Like most species in the genus Ctenomys, C. haigi are solitary, with one adult per burrow.
