egglaying
Hatching from shells
Egglaying describes the reproductive method of animals that produce eggs which develop and hatch outside the mother's body.
Birds, most reptiles, fish, and insects are egglaying species.
The term distinguishes these animals from those that give birth to live young: Platypuses are among the few egglaying mammals.
