Some scientists believe that the life expectancy of the Great White Sharks is around 30 years (Levine, 1988) but other research indicates that they can reach up to 40 years. The lifespan of Tiger Sharks in the wild is believed to be 27 years in average, although some may live up to 50 years of age. Like with other species, tiger sharks in captivity do not live as lengthy as in wildlife reaching only 17 to 20 years.
