AnAge entry for Thomomys talpoides
Classification (HAGRID: 02978)
- Taxonomy
-
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia (Taxon entry)
Order: Rodentia
Family: Geomyidae
Genus: Thomomys
- Species

Lifespan, ageing, and relevant traits
- Maximum longevity
- Not yet established
- Observations
In the wild, these animals do not commonly live for more than two years [0538]. They have been reported to live up to 6 years, though [0610]. Little is known about their longevity in captivity and without more detailed studies their maximum longevity must be classified as unknown.
