What are organisms that lay eggs?

Organisms that lay eggs are known as oviparous species. This group includes a wide variety of animals such as birds, reptiles, amphibians, fish, and many invertebrates. Egg-laying allows these organisms to reproduce and is often accompanied by protective adaptations, such as hard shells in birds and reptiles or gelatinous coverings in amphibians. The development of the embryos occurs outside the mother's body, often in a safe environment to increase survival chances.
