the gestation period between humans and elephants is much different. Interestingly Galapagos tortoise also experience a late puberty stage, yet live for up to 150 years..

Elephants gestation is about twice as long as humans, which given their large size seems unsurprising.

The long life and late puberty of tortoises does seem a little strange, but (to me) not to the extent of Greenland sharks.

How long do Greenland sharks live?

Long time. Earlier in the thread, I think +500 years was mentioned.
