Detailed explanation-1: -Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes.

Detailed explanation-2: -What are oviparous animals? Animals that reproduce by laying eggs are called oviparous animals. In these animals, the process of both fertilization and embryo development does not occur inside the mother. Birds and frogs are examples of oviparous animals.

Detailed explanation-3: -In fact, all birds are oviparous, as are most fish, reptiles, and insects. The word oviparous is most often used in biology classes to distinguish egg-laying animals from those that give birth to live babies, like humans.

Detailed explanation-4: -Oviparous animals are animals that lay eggs. Fertilization can be external or internal, but the development of the embryo takes place outside the mother’s womb. Fish, amphibians, reptiles, birds, and few exceptional mammals (duck-billed platypus), are oviparous.

Detailed explanation-5: -Birds constitute the only vertebrate class that is both rich in species number and exclusively oviparous.
