Do females or males live longer?

What is the average lifespan of an elephant?
Answer Wiki. According to the National Elephant Center, “Studies show African elephant life expectancy to be 41 years for females and 24 years for males, though the maximum lifespan for females is more than 65 years and close to 60 years for males.”. So it would seem that males have a shorter life span than females.
Are there male and female elephants?
Male Elephants. In the wild, whenever you see an adult elephant all alone, you can safely bet it is an adult male. Just as female elephants never like to be alone, and choose to spend their entire lives in the company of their mothers, sisters and daughters, the very opposite is true of adult males.

How does age affect a female elephant’s reproduction?
Age affects female reproductive success. Elephants mature slowly, and have a long reproductive lifetime. Female elephants give birth to single calves (although twins have been recorded) at approximately four to five-year intervals and have been documented with up to 12 offspring per lifetime, though this number is rare.
