The Barkers mention record longevities in their most recent book and reference several ball pythons in their 50s as at least one over 60yrs which leads me to believe it’s this animal.
As for not being reproductive beyond 15yrs, that’s simply not true. I have a friend back home with an animal over 30yrs that still produces regularly, the founder animals to my line of Brisbane carpets produced in their late 20s/early 30s, relatives of my Argentine boa have produced into their 20s...
I think the issue is that few people keep snakes alive past 15yrs and has little to do with the fecundity of the snakes themselves.
