Tuco-Tucos: Ctenomyidae


Tuco-tucos range from the tropics to the sub-Antarctic regions at the tip of South America. They seem to prefer coastal areas, grassland, rainforest, deciduous forest, the large treeless semi-arid grassy plains called steppes, and meadows. They are found from sea level up to 13,120 feet (4,000 meters) in the Andes Mountains.

Most species live in a very small geographic area, including the Bolburn's tuco-tuco and the silky tuco-tuco that inhabit extreme southwestern Argentina. There are only several species that have a wider geographic range, such as the collared tuco-tuco, which lives in Argentina, Brazil, and Uruguay, and the highland tuco-tuco, found in Argentina, Bolivia, Chile, and Peru.
