AnAge entry for Blarina brevicauda

Lifespan, ageing, and relevant traits

In the wild, these animals have been estimated to live up to 2.5 years [0542], which could be overestimated. In captivity, they do not appear to live more than 2.2 years [0671], though some anecdotes indicate a longer lifespan.
