Reproduction: A Great White Shark has never been observed giving birth, however pregnant females have been caught. The Great White Shark is known to be ovoviviparous (young develop in eggs within the mother's body). Females give birth to eight or nine pups that are about five feet in length upon birth. Great Whites reach reproductive maturity when the male is about 12 feet long and the female about 13 feet long. It is thought that Great White Sharks live up to 40 years in the wild, but this estimate may be too low.
