What term is used for animals that lay eggs where embryonic development occurs outside the mother?

The term that describes animals that lay eggs where embryonic development occurs outside the mother is "oviparous." In oviparous species, the fertilized eggs are laid in an environment that allows the embryos to develop independently. This is a common reproductive strategy in many groups of animals, including birds, reptiles, amphibians, and most fish. The eggs provide nutrients and protection to the developing embryos until they are ready to hatch.

In contrast, viviparous animals give birth to live young after a period of gestation, meaning the development occurs inside the mother’s body. Ovoviviparous species also carry eggs internally, but the embryos develop within the egg and are born live, so they do not rely on a direct placental connection with the mother. The term "omnivore" does not relate to reproduction but instead refers to dietary habits that involve consuming both plant and animal matter. Thus, the term “oviparous” specifically encapsulates the defined mode of reproduction involving external egg-laying and development.
