The tuco-tucos are members of a group of rodents that belong to the family Ctenomyidae. The tuco-tucos belong to a single genus

Degu
The degu is a small caviomorph rodent that is endemic to central Chile.It is sometimes referred to as the brush-tailed rat, and is also called the common degu, to distinguish it from the other members of the genus Octodon. Other members are also called degus, but they are distinguished by...

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 centimetre in length, and they can weigh up to 700 g (24.7 oz).

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