Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (known as laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother.

Apr 28, 2017 · Being oviparous is an evolutionary strategy for reproduction. In this strategy, one or many eggs can be produced. Each egg is a gamete that has the female’s contribution of the genetic material. In many species, the male supplies his gamete in the form of sperm, which must find its way to the egg.

Oviparity, expulsion of undeveloped eggs rather than live young. The eggs may have been fertilized before release, as in birds and some reptiles, or are to be fertilized externally, as in amphibians and many lower forms. In general, the number of eggs produced by oviparous species greatly exceeds.

Oviparous animals reproduce by laying eggs. Animals that lay eggs are known as oviparous. Although fertilization of the egg can take place either internally or externally, hatching into a young one takes place in the external ecosystem, not inside the womb of the mother.

Traditionally this variety was classified into three modes, oviparity (embryos in eggs), viviparity (young born live), and ovoviviparity (intermediate between the first two). However, each of those so-called traditional modes covered a wide range of diverse reproductive strategies.

Oviparity is generally defined as “any spawning of oocytes (unfertilized) or fertilized eggs” and viviparity is defined as “any mechanism for live-bearing or maintenance of development, by either maternal or paternal parent in or on any part of the body”, …

The eggs of birds such as hen and duck carry immature embryo in them. The hard shells of eggs protect them from damage. Once the fetus is matured, the egg hatches. The trait of egg-laying animals is known as oviparity.

Aug 3, 2023 · Oviparity is the property of these animals where the fertilization may be external or internal, but the young ones are always hatched out of the body. Oviparous animals include most fishes, amphibians, reptiles, and even birds. Some invertebrates like insects are also oviparous.

Oviparity refers to the reproductive strategy where animals lay eggs that develop outside the mother's body. This method of reproduction is commonly seen in various species, allowing for greater offspring production and often involving a higher chance of survival for the young in certain environments.

Animals who give birth to live offspring are called viviparous, meaning "live birth." In contrast to viviparous animals, other animals—called oviparous, meaning "egg birth"—give birth to eggs that must develop before hatching.
