How do sharks give birth?
Ovoviviparity: Most sharks are ovoviviparous; they combine the first two methods. They produce eggs, but instead of hatching outside the body as in oviparity, the eggs are carried within the female for the gestation period. When the egg hatches, the shark pup continues developing inside the female until it's born.
27 related questions foundCan sharks have babies without a mate?
In sharks, asexual reproduction usually happens via a process called "automictic parthenogenesis," explained Feldheim. During egg development, one egg is produced along with three other products called polar bodies. Usually these polar bodies are simply reabsorbed by the female.
Do mother sharks eat their babies?
Shark embryos cannibalize their littermates in the womb, with the largest embryo eating all but one of its siblings. Now, researchers know why: It's part of a struggle for paternity in utero, where babies of different fathers compete to be born.
How do great white sharks get pregnant?
Mating has yet to be fully documented in white sharks, but it is assumed to be similar to internal fertilization in most sharks—that is, the male inserts his claspers into the cloaca of the female.
