Scientists believe the white shark gestation period lasts about 12 months, which means that female white sharks may breed only once every two years. This slow rate of reproduction indicates that it would take a long time for white shark populations to recover if they became severely depleted.
The Birthing Process The great white shark is ovoviviparous. In other words, a shark grows inside an egg and hatches inside the mother. Afterward, the shark pup is born. While they are still in the womb, the shark pup will feed on the unfertilized eggs in order to keep growing.
The great white shark is ovoviviparous, which means that the shark grows in an egg, which is then hatched inside the mother. Shortly thereafter, the shark pup is born. Because of the long gestation period, it's possible that female great whites give birth every other year, taking some time to rest after mating.
OVIPARITY (egg-laying) Skate, chimaera and some shark species produce eggs encased in a tough 'leathery' eggcase. A female may spend a long time laying her eggs, ensuring they're securely fixed in a safe place. It can take between 6-9 months before they're ready to hatch.
Some shark species lay eggs that hatch once they are ready, similar to how many might imagine a bird egg hatching. Unlike with birds however, mother sharks do not stick around until the eggs hatch. Once the baby shark inside the egg is developed, it hatches ready to defend itself with no mother to protect it.
Shark embryos cannibalize their littermates in the womb, with the largest embryo eating all but one of its siblings. That finding suggests the cannibalism seen in these embryos is a competitive strategy by which males try to ensure their paternity.
Some sharks lay eggs, while others give live birth. Great white sharks gestate their pups for a year before giving birth – that's longer than humans. Between 2 to 12 babies are born at a time.
Pregnant females come into the same place as they were born, to deliver their young. The baby sharks then hide from predators under rocky and coral overhangs during the daytime. They'll stay here up until the age of four years old, only moving house when they outgrow it.
Pregnancy lasts years for some species. Some scientists estimate that basking shark gestation lasts up to 3.5 years. Frilled sharks may also carry their pups for more than three years. Some smaller species are at the other end of the spectrum. Bonnethead sharks, for example, give birth after around five months.
Once viviparous pups are developed enough inside the womb, the mother gives birth and leaves them on their own. Even though shark moms' responsibilities to their pups end when they give birth, Dr.

When the last Iowa-class ship was finally stricken from the Naval Vessel Registry, no battleships remained in service or in reserve with any navy worldwide. The U.S. has eight battleships on display: Massachusetts, North Carolina, Alabama, Iowa, New Jersey, Missouri, Wisconsin, and Texas.
