How long do whale sharks live?
Scientists don t know for certain how long whale sharks live. We do know that some species of sharks that live for 100 years are not able to breed until they are 20 years old. This means they must spend 1/5th (20%) of their lives evading capture until they can reproduce at all. It appears that male whale sharks are not able to breed until they are about 30 years old. If 30 years is 1/5th of a whale shark s expected lifespan, it may then live for well over a century, possibly even 150 years or longer.
