About Common American Muskrat (Ondatra zibethicus)

Kingdom: Animals
Phylum: Chordates
Class: Mammals
Order: Rodents
Family: True Mice and Rats, Gerbils, and Allies

Observations: There are conflicting reports about the longevity of the muskrat. In the wild, these animals live about 3 years. It has been suggested that they live up to 10 years in captivity (Ronald Nowak 1999). While this is plausible, it has not been confirmed. One specimen lived 5.8 years in captivity (Richard Weigl 2005). More studies are necessary to better estimate the longevity of the muskrat.
