These species reach sexual maturity when it grows up to a size of (2.3 to 2.9) meters in male and (2.5 to 3.5) meters in female respectively. The female tiger sharks are known to mate once every three years. The tiger sharks breed by the process of internal fertilization. During mating, the male inserts its one of the claspers into the female's cloaca. The males use their teeth to hold the female during the mating process. The tiger shark is the only species in their family that is ovoviviparous. It means their eggs hatch internally and the young are born live when fully developed. The baby tiger sharks are (51 to 76) cm in length. The life span of these species is not known accurately but most often they can live longer than 12 years.
