Among the various shark species, it is important to note that the majority are viviparous or ovoviviparous, which means they give birth to live young instead of laying eggs. However, there are a few shark species that are indeed oviparous and lay eggs. These include:
1. Carpet sharks (Order Orectolobiformes): Carpet sharks, such as the zebra shark (Stegostoma fasciatum) and the wobbegongs (family Orectolobidae), are oviparous. They lay eggs enclosed in leathery egg cases, commonly known as mermaid's purses or egg capsules.
2. Catsharks (Family Scyliorhinidae): Catsharks are a family of sharks that includes several oviparous species. They lay eggs with a protective case, similar to the carpet sharks.
3. Bullhead sharks (Family Heterodontidae): Bullhead sharks, such as the horn shark (Heterodontus francisci), are also oviparous. They lay eggs with tough, horn-like cases that provide protection.
It's important to note that the majority of shark species are not oviparous but rather give birth to live young. This includes well-known species like great white sharks, tiger sharks, and hammerhead sharks, among others.
