Observations

One virgin animal reportedly lived 12 years in captivity (Kiklevich, J.V., pers. comm.).

A study comparing rodent species has found that when comparing different rodent species, maximum longevity is associated with smaller rates of protein turnover. Animals of this long-lived species may have evolved towards reducing the energetic cost of continuous protein turnover, which in turn would lessen the quantity and the damage caused by reactive oxygen species produced in this process [1334].
