A is for Amniotic Egg!

Amniotic eggs are eggs produced by reptiles, birds, and other egg laying mammals. Their eggs are usually calcium based or leathery. The embryo is developed inside the amnion. 
This picture is a good representation of an amniotic egg because this bird egg has a calcium based shell in which the embryo was developed inside of the bird.
