How do sharks breed?

There are three main breeding modes of sharks: ovoid, ovoviviparous and viviparous. Sharks are fertilized in the body.

Oviposition types are mostly used by large sharks. Eggshells are very strange. Sharks lay eggs. Most kinds of eggshells are rectangular with extended tendrils at the four corners, and the eggs will be wrapped around algae, stones and other objects to hatch.

Viviparous is that a fertilized egg develops into a fetus in the mother's womb and finally comes into being. Viviparous type is the close relationship between the fetus and the mother, and finally gives birth.
