The tuco-tucos are members of a group of rodents that belong to the family Ctenomyidae. The tuco-tucos belong to a single genus: Ctenomys, but they include some 60 different species. The relationships among the species are debated by taxonomists. Their closest relatives are degus and other octodontids (Woods and Kilpatrick, 2005). All species of tuco-tuco are found in South America. The tuco-tucos of South America have an ecological role equivalent to that of the pocket gophers of North America.

Tuco-tucos are heavily built with short legs. Their skin is loosely applied, possibly to slide about the tunnels they create. They have long forefeet for burrowing, and bristled hind feet for grooming. They also have large heads, small ears, and hairy tails. Their body ranges in size from 15–25 cm (5.9–9.8 in) in length, and they can weigh up to 700 g (25 oz).^[1]

Among their most notable features is that various members of the genus exhibit differing levels of genetic variability and sociality,^[2] with a tendency for the most social species (e.g., Ctenomys sociabilis) to have the least genetic variation.^[3][4]
