It is believed that most sharks live on average up to thirty years of age, which is pretty old for just a fish. There has been recordings of GWS reaching the age of 50 years! That’s older than my parents! Crikey! A main reason for the the jump difference in lifespan is because the sharks take so long to reproduce, and with humans hunting them for their fins, it leaves less adult sharks ( used for largeness of fins) to reproduce, therefore it has to be the younger ones. Since gestation can be almost two years later, that makes less litters being put out there, and the pups that do survive barely stand a chance once they’re big. Great White Sharks simply do not survive in captivity as they constantly need to move to breathe and have access to high fat food (seals, sea lions, other sharks).
