The average lifespan for chimps in captivity is 50-60 years, so Cheetah reaching age 80 is quite remarkable.
Some other animal species with very long lifespans include: macaw 80-100 years; eels 150; Japanese koi 200+; Galapagos tortoise 190; bowhead whale 200.
Here's a factoid to dazzle your friends: One species of jellyfish, Turritopsis nutricula, reverts to a sexually immature stage after reproducing, rather than dying as in other jellyfish. As a result, the species is considered biologically immortal and has no maximum lifespan.
