I’ve tried looking this up on my own – and the only real answer I seem to get is “how large the animal is”
The internet says *the smaller the animal, the shorter the lifespan*
However, this leaves me with more question….
Why do humans average 70-90 years, but giraffes average 26 years, blue whales average 80-90 years, **and the giant tortoise which is smaller than all of them averages 150 years** ???
