Every species reproduce in a different way.
Shark mating is not simple to observe, although most species do it while they swim parallel to each other and the male inserts a clasper into female’s oviduct.
There are three ways in which shark pups are born:
Sharks lay eggs in a hidden place in the ocean.
Sharks have placental links with the developing eggs and pups born alive and fully functional.
Eggs develop inside the oviduct and hatch inside the oviduct where they finish their development. Pups born alive and fully functional, but there are not placental links from the mother to the eggs.
Ovoviviparity is the method used by most shark species.
