Final answer:
Sharks are not oviparous. Most species of sharks are ovoviviparous, meaning that the fertilized egg is retained in the mother's body and the offspring are born alive.
Step-by-step explanation:
Oviparity is the reproductive strategy where eggs are laid and embryos develop outside the mother's body. Sharks are not oviparous because they do not lay eggs. Instead, most species of sharks are ovoviviparous, meaning that the fertilized egg is retained in the oviduct of the mother's body and the embryo is nourished by the egg yolk. The eggs hatch in the uterus and the young are born alive and fully functional.
