What is oviparous?
Oviparous is reproduction by laying eggs, which very few species of sharks do. The ones that reproduce this way tend to be bottom-dwelling species, such as catsharks, horn sharks, and zebra sharks. Shark eggs function in the same way as does a chicken’s egg. The eggs serve as an external womb in which the baby shark grows until it is fully developed. The shark’s tough, leathery outer shell protects the developing embryo inside while he feeds a yolk sac that provides all his nourishment prior to birth.
