What are oviparous viviparous and Ovoviviparous?

Answer: Oviparous animals lay eggs (e.g. birds), while viviparous animals give birth to their young ones (e.g. humans, cats, dogs). Ovoviviparous animals produce eggs, but instead of laying, the eggs develop within the mother’s body. Example- Shark.

Are frogs ovoviviparous?

Among frogs and toads, the majority are oviparous, some are ovoviviparous (lecithotrophic mode of viviparity: growing embryos and larvae feed exclusively upon the yolk contained in the egg, which is retained within the oviduct or in some ‘ectopic site’ such as the vocal sac or a specialized venue inside the stomach).

In the case of viviparous animals, since they do not hatch eggs, embryonic development takes place inside the mother’s body, i.e., the female reproductive system. Once the fetus is fully developed, the baby is delivered from the mother’s body.
