Lifespan, longevity, and ageing
Maximum longevity: 30.3 years (captivity) Observations: Despite its short longevity, this animal does not show explicit signs of ageing (Brocas and Verzar 1961). Reproductive senescence has not been demonstrated, but growth rates appear to slow down with age. An increased tensile strength in tendon collagen with age, a frequent marker of ageing in mammals, as been reported (Kara 1994).
