Some whales have a lifespan similar to humans. Blue whales live over 80 years - Fin whales live about 85 years. The Bowhead whale is the longest living mammal. Some bowhead whales have been found with ivory spears lodged in their flesh from failed attempts by whalers 200 years ago. The longest living land mammal (after humans) is the elephant which averages 60 - 70 years old. Humans are the longest living mammal on land.
The longest lived "land" mammal after humans is most probably the elephant (Loxodonta africana) at 65+ years. The longest lived "mammal" is most probably the Bowhead whale (Balaena mysticetus) which has been reported to live 211+ years. For further research on this topic you can look up many species in the AnAge database: http://genomics.senescence.info/species/ Its curator has been gracious enough to document the current known longevity of many species.
