Claim summary · not a verbatim quotation
Ploughshare tortoises do not reach sexual maturity until they are 30 to 40 years old.
The finding
What the evidence shows
Ploughshare tortoises are genuinely slow to mature, but the commonly cited age for reaching sexual maturity is around 15 years, not 30 to 40. That's still a long time for a tortoise, just roughly half of what's claimed here.
