SHARKS Oviparity refers to the several shark species that lay eggs instead of giving birth to live young. These are the minority as most species ore ovoviviparous. Once the females eggs have been fertilised inside her body (as all fertilisation is internal in sharks), she lays them outside, i.e. in the ocean.

During mating, the male shark inserts the clasper (similar to the mammalian penis) into the female’s oviduct and releases sperm. Oviparity is when a shark lays eggs in a deposit in the water. Sharks are “true oviparous” animals meaning the egg is fertilized in the womb then laid. The eggs contain a zygote and yolk sac. They are typical encased a leathery pouch, referred to as a “mermaid’s purse.”.
