How Long do Polar Bears Live in the Wild. As far as mortality rates and lifespans are concerned, all marine mammals have longer lifespans. Speaking mammals in general, lifespan is typically related to the size of species, the larger the mammal is the longer. However, in case of marine mammals the rule holds within the same family. Male and female polar bears live up to 29 and 32 years respectively while in captivity they have a lifespan of 40 years or more. In the Arctic female polar bears give birth in between December and January in winter.
