Researchers examining southern right whales found that the median life span for the species was 73.4 years, and that 10 percent of individuals survived past 131.8 years. ... tends to live longer ...
The maximum lifespan of the freshwater pearl mussel (Margaritifera margaritifera) may be 210–250 years. [78] [79] [80] Some confirmed sources estimate bowhead whales to have lived at least 211 years of age, making them the oldest mammals. [81] Rougheye rockfish can reach an age of 205 years. [82]

In captivity, they often develop pathologies, such as the dorsal fin collapse seen in 60–90% of male killer whales. Captives have vastly reduced life expectancies, on average only living into their twenties. In the wild, females who survive infancy live 46 years on average, and up to 70–80 years in rare cases.

Mammals range in size from the 30–40 millimetres (1.2–1.6 in) bumblebee bat to the 30 metres (98 ft) blue whale—possibly the largest animal to have ever lived. Maximum lifespan varies from two years for the shrew to 211 years for the bowhead whale.
