There are three ways in which shark pups are born:
- oviparity: eggs incubation takes from 6 to 15 months depending on the species (horn shark, cat shark)
- viviparity: young sharks are born alive (hammerhead shark, bull shark)
- ovoviviparity: embryo develops in egg within the female's body (great white shark)
Sharks do not care for their babies after they are born.
