We know that some turtles, sharks and whales can live way more than a century if not multiple centuries, but we don't know that because we have been following them from centuries.
There's a tortoise living on the Seychelle's governor garden since 1882 and has outlived every single governor yet.
We have a picture of it dating 1886: https://upload.wikimedia.org/wikipedia/commons/f/f0/Jonathan...
Is this just a fancy way to say that the tortoise is alive, and whoever was governor in 1882 is dead?
Which makes the “yet” weird, but I suppose it admits the possibility that the office might be restored before the tortoise dies, and the tortoise might not outlive the potential future governor.
That just feels like a long time to be a spider.
