I don't think it's well-studied, but I found a paper stating this:
Turtles and tuatara exhibited greater longevity than most other ectothermic tetrapods, with mean longevities of 39 (SE, ±6 years) and 137 years, respectively, compared with crocodilians (21 ± 5 years), squamates (12 ± 2 years), frogs (8 ± 0.6 years), and salamanders (10 ± 1 years) (tables S1 and S2 and data S1), again when corrected for the potential confounding effects of body size and phylogeny [1, p. 4].

That boy has seen some shit in his eleventy-one years, I'll bet.
Wow. Is this a normal age for this spesies?
Their lifespan is 137 according to this.
That is where I found the paper I quoted.

Thanks for the explanation
Time for one last adventure (and settle in Rivendell)!
Incredible, I love animals that can live for so long... this little guy has been around to see so many historical events!
Wise and cultured.
I don't believe it, he doesn't look a day past 87!
That's crazy :o
Beautiful reptile!
By the way, where is this photo from?
The photo is an embed to where it's hosted. If you click on it, you can see where it's from.
Holy crap, I didn't know there was another land animal other than giant tortoises that lived this long.
