Geochelone radiata

"Maximum longevity: 32.8 years (captivity) Observations: Although the longevity record for this species is 32.8 years (http://www.pondturtle.com/), there is considerable anecdotal evidence that these animals are extremely long-lived, likely living more than a century. There are also anecdotal reports of one animal, called "Tui Malila", offered to the Tonga royal family by Captain Cook that might have lived 188 years. While these claims are unverified, it is likely that the maximum longevity of these animals is significantly underestimated."
