Oviparous animal: reproduction includes egg deposit

What they are - biological definition

Oviparous are animals whose reproduction includes the laying of eggs in the external environment.

Summary of characteristics and information on oviparous

Oviparous females of many species lay their already fertilized eggs, as with many birds and insects.

In many aquatic species external fertilization is common and therefore the eggs that are expelled by the female are not yet fertilized. The disadvantage of this type of breeding is that eggs are at the mercy of predators, and therefore a very high mortality occurs.

However, there are different strategies: some species, such as cod, lay a large number of eggs, leaving them alone; others, such as turtles, lay their eggs in more protected regions so that they are not found by predators.

The vast majority of birds, as well as some species of fish and reptiles, usually lay their eggs in nests and watch over them throughout their development. The greater the protection of its parents, the fewer eggs the female lays.

Examples of oviparous animal species:

- All birds

- Snakes and snakes

- Most fish
