The social tuco-tuco (Ctenomys sociabilis) is a species of rodent in the family Ctenomyidae.Woods, C. A. and C. W. Kilpatrick. (2005). "Infraorder Hystricognathi", pp. 1538–1600 in: Wilson, D. E. and D. M. Reeder. [https://books.google.com/books?id=JgAMbNSt8ikC&pg=PA Mammal Species of the World] (3rd ed.) Johns Hopkins University Press. {{ISBN|9780801882210}}. It is endemic to Argentina. Its natural habitat is subtropical or tropical dry lowland grassland.
Range
The social tuco-tuco is found in the mesic meadows at about 1000 m in elevation. Its range is rather small at about 700 km2, bound by the Rio Limay to the east, the Rio Traful to the north, and the Lago Nahuel Huapi to the south.{{cite journal|title=Ancient DNA evidence of prolonged population persistence with negligible genetic diversity in an endemic tuco-tuco (Ctenomys sociabilis)|year=2003 |volume=84 |page=403 |doi=10.1644/1545-1542(2003)084<0403:ADEOPP>2.0.CO;2|issn=1545-1542 |last1=Hadly |first1=Elizabeth A. |last2=Van Tuinen |first2=Marcel |last3=Chan |first3=Yvonne |last4=Heiman |first4=Kimberly |journal=Journal of Mammalogy |issue=2 |s2cid=86128937 |doi-access=free }}
Behavior
One of the unique characteristics of this species is its social behavior. This is evidenced by observed adult burrow sharing, female tendency to stay near her birthplace, and alloparental care. With this high degree of sociability, however, there seems to be much less genetic diversity.
