Many wild animals live longer in a captive setting.  While there are some exceptions (such as elephants), most animals provided with shelter, a constant supply of food and nutritional supplements, and protection from the wild interactions that might wound, maim, or kill them experience increases in longevity.  And despite the greater life expectancy and longer lifespan, most people understand that wild animals held in a zoo setting do not live the lives they were biologically intended to.
