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.

Ovipositor of long-horned grasshopper (the two cerci are also visible). The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs.In insects, an ovipositor consists of a maximum of three pairs of appendages.
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...
Some iguanas species are terrestrial, others prefer living in trees or rocks. The males of most species are territorial and defend their territory against other males, but tolerate females. All iguanas are oviparous. The nests are usually quite large; often several females lay their eggs in close proximity.
The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental. For more information on how these estimates were ascertained, see Wikipedia's articles on gestational age.
Angry residents booed and threw eggs at Spain’s King Felipe and Queen Letizia as they visited the Valencia region, where more than 200 people have died in devastating floods.
They hold the eggs internally for several weeks, providing nutrients, and then lay them and cover them like birds.
