What is an amniotic egg?

An amniotic egg is a type of egg produced by reptiles, birds, and some mammals that have an amniotic membrane surrounding the embryo. This membrane provides protection and allows the embryo to develop in a terrestrial environment without drying out.

Amniotic eggs have several layers including a shell, albumin (egg white), yolk, and membranes that protect the embryo and provide it with nutrients. The shell is typically hard and porous to allow for gas exchange and protect the developing embryo.

These eggs are laid by the parent and incubated externally until the embryo is fully developed and ready to hatch. This type of reproduction is known as oviparous reproduction.

Amniotic eggs are essential for the survival of many species as they allow for reproduction in arid or terrestrial environments where there is limited access to water. They also provide a safe and protected environment for the developing embryo to grow and develop.
