The Jonathan in that Boer War photograph is probably not the Jonathan that lives today -- fraudulently honored as the world's oldest creature.

"Since they have several giant tortoises on St Helena, they simply named the next largest one Jonathan. The date of 175 years old is being assumed because the Jonathan in the photograph of 1901 looks like the Jonathan of today. As they are very difficult to date, no one can say with any certainty that this current, reigning Jonathan is 176 or 150 or even 200."

Very difficult to date....

I guess I’m just like a turtle
That’s hidin’ underneath its hardened shell.
Whoa, whoa, oh yeah, like a turtle
Hidin’ underneath its hardened shell.
But you know I’m very well protected —
I know this goddamn life too well.
